kraj0t / UsingCsCodeInHLSL.cs

Last active April 30, 2024 16:16

How to include C# code in an HLSL file - useful for sharing code between CPU and shader without duplicating any files

	// Share code between HLSL (shaders) and C#
	//
	// Limitations:
	// - Cannot use #include
	// - Must use defines to hide certain keywords, such as public, private, protected, or any other object-oriented programming keywords
	// - Use defines to convert half or fixed to your desired C# equivalent
	// - Must always write f after float literals
	// - Use #if !MY_DEFINE instead of #ifndef MY_DEFINE
	// - #define cannot be used with a value in C#, not even inside an '#if SHADER_TARGET' block. Therefore, you have two options for declaring valued constants:
	// a. Declare each constant separately in HLSL (using 'static const float MyConstant = 1.0f') and in C# (using 'const float MyConstant = 1.0f'). C# does not support 'static const'.
