通过代码

Question

使用锚预设定位UI元素当我们在UI中定位UI元素时，我们从锚预设中修复了位置，以便将其位置正确放置在画布上。

我们选择上，中，下，拉伸和蓝色圆点。

如果我在C＃代码中创建UI元素，我该怎么做同样的事情？

我做

Texture2D textureWhite = new Texture2D(1, 1); 
textureWhite.SetPixel(0, 0, Color.white); 
textureWhite.Apply(); 

我怎么能一起解决的左上角用蓝色的点？

Answer 1

锚（最小，最大）值和枢轴点值UI对象的RectTransform是确定UI蓝色点位于何处的因素。

如果您按住shift键并单击每个预设，您将在下面的图像中圈选的属性发生变化。然后您可以复制每个变量并将其放入代码中。

这些属性从脚本经由RectTransform.anchorMin，RectTransform.anchorMax和RectTransform.pivot控制。

不完全知道什么是Texture2D代码在你的问题已经做这一点，但下面的函数来设置每个预设：

//------------Top------------------- 
void topLeft(GameObject uiObject) 
{ 
    RectTransform uitransform = uiObject.GetComponent<RectTransform>(); 

    uitransform.anchorMin = new Vector2(0, 1); 
    uitransform.anchorMax = new Vector2(0, 1); 
    uitransform.pivot = new Vector2(0, 1); 
} 

void topMiddle(GameObject uiObject) 
{ 
    RectTransform uitransform = uiObject.GetComponent<RectTransform>(); 

    uitransform.anchorMin = new Vector2(0.5f, 1); 
    uitransform.anchorMax = new Vector2(0.5f, 1); 
    uitransform.pivot = new Vector2(0.5f, 1); 
} 


void topRight(GameObject uiObject) 
{ 
    RectTransform uitransform = uiObject.GetComponent<RectTransform>(); 

    uitransform.anchorMin = new Vector2(1, 1); 
    uitransform.anchorMax = new Vector2(1, 1); 
    uitransform.pivot = new Vector2(1, 1); 
} 

//------------Middle------------------- 
void middleLeft(GameObject uiObject) 
{ 
    RectTransform uitransform = uiObject.GetComponent<RectTransform>(); 

    uitransform.anchorMin = new Vector2(0, 0.5f); 
    uitransform.anchorMax = new Vector2(0, 0.5f); 
    uitransform.pivot = new Vector2(0, 0.5f); 
} 

void middle(GameObject uiObject) 
{ 
    RectTransform uitransform = uiObject.GetComponent<RectTransform>(); 

    uitransform.anchorMin = new Vector2(0.5f, 0.5f); 
    uitransform.anchorMax = new Vector2(0.5f, 0.5f); 
    uitransform.pivot = new Vector2(0.5f, 0.5f); 
} 

void middleRight(GameObject uiObject) 
{ 
    RectTransform uitransform = uiObject.GetComponent<RectTransform>(); 

    uitransform.anchorMin = new Vector2(1, 0.5f); 
    uitransform.anchorMax = new Vector2(1, 0.5f); 
    uitransform.pivot = new Vector2(1, 0.5f); 
} 

//------------Bottom------------------- 
void bottomLeft(GameObject uiObject) 
{ 
    RectTransform uitransform = uiObject.GetComponent<RectTransform>(); 

    uitransform.anchorMin = new Vector2(0, 0); 
    uitransform.anchorMax = new Vector2(0, 0); 
    uitransform.pivot = new Vector2(0, 0); 
} 

void bottomMiddle(GameObject uiObject) 
{ 
    RectTransform uitransform = uiObject.GetComponent<RectTransform>(); 

    uitransform.anchorMin = new Vector2(0.5f, 0); 
    uitransform.anchorMax = new Vector2(0.5f, 0); 
    uitransform.pivot = new Vector2(0.5f, 0); 
} 

void bottomRight(GameObject uiObject) 
{ 
    RectTransform uitransform = uiObject.GetComponent<RectTransform>(); 

    uitransform.anchorMin = new Vector2(1, 0); 
    uitransform.anchorMax = new Vector2(1, 0); 
    uitransform.pivot = new Vector2(1, 0); 
}
