要应用的材质值代码块。
MaterialPropertyBlock is used by Graphics.RenderMesh and Renderer.SetPropertyBlock. Use
it in situations where you want to draw
multiple objects with the same material, but slightly different properties. For example, if you
want to slightly change the color of each mesh drawn. Changing the render state is not supported.
Unity 的地形引擎使用 MaterialPropertyBlock 绘制树；它们全都使用
相同材质，但是每棵树具有不同的颜色、缩放和风力系数。
The block passed to Graphics.RenderMesh or Renderer.SetPropertyBlock is copied, so the most efficient way of using it is
to create one block and reuse it for all DrawMesh calls. Use SetFloat, SetVector, SetColor, SetMatrix, SetTexture, SetBuffer to add or replace values.
Note that this is not compatible with SRP Batcher. Using this in the Universal Render Pipeline (URP), High Definition Render Pipeline (HDRP) or a custom render pipeline based on the Scriptable Render Pipeline (SRP) will likely result in a drop in performance.

| HasBuffer | Checks if MaterialPropertyBlock has the ComputeBuffer property with the given name or name ID. To set the property, use SetBuffer. |
| HasColor | Checks if MaterialPropertyBlock has the Color property with the given name or name ID. To set the property, use SetColor. |
| HasConstantBuffer | Checks if MaterialPropertyBlock has the ConstantBuffer property with the given name or name ID. To set the property, use SetConstantBuffer. |
| HasFloat | Checks if MaterialPropertyBlock has the Float property with the given name or name ID. To set the property, use SetFloat. |
| HasInt | This method is deprecated. Use HasFloat or HasInteger instead. |
| HasInteger | Checks if MaterialPropertyBlock has the Integer property with the given name or name ID. To set the property, use SetInteger. |
| HasMatrix | Checks if MaterialPropertyBlock has the Matrix property with the given name or name ID. This also works with the Matrix Array property. To set the property, use SetMatrix. |
| HasProperty | Checks if MaterialPropertyBlock has the property with the given name or name ID. To set the property, use one of the Set methods for MaterialPropertyBlock. |
| HasTexture | Checks if MaterialPropertyBlock has the Texture property with the given name or name ID. To set the property, use SetTexture. |
| HasVector | Checks if MaterialPropertyBlock has the Vector property with the given name or name ID. This also works with the Vector Array property. To set the property, use SetVector. |
| SetBuffer | Set a buffer property. |
| SetColor | 设置颜色属性。 |
| SetConstantBuffer | Sets a ComputeBuffer or GraphicsBuffer as a named constant buffer for the MaterialPropertyBlock. |
| SetFloat | 设置浮点属性。 |
| SetFloatArray | 设置浮点数组属性。 |
| SetInt | This method is deprecated. Use SetFloat or SetInteger instead. |
| SetInteger | Adds a property to the block. If an integer property with the given name already exists, the old value is replaced. |
