Hi Guys. Thanks to those who made suggestions about what I need for my game. Sadly, I'm still not getting what I need. In short, the balls are enemies which deliberately move towards the ship (player). The idea is for the ship to ram the balls of the square tiles and into space. I want both the ship and balls to bounce against each other so that the ship ideally eventually pushes the balls off the tiled area.
Likewise, if the player gets it wrong the balls can push the player of the tiled area.
How can I achieve this please? Image link below.
