c#脚本控制shader

如图所示，c#脚本控制shader颜色。

1 public class ControlColor : MonoBehaviour
2 {
3     public Color color = new Color(1, 1, 1, 1);
4     public Material mat;
5     public void ChangeColor()
6     {
7         mat.SetVector("_Diffuse", color);
8     }
9 }

 1 [CustomEditor(typeof(ControlColor))]
 2 public class Edit_ControlColor : Editor {
 3     ControlColor scr;//脚本本体
 4     SerializedObject serObj;
 5     SerializedProperty color;
 6     SerializedProperty mat;

 8     public void OnEnable()
 9     {
10         scr = (ControlColor)target;
11         serObj = new SerializedObject(target);
12         color = serObj.FindProperty("color");
13         mat = serObj.FindProperty("mat");
14     }
15     public override void OnInspectorGUI()
16     {
17         serObj.Update();
18         EditorGUILayout.PropertyField(color,new GUIContent("Color"));
19         EditorGUILayout.PropertyField(mat,new GUIContent("Mat"));
20         serObj.ApplyModifiedProperties();
21         scr.ChangeColor();
22     }
23 }
