Help with "For" statement..

[Blinger1]

Okay, I am an alright Flash user, using Flash 8 (since we only have Flash 7 at school, I thought 8 was okay.)

Anyway, I have a problem with my code. All what is meant to happen is the line spins for 180 degrees only, but it keeps going.. forever!!

Here is my code:

onClipEvent (enterFrame) {
for(i=0; i<1; i++) {
this._rotation ++;
trace(i);
}
}

And here is the SWF (link (http://img410.imageshack.us/my.php?image=gayzie1.swf))

Whats the trace saying?

[Blinger1]

Oh yeah sorry, it just keeps saying "0"

[Protege]

Oh yeah sorry, it just keeps saying "0"

Is the for, for a smooth rotation?
else if not ->

on (release) {
_root.mcobj._rotation += 180;
}

I want it to go slowly the 180 degrees.. (it will soon be a random number)...

I have also tried a while statement, but that went too fast :(

Basically the method your doing is rotating it on each frame enter, so its going to be infinite, so a for loop isn't how your going to do it on a frame enter, give me a few minutes and I'll come up with something.

[Blinger1]

How about,


onClipEvent(load){
for(i=0; i<1; i++) {
this._rotation ++;
trace(i);
}
}


going to try that


edit: didn't work, the trace only says "0" :(

This will work, add it to a button call the movieclip your rotating mcobj



on (release)
{
for ( var i = 0; i <= 180; i++ )
{
inter = setInterval( function () { _root.mcobj._rotation++; clearInterval( inter ); }, 25*i );
}
}

Okay that seemed to make it spin!

Now, how do I make it stop after it reaches 180 degrees?

[Protege]

oo forgot :p


on (release)
{
rotation = 180;
for ( var i = 0; i <= 10; i++ )
{
var inter = setInterval( function () { if ( !rotation == 0 ) { rotation--; _root.mcobj._rotation+=1; clearInterval( inter );}} , 25*i );
}
}

Thank you very much..

+rep, do you go on Habbo?

[Protege]

Occasionally, and no problem ;) Needs a bit more work as it gets faster each time you press the button, I'll look into that later ;)

[Blinger1]

nono, i didn't want it to get faste :P... It was going to be a "you are this cool" meter..

I'll donate you some rares next time i am on if you want :)

[Protege]

Its alright, I'll see how I can make it to stop getting faster ;)

Heres an update, its a easier method to rotate the objects


var objRotate;
var rotation;

function rotateObj ()
{
if ( ! rotation == 0 )
{
_root[objRotate]._rotation += 1;
rotation--;
rotating = true;
}
else
{
rotating = false;
clearInterval( interval );
}
}

function rotateObject ( degree, obj, speed )
{
if ( rotating === true )
{
// fail
}
else
{
rotation = degree;
objRotate = obj;
for ( var i = 0; i <= 180; i++ )
{
clearInterval( interval );
interval = setInterval( rotateObj, speed );
}
}
}

stop();Place that in the actionscript frame (root) and use this func to rotate any movieclip.

On a button :

on (release)
{
rotateObject( 90, "mcobj", -50 );
}In a script...

rotateObject( 90, "mcobj", -50 );
Syntax:
Pink -> Degree
Orange -> Instance name
Green -> Speed

:D Any probs post.

Nice work James!
