[SOLVED] Analog axis strength issue

[pikadon92]

As I test my analog controls, sometimes the coordinates return to the original position even though I'm keeping the analog in one direction, though this happens when I tilt it to another direction.

Given the following var that I set as the following actions:

export (String) var input_left = "ui_left"
export (String) var input_right = "ui_right"
export (String) var input_up = "ui_up"
export (String) var input_down = "ui_down"

var dir = Vector2()

I have written a function where after taking event as an input, it gives Vector2 as an output:

func directional_event(event)->Vector2:
	if event is InputEventJoypadMotion:
		if event.get_action_strength(input_left):
			dir.x = -event.get_action_strength(input_left)
		elif event.get_action_strength(input_right):
			dir.x = event.get_action_strength(input_right)
		elif event.get_action_strength(input_up):
			dir.y = -event.get_action_strength(input_up)
		elif event.get_action_strength(input_down):
			dir.y = event.get_action_strength(input_down)
		else:
			dir = Vector2()
	return dir
	pass

I have observed that as I, say, turn right, then go upwards a little, the vector resets as (0, 0). Does anyone how I could fix this? My initial solution is to remove the "dir = Vector2()" branch, but the function won't return Vector2() once I let go of the analog.

Okay, so I didn't account for deadzones while implementing analog controls. but the problem still exists, only that it's limited to rotation (eg. right to top-right to up). Maybe I need to get the axis number...

Found the solution myself. I can check whether the event is on a specific axis by calling event.is_action(action) where action is the name of either direction of an axis. This is what I did that works:

func directional_event(event)->Vector2:
    if event is InputEventJoypadMotion:
        if event.is_action(input_left):
		if event.get_action_strength(input_left):
			dir.x = -event.get_action_strength(input_left)
		else:
			dir.x = event.get_action_strength(input_right)
	elif event.is_action(input_up):
		if event.get_action_strength(input_up):
			dir.y = -event.get_action_strength(input_up)
		else:
			dir.y = event.get_action_strength(input_down)
        return dir
        pass
