Can you give us more information like what happens once you press “space”? Does bullet spawn? Do you have collision check implemented on bullet and player? Is it possible that bullets are colliding with player?

thanks to add_child the bullet is added to the scene, but because the player is rigidbody2d and the bullet is area2d they cannot collide.

it’s because of the look_at function for some reason. How could it affect this?
