This repository is a godot port of Brackeys Unity 2D GLOW tutorial.
You can make part of sprite glow,and change the glow color at runtime.
There is also a better(I think) hdr color picker in this repository:
The player's material will set specific hdr color to part of sprite, and the WorldEnvironment node in main scene will make all hdr color glow.
-
The main idea comes from Brackeys.
-
The sprites is created by ansimuz.

Some of the code in hdr_color_picker.gd is from UnityCsReference.
