Introduction</H1 ><P >The Linden Scripting Language (LSL) is a simple, powerful language used to attach behaviors to the objects found in Second Life. It follows the familiar syntax of a c/Java style language, with an implicit state machine for every script.</P ><P >Multiple scripts may also be attached to the same object, allowing a style of small, single-function scripts to evolve. This leads to scripts that perform specific functions ("hover", "follow", etc.) and allows them to be combined to form new behaviors.</P ><P >The text of the script is compiled into an executable byte code, much like Java. This byte code is then run within a virtual machine on the simulator. Each script receives a time slice of the total simulator time allocated to scripts, so a simulator with many scripts would allow each individual script less time rather than degrading its own performance. In addition, each script executes within its own chunk of memory, preventing scripts from writing into protected simulator memory or into other scripts, making it much harder for scripts to crash the simulator.</P ><P >This tutorial introduces the reader to the basic features of LSL, how to edit and apply your scripts, and a complete reference for standard linden constants, events, and library functions.</P ></DIV ><DIV CLASS="chapter" ><HR><H1 ><A NAME="AEN33" ></A >Chapter 2. Getting Started</H1 ><P >You're probably wondering what you can do with LSL, and how quickly you can do it. We'll start with some simple examples, dissect them, and introduce you the script development process while we're at it.</P ><DIV CLASS="section" ><HR><H2 CLASS="section" ><A NAME="AEN36" >2.1. Hello Avatar</A ></H2 ><P >Continuing a long tradition of getting started by looking at a script that says "Hello", we'll do just that. Though obviously not a particularly useful example on it's own, this example will introduce us to:</P ><P ></P ><UL ><LI ><P >Creating a basic script</P ></LI ><LI ><P >Script states</P ></LI ><LI ><P >Calling functions</P ></LI ><LI ><P >Script events</P ></LI ><LI ><P >Applying a script to an object</P ></LI ></UL ><DIV CLASS="section" ><HR><H3 CLASS="section" ><A NAME="AEN50" >2.1.1. Creating the Script</A ></H3 ><P >Start by opening your inventory and selecting 'Create|New Script' from the inventory pull down menu. This will create an empty script called 'New Script' in your 'Scripts' folder. Double click on the text or icon of the script to open the script in the built in editor. When you open the script, the viewer will automatically insert a basic skeleton for lsl. It should look like:</P ><P ><PRE CLASS="programlisting" > default { state_entry() { llSay(0, "Hello, Avatar!"); } touch_start(integer total_number) { llSay(0, "Touched."); } } </PRE ></P ><P >A casual inspection of this script reveals that this script probably says 'Hello, Avatar!' when it enters some state, and it says 'Touched.' when it is touched. But since this is also probably the first time you have seen a script we'll dissect this short listing, explaining each segment individually.</P ></DIV ><DIV CLASS="section" ><HR><H3 CLASS="section" ><A NAME="AEN56" >2.1.2. Default State</A ></H3 ><P ><DIV CLASS="informalexample" ><P ></P ><A NAME="AEN59" ></A ><PRE CLASS="programlisting" > default { ... } </PRE ><P ></P ></DIV ></P ><P >All LSL scripts have a simple implicit state machine with one or more states. All scripts must have a default state, so if there is only one state, it will be the 'default' state. When a script is first started or reset, it will start out in the default state.</P ><P >The default state is declared by placing the default at the root level of the document, and marking the beginning with an open brace '{' and ending with a close brace '}'. Because of it's privileged status, you do not declare that it is fact a state like you normally would with other states.</P ><P >Every time you enter a state, the script engine will automatically call the state_entry() event and execute the code found there. On state exit, the script engine will automatically call the state_exit() event before calling the next state's state_entry handler. In our example, we call the <A HREF="#AEN3640" >llSay()</A > function in state_entry() and do not bother to define a state_exit() handler. the state entry and exit handlers are a convenient place to initialize state data and clean up state specific data such as listen event callback.</P ><P >You can read more about the default state, and how to create and utilize other states in the <A HREF="#AEN427" >states chapter</A >.</P ></DIV ><DIV CLASS="section" ><HR><H3 CLASS="section" ><A NAME="AEN67" >2.1.3. Functions</A ></H3 ><P >The language comes with well over 200 <A HREF="#AEN999" >built in functions</A > which allow scripts and objects to interact with their environment. All of the built in functions start with 'll'.</P ><P >The example calls the <A HREF="#AEN3640" >llSay()</A > function twice, which is used to emit text on the specified channel. </P ><DIV CLASS="funcsynopsis" ><P ></P ><A NAME="AEN73" ></A ><P ><CODE ><CODE CLASS="FUNCDEF" >llSay</CODE >( integer channel string text );</CODE ></P ><P ></P ></DIV ><P >Say text on channel. Channel 0 is the public chat channel that all avatars see as chat text. Channels 1 to 2,147,483,648 are private channels that aren't sent to avatars but other scripts can listen for.</P ><P >You can define your own functions as long as the name does not conflict with a reserved word, built in constant, or built in function.</P ></DIV ><DIV CLASS="section" ><HR><H3 CLASS="section" ><A NAME="AEN82" >2.1.4.

As an example of how to use the right hand rule, consider a positive rotation about the roll axis. To help visualize how such a rotation would move the airplane, place your right thumb parallel to the plane's roll-axis such that the thumb points in the positive x-direction, then curl the four fingers into a fist. Your fingers will be pointing in the direction that the plane will spin.</P ><P ><DIV CLASS="informalexample" ><P ></P ><A NAME="AEN823" ></A ><PRE CLASS="programlisting" > .-.--.--.--. __ / / / / _ \ / \ (-(- (- (- ( | _________|______\ axis of \.\._\._\._) | | / rotation | \:__,---. \|/ | | + positive \ .,_.___.' rotation \_ ^ `.__,/ | / | | </PRE ><P ></P ></DIV ></P ><P > Many of the parameters that control a vehicle's behavior are of the form: VEHICLE_BEHAVIOR_TIMESCALE. A behavior's "timescale" can usually be understood as the time for the behavior to push, twist, or otherwise affect the vehicle such that the difference between what it is doing, and what it is supposed to be doing, has been reduced to 1/e of what it was, where "e" is the natural exponent (approximately 2.718281828). In other words, it is the timescale for exponential decay toward full compliance to the desired behavior. When you want the vehicle to be very responsive use a short timescale of one second or less, and if you want to disable a behavior then set the timescale to a very large number like 300 (5 minutes) or more. Note, for stability reasons, there is usually a limit to how small a timescale is allowed to be, and is usually on the order of a tenth of a second. Setting a timescale to zero is safe and is always equivalent to setting it to its minimum. Any feature with a timescale can be effectively disabled by setting the timescale so large that it would take them all day to have any effect.</P ></DIV ><DIV CLASS="section" ><HR><H2 CLASS="section" ><A NAME="AEN826" >11.4.

Linear and Angular Deflection</A ></H2 ><P >A common feature of real vehicles is their tendency to move along "preferred axes of motion". That is, due to their wheels, wings, shape, or method of propulsion they tend to push or redirect themselves along axes that are static in the vehicle's local frame. This general feature defines a class of vehicles and included in this category a common dart is a "vehicle": it has fins in the back such that if it were to tumble in the air it would eventually align itself to move point-forward -- we'll call this alignment effect <SPAN CLASS="emphasis" ><I CLASS="emphasis" >angular deflection</I ></SPAN >.</P ><P >A wheeled craft exhibits a different effect: when a skateboard is pushed in some direction it will tend to redirect the resultant motion along that which it is free to roll -- we'll call this effect <SPAN CLASS="emphasis" ><I CLASS="emphasis" > linear deflection</I ></SPAN >.</P ><P >So a typical Second Life vehicle is an object that exhibits linear and/or angular deflection along the "preferential axes of motion". The default preferential axes of motion are the local x- (at), y- (left), and z- (up) axes of the <SPAN CLASS="emphasis" ><I CLASS="emphasis" >local frame</I ></SPAN > of the vehicle's root primitive. The deflection behaviors relate to the x-axis (at): linear deflection will tend to rotate its velocity until it points along it's positive local x-axis while the angular deflection will tend to reorient the vehicle such that it's x-axis points in the direction that it is moving. The other axes are relevant to vehicle behaviors that are described later, such as the <A HREF="#AEN938" >vertical attractor</A > which tries to keep a vehicle's local z-axis pointed toward the world z-axis (up). The vehicle axes can be rotated relative to the object's actual local axes by using the <A HREF="#AEN990" >VEHICLE_REFERENCE_FRAME</A > parameter, however that is an advanced feature and is covered in detail in a later section of these documents.</P ><P >Depending on the vehicle it might be desirable to have lots of linear and/or angular deflection or not. The speed of the deflections are controlled by setting the relevant parameters using the <A HREF="#AEN4235" >llSetVehicleFloatParam</A > script call. Each variety of deflection has a "timescale" parameter that determines how quickly a full deflection happens. Basically the timescale it the time coefficient for exponential decay toward full deflection. So, a vehicle that deflects quickly should have a small timescale. For instance, a typical dart might have a angular deflection timescale of a couple of seconds but a linear deflection of several seconds; it will tend to reorient itself before it changes direction. To set the deflection timescales of a dart you might use the lines below:</P ><P ><DIV CLASS="informalexample" ><P ></P ><A NAME="AEN850" ></A ><PRE CLASS="programlisting" > llSetVehicleFloatParam(VEHICLE_ANGULAR_DEFLECTION_TIMESCALE, 2.0); llSetVehicleFloatParam(VEHICLE_LINEAR_DEFLECTION_TIMESCALE, 6.0); </PRE ><P ></P ></DIV ></P ><P > Each variety of deflection has an "efficiency" parameter that is a slider between 0.0 and 1.0. Unlike the other efficiency parameters of other vehicle behaviors, the deflection efficiencies do not slide between "bouncy" and "damped", but instead slide from "no deflection whatsoever" (0.0) to "maximum deflection" (1.0). That is, they behave much like the deflection timescales, however they are normalized to the range between 0.0 and 1.0.</P ></DIV ><DIV CLASS="section" ><HR><H2 CLASS="section" ><A NAME="AEN853" >11.6. Moving and Steering the Vehicle</A ></H2 ><P >Once enabled, a vehicle can be pushed and rotated by external forces and/or from script calls such as <A HREF="#AEN1070" >llApplyImpulse</A >, however linear and angular motors have been built in to make motion smoother and easier to control. Their directions can be set using the <A HREF="#AEN4274" >llSetVehicleVectorParam</A > call. For example, to make the vehicle try to move at 5 meters/second along its local x-axis (the default look-at direction) you would put the following line in your script:</P ><P ><DIV CLASS="informalexample" ><P ></P ><A NAME="AEN859" ></A ><PRE CLASS="programlisting" > llSetVehicleVectorParam(VEHICLE_LINEAR_MOTOR_DIRECTION, <5, 0, 0>); </PRE ><P ></P ></DIV ></P ><P >The motor strength is not the full story, since you can also control how fast the motor engages (VEHICLE_LINEAR_MOTOR_TIMESCALE) and there is a parameter that causes the motor's effectiveness to decay over time (VEHICLE_LINEAR_MOTOR_DECAY_TIMESCALE).</P ><P >Steering the vehicle involves setting the VEHICLE_ANGULAR_MOTOR_DIRECTION and related parameters. It is also possible to set some flags that allow the angular motor slave to your camera view when in mouselook.</P ><P >For more details about the vehicle motors read the sections on the <A HREF="#AEN866" >linear </A > and <A HREF="#AEN898" >angular</A > motors below.</P ></DIV ><DIV CLASS="section" ><HR><H2 CLASS="section" ><A NAME="AEN866" >11.7. The Linear Motor</A ></H2 ><P >The parameters that control the linear motor are:</P ><P ><P ></P ><UL ><LI STYLE="list-style-type: opencircle" ><P > VEHICLE_LINEAR_MOTOR_DIRECTION</P ><P >A vector. It is the velocity (meters/sec) that the vehicle will try to attain. It points in the vehicle's local frame, and has a maximum length of 40.</P ></LI ><LI STYLE="list-style-type: opencircle" ><P > VEHICLE_LINEAR_MOTOR_OFFSET</P ><P >A vector. It is the offset point from the vehicle's center of mass at which the linear motor's impulse is applied. This allows the linear motor to also cause rotational torque. It is in the vehicle's local frame and its maximum length is 100 meters! No need to worry about stability -- if the vehicle starts to spin too fast (greater than about 4*PI radians per second) then angular velocity damping will kick in. The reason the offset is allowed to be so large is so that it can compete with the other vehicle behaviors such as <A HREF="#vehicle_angular_deflection" >angular deflection</A > and the <A HREF="#AEN938" >vertical attractor</A >. Some of the other vehicle behaviors may drastically reduce the effective torque from the linear motor offset, in which case a longer leverage arm may help.</P ></LI ><LI STYLE="list-style-type: opencircle" ><P > VEHICLE_LINEAR_MOTOR_TIMESCALE</P ><P >A float.

Its minimum value is approximately 0.06 seconds.</P ></LI ><LI STYLE="list-style-type: opencircle" ><P > VEHICLE_LINEAR_MOTOR_DECAY_TIMESCALE</P ><P >A float. The effectiveness of the motor will exponentially decay over this timescale, but the effectiveness will be reset whenever the motor's value is explicitly set. The maximum value of this decay timescale is 120 seconds, and this timescale is always in effect.</P ></LI ></UL ></P ><P >The flags that affect the linear motor are:</P ><P ><P ></P ><UL ><LI STYLE="list-style-type: opencircle" ><P >VEHICLE_FLAG_LIMIT_MOTOR_UP</P ><P >Useful for "ground vehicles". Setting this flag will clamp the z-component of the linear motor (in world frame) to prevent it from defeating gravity.</P ></LI ></UL ></P ><P >Setting the motor speed is not enough to enable all interesting vehicles. For example, some will want a car that immediately gets up to the speed they want, while others will want a boat that slowly climbs up to its maximum velocity. To control this effect the VEHICLE_LINEAR_MOTOR_TIMESCALE parameter can be used. Basically the "timescale" of a motor is the time constant for the vehicle to exponentially accelerate toward its full speed.</P ><P >What would happen if you were to accidentally set the vehicle's linear velocity to maximum possible speed and then let go? It would run away and never stop, right? Not necessarily: an automatic "motor decay" has been built in such that all motors will gradually decrease their effectiveness after being set.</P ><P >Each time the linear motor's vector is set its "grip" immediately starts to decay exponentially with a timescale determined by the VEHICLE_LINEAR_MOTOR_DECAY_TIMESCALE, such that after enough time the motor ceases to have any effect. This decay timescale serves two purposes. First, since it <SPAN CLASS="emphasis" ><I CLASS="emphasis" >cannot</I ></SPAN > be set longer than 120 seconds, and is <SPAN CLASS="emphasis" ><I CLASS="emphasis" >always</I ></SPAN > enabled it guarantees that a vehicle will not push itself about forever in the absence of active control (from keyboard commands or some logic loop in the script). Second, it can be used to push some vehicles around using a simple impulse model. That is, rather than setting the motor "on" or "off" depending on whether a particular key is pressed "down" or "up" the decay timescale can be set short and the motor can be set "on" whenever the key transitions from "up" to "down" and allowed to automatically decay.</P ><P > Since the motor's effectiveness is reset whenever the motor's vector is set, then setting it to a vector of length zero is different from allowing it to decay completely. The first case will cause the vehicle to try to reach zero velocity, while the second will leave the motor impotent.</P ><P >The two motor timescales have very similar names, but have different effects, so try not to get them confused. VEHICLE_LINEAR_MOTOR_TIMESCALE is the time for motor to "win", and VEHICLE_LINEAR_MOTOR_DECAY_TIMESCALE is the time for the motor's "effectiveness" to decay toward zero. If you set one when you think you are changing the other you will have frustrating results. Also, if the motor's decay timescale is shorter than the regular timescale, then the effective magnitude of the motor vector will be diminished.</P ></DIV ><DIV CLASS="section" ><HR><H2 CLASS="section" ><A NAME="AEN898" >11.8.

One way would be for the script to grab keyboard input and to explicitly turn the motor on/off based on which keys are pressed. When steering this way you probably don't want it to turn very far or for very long. One way to do it using the angular motor would be to leave the decay timescale long, enable a significant amount of angular friction (to quickly slow the vehicle down when the motor is turned off) then set the angular motor to a large vector on a key press, and set it to zero when the key is released. That has the effect of making the vehicle unresponsive to external collisions, due to the angular friction.</P ><P >Another way to do it is to set the VEHICLE_ANGULAR_MOTOR_DECAY_TIMESCALE to a short value and push the vehicle about with a more impulsive method that sets the motor fast on a key press down (and optionally setting the motor to zero on a key up) relying on the automatic exponential decay of the motor's effectiveness rather than a constant angular friction.</P ><P >Finally, it may be possible to discard the angular motor entirely and use the VEHICLE_LINEAR_MOTOR_OFFSET. Whenever the offset has a component that is perpendicular to the direction of the linear motor the vehicle will rotate as it travels. Note, with the incorrect values for offset and strength the linear motor effect can easily cause the vehicle to tumble and spin uncontrollably, so experiement with small offsets first!.</P ><P >Setting the angular motor to zero magnitude is different from allowing it to decay. When the motor completely decays it no longer affects the motion of the vehicle, however setting it to zero will reset the "grip" of the vehicle and will make the vehicle try to achieve zero angular velocity. </P ><P >Many real vehicles bank (roll about their forward axis) to effect a turn, such as motorcycles and airplanes. To make it easier to build banking vehicles there is <A HREF="#AEN949" >banking behavior</A > available which can be controlled by setting other parameters and is described in more detail here.</P ><P >It is also possible to make a <A HREF="#AEN921" >vehicle turn in response to changing the camera view</A > (right now this only works in mouselook).</P ></DIV ><DIV CLASS="section" ><HR><H2 CLASS="section" ><A NAME="AEN921" >11.9.

When used properly this feature has the advantage of being able to provide simple and stable steering that is resilient to bad render frame rates on the client. </P ><P >The flags that affect the angular motor are:</P ><P ><P ></P ><UL ><LI STYLE="list-style-type: opencircle" ><P > VEHICLE_FLAG_MOUSELOOK_STEER</P ><P >Steer the vehicle using the mouse. Use this flag to make the angular motor try to make the vehicle turn such that its local x-axis points in the same direction as the client-side camera.</P ></LI ><LI STYLE="list-style-type: opencircle" ><P > VEHICLE_FLAG_MOUSELOOK_BANK</P ><P >Same as above, but relies on banking. It remaps left-right motions of the client camera (also known as "yaw") to rotations about the vehicle's local x-axis (also known as "roll"). </P ></LI ><LI STYLE="list-style-type: opencircle" ><P > VEHICLE_FLAG_CAMERA_DECOUPLED</P ><P >Makes mouselook camera rotate independently of the vehicle. By default the client mouselook camera will rotate about with the vehicle, however when this flag is set the camera direction is independent of the vehicle's rotation.</P ></LI ></UL ></P ><P >When using the VEHICLE_FLAG_MOUSELOOK_STEER (or VEHICLE_FLAG_MOUSELOOK_BANK) the meaning of the VEHICLE_ANGULAR_MOTOR_DIRECTION parameter subtly changes. Instead of representing the "angular velocity" of the motor the components of the parameter scale the "measured angular velocity" (as determined by the rotation between the client's camera view direction and the forward-axis of the vehicle) to compute the "final angular velocity". That is, suppose you set the angular motor to <0, 0, 5>, then moved the camera view to be PI/4 radians to the left of the vehicle's forward axis, and down PI/8 toward the ground. The measured angular velocity would be <0, -PI/8, PI/4> radians/second, but the final velocity would be <0, 0, 5*PI/4>... the vehicle will turn left, but will not dip its nose down. Thus, by setting a component of the VEHICLE_ANGULAR_MOTOR_DIRECTION to zero, one can negate the pitch or yaw response of the motor, or even scale one to be much more responsive than the other. </P ><P >The VEHICLE_ANGULAR_MOTOR_TIMESCALE still has an effect when using mouselook control, and scales the global responsiveness of the angular motor. The VEHICLE_ANGULAR_MOTOR_DECAY_TIMESCALE, on the other hand, is ignored when using mouselook controls.</P ></DIV ><DIV CLASS="section" ><HR><H2 CLASS="section" ><A NAME="AEN938" >11.10. The Vertical Attractor</A ></H2 ><P >Some vehicles, like boats, should always keep their up-side up. This can be done by enabling the "vertical attractor" behavior that springs the vehicle's local z-axis to the world z-axis (a.k.a. "up"). To take advantage of this feature you would set the VEHICLE_VERTICAL_ATTRACTION_TIMESCALE to control the period of the spring frequency, and then set the VEHICLE_VERTICAL_ATTRACTION_EFFICIENCY to control the damping. An efficiency of 0.0 will cause the spring to wobble around its equilibrium, while an efficiency of 1.0 will cause the spring to reach it's equilibrium with exponential decay.</P ><P ><DIV CLASS="informalexample" ><P ></P ><A NAME="AEN942" ></A ><PRE CLASS="programlisting" > llSetVehicleVectorParam(VEHICLE_VERTICAL_ATTRACTION_TIMESCALE, 4.0); llSetVehicleVectorParam(VEHICLE_VERTICAL_ATTRACTION_EFFICIENCY, 0.5); </PRE ><P ></P ></DIV ></P ><P >The vertical attractor is disabled by setting its timescale to anything larger than 300 seconds.</P ><P >Note that by default the vertical attractor will prevent the vehicle from diving and climbing. So, if you wanted to make a airplane you would probably want to unlock the attractor around the pitch axis by setting the VEHICLE_FLAG_LIMIT_ROLL_ONLY bit:</P ><P ><DIV CLASS="informalexample" ><P ></P ><A NAME="AEN947" ></A ><PRE CLASS="programlisting" > llSetVehicleFlags(VEHICLE_FLAG_LIMIT_ROLL_ONLY); </PRE ><P ></P ></DIV ></P ></DIV ><DIV CLASS="section" ><HR><H2 CLASS="section" ><A NAME="AEN949" >11.11. Banking</A ></H2 ><P >The <A HREF="#AEN938" > vertical attractor</A > feature must be enabled in order for the banking behavior to function. The way banking works is this: a rotation around the vehicle's roll-axis will produce a angular velocity around the yaw-axis, causing the vehicle to turn. The magnitude of the yaw effect will be proportional to the VEHICLE_BANKING_EFFICIENCY, the angle of the roll rotation, and sometimes the vehicle's velocity along it's preferred axis of motion.</P ><P >The VEHICLE_BANKING_EFFICIENCY can vary between -1 and +1. When it's positive then any positive rotation (by the right-hand rule) about the roll-axis will effect a (negative) torque around the yaw-axis, making it turn to the right -- that is the vehicle will lean into the turn, which is how real airplanes and motorcycle's work. Negating the banking coefficient will make it so that the vehicle leans to the outside of the turn (not very "physical" but might allow interesting vehicles so why not?).</P ><P >The VEHICLE_BANKING_MIX is a fake (i.e. non-physical) parameter that is useful for making banking vehicles do what you want rather than what the laws of physics allow. For example, consider a real motorcycle... it must be moving forward in order for it to turn while banking, however video-game motorcycles are often configured to turn in place when at a dead stop -- because they're often easier to control that way using the limited interface of the keyboard or game controller. The VEHICLE_BANKING_MIX enables combinations of both realistic and non-realistic banking by functioning as a slider between a banking that is correspondingly totally static (0.0) and totally dynamic (1.0). By "static" we mean that the banking effect depends only on the vehicle's rotation about it's roll-axis compared to "dynamic" where the banking is also proportional to it's velocity along it's roll-axis. Finding the best value of the "mixture" will probably require trial and error.</P ><P >The time it takes for the banking behavior to defeat a pre-existing angular velocity about the world z-axis is determined by the VEHICLE_BANKING_TIMESCALE. So if you want the vehicle to bank quickly then give it a banking timescale of about a second or less, otherwise you can make a sluggish vehicle by giving it a timescale of several seconds.</P ></DIV ><DIV CLASS="section" ><HR><H2 CLASS="section" ><A NAME="AEN956" >11.12.

Most vehicles will work best with short hover timescales of a few seconds or less. The shorter the timescale, the faster the vehicle will slave to is target height. Note, that if the values of VEHICLE_LINEAR_FRICTION_TIMESCALE may affect the speed of the hover.</P ><P >Hover is independent of buoyancy, however the VEHICLE_BUOYANCY should be set to 1.0, otherwise the vehicle will not lift itself off of the ground until the VEHICLE_HOVER_HEIGHT is made large enough to counter the acceleration of gravity, and the vehicle will never float all the way to its target height. </P ><P >The VEHICLE_HOVER_EFFICIENCY can be thought of as a slider between bouncy (0.0) and smoothed (1.0). When in the bouncy range the vehicle will tend to hover a little lower than its target height and the VEHICLE_HOVER_TIMESCALE will be approximately the oscillation period of the bounce (the real period will tend to be a little longer than the timescale).</P ><P >For performance reasons, until improvements are made to the Second Life physics engine the vehicles can only hover over the terrain and water, so they will not be able to hover above objects made out of primitives, such as bridges and houses. By default the hover behavior will float over terrain and water, however this can be changed by setting some flags: </P ><P >If you wanted to make a boat you should set the <A HREF="#const_vehicle_flag_hover_water_only" > VEHICLE_HOVER_WATER_ONLY </A > flag, or if you wanted to drive a hover tank under water you would use the <A HREF="#const_vehicle_flag_hover_terrain_only" > VEHICLE_HOVER_TERRAIN_ONLY </A > flag instead. Finally, if you wanted to make a submarine or a balloon you would use the <A HREF="#const_vehicle_flag_hover_global_height" > VEHICLE_FLAG_HOVER_GLOBAL_HEIGHT</A >. Note that the flags are independent of each other and that setting two contradictory flags will have undefined behavior. The flags are set using the script call llSetVehicleFlags().</P ><P >The VEHICLE_HOVER_HEIGHT determines how high the vehicle will hover over the terrain and/or water, or the global height, and has a maximum value of 100 meters. Note that for hovering purposes the "center" of the vehicle is its "center of mass" which is not always obvious to the untrained eye, and it changes when avatar's sit on the vehicle.</P ></DIV ><DIV CLASS="section" ><HR><H2 CLASS="section" ><A NAME="AEN990" >11.15. Reference Frame</A ></H2 ><P >The vehicle relies on the x- (at), y- (left), and z- (up) axes in order to figure out which way it prefers to move and which end is up. By default these axes are identical to the local axes of the root primitive of the object, however this means that the vehicle's root primitive must, by default, be oriented to agree with the designed at, left, and up axes of the vehicle. But, what if the vehicle object was already pre-built with the root primitive in some non-trivial orientation relative to where the vehicle as a whole should move? This is where the VEHICLE_REFERENCE_FRAME parameter becomes useful; the vehicle's axes can be arbitrarily reoriented by setting this parameter. </P ><P >As an example, suppose you had built a rocket out of a big cylinder, a cone for the nose, and some stretched cut boxes for the fins, then linked them all together with the cylinder as the root primitive. Ideally the rocket would move nose-first, however the cylinder's axis of symmetry is its local z-axis while the default "at-axis" of the vehicle, the axis it will want to deflect to forward under angular deflection, is the local x-axis and points out from the curved surface of the cylinder. The script code below will rotate the vehicle's axes such that the local z-axis becomes the "at-axis" and the local negative x-axis becomes the "up-axis":</P ><P ><DIV CLASS="informalexample" ><P ></P ><A NAME="AEN995" ></A ><PRE CLASS="programlisting" > // rotate the vehicle frame -PI/2 about the local y-axis (left-axis) rotation rot = llEuler2Rot(0, PI/2, 0); llSetVehicleRotationParam(VEHICLE_REFERENCE_FRAME, rot); </PRE ><P ></P ></DIV ></P ><P >Another example of how the reference frame parameter could be used is to consider flying craft that uses the vertical attractor for stability during flying but wants to use VTOL (vertical takeoff and landing). During flight the craft's dorsal axis should point up, but during landing its nose-axis should be up. To land the vehicle: while the <A HREF="#AEN938" >vertical attractor</A > is in effect, rotate the existing VEHICLE_REFERENCE_FRAME by +PI/2 about the left-axis, then the vehicle will pitch up such that it's nose points toward the sky. The vehicle could be allowed to fall to the landing pad under friction, or a decreasing hover effect. </P ></DIV ></DIV ><DIV CLASS="appendix" ><HR><H1 ><A NAME="AEN999" ></A >Appendix A.
