遮挡入口 (Occlusion Portal) 可以是打开或关闭状态。遮挡入口关闭时,它将遮挡其他游戏对象。遮挡入口打开时,它不会遮挡其他游戏对象。
如果场景中有一个处于打开和关闭状态的游戏对象(例如门),可以创建一个在遮挡剔除系统中表示该游戏对象的遮挡入口。然后,可以根据该游戏对象的状态来设置遮挡入口的打开状态。无需将 Occlusion Portal 组件置于其表示的游戏对象上。
使用脚本将 Occlusion Portal 组件的 open 属性设置为所需状态。
void OpenDoor() {
// Toggle the Occlusion Portal's open state, so that Unity renders the GameObjects behind it
myOcclusionPortal.open = true;
// Call a function that plays a door opening animation, or otherwise hides the GameObject
…
}
