Moving in circles
|
If you want to move around a 2D planet while still being able to loop around, you have a few options. You could have the ground be flat like any other 2D game and loop one edge to the other, having your characters move just like any other 2D game. Or you could make the ground an actual circle and make your characters orbit around it using basic trigonometrics. We (or, well, I) decided to do the latter.  |
