Action Script to Move Objects 1

[vivasuzi]

Is there a way to write an action script to move an object? I need to move an object along a path that is created mathematically. For example, my graphic has to move along a sin wave line. The sin wave is calculated in code.

Is this even possible? I'm very new (just started today) to action scripts and I don't want to waste time if this isn't possible.

Thanx for any help!

Yes it is posible using a movie clips '_x' and '_y' Regards

How's this?

Here's the code, it's simply attached to the "ball" which is a movieclip.

onClipEvent (load) {
count = 0;
}
onClipEvent (enterFrame) {
//horizontal position
_x = count;
//vertical position (degrees turned to radians for calculation, the rest is just centring the wave on the stage)
_y = (Math.sin(count*Math.PI/180)*100)+180;
//go to the next position
count++;
//reset once 360 degrees have been traversed
if (count>359) {
count = 0;
}
} Slainte

I clicked the link and the pop up window just sits there loading.. after it gets to 50% it seems to freeze. If it does work it's very slow. *Suzanne*

I'm using Windows 2000 on a compaq. But it might be b/c I'm at work. I'll wait til I get home and try it out. *Suzanne*
