For loop for instancig / logic?

hoppala

im instancing enemies at scene with a for loop. But i need to make some changes. Coudnt figure out the logic. The thing is,

there will be, max_can_instance On_scene_instanced

example func max_can_instance= 20. Means this func can only instance Total of 20 enemy, but, On_scene_instanced=10 at most 10 of them can be at the scene.

When an enemy died then another one will be instanced, till the total instanced number reach the 20.

When Total instanced enemy reach the 20, function will stop instancing. Thanks.

The loop should be a function that takes a parameter, which is the amount of objects to create. You control what you pass in, and then at the start of the function check the numbers to make sure that there are not more than you want. You can use get_nodes_in_group() to find the number of enemies that are alive in the scene.

thanks for the tip, i handdle it

    func level_1_wave_1(instance):
    		for i in range(instance):
    			do instance stuff

and call this function from another script

func _process(delta):
	if can_level_1_wave_1_go == true:
		if get_tree().get_nodes_in_group("enemy_1").size() < 10:
				wave_script_call.level_1_wave_1(1)
				level_1_wave_1_counter += 1
		if level_1_wave_1_counter == 20:
			can_level_1_wave_1_go = false

it works fine but at the same time it scares me. Because i have around 60 level planned in my mind, and every lvl have at least 3 wave of enemy attack, some time more. and i need the organizethis wall of code, just thinking about it give me a headache. just think about it, what if i need the edit whole wave number etc. :# =) :s

Put all then numbers in a Dictionary and then do it dynamically. You almost never want to have hard-coded values anywhere in your code.

Can you give a example if you have a time please. i didnt use dictionary concept before??

The easiest way IMO to understand a dictionary is to think of it has a key to data pairing. Godot dictionaries don't work that much differently than in any other language so brushing up on the concept in any language will help.

It gives you a headache is good; programming is all about writing the code the best way early on. If your logic is leading you toward a "code wall" then you're heading in the wrong direction.
