How do i fix this code? im making a tamagotchi game and i need to drag the window when you click on the body of ther tamagotchi. When its dragged, it jitters and somtimes teleports too far. thanks!
var dragPoint = null
func _on_area_2d_input_event(viewport: Node, ev: InputEvent, shape_idx: int) -> void:
if ev is InputEventMouseButton:
if ev.button_index == MOUSE_BUTTON_LEFT:
if ev.pressed:
# Grab it.
dragPoint = Vector2i(get_global_mouse_position()) - get_tree().get_root().position
else:
# Release it.
dragPoint = null
if ev is InputEventMouseMotion and dragPoint != null:
get_tree().get_root().set_position(Vector2i(get_global_mouse_position()) - dragPoint)
get_tree().root will give you the window, which I believe uses screen-space coordinates, but get_global_mouse_position() uses the canvas layer/window coordinates.
To get the mouse screen coordinate position use DisplayServer.mouse_get_position()
var dragPoint = null
# Called when the node enters the scene tree for the first time.
func _ready():
get_tree().get_root().set_transparent_background(true)
var poly : PackedVector2Array = $Poly.polygon
DisplayServer.window_set_mouse_passthrough(poly)
func _input(event: InputEvent) -> void:
if event is InputEventMouseMotion:
if not dragPoint: return
get_tree().root.position = DisplayServer.mouse_get_position() - Vector2i(dragPoint)
if event is InputEventMouseButton:
if event.button_index == MOUSE_BUTTON_LEFT:
if event.pressed == false:
dragPoint = false
func _on_area_2d_input_event(viewport: Node, ev: InputEvent, shape_idx: int) -> void:
if ev is InputEventMouseButton:
if ev.button_index == MOUSE_BUTTON_LEFT:
if ev.pressed:
# Grab it.
dragPoint = get_local_mouse_position()
