im currently working on a project that needs to disable input key in the InputMap when said key becomes false; but i don’t know how to do can someone help me.
here’s my code if you need.
extends KinematicBody2D
export var motion_speed = 300
var ray
var aim = preload("res://Scenes/Entities/Player_Extensions/Aiming_Reticle.tscn")
export (bool) var is_aiming = false
onready var r = get_node("Aiming_Reticle")
func _ready():
set_fixed_process(true)
set_process_input(true)
ray = get_node("Ray")
func _fixed_process(delta):
var motion = Vector2()
if Input.is_action_pressed("ui_up"):
motion += Vector2(0, -1)
ray.set_rotd(180)
if Input.is_action_pressed("ui_down"):
motion += Vector2(0, 1)
ray.set_rotd(0)
if Input.is_action_pressed("ui_left"):
motion += Vector2(-1, 0)
ray.set_rotd(-90)
if Input.is_action_pressed("ui_right"):
motion += Vector2(1, 0)
ray.set_rotd(90)
motion = motion.normalized()*motion_speed*delta
move(motion)
func _input(event):
var s = aim.instance()
if event.is_action_pressed("ui_event 1"):
is_aiming = true
add_child(s)
s.set_pos(Vector2(0, -64))
placed()
if event.is_action_released("ui_event 1"):
is_aiming = false
r.queue_free()
placed()
func placed():
if is_aiming == false:
print("FALSE!!!!!")
if is_aiming == true:
print("TRUE!!!!!!")
In func input(event): I made it so if event.is_action_pressed(ui event 1): would spawn in a aiming reticle, it also make a (bool) variable called is_aiming = true. I also have a if statement called if event.is_action_released(ui event 1): that despawns the aiming reticle and also makes is_aiming = false. I have it so that you can spawn four aiming reticle using the 8, 5, 6, 4 and despawn upon releasing those keys. Having multiple aiming reticles seems to not work saying that it attempt to call queue_free in base null instance on a null instance so what i want is to make it so while i pressed one of the keys make it so i can’t spawn another from the other keys.

I actually misread your question, and have since hidden my comment. Sorry. Let me get back to you.
Edit:
So the aiming reticle is meant to be visible as long as you’re holding either 8, 5, 6, or 4.
You have the reticle node r as an onready variable, so it’d already be a child of the scene. Meanwhile, when event.is_action_pressed("ui_event 1") is true you add a node s to the scene. Did you perhaps mean r - which would be redundant since r is already be a child - or is this a different node entirely? Finally, when event.is_action_released("ui_event 1") is true you delete r; that’s what queue_free is for. Referencing r after that would get you null.
If all you want to do is show and hide the reticle the methods show() and hide() would be more appropriate.
