Editor.RenderStaticPreview

切换到手册
public Texture2D RenderStaticPreview (string assetPath, Object[] subAssets, int width, int height);

参数

assetPath 要对其执行操作的资源。
subAssets assetPath 中所有资源的数组。
width 所创建纹理的宽度。
height 所创建纹理的高度。

返回

Texture2D 生成的纹理或 null。

描述

如果要渲染静态预览,可重载此方法。

重载后,RenderStaticPreview 可用于渲染 已转换为单个纹理的资源列表。此函数需要 用户提供的源代码,用于将资源整合在一起。创建纹理的 大小可由提供的宽度和高度确定。
如果返回 null,则使用类类型的内置图标。
