Horizo??ntalGroup特性：用于在檢查器中水平分組多個屬性。寬度可以指定為百分比或像素。0到1之間的所有值都將視為百分比。如果寬度為0，則會自動調(diào)整列的大小。左右邊距只能以像素為單位指定。

【Horizo??ntalGroup】制作一個水平分組

    [HorizontalGroup]
    public int A;

    [HorizontalGroup("Group 1", LabelWidth = 20)]
    public int C;

    [HorizontalGroup("Group 1")]
    public int D;

    [HorizontalGroup("Group 1")]
    public int E;

也可以在一個橫向Group中分類不同的BoxGroup

    [HorizontalGroup("Split", 0.5f, LabelWidth = 40)]
    [BoxGroup("Split/Left")]
    public int L;
    [BoxGroup("Split/Left")]
    public int N;
    [BoxGroup("Split/Right")]
    public int M;
    [BoxGroup("Split/Right")]
    public int O;

劃分一個Buttons in Boxes折頁，在這個折頁中劃分一個Buttons in Boxes/Horizontal 組，然后在這個Horizontal Group中劃分兩個Box

    [Button(ButtonSizes.Large)]
    [FoldoutGroup("Buttons in Boxes")]
    [HorizontalGroup("Buttons in Boxes/Horizontal")]
    [BoxGroup("Buttons in Boxes/Horizontal/One")]
    public void Button1() { }

    [Button(ButtonSizes.Large)]
    [BoxGroup("Buttons in Boxes/Horizontal/Two")]
    public void Button2() { }

    [Button]
    [HorizontalGroup("Buttons in Boxes/Horizontal", Width = 60)]
    [BoxGroup("Buttons in Boxes/Horizontal/Double")]
    public void Accept() { }

    [Button]
    [BoxGroup("Buttons in Boxes/Horizontal/Double")]
    public void Cancel() { }

輔助類設(shè)置：MarginLeft、MarginRight（左右邊距）、PaddingLeft、PaddingRight（組與組的邊距）、MinWidth與MaxWidth間距，設(shè)置Title標題

using Sirenix.OdinInspector;
using UnityEngine;

public class HorizontalGroupAttributeExample : MonoBehaviour
{
    [HorizontalGroup]
    public int A;

    [HorizontalGroup("Group 1", LabelWidth = 20)]
    public int C;

    [HorizontalGroup("Group 1")]
    public int D;

    [HorizontalGroup("Group 1")]
    public int E;

    [PropertySpace(40, 40)]
    public string space = "";

    [HorizontalGroup("Split", 0.5f, LabelWidth = 40)]
    [BoxGroup("Split/Left")]
    public int L;
    [BoxGroup("Split/Left")]
    public int N;
    [BoxGroup("Split/Right")]
    public int M;
    [BoxGroup("Split/Right")]
    public int O;

    [PropertySpace(40, 40)]
    public string space1 = "";

    [Button(ButtonSizes.Large)]
    [FoldoutGroup("Buttons in Boxes")]
    [HorizontalGroup("Buttons in Boxes/Horizontal")]
    [BoxGroup("Buttons in Boxes/Horizontal/One")]
    public void Button1() { }

    [Button(ButtonSizes.Large)]
    [BoxGroup("Buttons in Boxes/Horizontal/Two")]
    public void Button2() { }

    [Button]
    [HorizontalGroup("Buttons in Boxes/Horizontal", Width = 60)]
    [BoxGroup("Buttons in Boxes/Horizontal/Double")]
    public void Accept() { }

    [Button]
    [BoxGroup("Buttons in Boxes/Horizontal/Double")]
    public void Cancel() { }
}
