# CreateMaterialInstance
|
|||
|
|
|
|||
|
|
## 1st
|
|||
|
|
|
|||
|
|
最早最根本的方法，直接在C++代码层面通过mtl::CreateVertexColor2D()函数来创建MaterialCreateInfo
|
|||
|
|
```C++
|
|||
|
|
mtl::Material2DCreateConfig cfg(GetDeviceAttribute(),"VertexColor2D",PrimitiveType::Triangles);
|
|||
|
|
|
|||
|
|
cfg.coordinate_system=CoordinateSystem2D::NDC;
|
|||
|
|
cfg.local_to_world=false;
|
|||
|
|
|
|||
|
|
AutoDelete<mtl::MaterialCreateInfo> mci=mtl::CreateVertexColor2D(&cfg);
|
|||
|
|
|
|||
|
|
material_instance=CreateMaterialInstance(mci);
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 2nd
|
|||
|
|
注册材质系统引入后的方法，通过名称"VertexColor2D"来创建MaterialCreateInfo
|
|||
|
|
```C++
|
|||
|
|
mtl::Material2DCreateConfig cfg(GetDeviceAttribute(),"VertexColor2D",PrimitiveType::Triangles);
|
|||
|
|
|
|||
|
|
cfg.coordinate_system=CoordinateSystem2D::NDC;
|
|||
|
|
cfg.local_to_world=false;
|
|||
|
|
|
|||
|
|
AutoDelete<mtl::MaterialCreateInfo> mci=mtl::CreateMaterialCreateInfo("VertexColor2D",&cfg);
|
|||
|
|
|
|||
|
|
material_instance=CreateMaterialInstance(mci);
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 3rd
|
|||
|
|
其实是第二种方法在WorkObject层面的封装
|
|||
|
|
```C++
|
|||
|
|
mtl::Material2DCreateConfig cfg(GetDeviceAttribute(),"VertexColor2D",PrimitiveType::Triangles);
|
|||
|
|
|
|||
|
|
cfg.coordinate_system=CoordinateSystem2D::NDC;
|
|||
|
|
cfg.local_to_world=false;
|
|||
|
|
|
|||
|
|
material_instance=CreateMaterialInstance("VertexColor2D",&cfg);
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 4th
|
|||
|
|
是更进一步的封装，通过材质配置文件连带Material2DCreateConfig的具体配置都进行了封闭。
|
|||
|
|
```C++
|
|||
|
|
AssetPath path(":/asset/test_material.mtl");
|
|||
|
|
|
|||
|
|
material_instance=CreateMaterialInstance(path);
|
|||
|
|
```
