Graphics programming - Unity 3D shaders - 005.

If you working with shaders and you get this error

Shader error in '': Parse error: syntax error, unexpected TVAL_ID

Go to console area and find where is the line of source code ...

Shader error in '': Parse error: syntax error, unexpected TVAL_ID at line 15

In my case was an old defined source code ZWriteoff, after I change it with ZWrite Off the shader is compileted.

Godot : Fix error on godot 4.1.1. mono with C#.

If you want to use Godot mono with C# on Windows O.S. then you need to download it and follow the steps from the official website.

One step need to use the .NET version and sometime can have an error like this when you try to build the project:

Exception: "NuGet.Packaging.Core.PackagingException: Unable to find fallback package folder ...

Go to your mono folder and create the GodotNuGetFallbackFolder on this path:

C:\Users\YOUR_username\AppData\Roaming\Godot\mono

I build the project and works well:

Build succeeded.

Shader Editor - example 004.

Another example with the Shader Editor android application, this time simpler:

This shader displays some concentric circles that change their colors according to a sine and cosine formula.

This is the source code for the shader:

#ifdef GL_FRAGMENT_PRECISION_HIGH
precision highp float;
#else
precision mediump float;
#endif

uniform vec2 resolution;
uniform float time;

void main(void) {
 float mx = max(resolution.x, resolution.y);
 vec2 uv = gl_FragCoord.xy / mx;
 vec2 center = resolution / mx * 0.5;
 float t = time * 10.0;

 gl_FragColor = vec4(cos(t+distance(uv, center) / 222.0)+1.0,
  vec2(sin(t - distance(uv, center) * 76.0)) * 10.5,
  1.0);
}
