Juice Shaders Lite
18d oldGDScript
Three free, drop-in 2D shaders for Godot 4: hit_flash, outline, and dissolve. Plain canvas_item shaders, documented, with copy-paste GDScript to animate them. This is the free "lite" version. The full Juice Shaders pack adds 9 more effects (CRT, shockwave, water, palette remap, dither, shine sweep, pixelate, wind sway, grayscale fade): https://janeduardo19.itch.io/juice-shaders-12-game-feel-shaders-for-godot-4 These shaders come from my own game, Sinless Land, a folklore deckbuilder made in Godot 4: https://janeduardo19.itch.io/sinless-land
