Shadertoy to Flixel

node.js script which converts fragment source (.frag) glsl shaders from Shadertoy to Flixel. Uses a cool lib node-file-dialog, check it out!

Report errors here!

WEB VERSION

Known issues

• Shader is upside down => try to find line looks like this uv.y = 1.0 - uv.y; and remove it
• If not helped pls ask me in issues here or my discord

Supports shaders with

• #version 100 / 110 / 120 / 130
• only Image tab (can be with Common too, just copy code from here to Image)

Converted shader supports Windows, Android, Linux (?)

pls message me if it work on some other platforms!!!!!

How to use?

• install node.js
• open run.bat
• now do what windows say
• i left night vision shader for you to test this script (its not mine ofc)! NightVisionFilter.frag

How to convert it again to shadertoy?

• remove void main() function entirely
• remove lines from start to // end of ShadertoyToFlixel header inclusively
• profit!!!!!

What it exactly do?

• adding #pragma header
• adding variables from shadertoy like iResolution and iTime
• adding additional flixel_texture2D function with three arguments to use bias argument
• replacing alpha value (usually 1.0) to alpha of sprite in fragColor
• adding void main with calling void mainImage function
