通过代码使用锚预设定位 UI 元素

当我们在 Unity 中定位 UI 元素时，我们会通过锚点预设来修复位置，以便将其位置正确放置在画布上。

我们选择顶部、中间、底部、拉伸和蓝色点。

如果我在 C# 代码中创建 UI 元素，我该如何做同样的事情？

I make

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

如何将左上角与蓝色点固定在一起？

UI 对象的锚点（最小值、最大值）值和枢轴点值RectTransform决定 UI 蓝色点所在位置的因素。

如果按住 Shift 键并单击每个预设，下图中圈出的属性将会发生变化。然后，您可以复制每个变量并将它们放入代码中。

这些属性由脚本控制RectTransform.anchorMin, RectTransform.anchorMax and RectTransform.pivot.

不太确定是什么Texture2D您问题中的代码与此有关，但以下是设置每个预设的函数：

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