Unity 螺旋曲线运动动画

一只蚂蚁以不变的速率，在一个均匀旋转的唱片中心沿半径向外爬行，结果蚂蚁本身就描绘出一条螺旋线

首此局启发

var to = new Vector3(x, y, z);
var from = transform.localPosition;
var distance = Vector3.Distance(from, to);


var speed = distance / during;
var euler = transform.eulerAngles.z;
var scale = transform.localScale;
var lastposition = from;
