MC animation forwards and backwards

[vimcoweb]

I'm fairly new to actionscripting, but I just can't get a handle on this particular application.

I have a main MC which targets another MC within the main. The targeted MC has a 40 frame shape tween in it. I want to control the shape tween with three buttons on the main MC (up, stop, down). I need to record the position (current frame) of the targeted MC. Please help an actionscripting initiate.

Howdy,

It's quite easy to do. Make an instance of the MC and use this sort of action when the user presses the buttons:

Stop:
on (release) {
tellTarget (instance) {
stop ();
}
}

Down:
on (release) {
tellTarget (instance) {
prevFrame ();
}
}

Up:
on (release) {
tellTarget (instance) {
nextFrame ();
}
}

As you can see you don't need to know the currentframe, but if you do want to know it, you can get it by using this command:

instance._currentframe

That's all

I hope this will help you out,

The code Luke posted will work but I believe it will only display one more frame when going backwards. To get a constant and controlled motion you'll have to create a simple loop that tells the MC to continue playing the previous frame as long as a condition is true....check this out http://www.blutimus.com/bgproject/history.html its an example of how to play a tween backwards and control where it stops as well as whether it plays backwards or forwards and can easily be modified for different conditions....let me know if it suits your needs and I'll give you the code

Thanks Lucky Luke...I got the MC working with the prev and next commands...It operates like a momentary switch right now. I need it to work with a loop so it will continuously go up or down until stopped or reach the end of the MC. Have any ideas...

Blutimus that site is similar to what I want to accomplish, but how can I view the FLASH source code...It looks really good.

thanks guys

Howdy,

It will be quite more complicated if you need to use the loop, because you'll have to add a time delay between the actions, else the movie will playback to fast. I think I could make the .fla file for this effect, if you want to, I'll make it, just give me your email address. I'll have to take a closer look at it by making it myself

Anyways, good luck with your movie,

PS I just came through the tutorial section and I got this tutorial, you might wanna look it out:

but I caution you! I had to change the contents since all the designs in the original were a clients and I replaced them with some really hideous pix of me! So be careful, lol! I think you'll see it's not really that complicated. If you need any explanation, contact me.
