Question

JavaScript => public static function ScreenPointToWorldPointInRectangle(rect: RectTransform, screenPoint: Vector2, cam: Camera, out worldPoint: Vector3): bool;
C# => public static bool ScreenPointToWorldPointInRectangle(RectTransform rect, Vector2 screenPoint, Camera cam, out Vector3 worldPoint);

Parameters 参数

rect	The RectTransform to find a point inside.
cam	The camera associated with the screen space position.
screenPoint	Screen space position.
worldPoint	Point in world space.

Returns 返回

bool Returns true if the plane of the RectTransform is hit, regardless of whether the point is inside the rectangle.

Description 描述

Transform a screen space point to a position in world space that is on the plane of the given RectTransform.

屏幕空间点转换为世界空间点，该点在矩形变换的平面上。

The cam parameter should be the camera associated with the screen point. For a RectTransform in a Canvas set to Screen Space - Overlay mode, the cam parameter should be null.

该cam 参数应该是该相机关联的屏幕点。对于在画布上的矩形变换设置该屏幕空间为-Overlay模式，cam 参数应该为空。

When ScreenPointToLocalPointInRectangle is used from within an event handler that provides a PointerEventData object, the correct camera can be obtained by using PointerEventData.enterEventData (for hover functionality) or PointerEventData.pressEventCamera (for click functionality). This will automatically use the correct camera (or null) for the given event.

当ScreenPointToLocalPointInRectangle从事件处理器内部提供一个PointerEventData对象被使用时，相机可以通过使用PointerEventData.enterEventData(为悬停功能)或者 PointerEventData.pressEventCamera(为单击功能)被获取。该函数将会自动对指定事件使用正确的相机(或者空)。
