I would like to rotate an object, plane or thin box, like a door opening.
When i use RotateObjectGlobalY(objno,angle# ) it rotates about its centre so clearly i need to somehow rotate about an offset so it rotates about its edge.

I suppose i could make the object twice the size and have half transparent but as a last resort.

Any pointers?

initially, Move your door on X axis like this : newX = currentX + DoorWidth/2 (With Global commands) to have the pivot in X=0 then apply the FixObjectPivot(objID) command to it, and then, try to rotate it ? (never used it but ... it should work)

Hi Mike, spot on, just what i needed. I have played with the example and it does exactly what i want.

I still use the online F1 help file which annoyingly still doesn't show examples but still i might not have found this, so a big thanks.
