可以在代码中绘制一些输出结果或者中间输出内容，比如计算后的包围盒等等
类变量
| 方法 | 作用 |
|---|---|
| color | 控制输出颜色 |
| matrix | Set the gizmo matrix used to draw all gizmos. |
| DrawCube | 绘制立方体 |
| DrawWireCube | 线框立方体 |
| DrawLine | 绘制直线 |
| DrawMesh | 绘制Mesh |
| DrawWireMesh | 线框Mesh |
| DrawRay | 方向射线 |
| DrawSphere | |
| DrawWireSphere |
绘制方式
All gizmo drawing has to be done in either OnDrawGizmos or OnDrawGizmosSelected functions of the script.
当然结果只能在Scene视图中查看
测试
比如我们要绘制一个输出的包围盒
private Bounds needDraw ;
void OnDrawGizmos()
{
Gizmos.color = new Color(1, 0, 1, 0.5F);
Gizmos.DrawWireCube(needDraw.center, needDraw.size);
}
