static function *DrawGizmo* (*gizmo* : [GizmoType](../Editor_Enumerations/GizmoType/GizmoType.html)) :
DrawGizmo

*Description* 描述

Defines when the gizmo should be invoked for drawing.

当 gizmo 应该绘制调用时定义。

参见：[GizmoType](../Editor_Enumerations/GizmoType/GizmoType.html)

```
/// The RenderLightGizmo function will be called if the light is not selected.
/// The gizmo is drawn when picking.
///如果灯光不选择RenderLightGizmo函数将被调用
///当点选时gizmo被绘制

@DrawGizmo (GizmoType.NotSelected | GizmoType.Pickable)
static function RenderLightGizmo (light : Light, gizmoType : GizmoType) {
	var position = light.transform.position;
	// Draw the light icon //绘制灯光图标
	// (A bit above the one drawn by the builtin light gizmo renderer)
	Gizmos.DrawIcon (position + Vector3.up, "Light Gizmo.tiff");

// Are we selected? Draw a solid sphere surrounding the light
	//当选择时，围绕灯光绘制一个球形
	if ((gizmoType & GizmoType.SelectedOrChild) != 0) {
		// Indicate that this is the active object by using a brighter color.
		//使用明亮的颜色，表明这是激活的物体
		if ((gizmoType & GizmoType.Active) != 0)
			Gizmos.color = Color.red;
		else
			Gizmos.color = Color.red * 0.5;
		Gizmos.DrawSphere (position, light.range);
	}

• static function *DrawGizmo* (*gizmo* : [GizmoType](../Editor_Enumerations/GizmoType/GizmoType.html),
*drawnGizmoType* : Type) : DrawGizmo

*Description* 描述

Same as above. drawnGizmoType determines of what type the object we are
drawing the gizmo of has to be.

同上。drawnGizmoType 确定了要绘制 gizmo 物体是什么类型。

If drawnGizmoType is null, the type will be determined from the first
parameter of the draw gizmo method.

如果 drawnGizmoType 类型为 null，该类型将从绘制 gizmo 方法的首个参数来确定。
