From 291c7cdbcc80dc270418a4959ccfa0ed8cc0c190 Mon Sep 17 00:00:00 2001 From: Robert Adams Date: Wed, 31 Dec 2014 12:43:26 -0800 Subject: BulletSim: Add axis locking enabled through the ExtendedPhysics module. Allows locking of prim/linkset relative moving in each of the linear and angular axis. Limits on movement or rotation can be set. --- .../Scripting/ExtendedPhysics/ExtendedPhysics.cs | 98 ++++-- .../Physics/BulletSPlugin/BSActorLockAxis.cs | 121 ++++---- .../Physics/BulletSPlugin/BSLinksetCompound.cs | 5 +- .../Region/Physics/BulletSPlugin/BSPhysObject.cs | 13 +- OpenSim/Region/Physics/BulletSPlugin/BSPrim.cs | 334 ++++++++++++++++++++- 5 files changed, 474 insertions(+), 97 deletions(-) (limited to 'OpenSim/Region') diff --git a/OpenSim/Region/OptionalModules/Scripting/ExtendedPhysics/ExtendedPhysics.cs b/OpenSim/Region/OptionalModules/Scripting/ExtendedPhysics/ExtendedPhysics.cs index 9daf9d7..ff4afbf 100755 --- a/OpenSim/Region/OptionalModules/Scripting/ExtendedPhysics/ExtendedPhysics.cs +++ b/OpenSim/Region/OptionalModules/Scripting/ExtendedPhysics/ExtendedPhysics.cs @@ -66,6 +66,7 @@ public class ExtendedPhysics : INonSharedRegionModule public const string PhysFunctChangeLinkType = "BulletSim.ChangeLinkType"; public const string PhysFunctGetLinkType = "BulletSim.GetLinkType"; public const string PhysFunctChangeLinkParams = "BulletSim.ChangeLinkParams"; + public const string PhysFunctAxisLockLimits = "BulletSim.AxisLockLimits"; // ============================================================= @@ -176,6 +177,71 @@ public class ExtendedPhysics : INonSharedRegionModule return ret; } + // Code for specifying params. + // The choice if 14700 is arbitrary and only serves to catch parameter code misuse. + [ScriptConstant] + public const int PHYS_AXIS_LOCK_LINEAR = 14700; + [ScriptConstant] + public const int PHYS_AXIS_LOCK_LINEAR_X = 14701; + [ScriptConstant] + public const int PHYS_AXIS_LIMIT_LINEAR_X = 14702; + [ScriptConstant] + public const int PHYS_AXIS_LOCK_LINEAR_Y = 14703; + [ScriptConstant] + public const int PHYS_AXIS_LIMIT_LINEAR_Y = 14704; + [ScriptConstant] + public const int PHYS_AXIS_LOCK_LINEAR_Z = 14705; + [ScriptConstant] + public const int PHYS_AXIS_LIMIT_LINEAR_Z = 14706; + [ScriptConstant] + public const int PHYS_AXIS_LOCK_ANGULAR = 14707; + [ScriptConstant] + public const int PHYS_AXIS_LOCK_ANGULAR_X = 14708; + [ScriptConstant] + public const int PHYS_AXIS_LIMIT_ANGULAR_X = 14709; + [ScriptConstant] + public const int PHYS_AXIS_LOCK_ANGULAR_Y = 14710; + [ScriptConstant] + public const int PHYS_AXIS_LIMIT_ANGULAR_Y = 14711; + [ScriptConstant] + public const int PHYS_AXIS_LOCK_ANGULAR_Z = 14712; + [ScriptConstant] + public const int PHYS_AXIS_LIMIT_ANGULAR_Z = 14713; + [ScriptConstant] + public const int PHYS_AXIS_UNLOCK_LINEAR = 14714; + [ScriptConstant] + public const int PHYS_AXIS_UNLOCK_LINEAR_X = 14715; + [ScriptConstant] + public const int PHYS_AXIS_UNLOCK_LINEAR_Y = 14716; + [ScriptConstant] + public const int PHYS_AXIS_UNLOCK_LINEAR_Z = 14717; + [ScriptConstant] + public const int PHYS_AXIS_UNLOCK_ANGULAR = 14718; + [ScriptConstant] + public const int PHYS_AXIS_UNLOCK_ANGULAR_X = 14719; + [ScriptConstant] + public const int PHYS_AXIS_UNLOCK_ANGULAR_Y = 14720; + [ScriptConstant] + public const int PHYS_AXIS_UNLOCK_ANGULAR_Z = 14721; + [ScriptConstant] + public const int PHYS_AXIS_UNLOCK = 14722; + // physAxisLockLimits() + [ScriptInvocation] + public int physAxisLock(UUID hostID, UUID scriptID, object[] parms) + { + int ret = -1; + if (!Enabled) return ret; + + PhysicsActor rootPhysActor; + if (GetRootPhysActor(hostID, out rootPhysActor)) + { + object[] parms2 = AddToBeginningOfArray(rootPhysActor, null, parms); + ret = MakeIntError(rootPhysActor.Extension(PhysFunctAxisLockLimits, parms2)); + } + + return ret; + } + [ScriptConstant] public const int PHYS_LINKSET_TYPE_CONSTRAINT = 0; [ScriptConstant] @@ -187,7 +253,6 @@ public class ExtendedPhysics : INonSharedRegionModule public int physSetLinksetType(UUID hostID, UUID scriptID, int linksetType) { int ret = -1; - if (!Enabled) return ret; // The part that is requesting the change. @@ -259,34 +324,11 @@ public class ExtendedPhysics : INonSharedRegionModule int ret = -1; if (!Enabled) return ret; - // The part that is requesting the change. - SceneObjectPart requestingPart = BaseScene.GetSceneObjectPart(hostID); - - if (requestingPart != null) + PhysicsActor rootPhysActor; + if (GetRootPhysActor(hostID, out rootPhysActor)) { - // The type is is always on the root of a linkset. - SceneObjectGroup containingGroup = requestingPart.ParentGroup; - SceneObjectPart rootPart = containingGroup.RootPart; - - if (rootPart != null) - { - PhysicsActor rootPhysActor = rootPart.PhysActor; - if (rootPhysActor != null) - { - object[] parms2 = { rootPhysActor, null }; - ret = MakeIntError(rootPhysActor.Extension(PhysFunctGetLinksetType, parms2)); - } - else - { - m_log.WarnFormat("{0} physGetLinksetType: root part does not have a physics actor. rootName={1}, hostID={2}", - LogHeader, rootPart.Name, hostID); - } - } - else - { - m_log.WarnFormat("{0} physGetLinksetType: root part does not exist.
