记下我学unity踩过的坑
private List<Vector2> postionelist = new List<Vector2>();
这个东西及其难搞,好像是vector2不能使用数组类型,可能是因为他是坐标系变量的问题,数组只能满足一个整数输出,List<>则可以
写一下list的用法吧
设置list
private List<Vector2> postionelist = new List<Vector2>();
调用list
postionelist.Clear();
for (int x = 2; x < hang - 2; x++)
{
for (int y = 2; y < lie - 2; y++)
{
postionelist.Add(new Vector2(x, y));
}
}
这里是在取随机坐标
private Vector2 Randompostion()
{
int positionidex = Random.Range(0, postionelist.Count);
Vector2 pos = postionelist[positionidex];
postionelist.RemoveAt(positionidex);
return pos;
}
list的自定义函数,看调出方法和数组一样
for (int i=0;i<4;i++) {
Vector2 poss = Randompostion();
GameObject.Instantiate(food2[1],poss , Quaternion.identity);
}
