Functions

Type	Name
void	VRAddCallbackActivate(HNode node, EventTwoNodesUserFunc callback, void * userData, int flags) Event callbacks. Some already exist : VRAddCallbackUpdate for Event::TimeStep VRAddCallbackNodeCreation for Event::Create VRAddCallbackNodeDestruction for Event::Delete VRAddCallbackNodeRenamed for Event::Rename.
void	VRAddCallbackBreak(HNode node, EventTwoNodesFunc callback, void * userData, int flags) Add Break callback (assembly has ceased colliding)
void	VRAddCallbackClick(HNode node, EventNodeFunc callback, void * userData, int flags) Add Click callback (button or similar node clicked)
