Max Hilbrunner 2ba6d25aa9 Revert "Rename zh_CN/zh_TW to zh_Hans/zh_Hant" 
This reverts commit 57781dc0bc.
The rename, although in line with what we did in the engine, caused problems with RTD we need to fix (or push for a fix) first.

2D 空间中的一个区域，能够检测到其他 :ref:`CollisionObject2D<class_CollisionObject2D>` 的进入或退出。

描述
----
**Area2D** 是 2D 空间中的一个区域，由一个或多个 :ref:`CollisionShape2D<class_CollisionShape2D>` 或 :ref:`CollisionPolygon2D<class_CollisionPolygon2D>` 子节点定义，能够检测到其他 :ref:`CollisionObject2D<class_CollisionObject2D>` 进入或退出该区域，同时也会记录哪些碰撞对象尚未退出（即哪些对象与其存在重叠）。
这个节点也可以在局部修改或覆盖物理参数（重力、阻尼），将音频引导至自定义音频总线。
\ **注意：**\ 使用 :ref:`PhysicsServer2D<class_PhysicsServer2D>` 创建的区域和物体可能无法按预期与 **Area2D** 交互，并且可能无法正确发出信号或跟踪对象。

返回相交的 :ref:`PhysicsBody2D<class_PhysicsBody2D>` 和 :ref:`TileMap<class_TileMap>`\ 。重叠物体的 :ref:`CollisionObject2D.collision_layer<class_CollisionObject2D_property_collision_layer>` 必须是该区域 :ref:`CollisionObject2D.collision_mask<class_CollisionObject2D_property_collision_mask>` 的一部分，才能被检测到。
出于性能原因（所有碰撞都是一起处理的），这个列表只会在每次物理迭代时发生一次更改，不会在对象移动后立即更改。请考虑使用信号。
