I can't get scrolling to work at all with this change (with wheelEnable:true, and the now-default wheelScale:120) testing on latest voxelmetaverse, for unknown reasons. Even when pointer lock is acquired, scrolling the mouse does not change the inventory slots. If I remove the added "if @game.shell.pointerLock" line then scrolling works.

@deathcap I removed the first whitespace, cant seem to remove the second (im using githubs edit button) as it seems to be added automatically...
