JavaScript => var eventMask: int;
C# => int eventMask;

Description 描述

Mask to select which layers can trigger events on the camera.

遮挡相机的触发事件图层

Just as the camera's cullingMask determines if the camera is able to see the GameObject, the event mask determines whether the GameObject is able to receive mouse events. Only objects visible by the camera and whose layerMask overlaps with the camera's eventMask will be able to receive OnMouseXXX events. Setting this mask to zero will improve performance and is recommended if you don't use OnMouseXXX events. See Layers for more information.

正如cullingMask确定相机是否能够看到游戏对象，事件掩遮挡决定游戏物体是否能够接收鼠标事件。只有相机可见的对象，并且该对象遮挡层与相机的 eventMask 重叠，能够接收 OnMouseXXX 事件。将此遮挡设置为零将会提高性能，建议如果你不使用 OnMouseXXX 事件。有关详细信息，请参阅图层。
