【Unity】インスペクタの表示を動的に変更する

Last updated at Posted at 2019-02-11

インスペクタのプロパティ変更に応じて、表示内容を動的に変更する。

チェックボックスの有無で、各設定の表示/非表示が切り替わるだけの、簡単なサンプル

  • GameObject側

HogeEditor.cs
using UnityEngine;
public class HogeObject : MonoBehaviour
{
    public bool EnableShadow = false;
    public ShadowSetteing Setteing = new ShadowSetteing();

    [System.Serializable]
    public class ShadowSetteing
    {
        public Color EffectColor;
        public Vector2 Distance;
        public bool UseAlpha;
    }
}
  • Editor側
HogeObjectEditor.cs
#if UNITY_EDITOR
using UnityEditor;
[CustomEditor(typeof(HogeObject))]
public class HogeObjectEditor : Editor
{
    private HogeObject _target;

    private void Awake()
    {
        _target = target as HogeObject;
    }

    public override void OnInspectorGUI()
    {
        EditorGUI.BeginChangeCheck();

        _target.EnableShadow = EditorGUILayout.ToggleLeft("EnableShadow", _target.EnableShadow);
        if (_target.EnableShadow)
        {
            EditorGUILayout.LabelField("影の設定");
            _target.Setteing.EffectColor = EditorGUILayout.ColorField("色", _target.Setteing.EffectColor);
            _target.Setteing.Distance = EditorGUILayout.Vector2Field("距離", _target.Setteing.Distance);
            _target.Setteing.UseAlpha = EditorGUILayout.Toggle("透過", _target.Setteing.UseAlpha);
        }

        // GUIの更新があったら実行
        if (EditorGUI.EndChangeCheck())
        {
            EditorUtility.SetDirty(_target);
        }
    }
}
#endif
