LTSpline

之前说老是报错，其实是自己二了，多写了一个

以下这两种都可以满足条件：

cr= new LTSpline(new Vector3[]{new Vector3(0f,0f,0f),new Vector3(5f,10f,0f),new Vector3(15f,25f,0f),new Vector3(45f,35f,0f),new Vector3(60f,55f,0f)});cr = new LTSpline( new Vector3[] {trans[0].position, trans[1].position, trans[2].position, trans[3].position, trans[4].position} );
