Displaying images mid-game
Posted: Fri Oct 12, 2012 2:53 pm
It seems like you can only start and end the game with cinematics. So if you want to do things like display a level heading as someone enters the level, or have 2D art displayed on screen, it seems like a different trick is needed.
My thought on this was to use the ability of the game to render a 'screenEffect' for certain spell effects. For instance, the full-screen flames you see when you're hit with a fireburst. So the idea is to make a new particle system for a screenEffect that would display text, and attach it to a spell effect that can produce a screenEffect (preferably without causing damage, but that can be gotten around using disable tricks or an OnDamage hook).
Here screen1.tga (screen1.dds) is a texture I've defined to display some text headings.
So far so good, I've managed to render the custom screenEffect. The problem is, it always seems to occur at a random angle. This is true regardless of what I set sprayAngle to. Any idea how to pin down the angle and make it fixed, or is this a dead end?
