Coding a shader for the game
The only remaining task is that the file that the shader code is attempting to load is empty. The code is publicly available, but I didn’t write the code and am likely not permitted to distribute it. Visit https://glslsandbox.com/e#109644.0 and click on the show code. Copy and paste all the nearly 400 lines of code into the file shaders/glsldandbox109644. Be sure to leave a friendly comment or thank you to the talented shader programmer who published the code. Save the file and we are ready to go. The shader code is beyond the scope of the book.
In the next section, we will see the shader in all its glory.
