更全的内容请看我的游戏蛮牛地址：
先看一下很普通的实现方式：
随便命名一个javascript脚本。然后复制如下的代码之后随便挂在一个对象上，观察效果。
var Point : float;//要显示的分数private var GetHitEffect : float;private var targY : float;//分数所要显示的位置Y值private var PointPosition : Vector3; //分数的显示位置var PointSkin : GUISkin;var PointSkinShadow : GUISkin;function Start() { Point = Mathf.Round(Random.Range(Point/2,Point*2)); PointPosition = transform.position + Vector3(Random.Range(-1,1),0,Random.Range(-1,1)); targY = Screen.height /2;}function OnGUI() { var screenPos2 : Vector3 = Camera.main.camera.WorldToScreenPoint (PointPosition); GetHitEffect += Time.deltaTime*30; GUI.color = new Color (1.0f,1.0f,1.0f,1.0f – (GetHitEffect – 50) / 7);//改变分数的透明度逐渐消失 GUI.skin = PointSkinShadow; GUI.Label (Rect (screenPos2.x+8 , targY-2, 80, 70), "+" + Point.ToString()); GUI.skin = PointSkin; GUI.Label (Rect (screenPos2.x+10 , targY, 120, 120), "+" + Point.ToString());}function Update() {//分数向上移动 targY -= Time.deltaTime*200;}
然后来介绍 曲线的运动方式。
新建一个脚本如下：

勤勉是通往胜利的必经之路。要是由于胆怯艰难而去另觅佳径，
