I am trying to make a game and my aliens are supposed to go to the planet (I have the planet as a circle in the middle of the screen not a sprite on the bottom of the screen) so in the event sheet I added an event (system, every tick) and then added the action "angle toward position" for my alien, typed in planet.x, planet.y, I added event (system, every tick) set the bullet speed to 102.25 for my aliens added event (alien on collision with planet set physics to immovable)I also set the bullet speed to 0 and made sure solid was enabled for the planet and my alien, but when I test it the aliens go through the planet to the center and start spinning. Please any information would be helpful even if you just say whether or not it is a bug.
