How do functions work?

Im just learning how to use functions properly but i kinda got no were.
To me this script look fine but obviuosly not because it dont work.
Can any one give me some insight on why?

Code:

---

onClipEvent (enterFrame) {
        r = function () {
                if (this._rotation != 90) {
                        this._rotation += 5;
                }
        };
}
on (release) {
        r;
}

i don't have flash on this computer so i have no idea if this will work, never seen that done before. Hmmmm

maybe it's the calling of the function which is wrong.
you have:
on(release){
r
}
try this:
on(release){
r()
}

you could also try declaring the function differently, like:
"function r(){}" rather than "r = function(){}"

my impression of a function is that it can be run as long as it is continuously being called. Chuck a trace command in their to see if the function is actually being called.

I will try that, is there another way of doing why i am trying?

I tryed it and it did exacly the same thing as
on(release){
if (this._rotation != 90) {
this._rotation += 5;
}
};
And that only rotated 5 degree. I would like i loop that function. Any ideas

First of all, it's probably not a good idea to keep registering the function r inside an onEnterFrame event. Put it in an onLoad event if need be so it's only made once.

Second, you are calling this inner function in an onRelease event, so it will only be called when you release the key/button/mouse ( whatever release is for, can't remember. )

So, if you want r() to be called every frame ( continuously ) then it needs to be called in an onEnterFrame event.

Hope that helped.

Yea i understand, but i want the function to run after i release my MC. My code only runs the function for 1 frame but it would usealy last about 30.

So what i need.
On release of my MC
run r function untill its complete.

Code:

---

on (release) {
        this.onEnterFrame = function () {
                if (this._rotation != 90) {
                        this._rotation += 5;
                }
        }
}

---

That's how I'd do it, but then you probably want it to stop eventually so you can use "delete this.onEnterFrame;" wherever you want it to stop.

Thanks for that.

code:

---

//	define function

function r():Void {

	if (this._rotation != 90) {

		this._rotation += 5;

	}

}



//	define event

<btn name>.onRelease = function():Void {

	r();

}
