yeah, so i just bought ace combat x for psp on fri (i beat it already :P) and now im feeling all badass about planes, jets, etc. im trying to make a top down jet fighter game, but i need help with 2 things. first, i need an easy, simple (unreg) way to create trails of wind/smoke that come out from behind planes and missles when they go fast, then slowly fade away.

Next, i need some way to have the player's plane stay always at the edges of the screen, never flying in towards the middle. basically so that the player cant see behind them, but can see extra far in front, opposed to being plastered dead center in the view. im pretty sure this can be done somehow, but im too retarded to figure it out. so, can some sympethizers help me out, cause otherwise im gonna give up, mainly cause without the view thing the game will be retarded(though even with it itll still suck, 'cuase im really bad at game maker.) thank youz!
