8.EditorGUI-折叠折叠组

---

8.1 知识点

折叠控件

bool变量 = EditorGUILayout.Foldout(bool变量, “标题名”);

bool isHide;

private void OnGUI()
{
    isHide = EditorGUILayout.Foldout(isHide, "折叠控件", false);
    // 第二个参数为true代表点击整体都能展开收起折叠，为false只能点击前面箭头展开收起折叠

    if (isHide)
    {
        EditorGUILayout.LabelField("折叠文本内容");
    }
}

折叠组控件

bool变量 = EditorGUILayout.BeginFoldoutHeaderGroup(bool变量, “标题名”);
EditorGUILayout.EndFoldoutHeaderGroup();

bool isHideGroup;

private void OnGUI()
{
    // 折叠组
    isHideGroup = EditorGUILayout.BeginFoldoutHeaderGroup(isHideGroup, "折叠组控件");
    // 和折叠的主要区别是折叠组会高亮，且折叠组需要结束组

    if (isHideGroup)
    {
        EditorGUILayout.LabelField("折叠组文本内容");
    }

    EditorGUILayout.EndFoldoutHeaderGroup();
}
