From 5d098d8f17fe24d9ad2999ddce819787d02989ce Mon Sep 17 00:00:00 2001 From: Robert Adams Date: Tue, 15 Jan 2013 15:07:38 -0800 Subject: BulletSim: don't modify angular parameters when doing LIMIT_MOTOR_UP. It was a dumb idea to try and do a nose over feature for jumping cars anyway. Add better logging of native shape creation/reuse so can tell the difference. --- .../Region/Physics/BulletSPlugin/BSCharacter.cs | 2 +- OpenSim/Region/Physics/BulletSPlugin/BSDynamics.cs | 12 +++++------ .../Physics/BulletSPlugin/BSLinksetCompound.cs | 2 +- .../Physics/BulletSPlugin/BSShapeCollection.cs | 18 ++++++++-------- .../Region/Physics/BulletSPlugin/BulletSimTODO.txt | 24 +++++++++++----------- 5 files changed, 30 insertions(+), 28 deletions(-) (limited to 'OpenSim/Region/Physics/BulletSPlugin') diff --git a/OpenSim/Region/Physics/BulletSPlugin/BSCharacter.cs b/OpenSim/Region/Physics/BulletSPlugin/BSCharacter.cs index 2e900b3..87a06c1 100644 --- a/OpenSim/Region/Physics/BulletSPlugin/BSCharacter.cs +++ b/OpenSim/Region/Physics/BulletSPlugin/BSCharacter.cs @@ -215,7 +215,7 @@ public sealed class BSCharacter : BSPhysObject // Add special movement force to allow avatars to walk up stepped surfaces. moveForce += WalkUpStairs();
