Well, I actually have two things. First, I have an easy method for a jumping system in a flash game. It’s a bit glitchy, but here it is:

```auto

onClipEvent(load) {
       var fallness = 10; } 
onClipEvent(enterFrame){           
       if (!this.hitTest(_root.ground) && !Key.isDown(Key.UP)) {  
             this._y += fallness; 
        } 
         if (Key.isDown(Key.UP)) {
	gravity -= 1;
	this._y -= gravity;
        }
        if (this.hitTest(_root.ground)) {
	gravity = 10; 
          } 
} 
onClipEvent (keyUp) {
       gravity = 10;
}

```

ok so there you can apply your own crap to it. And I have another thing to ask: how would you go by using a switch statement. ive been having trouble with them along with for… in loops

I’m not sure what your first question is, but you can find some information about the second here: [http://www.kirupa.com/developer/actionscript/as\_tricks.htm](http://www.kirupa.com/developer/actionscript/as_tricks.htm)

Same here with the first question but with the second you could use something like:

myVar = Key.getCode();

Then use myVar in a switch statement:

[AS]  
switch(myVar) {  
case (37):  
do some stuff;  
break;  
case (39):  
do some other stuff;  
break;  
default:  
do some default stuff;  
break;  
}  
[/AS]

You can look up the numbers in the Flash reference for the key codes. Also check out Best of Senocular for excellent explanation of switch/case by clicking
