朋友介绍的论坛..求助关于Unity3D的问题~~

[tneey]

我打算用Unity3d做一个可视化冒泡排序. C# 写冒泡很简单，可是用在Unity3d就不是那么一回事啊。。。求大家帮我看看代码。
不知道哪里出问题了 代码如下

void Update()
{
for (i = 0; i < shapes.Length-1;i++)
{

for (j = i+1; j < shapes.Length; j++)
{
x0 = shapes[i].transform.position.x; //提取2个cube位置信息
y0 = shapes[i].transform.position.y;
z0 = shapes[i].transform.position.z;
x1 = shapes[j].transform.position.x;
y1 = shapes[j].transform.position.y;
z1 = shapes[j].transform.position.z;

isize = shapes[i].transform.localScale.y; //提取2个cube长度，用来对比大小
jsize = shapes[j].transform.localScale.y;

if (isize > jsize)
{
shapes[j].transform.position = new Vector3(Mathf.Lerp(shapes[j].transform.position.x, shapes[i].transform.position.x, speed * Time.deltaTime), shapes[1].transform.position.y, shapes[1].transform.position.z);
shapes[i].transform.position = new Vector3(Mathf.Lerp(shapes[i].transform.position.x, shapes[j].transform.position.x, speed * Time.deltaTime), shapes[0].transform.position.y, shapes[0].transform.position.z);
//交换位置
}
}
}

}

开始后就居中合体了。。

你解决了吗？

[tneey]

没。。我要通宵编程了 这个应该是update每秒几百次调用，而for循环也是每秒循环几百次，但是for里面苦逼的平移操作却来不及完成吧？ 好像涉及到协程什么的，我真的一点办法都没有。。深夜我还会来看看的~~~
