in my game if i press middle mouse button(or left) and move the mouse the wold map also have to move with like in the godot 2d editor window, here is my code but it’s not perfect because mouse is moving relative to the world map.
extends Node2D
var moving = false
var mouse_start
var camera_start
func _process(delta):
if Input.is_mouse_button_pressed( BUTTON_LEFT) :
if ! moving :
moving = true
mouse_start = get_global_mouse_position()
camera_start = $Camera.position
else:
var mouse_displacement_vector = (get_global_mouse_position()-mouse_start)
$Camera.position = camera_start - mouse_displacement_vector
else:
moving = false
My code sample using the ‘Input Map’ in the ‘Project Settings’ (there ‘move_map’ is caused by ‘Device 0, Middle Button’). The script is used by the Camera Node ‘Camera2D’:
extends Camera2D
var fixed_toggle_point = Vector2(0,0)
func _process(delta):
# This happens once 'move_map' is pressed
if Input.is_action_just_pressed('move_map'):
var ref = get_viewport().get_mouse_position()
fixed_toggle_point = ref
# This happens while 'move_map' is pressed
if Input.is_action_pressed('move_map'):
move_map_around()
# moves the map around just like in the editor
func move_map_around():
var ref = get_viewport().get_mouse_position()
self.global_position.x -= (ref.x - fixed_toggle_point.x)
self.global_position.y -= (ref.y - fixed_toggle_point.y)
fixed_toggle_point = ref
But using Input.is_mouse_button_pressed(BUTTON_LEFT) surely works, too. Then you can spare defining the Projects Input Map:
extends Camera2D
var fixed_toggle_point = Vector2(0,0)
var currently_moving_map = false
func _process(delta):
if Input.is_mouse_button_pressed(BUTTON_LEFT) or Input.is_mouse_button_pressed(BUTTON_MIDDLE):
# This happens once 'move_map' is pressed
if( !currently_moving_map ):
var ref = get_viewport().get_mouse_position()
fixed_toggle_point = ref
currently_moving_map = true
# This happens while 'move_map' is pressed
move_map_around()
else:
currently_moving_map = false
# this stays the same
func move_map_around():
var ref = get_viewport().get_mouse_position()
self.global_position.x -= (ref.x - fixed_toggle_point.x)
self.global_position.y -= (ref.y - fixed_toggle_point.y)
fixed_toggle_point = ref
