mouse wheel input doesnt get detected

DJM

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

Megalomaniak

is that indentation intentional?

DJM

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?

cybereality

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

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?

DJM

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).

cybereality yeah i use a gaming mouse to work so thats probably why.

cybereality ill try it . tnx

cybereality

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())

DJM

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

DJM im on linux godot 4alpha

Try Time.get_ticks_msec()
https://docs.godotengine.org/en/latest/classes/class_time.html#class-time-method-get-ticks-msec

(But note that in 500 million years, it may cause a bug.)

cybereality

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

DJM

cybereality tnx! works fine
