通過代碼

Question

使用錨預設定位UI元素當我們在UI中定位UI元素時，我們從錨預設中修復了位置，以便將其位置正確放置在畫布上。

我們選擇上，中，下，拉伸和藍色圓點。

如果我在C＃代碼中創建UI元素，我該怎麼做同樣的事情？

我做

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

我怎麼能一起解決的左上角用藍色的點？

Answer 1

錨（最小，最大）值和樞軸點值UI對象的RectTransform是確定UI藍色點位於何處的因素。

如果您按住shift鍵並單擊每個預設，您將在下面的圖像中圈選的屬性發生變化。然後您可以複製每個變量並將其放入代碼中。

這些屬性從腳本經由RectTransform.anchorMin，RectTransform.anchorMax和RectTransform.pivot控制。

不完全知道什麼是Texture2D代碼在你的問題已經做這一點，但下面的函數來設置每個預設：

//------------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); 
}
