@JonB Thanks the solution was simple, I just didn't see it, @ccc yeah one big bad boss is enough
But now He needs some cool firepower. Will update you when he is ready for a fight

Ok so now the fps is fixed and the boss is just one big UFO.
But now I have a new problem(No suprise there) When the boss appears he fires one laser shot,
but no more. What I'm trying to do is to make him fire lasers all the time (after all he is the boss) but I cant call such a function from update() since the boss is a class and not in the gamefield,
My question: Is there a way in update() to point to spawn:boss() function (or is there a way inside the that function to create something that update all the time)
Sorry for the long post, basically: how do my boss keep firing until he is removed from scene?

@Bjucha You could make the boss a property of your scene (i.e. set self.boss = ... when you spawn it). That way, the boss could have a last_shot_time property, you check that in update, and if it's bigger than, say, 1 second, you set last_shot_time to the current time, and fire a shot.

@omz hmm I really sorry but I don't really understand. what do you mean with property of my scene? and shall that property be inside the spawn_boss()
function? or in the gamefield?

def spawn_boss(self):
    self.boss = Boss(parent=self, position = (100, 600))

Haven't been able to get it to work yet, but Im currently trying a different approach that could work.

I realize this is a few weeks old, but had a few thoughts.

I typically add scene objects of a shared type to a list and then iterate over a method of their class in update.

So at the end up the enemy class init I would add 'enemies.append(self)' and then in the scene update method add 'for enemy in enemies': enemy.cooldown() or something to that to that effect.

Obviously, you'd have to write a bit more AI methods for the enemy ships, so you'd probably want to subclass them to save space.

Thanks for the tip. I did get it to work by using

counter = 10 
		while counter != 0:
			Action.wait(2)
			self.items.append(boss)
			bossfires = SpriteNode('spc:BoltBronze', parent=self)
			bossfires.position = boss.position + (-50, 30)
			bossfires.z_position = -1
			b = random.uniform(10.0, 2500)
			actions = [A.move_to(b, 100, 2 * 2), A.remove()]
																
			bossfires.run_action(A.sequence(actions))
			self.bossfires.append(bossfires)
			Action.wait(2)
			counter = counter - 1```

This works but is not really "perfect" for me. But will look at what you suggested and see if I can use it.
