EditorGUI.CurveField 曲线字段

// Makes the selected GameObject follow the animation curve.
//使选择的对象跟随动画曲线变化
// Usage: Generate the curves for X,Y and Z axis of your desired GameObject
//用法：为所需的游戏物体，生成X、Y、Z曲线
// Select an Object and click Generate Curve.
//选择一个对象，然后点击生成曲线
// Press Play and see your object moving.
//播放并且观察对象移动
