To add more to the question, I have a Dialogue Box scene and I instantiate it when I speak to NPCs, my question is where and how do I position this Dialogue Box? I tried using getcamerascreen_center() and it was successful to a degree. If I move around the place while the Dialogue Box is open, my guess is that in an effort to keep up with the screen center, the instance jitters like crazy, the same thing happens if I set the position equal to the player.
Basically, is there a function similar to GameMaker's 'Draw GUI' event? Where things drawn in that event are drawn directly to the screen and not to the game, if that makes any sense.
