From 3b2b785a461eba34c26a45be246c2baef2820e39 Mon Sep 17 00:00:00 2001 From: Robert Adams Date: Thu, 13 Dec 2012 12:42:25 -0800 Subject: BulletSim: Add 'BulletSimData' which separates structures created for the operation of BulletSim and those defintiions/structures defined so they can be used in the unmanaged world. Consolidate setting of collision flags so implementation is not scattered. --- .../Region/Physics/BulletSPlugin/BSCharacter.cs | 5 +- OpenSim/Region/Physics/BulletSPlugin/BSPrim.cs | 29 +-- .../Physics/BulletSPlugin/BSTerrainHeightmap.cs | 5 +- .../Physics/BulletSPlugin/BSTerrainManager.cs | 4 +- .../Region/Physics/BulletSPlugin/BSTerrainMesh.cs | 5 +- .../Region/Physics/BulletSPlugin/BulletSimAPI.cs | 183 +------------ .../Region/Physics/BulletSPlugin/BulletSimData.cs | 282 +++++++++++++++++++++ 7 files changed, 308 insertions(+), 205 deletions(-) create mode 100755 OpenSim/Region/Physics/BulletSPlugin/BulletSimData.cs (limited to 'OpenSim') diff --git a/OpenSim/Region/Physics/BulletSPlugin/BSCharacter.cs b/OpenSim/Region/Physics/BulletSPlugin/BSCharacter.cs index c8aad8d..0defb24 100644 --- a/OpenSim/Region/Physics/BulletSPlugin/BSCharacter.cs +++ b/OpenSim/Region/Physics/BulletSPlugin/BSCharacter.cs @@ -167,9 +167,8 @@ public sealed class BSCharacter : BSPhysObject BulletSimAPI.UpdateSingleAabb2(PhysicsScene.World.ptr, PhysBody.ptr); // Do this after the object has been added to the world - BulletSimAPI.SetCollisionGroupMask2(PhysBody.ptr, - (uint)CollisionFilterGroups.AvatarGroup, - (uint)CollisionFilterGroups.AvatarMask); + PhysBody.collisionType = CollisionType.Avatar; + PhysBody.ApplyCollisionMask(); } public override void RequestPhysicsterseUpdate() diff --git a/OpenSim/Region/Physics/BulletSPlugin/BSPrim.cs b/OpenSim/Region/Physics/BulletSPlugin/BSPrim.cs index 19c29cc..c9c9c2c 100644 --- a/OpenSim/Region/Physics/BulletSPlugin/BSPrim.cs +++ b/OpenSim/Region/Physics/BulletSPlugin/BSPrim.cs @@ -661,14 +661,7 @@ public sealed class BSPrim : BSPhysObject BulletSimAPI.UpdateSingleAabb2(PhysicsScene.World.ptr, PhysBody.ptr); // Collision filter can be set only when the object is in the world - if (PhysBody.collisionGroup != 0 || PhysBody.collisionMask != 0) - { - if (!BulletSimAPI.SetCollisionGroupMask2(PhysBody.ptr, (uint)PhysBody.collisionGroup, (uint)PhysBody.collisionMask)) - { - PhysicsScene.Logger.ErrorFormat("{0} Failure setting prim collision mask. localID={1}, grp={2:X}, mask={3:X}", - LogHeader, LocalID, PhysBody.collisionGroup, PhysBody.collisionMask); - } - } + PhysBody.ApplyCollisionMask(); // Recompute any linkset parameters. // When going from non-physical to physical, this re-enables the constraints that @@ -713,11 +706,11 @@ public sealed class BSPrim : BSPhysObject // Start it out sleeping and physical actions could wake it up.
