Put mouse cursor to window border to make an reaction

TwistedMind

Hello,

I'm looking for to make a system like we can see in RTS: when we move the mouse on a border of the window, the camera move to the direction of the mouse.

Here a code which works, BUT it works well only in windowed mode (1024 x 768), I need a "responsive" system (for fullscreen or for a larger size) and i don't find a way to make that.

I have tried to put area's and use them as borders but it's not effective when the windows isn't the same size than the camera.

onready var windoSize = OS.get_real_window_size()

# other code... #
func _input(event):
     if event is InputEventMouseMotion:
           var mousePos = get_viewport().get_mouse_position()
          var normX = mousePos.x/windoSize.x
          var normY = mousePos.y/windoSize.y
          var XMove = false
          var YMove = false
		
          if normX < 0.05:
                  XMove = true
	          Input.set_custom_mouse_cursor(get_parent().scrollLeft, Input.CURSOR_ARROW, Vector2(16, 16))
	          camPlayer.camDir = Vector2.LEFT
		
          elif normX > 3.7:
                  XMove = true
	          Input.set_custom_mouse_cursor(get_parent().scrollRight, Input.CURSOR_ARROW, Vector2(16, 16))
	          camPlayer.camDir = Vector2.RIGHT
          else:
                 XMove = false

          if not XMove and not YMove:
	          camPlayer.set_physics_process(false)
          else:
	          camPlayer.set_physics_process(true)

TwistedMind That code should work with any window size. In what way it does not work when you change the size?

If i change de size to have 1920 x 1080, or upper than/far from 1024 x 768, the max value doesn't the same and the condition isn't completed.
The min and max of mousepos for X axis is: 0 to 3832. If i do 3832/1024 = 3,74... but 3832/1920 = 1,99, so the ratio has changed.
I should be more easier if i can "clamp" or remap the range of 0 - 3832 to 0 -> resolutionX.

But clamps function seem to be a bad choice.

TwistedMind The scroll zones in the code are calculated as percentages of total window size. You can use absolute pixel values instead if you want the zones to always be the same absolute size.

Obtained with get_viewport().get_visible_rect().size, that's it !

Thanks you.

var mousePos = get_viewport().get_mouse_position()
var window_size = get_viewport().get_visible_rect().size
		
if mousePos.x < 10:
	camPlayer.camDir = Vector2.LEFT

elif mousePos.x > window_size.x - 10:
      camPlayer.camDir = Vector2.RIGHT
