So i am making a 2D aircraft fighter game (a game with gameplay like skyforce 2014) and i tried to create a type of bullet that can shoot 10 more smaller bullets in a circle. it worked when i put it alone in the scene. However, when i added that type of bullet to my aircraft. the small bullets that shot from the main bullet do no damage to my aircraft. can your guys give me some advice please ? down here is my setting
