EditorGUILayout.CurveField 曲线字段

// Makes the selected GameObject follow the animation curve.
//制作选择的游戏物体跟随动画曲线。
// Usage: Generate the curves for X,Y and Z axis of your desired GameObject
// Select an Object and click Generate Curve.
// Press Play and see your object moving.
//用法：为游戏物体创建曲线X,Y 和 Z轴，选择物体并点击生成曲线。按播放看物体移动
