# Thread: A Line In AS2 Is Freezing The Game

1. ## A Line In AS2 Is Freezing The Game

I started to work on a new code (last one was for a fighting game but as the guy never finished them, I can't do anything else atm) that does work---but it freezes the game, why? Here's the code.

stop();
xSpeed = 0;
maxSpeed = 20;
maxSpeed2 = -20;
slowSpeed = 1;
var grav:Number = 0;
var gravity:Number = 10;
var maxJump:Number = -9;
var toughingGround:Boolean = false;
Son.onEnterFrame = function() {
this._x += xSpeed;
//gravity
Son._y += grav;
grav += gravity;
while (ground.hitTest(Son._x, Son._y, true)) {
}
if (ground.hitTest(Son._x, Son._y+5, true)) {
toughingGround = true;
jumping = false;
} else {
toughingGround = false;
}
if (Key.isDown(Key.SPACE) && toughingGround) {
jumping = true;
grav-maxJump;
} else if (Key.isDown(Key.RIGHT)) {
this._xscale = 100;
if (xSpeed>10) {
this.gotoAndStop("SonRun");
} else {
this.gotoAndStop("SonWalk");
}
if (xSpeed<maxSpeed) {
xSpeed += 1;
}
} else if (Key.isDown(Key.LEFT)) {
this._xscale = -100;
if (xSpeed<-10) {
this.gotoAndStop("SonRun");
} else {
this.gotoAndStop("SonWalk");
}
if (xSpeed>maxSpeed2) {
xSpeed -= 1;
}
} else if (xSpeed>0) {
this.gotoAndStop("SonBreak");
xSpeed -= slowSpeed;
} else if (xSpeed<0) {
this.gotoAndStop("SonBreak");
xSpeed += slowSpeed;
}
};
So what's freezing the game? The line

while (ground.hitTest(Son._x, Son._y, true)) {
is causing it to freeze up. I tested it and when I change the word "while" to "if" Sonic falls off screen, but the game no longer freezes. I spent over an hour with an friend to try and fix this and I even messaged the guy who made the tut videos (still awaiting a reply), but so far no luck is fixing this.

Can anyone tell me how to fix this? I really hate AS, I do, but it is what it is. I can't fix it so asking for help. If get a reply back from the guy I'll post here saying so.

AND BEFORE YOU ASK! No, his fla files are a unexpected format so flash 8 can't open them.

2. what about the fla that you use to work on, not need other fla.
you not like AS becose you not know it well, simple as.

That was for a fighting game, the guy stopped before showing how to do AI movement and such. This code is for a Sonic game, I didn't give up on the other code it's just there's nothing more to do with it atm until the guy posts another part or I find an AI script, which the Sonic tuts above will get into later as I checked ahead of time.

I'll try it, I'll edit in whether or not it works (flash takes like a full min to open)

EDIT:Well the game doesn't freeze but Sonic falls off screen, gonna mess around a bit but I'll look back to see if you posted anything else.

4. OK I edited it to

while (ground.hitTest(Son._x, Son._y, true) && grav-->0) {

and Sonic does touch the ground, but he won't stop bouncing up and down. At least we're getting somewhere.

EDIT:With the var count do I add it increasing and decreasing wherever the grav/gravity does?

5. change

while (ground.hitTest(Son._x, Son._y, true)) {

to

var count = 10;
while (ground.hitTest(Son._x, Son._y, true) && (count-->0)) {
