Constraint the mouse in a little screen

TwistedMind

Good day,

I'm looking for to constraint the mouse to stays in the minimap's perimeter when the left button still pressed.

I know i need to use get_local_mouse_position() (because i only need local coordinates of the minmap) and warp_mouse(), but i don't understand what's append when the condition is reached.

If the mouse reachs the line, it must be warped before the line (or blocked i should say). The mouse seems to be teleported out of the godot window and not in the control's perimeter. That should be inverse, in theory.

warp_mouse() for a control node seems to be local, so why my mouse be out of the screen ?

Try this code. Cursor is just a sprite with a fake mouse cursor.

extends Node2D

onready var cursor = get_node("Cursor")
var mouse_pos = Vector2()
var mouse_speed = 3.0

func _ready():
	Input.set_mouse_mode(Input.MOUSE_MODE_HIDDEN)

func _process(delta):
	var mouse_rel = Vector2.ZERO
	if Input.is_action_pressed("mouse_up"):
		mouse_rel += Vector2.UP * mouse_speed
	if Input.is_action_pressed("mouse_down"):
		mouse_rel += Vector2.DOWN * mouse_speed
	if Input.is_action_pressed("mouse_left"):
		mouse_rel += Vector2.LEFT * mouse_speed
	if Input.is_action_pressed("mouse_right"):
		mouse_rel += Vector2.RIGHT * mouse_speed
	if mouse_rel != Vector2.ZERO:
		Input.warp_mouse_position(mouse_pos + mouse_rel)
	cursor.position = get_global_mouse_position()

func _input(event):
	if event is InputEventMouseMotion:
		mouse_pos = event.position

Yes.... and so ?

With this code, i can move the sprite in my root viewport and it is blocked in each corner of the window but my question doens't concern the main window, it concern a little window as control node.

I don't understand what you want to mean with this code.

edit: i see get_local_mouse_position() give me the min and max rect size and get_global_mouse_position() give me the position of the mouse in the world. And so the warp_mouse set the mouse in the world.

edit2: Using get_viewport().get_mouse_position and get_viewport().warp_mouse() solve my problem.

The code was an example I made some something else. So you can understand how the function works.
