The cannon needs to remain stationary. And just fires the projectile at the character who has to jump over the projectile.
The turret behavior can do that.
Alright. So what properties/behaviors am i suppose to give my projectile?
The projectile? Whatever you want to achieve? Collision events can trigger anything from a loss of life on a life bar to a game over - it would depend on your game.
Alright. I well i didn't know rather or not you needed to make your own projectile or not. I assumed so.
