大家好，又见面了，我是你们的朋友全栈君。
Custom Value Drawer Attribute 特性，允许用户自定义一个绘制方法，字段将以自定的绘制方式展示在Inspector中，非常灵活。
含有Label和不含有Label的字段
[CustomValueDrawer("HaveLabelNameFunction")]
public string HaveLabelName;
[CustomValueDrawer("NoLabelNameFunction")]
public string NoLabelName;
public string HaveLabelNameFunction(string tempName, GUIContent label)
{
return EditorGUILayout.TextField(tempName);
}
public string NoLabelNameFunction(string tempName, GUIContent label)
{
return EditorGUILayout.TextField(label,tempName);
}
绘制Slider滑动条
public float Max = 100, Min = 0;
[CustomValueDrawer("MyStaticCustomDrawerStatic")]
public float CustomDrawerStatic;
private static float MyStaticCustomDrawerStatic(float value, GUIContent label)
{
return EditorGUILayout.Slider(label, value, 0f, 10f);
}
[CustomValueDrawer("MyStaticCustomDrawerInstance")]
public float CustomDrawerInstance;
private float MyStaticCustomDrawerInstance(float value, GUIContent label)
{
return EditorGUILayout.Slider(label, value, this.Min, this.Max);
}
[CustomValueDrawer("MyStaticCustomDrawerArray")]
public float[] CustomDrawerArray = new float[] { 3f, 5f, 6f };
private float MyStaticCustomDrawerArray(float value, GUIContent label)
{
return EditorGUILayout.Slider(value, this.Min, this.Max);
}
