Getting stunlocked by loops

Fruitdude

Hello, could someone explain to me what my code does here Github? I always have problems understanding loops 100%

I try to achieve the following behaviour with this script:

detecting enemies via a Area2D Node
take two Line2D Nodes and put the first point of BOTH Line2D Nodes at the Muzzle position
put the second point of the FIRST Line2D Node at the FIRST enemy my area detected
put the second point of the SECOND Line2D Node at the SECOND enemy my area detected
So every second point of the Line2D Node should 'connect' with an individual detected enemy and not connect all to the same one.

In the end i want a weapon that behaves like a shotgun but the individual Line2D Nodes should find and enemy and connect with it.

Hi, you flagged your own post here but no reason was given in the flag reason field.

This should work m8. Your code wasn't working because your logic worked like this: for every enemy, go through all the lines an reassign them, meaning you'll end up only seeing the lines being changes for the last enemy. I added if count > 2: count = 2 below for you because it seems as though you only have two lines to work with, so if there were more enemies than lines you'd have a problem.

func _input(event):
	if event.is_action_pressed("shoot"):
		enemies = enemy_detection_area.get_overlapping_areas()
		var lines = $Thunder.get_children()
		var m = $Muzzle
		var count = enemies.size()
		if count > 2: count = 2
		for i in range(count):
			print(enemies[i].global_position)
			lines[i].points[0] = m.position
			lines[i].points[1]  =  to_local(enemies[i].global_position)
