Hello all,

How can I move sprite (black circle) **forward** with specific Velocity depend on side from which I touches sprite by another sprite (red circle with white arrow)?

Examples (red arrow indicates path which black ball moves on):

I use Arcade Physics.

Just use circular bodies and velocity. You don’t need to do anything else.

I’ve solved it by change physics to MatterJS and using this solution to calc velocity between 2 points: [Is it possible to use 'sprite move to another sprite' on Matter.js?](https://phaser.discourse.group/t/is-it-possible-to-use-sprite-move-to-another-sprite-on-matter-js/2367).
