Hello!
I've been trying to learn how to write my own shaders in Madmapper. I bought a few books and looked at books online. I was following thecode on this site https://thebookofshaders.com/02/ and now madmapper won't open. I deleted the .plist file, but it still won't open, it just hangs and I need to do a force quit. The steps I followed were...
1. open code editor
2. delete the code for the default shader
3. copy paste this code...
#ifdef GL_ES
precision mediump float;
#endif
uniform float u_time;
void main() {
gl_FragColor = vec4(1.0,0.0,1.0,1.0);
}
this code threw an error so I deleted it and started the process over again. I finally was able to get the code to work by simply copying this line vec4(1.0,0.0,1.0,1.0) but then the software hung and now I can't open it.
I've been searching for a madmapper book or tutorial that goes through the process of how to write shaders specifically in madmapper but I can't find anything. I followed this tutorial but the code doesn't work either https://www.youtube.com/watch?v=sKQ1fDIFd9M. I found a random site that taught the same technique and the error on line 31 was commented out. Clearly I have no idea what I'm doing so if someone can please help me fix my software and point me to a book or tutorial that teaches how to write MadMapper shaders SPECIFICALLY for madmapper, from the ground up, I'd greatly appreciate it!
