Next we need the PostRender() function, which is responsible for caching the
value of our variables, and is part of the main draw loop.
/**********************************************************
* Caches values for variables. Also the main draw loop
**********************************************************/
event PostRender()
{
Super.PostRender();
/** Sets the pawn owner */
PawnOwner = Pawn(PlayerOwner.ViewTarget);
if ( PawnOwner == None )
{
PawnOwner = PlayerOwner.Pawn;
}
TutPawnOwner = TutorialPawn(PawnOwner);
if (TutPawnOwner != None)
{
/** Sets the size of the screen based on resolution*/
ResScaleX = Canvas.ClipX/1024;
ResScaleY = Canvas.ClipY/768;
}
}
We won't use PostRender as heavily as Unreal Tournament does, but it is important
to understand that it's essential for using Scaleform as it allows for additional things
to be drawn on screen, including animated crosshairs and overlays that mobile
devices, such as iOS, require.
