When I use a create overlay function, what is the default overlay id if I type something like:
CreateGraphicOverlay(100,100,300,1);
Is it automaticly set to 1 or based on the number of overlays currently on the screen?
Or does it have to be specified by typing something like:
over1=CreateTextOverlay (50,80,120,2,15,"This is a text overlay");
Always use it like this:
int overlay_id = CreateGraphicOverlay(100,100,300,1);
You cannot predict what the ID might be.
