From c44a8e9f925c0195c4754c5e763af06dae657b53 Mon Sep 17 00:00:00 2001 From: Robert Adams Date: Fri, 25 Jan 2013 10:17:20 -0800 Subject: BulletSim: finish the post step event for physical object actions. Modify vehicle to use post step event for logging. --- OpenSim/Region/Physics/BulletSPlugin/BSDynamics.cs | 14 ++++- .../Region/Physics/BulletSPlugin/BSPhysObject.cs | 66 ++++++++++++++++++---- OpenSim/Region/Physics/BulletSPlugin/BSPrim.cs | 6 ++ 3 files changed, 73 insertions(+), 13 deletions(-) (limited to 'OpenSim/Region/Physics/BulletSPlugin') diff --git a/OpenSim/Region/Physics/BulletSPlugin/BSDynamics.cs b/OpenSim/Region/Physics/BulletSPlugin/BSDynamics.cs index 7ad7c89..a369c1f 100644 --- a/OpenSim/Region/Physics/BulletSPlugin/BSDynamics.cs +++ b/OpenSim/Region/Physics/BulletSPlugin/BSDynamics.cs @@ -583,6 +583,8 @@ namespace OpenSim.Region.Physics.BulletSPlugin // Some of the properties of this prim may have changed. // Do any updating needed for a vehicle + Vector3 m_physicsLinearFactor = new Vector3(0.2f, 0.2f, 0.2f);
