From 1d65b0d80296a672c8023293aee7d0a01bad4066 Mon Sep 17 00:00:00 2001 From: Robert Adams Date: Thu, 18 Jul 2013 19:09:55 -0700 Subject: [PATCH] BulletSim: add position resetting for stationary avatars so they don't move around when standing on a stationary object. Create proper linkage between BSCharacter and its actor by generating a UpdatedProperties event the same way BSPrim does. --- .../Physics/BulletSPlugin/BSActorAvatarMove.cs | 17 ++++++++++++++++- .../Region/Physics/BulletSPlugin/BSCharacter.cs | 8 ++++---- 2 files changed, 20 insertions(+), 5 deletions(-) diff --git a/OpenSim/Region/Physics/BulletSPlugin/BSActorAvatarMove.cs b/OpenSim/Region/Physics/BulletSPlugin/BSActorAvatarMove.cs index 928b350645..0f11c4a158 100755 --- a/OpenSim/Region/Physics/BulletSPlugin/BSActorAvatarMove.cs +++ b/OpenSim/Region/Physics/BulletSPlugin/BSActorAvatarMove.cs @@ -130,6 +130,7 @@ public class BSActorAvatarMove : BSActor SetVelocityAndTarget(m_controllingPrim.RawVelocity, m_controllingPrim.TargetVelocity, true /* inTaintTime */); m_physicsScene.BeforeStep += Mover; + m_controllingPrim.OnPreUpdateProperty += Process_OnPreUpdateProperty; m_walkingUpStairs = 0; } @@ -139,6 +140,7 @@ public class BSActorAvatarMove : BSActor { if (m_velocityMotor != null) { + m_controllingPrim.OnPreUpdateProperty -= Process_OnPreUpdateProperty; m_physicsScene.BeforeStep -= Mover; m_velocityMotor = null; } @@ -197,7 +199,7 @@ public class BSActorAvatarMove : BSActor { if (m_controllingPrim.Flying) { - // Flying and not collising and velocity nearly zero. + // Flying and not colliding and velocity nearly zero. m_controllingPrim.ZeroMotion(true /* inTaintTime */); } } @@ -266,6 +268,19 @@ public class BSActorAvatarMove : BSActor } } + // Called just as the property update is received from the physics engine. + // Do any mode necessary for avatar movement. + private void Process_OnPreUpdateProperty(ref EntityProperties entprop) + { + // Don't change position if standing on a stationary object. + if (m_controllingPrim.IsStationary) + { + entprop.Position = m_controllingPrim.RawPosition; + m_physicsScene.PE.SetTranslation(m_controllingPrim.PhysBody, entprop.Position, entprop.Rotation); + } + + } + // Decide if the character is colliding with a low object and compute a force to pop the // avatar up so it can walk up and over the low objects. private OMV.Vector3 WalkUpStairs() diff --git a/OpenSim/Region/Physics/BulletSPlugin/BSCharacter.cs b/OpenSim/Region/Physics/BulletSPlugin/BSCharacter.cs index c9e3ca0ead..59e7f5ffbe 100644 --- a/OpenSim/Region/Physics/BulletSPlugin/BSCharacter.cs +++ b/OpenSim/Region/Physics/BulletSPlugin/BSCharacter.cs @@ -709,10 +709,10 @@ public sealed class BSCharacter : BSPhysObject // the world that things have changed. public override void UpdateProperties(EntityProperties entprop) { - // Don't change position if standing on a stationary object. - if (!IsStationary) - RawPosition = entprop.Position; + // Let anyone (like the actors) modify the updated properties before they are pushed into the object and the simulator. + TriggerPreUpdatePropertyAction(ref entprop); + RawPosition = entprop.Position; RawOrientation = entprop.Rotation; // Smooth velocity.
