Class MonoGameGlslRewriter

Namespace: ShadowDusk.GLSL

Assembly: ShadowDusk.GLSL.dll

Rewrites the modern GLSL that SPIRV-Cross emits (#version 140, in/out, in_var_TEXCOORD0, texture(), a named UBO) into the legacy MojoShader dialect that MonoGame's OpenGL runtime expects (legacy varying names, gl_FragColor, texture2D(), ps_uniforms_vec4[]). This is a pure string transform with no external dependencies.

Methods

Rewrite(string, ShaderStage, IReadOnlyList<int>?)

Rewrites SPIRV-Cross GLSL into the MonoGame/MojoShader dialect for the given stage.

public static MonoGameGlslResult Rewrite(string glsl, ShaderStage stage, IReadOnlyList<int>? samplerSlots = null)

Parameters

glsl string: The modern GLSL emitted by SPIRV-Cross.
stage ShaderStage: The shader stage being rewritten (vertex or pixel).
samplerSlots IReadOnlyList<int>: The GL texture unit each sampler declaration must be numbered with, indexed by the order SPIRV-Cross declares the combined samplers. Supplying it is what makes the emitted ps_s{N} follow the shader's register(sN) / declaration order the way fxc (and therefore mgfxc) allocates, rather than SPIRV-Cross's first-use numbering (GitHub issue #189). When null — or shorter than the number of samplers found — the positional fallback applies, which is correct precisely when the two orders coincide.

Returns

MonoGameGlslResult: The rewritten GLSL together with the discovered samplers, uniform register count, and (for the vertex stage) vertex attributes.
