This event is triggered every time before GTA renders a new frame.


float timeSlice
  • timeSlice: The interval between this frame and the previous one in milliseconds (delta time).


The source of this event is the client's root element.


This example makes the camera follow the player in a GTA2-like way.

function updateCamera ()
	local x, y, z = getElementPosition ( localPlayer )
	setCameraMatrix ( x, y, z + 50, x, y, z )
addEventHandler ( "onClientPreRender", root, updateCamera )


This event and onClientRender will trigger whatever function it is attached to with every frame. Depending on the server's maximum FPS and what your computer might handle - you might end up triggering the function 30-60 times per second.

As a result, this event may cause severe lag and/or even crashes if not used cautiously.
