Unity UGUI的自动布局-LayoutGroup（水平布局）组件

本文介绍: i < 3;i++)创建一个空物体，并添加Horizon t alLayoutGroup 组件。创建一个子物体预制体，包含一个Te x t 组件。将子物体预制体拖拽到layoutGroup的Child Pref a b 属性中。将layoutGroup的Child Ali gnm ent 属性设置为Mid dle Cent er。运行游戏，可以看到子物体在水平方向上居中对齐。

Horizontal Layout Group | Unity UI | 1.0.0

Horizon t alLayoutGroup是Unity UGUI中的一种布局组件，用于在水平方向上对子物体进行排列和布局。它可以根据一定的规则自动调整子物体的位置和大小，使它们在水平方向上均匀分布。

Property:	Function:
Pad d in g	The padding ins ide the edg es of the layout group.
Sp acing	The sp acing between the layout elements.
Child Ali gnment	The alignment to use for the child layout elements if they don‘t fill out all the av ailable space.
Control Child Size	Whether the Layout Group controls the width and height of its child layout elements.
Use Child Scale	Whether the Layout Group conside rs the scale of its child layout elements when sizing and laying out elements. Width and Height correspond to the Scale > X and Scale > Y values in each child layout element‘s Rect Transform component. You cannot animate the Scale values using the Animator Controller
Child Force Ex pand	Whether to force the child layout elements to expand to fill additional av ailable sp ace.

HorizontalLayoutGroup 组件通过以下步骤实现水平布局：

using UnityEngine;
using UnityEngine.UI;

public class Example : MonoBehaviour
{
    public HorizontalLayoutGroup layoutGroup;
    public GameObject childPrefab;

    void Start()
    {
        for (int i = 0; i < 3; i++)
        {
            GameObject child = Instantiate(childPrefab, layoutGroup.transform);
            child.GetComponent<Text>().text = "Child " + (i + 1);
        }
    }
}

操作步骤：

using UnityEngine;
using UnityEngine.UI;

public class Example : MonoBehaviour
{
    public HorizontalLayoutGroup layoutGroup;
    public GameObject childPrefab;

    void Start()
    {
        layoutGroup.spacing = 20f;

        for (int i = 0; i < 3; i++)
        {
            GameObject child = Instantiate(childPrefab, layoutGroup.transform);
            child.GetComponent<Text>().text = "Child " + (i + 1);
        }
    }
}

using UnityEngine;
using UnityEngine.UI;

public class Example : MonoBehaviour
{
    public HorizontalLayoutGroup layoutGroup;
    public GameObject childPrefab;

    void Start()
    {
        layoutGroup.childForceExpandWidth = true;

        for (int i = 0; i < 3; i++)
        {
            GameObject child = Instantiate(childPrefab, layoutGroup.transform);
            child.GetComponent<Text>().text = "Child " + (i + 1);
        }
    }
}

using UnityEngine;
using UnityEngine.UI;

public class Example : MonoBehaviour
{
    public HorizontalLayoutGroup layoutGroup;
    public GameObject childPrefab;

    void Start()
    {
        layoutGroup.childControlWidth = false;
        layoutGroup.childControlHeight = false;

        for (int i = 0; i < 3; i++)
        {
            GameObject child = Instantiate(childPrefab, layoutGroup.transform);
            child.GetComponent<Text>().text = "Child " + (i + 1);
        }
    }
}

using UnityEngine;
using UnityEngine.UI;

public class Example : MonoBehaviour
{
    public HorizontalLayoutGroup layoutGroup;
    public GameObject childPrefab;

    void Start()
    {
        layoutGroup.childAlignment = TextAnchor.MiddleCenter;

        for (int i = 0; i < 3; i++)
        {
            GameObject child = Instantiate(childPrefab, layoutGroup.transform);
            child.GetComponent<Text>().text = "Child " + (i + 1);
        }
    }
}
