From b552e8ebe3644b4f1777de6c4c4ea36a6671bc16 Mon Sep 17 00:00:00 2001 From: Charles Krinke Date: Sun, 26 Oct 2008 17:09:26 +0000 Subject: Thank you kindly, Idb for a patch that solves: llGetBoundingBox is completely unimplemented. The attached patch contains a partial implementation for single prim objects and standing, flying and ground sitting avatars. In the case of an avatar sat on an object or multi-prim objects only the bounding box of the root prim is returned. llRezObject and llRezAtRoot ignored any velocity parameter. The attached patch makes use of it if it is not a zero vector. --- .../Shared/Api/Implementation/LSL_Api.cs | 105 +++++++++++++++++---- 1 file changed, 89 insertions(+), 16 deletions(-) (limited to 'OpenSim/Region/ScriptEngine') diff --git a/OpenSim/Region/ScriptEngine/Shared/Api/Implementation/LSL_Api.cs b/OpenSim/Region/ScriptEngine/Shared/Api/Implementation/LSL_Api.cs index 8aeca31..b0a99f3 100644 --- a/OpenSim/Region/ScriptEngine/Shared/Api/Implementation/LSL_Api.cs +++ b/OpenSim/Region/ScriptEngine/Shared/Api/Implementation/LSL_Api.cs @@ -2412,8 +2412,12 @@ namespace OpenSim.Region.ScriptEngine.Shared.Api float groupmass = new_group.GetMass(); - //Recoil. - llApplyImpulse(new LSL_Vector(llvel.X * groupmass, llvel.Y * groupmass, llvel.Z * groupmass), 0); + if (new_group.RootPart.PhysActor != null && new_group.RootPart.PhysActor.IsPhysical && llvel != Vector3.Zero) + { + new_group.RootPart.ApplyImpulse(llvel, false); + //Recoil. + llApplyImpulse(new LSL_Vector(llvel.X * groupmass, llvel.Y * groupmass, llvel.Z * groupmass), 0); + } // Variable script delay?
