_IrrBillBoardForceUpdate($h_BillboardGroup)

 

Parameters

$h_BillboardGroup

Handle to the Billboard Group as returned by _IrrAddBillBoardGroupToScene

 

Return Value

Success: True
Failure: False

 

Remarks

Unlike regular billboards the billboard group does not always update the orientation of the billboards every frame.
If you are a long distance away from the billboard group the camera needs to travel a significant distance before the
angle has changed enough to warrent an update of all of the billboards verticies to make them point to the camera once more.
You may want to force a refresh at some point with this call.
