Button help

[bigjimmo]

I'm trying to make a button that when clicked, moves aroung like a dial on a radio. I want it to move 90 degrees when it is first clicked and then another 90 when it is clicked the second time. I have made a Movie clip symbol of the button so that on frame 2 it has rotated 90 and on frame 3 it has rotated another 90.

What action script can I use to make the movie clip go to frame 2 on the first click and frame 3 on the second click. I tried the following:-

on (release){
_root.buttonMC.gotoAndPlay(2);
}
on (release){
_root.buttonMC.gotoAndPlay(3);
}

This obviously didn't work, it just goes to frame 3 but what action script do I use for it to work?

thanks

Hi bigjimmo,

Do u mean something like this?

[bigjimmo]

Yes that is similar to what I want, I couldn't see the action script though as I am using Flash 5.

Could you please post the action script here?

Thanks for your help

Hi Jim,

Make a button and put this on the button

on (press) {
_root.i ++;
}


Then put this button in a MC...
Put this code on the MC

onClipEvent (enterFrame) {
this._rotation = 90*_root.i;
}

:)

I just realized that u might not want it to jump to the next position but go there in a tween like motion? Right?

[bigjimmo]

Thanks alot

Jim:D

Is it ok like this or do u want it to move like a tweened animation...

[bigjimmo]

That is fine the way it is. How complicated is it to add the tween effect?

Jim

[avatar]

For the tweening I would add a function... which can get a little complicated...
But if this is what you where looking for, why make it more difficult? :)

[bigjimmo]

So my button turns around four times (90 degrees). Is it possible so that I can play 4 different Movie clip each time the button is clicked. e.g. changing channels on a T.V.?

[avatar]

Sure...
Do something like this

if (i == 1){
_root.gotoAndPlay("whateverlabel")
} else if (i==2){
_root.gotoAndPlay("whateverlabel2")
}
...

But make sure that if you only have 4 mc you set i back to 0 when it reaches 4

:)

If u were still wondering how to get a tweened effect...

Replace the code on th MC by this one...

onClipEvent (load) {
equiv = 0.3;
// this is the weak part of the code
// 180/angle MUST BE an integer
angle = 90;
}
onClipEvent (enterFrame) {
if (_root.i>=360/angle) {
_root.i = 0;
}
finalRot = angle*_root.i;
if (finalRot>180) {
finalRot -= 360;
dRot = Math.abs(this._rotation)-Math.abs(finalRot);
} else if (finalRot<=0) {
dRot = Math.abs(this._rotation)-Math.abs(finalRot);
} else {
neg = false;
dRot = Math.abs(finalRot)-Math.abs(this._rotation);
}
this._rotation += (dRot*equiv);
if (Math.round(drotation+targ._rotation) == rotation) {
targ._rotation = rotation;
}
}

Thanks for that avatar, you certianly know your action script.

Thanks for your help

OK, i'm nearly there. I've written the following code:-
if (i==1){
_root.channel2MC._visible=false
_root.channel3MC._visible=false
_root.channel4MC._visible=false
}
else if (i==2){
_root.channel1MC._visible=false
_root.channel3MC._visible=false
_root.channel4MC._visible=false
}
else if (i==3){
_root.channel1MC._visible=false
_root.channel2MC._visible=false
_root.channel4MC._visible=false
}
else if (i==4){
_root.channel1MC._visible=false
_root.channel2MC._visible=false
_root.channel3MC._visible=false
}
}

This works fine to start with but for example, if I click twice channel2MC plays, then if I click one more time nothing happens. I don't know what to do to resolve this problem?

Just one last thing, who do I set i back to 0?

thanks for your help,

Jim:D

Can you put that piece of .fla online...
Otherwise it's gonna be hard to help ;)

[Vitaly]

Is that how you want it to rotate? There's not much as though.

[Vitaly]

I just hate how those attachments work. Anyways, you can download the files I attached from here http://vitaly.intervelopers.com/rotatingbutton.swf
http://vitaly.intervelopers.com/rotatingbutton.fla

[bigjimmo]

ok here is the file.

[avatar]

This should do the trick...

[bigjimmo]

I've just looked at the .swf and it works perfectly, thanks alot. One small problem is that i'm using flash 5 and I cannot open the .fla file.

Sorry to be a pain but could send me a flash 5 compatable version or tell me how you did it.

Sorry about the inconvenience.

Cheers
