ive setup an input variable in project settings to control mouse wheel up or down
however my code doesnt do anything?

if Input.is_action_pressed("mouseUP"):
		weapon_change_number += 1
	if Input.is_action_pressed("mouseDOWN"):
		weapon_change_number -= 1

You might want to put that in _input():

func _input(event):
	if event.is_action_pressed("mouseUP"):
		weapon_change_number += 1
	if event.is_action_pressed("mouseDOWN"):
		weapon_change_number -= 1

    Megalomaniak no not intentional, dont know how to correctly post code on the new forum,

    cybereality what 's the difference if i put it in input? also why do i need to call 'action released' for mouseDOWN?

        Sorry, the released thing was a copy paste error. I don't know why it doesn't work on process, but I just tested it and this definitely works.

        func _input(event):
	if event.is_action_pressed("scroll_up"):
		print("scroll_up")
	if event.is_action_pressed("scroll_down"):
		print("scroll_down")

          cybereality ok that works.tnx
          but i dont understand why my code doesn't.
          could it be cause it is in a sub function of physics process?

            i want to use it to iterate between icons in a HBoxContainer.

            how do i get all the icons in the container?
            what i want to do is > if mousescrollup or mousescrolldown> open inventory(basicly unhide the hboxcontainer> hide the current weapon> use mouse scroll up or down to iterate between icons> press "fire" to select weapon and close inventory.

            Could be a timing issue. _input() happens as soon as any input is done, while _physics_process() happens at a fixed rate (60Hz by default). Input can happen at much higher rates. I think the default on Windows is 125Hz, but some mice are much higher (mine is 1000Hz).

            • DJM replied to this.

              You can get the container node, then use get_children() to get all the children. Or iterate and use the index numbers. Then you select or hide based on the index (this can be based on the weapon_index the mouse wheel controls).

              for icon in icon_container.get_children():
    print(icon.name, " at index: ", icon.get_index())

                how do i add a delay to the selection, cause mouse scrollwheel input is very fast
                i dont want to use a timer.

                in unity i did things like this>

                if (Time.time > nextselect):
nextselect = Time.time + 1.0
for icon in weaponInventory.get_children():
			print(icon.name, " at index: ", icon.get_index())

                however , i check if inventory is open (and call open_inventory)and do the code there. so there is no 'delta' variable i can use

                func open_Inventory():
	weaponInventory.visible = true
	for icon in weaponInventory.get_children():
			print(icon.name, " at index: ", icon.get_index())

                You would use:

                var now = OS.get_unix_time()

                That returns a millisecond value.

                var now = OS.get_unix_time()
if (now > nextselect):
    nextselect = now + 1000

                  Sorry, that was Godot 3.x code. This will work on 4.0.

                  var now = Time.get_unix_time_from_system()
if (now > nextselect):
    nextselect = now + 1.0
