统一，C#，2D :如何将UI画布项(按钮)位置设置为与另一个游戏对象相同的位置？

Question

我试图通过代码将一个按钮显示在与方框相同的位置，这样当调用该函数时，按钮游戏对象就会移动到菜单框游戏对象所在的位置。

private RectTransform Bpos; 

// this var holds the box sprite
    public GameObject menu;

// this var hold the button game object
    public GameObject button;

// vector to hold position
    Vector3 pos;

void Start(){
// sets vector to box position
       pos = menu.transform.position;

       //declairs button recttransform
            Bpos = button.GetComponent<RectTransform>();

       // sets button recttransformto pos vector
       button.Bpos = pos;

}```
i am currently getting the error at line (button,Bpos = pos;)

 error CS1061: 'GameObject' does not contain a definition for 'Bpos' and no accessible extension method 'Bpos' accepting a first argument of type 'GameObject' could be found (are you missing a using directive or an assembly reference?)
for the life of me i cant get this to work 

Answer 1

UI使用anchoredPosition而不是transform.position。您需要将按钮的anchoredPosition设置为菜单的anchoredPosition。您可以通过访问anchoredPosition获得RectTransform。我会这样写：

void Start(){
   // get anchoredPosition of menu and save it in pos
   pos = menu.GetComponent<RectTransform>().anchoredPosition;

   // set anchoredPosition of the button to pos (anchoredPosition of menu)
   button.GetComponent<RectTransform>().anchoredPosition = pos

}
