One-line 2D sprite shader effects for Godot 4. Free (MIT), drop-in, no dependencies.

Enable the addon and call one line:

FX.hit_flash($Sprite2D)              # white damage flash

FX.dissolve($Sprite2D)               # burn away with a glowing edge

FX.appear($Sprite2D)                 # materialize in (reverse dissolve)

FX.outline($Sprite2D, Color.YELLOW, 2.0)

FX.freeze($Sprite2D)                 # icy tint

FX.hologram($Sprite2D)               # animated sci-fi look

FX.clear($Sprite2D)                  # remove the effect

Works on any CanvasItem (Sprite2D, AnimatedSprite2D, TextureRect...). Animated calls return the Tween so you can await them. Shaders use in-shader noise — no texture dependencies. Godot 4.6+. Playable demo and full source:
