UnityEditor 基础篇

记录一下常用的编辑器类型，然后把它们集中在一个窗口，以便使用。

代码部分

一. 建一个类

Editor目录下新建类 MyLayoutWindow ,继承 EditorWindow。
编写一个静态方法，用来打开窗口。

public class MyLayoutWindow : EditorWindow {
    [MenuItem("Tools/布局窗口")]
    static public void ShowWindow() {
        EditorWindow window = EditorWindow.GetWindow<MyLayoutWindow>();
        window.minSize = new Vector2(400, 450);
        window.maxSize = new Vector2(400, 450);
        window.Show();
    }

    public void OnGUI() {

    }
}

这样就可以愉快得在“Tools/布局窗口”下打开窗口了。

二. 开始写OnGUI里面的布局

坐标
为了美观，把二维三维放在同一水平上，所以在前后各加上EditorGUILayout.BeginHorizontal();
EditorGUILayout.EndHorizontal();
即可，后面会频繁用到。
EditorGUILayout.Space();
只是单纯为了中间留点间隔。

private Vector2 mVec2;
private Vector3 mVec3;
private Vector4 mVec4;

public void OnGUI() {
    EditorGUILayout.BeginHorizontal();
    this.mVec2 = EditorGUILayout.Vector2Field("二维坐标", this.mVec2, GUILayout.MaxWidth(150));
    this.mVec3 = EditorGUILayout.Vector3Field("三维坐标", this.mVec3, GUILayout.MaxWidth(250));
    EditorGUILayout.EndHorizontal();
    this.mVec4 = EditorGUILayout.Vector4Field("四维坐标", this.mVec4);
}

颜色

private Color mColor;

public void OnGUI() {
    this.mColor = EditorGUILayout.ColorField(this.mColor);
}

滑块

private float mSlider;

public void OnGUI() {
    this.mSlider = EditorGUILayout.Slider(this.mSlider, 0, 10);
}

下拉框
这里需要先定义一个枚举类

[Serializable]
public enum ShowType{
    None = 0,
    IntType = 1,
    FloatType = 2,
    StrType = 3
}

private int mPopupIndex, mLayer;
private string[] mPopupStrArr = new[]{
        "第一",
        "第二",
        "第三"
    };
private int[] mPopupIntArr = new[]{
        0,1,2
    };
private string mTag;

public void OnGUI() {
    EditorGUILayout.BeginHorizontal();
    this.mPopupIndex = EditorGUILayout.Popup(this.mPopupIndex, mPopupStrArr, GUILayout.MaxWidth(70));
    EditorGUILayout.LabelField(this.mPopupIndex.ToString(), GUILayout.MaxWidth(30));
    this.mPopupIndex = EditorGUILayout.IntPopup(this.mPopupIndex, mPopupStrArr, mPopupIntArr, GUILayout.MaxWidth(70));
    EditorGUILayout.LabelField(this.mPopupIndex.ToString(), GUILayout.MaxWidth(30));
    //自定义枚举下拉框
    this.mType = (ShowType)EditorGUILayout.EnumPopup(this.mType, GUILayout.MaxWidth(70));
    EditorGUILayout.LabelField(this.mType.ToString(), GUILayout.MaxWidth(70));
    EditorGUILayout.EndHorizontal();
    EditorGUILayout.Space();
    EditorGUILayout.BeginHorizontal();
    //Tag标签下拉框
    EditorGUILayout.LabelField("TagSelect:", GUILayout.MaxWidth(70));
    this.mTag = EditorGUILayout.TagField(this.mTag, GUILayout.MaxWidth(70));
    //Layer层下拉框
    EditorGUILayout.LabelField("LayerSelect:", GUILayout.MaxWidth(80));
    this.mLayer = EditorGUILayout.LayerField(this.mLayer, GUILayout.MaxWidth(70));
    EditorGUILayout.EndHorizontal();
}

提示框
这里不浪费空间，加了个小按钮

public void OnGUI() {
    if (GUILayout.Button("点我")) {
        EditorUtility.DisplayDialog("标题", "提示内容", "确定", "取消");
    }
｝

勾选+折叠

private bool mIsSelectTog, mIsFoldout, mIsTogGroup;
private bool[] mIsGroupTogs = new bool[2] { false, false};

public void OnGUI() {
    this.mIsSelectTog = EditorGUILayout.Toggle("显示折叠", this.mIsSelectTog);
    if (this.mIsSelectTog) {
        this.mIsFoldout = EditorGUILayout.Foldout(this.mIsFoldout, "折叠");
        if (this.mIsFoldout) {
            this.mIsTogGroup = EditorGUILayout.BeginToggleGroup("选择：", this.mIsTogGroup);
            mIsGroupTogs[0] = EditorGUILayout.ToggleLeft("111", mIsGroupTogs[0]);
            mIsGroupTogs[1] = EditorGUILayout.ToggleLeft("222", mIsGroupTogs[1]);
            EditorGUILayout.EndToggleGroup();
        }
    }
｝

动画片段

private AnimationCurve mCurve = new AnimationCurve();

public void OnGUI() {
    this.mCurve = EditorGUILayout.CurveField("动画片段", this.mCurve);
}

对象选择框

private Object mObj;
private Texture mTexture;

public void OnGUI() {
    //type-Object
    this.mObj = EditorGUILayout.ObjectField("选择object", this.mObj, typeof(Object));
    //type-Texture
    this.mTexture = (Texture)EditorGUILayout.ObjectField("选择图片", this.mTexture, typeof(Texture), true);
}

路径选择

private string mSelectPath;

public void OnGUI() {
    if (GUILayout.Button("选择", GUILayout.MaxWidth(80))) {
        this.mSelectPath = EditorUtility.OpenFilePanel("选择文件", "", "");
    }
    this.mSelectPath = EditorGUILayout.TextField(this.mSelectPath, GUILayout.MaxWidth(320), GUILayout.MaxHeight(20));
}

提示

public void OnGUI() {
    EditorGUILayout.BeginHorizontal();
    EditorGUILayout.HelpBox("oh my god!!!!!", MessageType.Error);
    EditorGUILayout.HelpBox("oh my god!!!!!", MessageType.Warning);
    EditorGUILayout.HelpBox("oh my god!!!!!", MessageType.Info);
    EditorGUILayout.EndHorizontal();
    EditorGUILayout.HelpBox("oh my god!!!!!", MessageType.None);
}

菜单

void OnGUI()
{
    if (GUILayout.Button("test", EditorStyles.toolbarDropDown, GUILayout.Width(100)))
    {
        var menu = new GenericMenu();
        menu.AddItem(new GUIContent("1"), false, ()=>{
            Debug.Log("1");
        });
        menu.AddItem(new GUIContent("2"), false, () => {
            Debug.Log("2");
        });
        menu.AddItem(new GUIContent("3"), false, () => {
            Debug.Log("3");
        });
        menu.ShowAsContext();
    }
}
