实例化后Unity3D C#面板定位

我正在实例化一个GO,它有一个面板组件(RectTransform)作为场景中存在的画布的子代：

_heroSelectUI = (GameObject)Instantiate (_heroSelectUIPrefab, GameObject.Find ("Canvas").GetComponent<Transform>());

创建它时,它获得以下值：

“左”,“上”,“右”和“下”得到一些不需要的值(可能是由于现有的画布似乎具有相同的值).

面板预制值为0,如何在实例化后将它们设置为0？我找不到RectTransform的正确变量.

解决方法:

根据documentation

For a stretching Rect Transform, it can be simpler to set the position using the offsetMin and offsetMax properties. The 07001 property specifies the corner of the lower left corner of the rect relative to the lower left anchor. The 07002 property specifies the corner of the upper right corner of the rect relative to the upper right anchor.

尝试做如下：

RectTransform rt = _heroSelectUI.GetComponent<RectTransform>();
rt.offsetMin = rt.offsetMax = Vector2.zero ;

另外,根据文档,您可以在设置父级时尝试执行此操作：

Prefabs of UI elements are instantiated as normal using the Instantiate method. When setting the parent of the instantiated UI element, it’s recommended to do it using the Transform.SetParent method with the worldPositionStays parameter set to false.

_heroSelectUI = (GameObject)Instantiate (_heroSelectUIPrefab, GameObject.Find ("Canvas").GetComponent<RectTransform>(), false);

要么 ：

_heroSelectUI = (GameObject)Instantiate (_heroSelectUIPrefab );
_heroSelectUI.GetComponent<Transform>().SetParent( GameObject.Find ("Canvas").GetComponent<RectTransform>(), false ) ;
