From 0916b38b8300c41f66c2f22e79c77f3c5f6f4cb7 Mon Sep 17 00:00:00 2001 From: Teravus Ovares Date: Fri, 17 Oct 2008 23:19:00 +0000 Subject: * Fix an over compensation for bounciness on flat Primitive * Implement the linear impulse portion of llPushObject. We should have a lsl compatible implementation of that portion of the push. Angular.. well. still have yet to implement a torque accumulator. * llPushObject respects the region and parcel settings for Restrict Push, it also respects GodMode as is defined in the LSL spec. --- .../Shared/Api/Implementation/LSL_Api.cs | 172 ++++++++++++++++++++- 1 file changed, 169 insertions(+), 3 deletions(-) (limited to 'OpenSim/Region/ScriptEngine/Shared/Api/Implementation/LSL_Api.cs') diff --git a/OpenSim/Region/ScriptEngine/Shared/Api/Implementation/LSL_Api.cs b/OpenSim/Region/ScriptEngine/Shared/Api/Implementation/LSL_Api.cs index 6a6109b..956a500 100644 --- a/OpenSim/Region/ScriptEngine/Shared/Api/Implementation/LSL_Api.cs +++ b/OpenSim/Region/ScriptEngine/Shared/Api/Implementation/LSL_Api.cs @@ -3456,10 +3456,176 @@ namespace OpenSim.Region.ScriptEngine.Shared.Api public void llPushObject(string target, LSL_Vector impulse, LSL_Vector ang_impulse, int local) { m_host.AddScriptLPS(1); - SceneObjectPart targ = World.GetSceneObjectPart((UUID)target); - if (targ == null) + bool pushrestricted = World.RegionInfo.RegionSettings.RestrictPushing; + bool pushAllowed = false; + + bool pusheeIsAvatar = false; + UUID targetID = UUID.Zero; + + if (!UUID.TryParse(target,out targetID)) return; - targ.ApplyImpulse(new Vector3((float)impulse.x, (float)impulse.y, (float)impulse.z), local != 0); + + ScenePresence pusheeav = null; + //SceneObjectPart pusheeob = null; + EntityBase obj = null; + Vector3 PusheePos = Vector3.Zero; + SceneObjectPart pusheeob = null; + + List avatars = World.GetAvatars(); + + foreach (ScenePresence avatar in avatars) + { + if (avatar.UUID == targetID) + { + pusheeIsAvatar = true; + + // Pushee doesn't have a physics actor + if (avatar.PhysicsActor == null) + return; + + // Pushee is in GodMode this pushing object isn't owned by them + if (avatar.GodLevel > 0 && m_host.OwnerID != targetID) + return; + + pusheeav = avatar; + + // Find pushee position + // Pushee Linked? + if (pusheeav.ParentID != 0) + { + SceneObjectPart parentobj = World.GetSceneObjectPart(pusheeav.ParentID); + if (parentobj != null) + { + PusheePos = parentobj.AbsolutePosition; + } + else + { + PusheePos = pusheeav.AbsolutePosition; + } + } + else + { + PusheePos = pusheeav.AbsolutePosition; + } + + obj = (EntityBase)pusheeav; + break; + } + } + + if (!pusheeIsAvatar) + { + pusheeob = World.GetSceneObjectPart((UUID)target); + + // We can't find object + if (pusheeob == null) + return; + + // Object not pushable.
