Question

I am trying to move the camera by holding down the middle mouse button. Below is the code I have so far, but it is not working. Keep in mind, I already have the key defined in the Input map. Below is the code I have so far, I would appreciate feedback, thanks.

extends Camera2D

var dragStartMousePos = Vector2.ZERO
var dragStartCameraPos = Vector2.ZERO
var isDragging : bool = false

#Pan camera with mouse wheel button
func ClickAndDrag():
if !isDragging and Input.is_action_pressed(“camera_pan”):
dragStartMousePos = get_viewport().get_mouse_position()
dragStartCameraPos = position
isDragging = true

if isDragging and Input.is_action_pressed("camera_pan"):
	isDragging = false

if isDragging:
	var moveVector = get_viewport().get_mouse_position() - dragStartMousePos
	position = dragStartCameraPos - moveVector * 1/zoom.x

rotate_y(mouse_movement * sensitivity)
