Help Coding Rapid Fire

[Avickahn]

Godot v4.3

So I’m making a side scrolling shoot 'em up. I was able to make code for firing that works really well, but the problem is, it only fires each time the button is pressed. As a result, one would have to rapidly press the fire button to shoot lots of times in a row. I’m wondering what would be the easiest way to allow the player to hold the fire button to fire a continuous stream of projectiles.

The code I have for shooting is as follows, with this simply being the basic attack without any weapon upgrades:

	if Input.is_action_just_pressed("action_shoot") and akane_upgrade == 0:
		var new_proj1 = proj1.instantiate()
		new_proj1.global_position = $Main_Gun.global_position
		add_sibling(new_proj1)

Any suggestions for the best way to do so?

In _process(delta) function:
if Input.is_action_pressed(“fire”):

Connect “Input.is_action_pressed” signal and place in _process. It should execute each tick allowing continuous fire as long as the action button of choice is being pressed. Just plop your firing code below the is action pressed signal.

one solution is to use a timer

var gun_is_cooked :bool = false
if Input.is_action_just_pressed("action_shoot") and akane_upgrade == 0:
		$Timer.start()
		while !gun_is_cooked:
				# stuff

func _on_timer_finished():
		gun_is_cooked = true

Yeah a timer sounds good, but don’t use a while loop.

func _unhandled_input(event: InputEvent) -> void:
	if event.is_action("action_shoot"):
		if event.is_pressed():
			$Timer.start()
			# uncomment below to also shoot every press
			#_on_timer_timeout()
		elif event.is_released():
			$Timer.stop()


func _on_timer_timeout() -> void:
	# your shoot code
	var new_proj1 = proj1.instantiate()
	new_proj1.global_position = $Main_Gun.global_position
	add_sibling(new_proj1)

So I tried your idea, and it works. However, is there a way to space out how frequently it’s fired with your method? Because right now it fires as a continuous stream.

[TheAncientOne]

I would imagine a timer in a global var or other, could set a timer to fire off and only fire every x tick instead of every tick.

So, by combining your method with @TheAncientOne 's method, I was able to get it working! Tysm, everyone!
