Learn how to program the MOUSE_WHEEL event in Flash Actionscript 3.0 to add a whole new level of interactivity to your projects. We access the delta property to see if the user is scrolling up or down.
Is there a way I can make the wheeled object be in front of the other ones? I have the problem that my object is behind the other ones around it when I wheel in on it and make it bigger... just asking... oO
I got this:
"1120: Access of undefined property event" referring to the "event.delta".
I also tried MouseEvent.delta but to no avail.
I have imported the right events and stuff (everything from display, events and ui) so that can't be the problem.
Wow, I should have proof read /doh.
I meant I have a button that I want people to be able to scroll (with the mouse wheel since it's a nob (potentiometer) and have it make my child movie clip play 1 frame per mouse wheel event. I'll check in the help section again but so far so, lost ;)
Great vid, thanks for sharing. I need to do something like this but not zooming. I need have a circle and outside of it there's a movie clip that I want to rotate one frame of it's movie clip per mouse wheel. The movie clip is called arrow, so I imaging it would be something like gotoAndStop("NextFrame"); for + and PrevFrame for - but not sure how to write that. I'm not new to Flash, but am very new to AS3. Any help would be greatly appreciated but either way, thanks again. I Learned a lot.
But the addEventListener is added to the stage.
a.k.a stage.addEventListener in this case.
How is it that event.target is the circles ? I know it works...but why ?

Sorry some how it didn't worked for me like video shows , I got it working replacing redball with "this.redball" but I used this next code, since it worked for me for any object
You can also increase with a negative number, so the object would shrink. This way you dont need to type an if...else... statment. Example :
this.width += zoomAmount * deltaVar;
I did like you said in the video but for some reason it's not working for me.
I do have Flash CS3 & the ActionScript 3.0 but I don't know what went wrong. :(
So, I don't know if I'm missing something or that I need to try something else.
