GUI.Box

参数

描述

在 GUI 层上创建一个框。

通过使用 GUIContent 参数， 框可以包含文本和/或图像，以及可选的工具提示。您也可以使用 GUIStyle 调整框中项目的布局、文本颜色和其他属性。\ \ 下面是一个包含文本的框的示例：

using UnityEngine;

public class BoxExample : MonoBehaviour
{
    void OnGUI()
    {
        GUI.Box(new Rect(0, 0, Screen.width, Screen.height), "This is a box");
    }
}

下面是一个包含纹理的框的示例：

using UnityEngine;

public class BoxWithTextureExample : MonoBehaviour
{
    public Texture BoxTexture;      // Drag a Texture onto this item in the Inspector

    void OnGUI()
    {
        GUI.Box(new Rect(0, 0, Screen.width, Screen.height), BoxTexture);
    }
}

下面是一个包含 GUIContent 的框的示例，它组合了文本、纹理和工具提示：

using UnityEngine;

public class BoxWithContentExample : MonoBehaviour
{
    public Texture BoxTexture;      // Drag a Texture onto this item in the Inspector

    GUIContent content;

    void Start()
    {
        content = new GUIContent("This is a box", BoxTexture, "This is a tooltip");
    }

    void OnGUI()
    {
        GUI.Box(new Rect(0, 0, Screen.width, Screen.height), content);
    }
}

下面是一个包含文本的框的示例，该示例在 GUIStyle 中设置了相应的选项来将文本放置在框的中心位置。

using UnityEngine;

public class BoxWithTextStyleExample : MonoBehaviour
{
    GUIStyle style = new GUIStyle();

    void Start()
    {
        // Position the Text in the center of the Box
        style.alignment = TextAnchor.MiddleCenter;
    }

    void OnGUI()
    {
        GUI.Box(new Rect(0, 0, Screen.width, Screen.height), "This is a box", style);
    }
}

下面是一个包含纹理的框的示例，该示例在 GUIStyle 中设置了相应的选项来将纹理放置在框的中心位置。

using UnityEngine;

public class BoxWithTextureStyleExample : MonoBehaviour
{
    public Texture BoxTexture;              // Drag a Texture onto this item in the Inspector

    GUIStyle style = new GUIStyle();


    void Start()
    {
        // Position the Texture in the center of the Box
        style.alignment = TextAnchor.MiddleCenter;
    }

    void OnGUI()
    {
        GUI.Box(new Rect(0, 0, Screen.width, Screen.height), BoxTexture, style);
    }
}

最后是一个包含 GUIContent 的框的示例，它组合了文本、纹理和工具提示，并在 GUIStyle 参数中包含了位置信息：

using UnityEngine;

public class BoxWithContentStyleExample : MonoBehaviour
{
    public Texture BoxTexture;              // Drag a Texture onto this item in the Inspector

    GUIContent content;
    GUIStyle style = new GUIStyle();

    void Start()
    {
        content = new GUIContent("This is a box", BoxTexture, "This is a tooltip");

        // Position the Text and Texture in the center of the box
        style.alignment = TextAnchor.MiddleCenter;

        // Position the Text below the Texture (rather than to the right of it)
        style.imagePosition = ImagePosition.ImageAbove;
    }

    void OnGUI()
    {
        GUI.Box(new Rect(0, 0, Screen.width, Screen.height), content, style);
    }
}
