Using materials with C# scripts

All the parameters of a material asset that you see in the Inspector window are accessible via script, giving you the power to change or animate how a material works at runtime.

This allows you to modify numeric values on the material, change colours, and swap textures dynamically during gameplay. Some of the most commonly used functions to do this are:

函数名称 用途
SetColor 更改材质的颜色(例如反照率着色颜色)
SetFloat 设置浮点值(例如,法线贴图乘数)
SetInt 在材质中设置整数值
SetTexture 为材质分配新纹理

完整的材质处理函数列表可以参考 Material 类脚本参考

One important note is that these functions only set properties that are available for the current Unity shader on the material. This means that if you have a shader that doesn’t use any textures, or if you have no shader bound at all, calling SetTexture will have no effect. This is true even if you later set a shader that needs the texture. For this reason it is recommended to set the shader you want before setting any properties, however once you’ve done that you can switch from one shader to another that use the same textures or properties and values will be preserved.

These functions work as you would expect for all simple shaders such as the legacy shaders, and the built-in shaders other than the Standard Shader (for example, the particle, sprite, UI and unlit shaders). For a material using the Standard Shader however, there are some further requirements which you must be aware of before being able to fully modify the material.
