Circular Movement

[Silverthorn]

nah, that'd create some sort of rectangular/diamond shape (disregarding any deceleration caused by the switch from dvx: 1 to -1). You probably rather need some careful adjusting that depends on where the object is currently located. I felt so free to kind of illustrate it (wasn't quite sure how to name the x-axis; "location" would probably fit better):



Basically, you'll need to adjust hit_j depending on where you currently are. The further to the left/right you are, the greater the variation of hit_j.

Depending on the size & smoothness of the circle, you'll need accordingly many frames. My guess is that drawing such a circle at different resolutions helps in defining these values necessary.
