0: None: not filter, the edge is completely sharp. The calculation efficiency is the highest, but the visual effect is the worst, suitable for performance-sensitive scenarios.
1: PCF5: Use 5 sampling points for blurring. The edge has a certain smooth effect, but the blur degree is limited, suitable for medium blur requirements.
2: PCF9: Use 9 sampling points for blurring. The edge has a stronger smooth effect, suitable for high-quality shadow scenes. Calculation cost is medium, visual effect is significantly improved.
3: PCF13: Use 13 sampling points for blurring, one of the highest quality blur algorithms. The edge is very soft, suitable for scenes that require extremely
Checks if the component has a specific hide flag set.
Zh
检查组件是否设置了特定的隐藏标志。
isLayerEnable
isLayerEnable(layer:number):number
参数
layer: number
Specified layer
返回 number
En
Is the light turned on for the specified layer
Zh
灯光对指定层是否开启
isShadowLayerEnable

参数
layer: number
Specified layer
返回 number
En
Is the shadow turned on for the specified layer
Zh
阴影对指定层是否开启
onAdded
onAdded():void
返回 void
En
Called after the component is added to a node. Unlike Awake, onAdded is called even if the node is not active.
Zh
组件被添加到节点后调用，与 onAwake 不同的是，即使节点未激活也会调用 onAdded。
onAwake
onAwake():void
返回 void
En
Executed after the component is activated. At this point, all nodes and components have been created. This method is executed only once.
Zh
组件被激活后执行，此时所有节点和组件均已创建完毕，此方法只执行一次。
onDestroy
onDestroy():void
返回 void
En
Executed when the node is destroyed manually.
Zh
手动调用节点销毁时执行。
onDisable
onDisable():void
返回 void
En
Executed when the component is disabled, such as when the node is removed from the stage.
Zh
组件被禁用时执行，比如从节点从舞台移除后。
onEnable
onEnable():void
返回 void
En
Executed after the component is enabled, such as when the node is added to the stage.
Zh
组件被启用后执行，比如节点被添加到舞台后。
可选onLateUpdate
onLateUpdate():void
返回 void
En
Executed every frame during the late update phase, after the update phase.
Zh
每帧更新时执行，在 late update 阶段，update 阶段之后。
可选onPostRender
onPostRender():void
返回 void
En
Executed after rendering.
Zh
渲染之后执行。
可选onPreRender
onPreRender():void
返回 void
En
Executed before rendering.
Zh
渲染之前执行。
可选onReset
onReset():void
返回 void
En
Resets the component's parameters to their default values. If this function is implemented, the component will be reset and automatically recycled for future use.
If not reset, it will not be recycled for reuse.
