My Global Script Here


My buy function here

Note : Just I want to know how to change my sprite texture with global script

  • Rather than just example code, I think you need to learn about getters and setters. Once they click this should be quite easy. The following link will show example code of setters and getters as well as have some explanation of them, plus video if preferred:

I want to change sprite when buy different sprite in store.

The buy button should have a button pressed signal you can use. I see you already use a button pressed signal for the GlobalCoin stuff in there, not sure if it's the same button. You would get the relevant node and call the relevant get/set methods of the sprite property from there to change it. Or have 2 sprite nodes one visible one hidden by default and just toggle their visibility on button pressed.

      Have a variable in there for players NodePath and a getter/setter functions to get and set the variables value, then in your player script you use the setter to assign player nodes NodePath to that variable in global. Now you have a variable holding Player node path you can use to easily get the player node from within the global script, or from any other scripted node via the global script getter function.

          Megalomaniak Okay last question, how can I create setget for my Player's sprite.
          I tried something but i have issue. var player: var = load("res://scenes/Player.tscn") setget _set_skin, _get_skin

            No, you should store the player nodes NodePath in the variable. Not the file path. NodePath is the scene tree path of the node during runtime.
