Hey GUys,

Been practicing actionscript etc.  
Came across this game tutorial and saw the following code:

function moveStuff() {  
if (Key.isDown(Key.LEFT)) {  
this.\_x -= 5;  
}

box\_mc.onEnterFrame = moveStuff;

For some reason i thought, when you call a function you have to end it with curly brackets. ie. moveStuff();

How come this isnt the case??

Thanks  
🙂
