parabolic motion

[Craig Murray]

What would be a clean and flexible solution to generate parabolic or other non-linear motion? My first thought is to tween the x and y seporatly and use speedups and slowdowns but that seems like a lame solution.

 

I'm sure this has come up before and I suspect TweenLite/Max has a clean solution for this, I'm just not finding any examples of it yet.

Hi Craig,

 

For non-linear motion have a look at the bezier and bezierThrough plugins in the plugin explorer.

For non-linear stuff, you could also check out the motion path stuff in the com.greensock.motionPaths package. It isn't for curves yet, but if you wanted to do lines, circles, rectangles, etc. you could do it. For example: http://www.greensock.com/as/docs/tween/ ... ath2D.html

 

You could also consider a CirclePath2D that's squished a bit in one direction (width/height/scaleX/scaleY, whatever) and just use part of it (like tween from progress 0 to 0.5). Just a few ideas.
