    Loop-based animation

    Posted by Ryan Hill on November 10, 2005 at 6:16 pm

    I don’t have a lot of animation experience, but I’ve done a lot of video game physics. What this means is that I’m used to applying physics in terms of:
    NewX = PrevFrameX + VelocityX

    There’s lots of things that can be done easily with this that look nearly impossible to do with expressions, because they need to be more in the form:
    X = StartingX + VelocityX * Time

    So if I have Velocity change over time, this gets very complex very quickly.

    I think maybe Motion Math is what I’m looking for, but I haven’t found a tutorial that really explains it, instead of just going, “Take this code and copy and paste it into Motion Math.” Any suggestions?

    I wouldn’t spend any time learning Motion Math because it’s been removed from AE in newer versions. Anything that you would absolutely need Motion Math for you can do with a combination of expressions and scripting. The best resource for scripting is the AE Scripting Guide pdf. It’s a pretty steep learning curve until you get familiar with AE’s object hierarchy, but it’s worth the trouble.
