    It's friction which causes bigger objects to fall slower then smaller objects, but faking it like mass*gravity does do the trick nicely. Just pointing out it isn't true to physics.

    Ah, right on.

    Still having troubles with this if anyone has any insight.

    Thanks for the help so far, everyone.

    I see that there's a function to calculate the length of the vector, but when do you actually update the length of the distance vector? As far as I can tell you only update the x and y components but not the length.

    The length is a getter property, and the length is calculated only when you get it.

    Yeah this is correct. The length is being calculated and updated properly, from what I can see. Otherwise my projections wouldn't be working, I think.

    Something with my reaction code is wrong.

    Maybe the solution eludes you because the red ball should be ROTATING along the edge of the bigger one when it makes contact with it. ?
