I’m making a shoot em’ up game and I wanted to be able to have only 2 bullets on screen at a time.
Could someone help me with it?
Info: The bullets are created by the player node as an instance of the bullet’s scene.

there are many ways to archive this. One way is to use groups.

put your bullet in the bullet group, then do something like this

func shoot():
    if get_tree().get_nodes_in_group("bullets").size() < 2:
      #instaciate bullet here
      #dont forget to put them in the bullet group
      #there are allready 2 bullets on the way, no bullet gets spawned
