Examples

VBScript Example

set oRoot = Application.ActiveProject.ActiveScene.Root  
set oCube = oRoot.AddGeometry("Cube","MeshSurface")  
oCube.Kinematics.Global.Parameters("posy").value = 4.0  
oCube.Kinematics.Global.Parameters("posx").value = 2.0  
oCube.Kinematics.Global.Parameters("rotx").value = 30  
set oTrans = oCube.Kinematics.Local.Transform  
set oPos = XSIMath.CreateVector3( 1.0, 1.0, 1.0)  
set oObjectPos = XSIMath.MapWorldPositionToObjectSpace(oTrans, oPos)  
Application.LogMessage "The position (1,1,1) is (" & oObjectPos.X & "," & oObjectPos.Y & "," & oObjectPos.Z & ") in the cube object space"  
set mynull = oCube.AddPrimitive("Null")
mynull.Kinematics.local.Parameters("posx").value = oObjectPos.x  
mynull.Kinematics.local.Parameters("posy").value = oObjectPos.y  
mynull.Kinematics.local.Parameters("posz").value = oObjectPos.z
