Platformer/ Side-Scroller Issues

programming
1

Ok, I’ve been working on this game for months now…well, just started working on it after months…Most things are working…

I am having problems with the collisions section dealing with the screen still moving slightly off track when I hit a wall.

My enemy doesn’t seem to fall, kinda floats (doesn’t start ON platform). Enemy doesn’t jump up to platform when reaching a wall.

Both characters get wider the moment they start walking.

…and anything else you notice wrong with the coding…here it is


stop();
_global.attack = false;

var g:Number = .3;
var f:Number = .5;
miscar._x = 120;
miscar.vx = 0;
miscar.vy = 0;
miscar.power = 5;
miscar.jump = -10;
miscar.jumping = false;
miscar.health = 50;
enemy.vx = 0;
enemy.vy = 0;
enemy.power = .5;
enemy.jump = -10;
enemy.jumping = false;
//for (i=1;i<=10;i++){
//_root["wall"+i]._visible=false
//_root["platform"+i]._visible=false
//}
this.onEnterFrame = function() {
	brain(enemy,miscar);
	miscar.vx *= f;
	miscar.vy += g;
	miscar._y += miscar.vy;
	healthbar.gotoAndStop(miscar.health);
	if (miscar.health<=0) {
		cleanup();
	}
	if (miscar._x>=(Stage.width/2)-10 && miscar._x<=(Stage.width/2)+10) {
		for (i=1; i<=10; i++) {
