我正在尝试让玩家使用MoveTowards移至空白游戏对象的位置。但是，当程序进入我在函数中设置的while循环时，Unity将冻结。我尝试了几种不同的方法来使其正常工作，但要么玩家没有一直移动，要么游戏仍然死机。提前谢谢。
public KeyCode moveL; //move left
public KeyCode moveR; //move right
public KeyCode fire; //for shooting the bullet
public int laneNum =2;
public string controlLocked = "n"; //locks control when moving
//The empty game objects for the player to move to.
public Transform LaneZero;
public Transform LaneOne;
public Transform LaneTwo;
public Transform LaneThree;
public Transform LaneFour;
//move towards variables
public float step;
public float speed =5;
Void Update()
{
if((Input.GetKeyDown(moveL)) && (laneNum > 0) && (controlLocked == "n")) //for moving the player left when A is pressed
{
laneNum -= 1; //change the lane value
controlLocked = "y";
LaneChange();
}
if((Input.GetKeyDown(moveR)) && (laneNum < 4) && (controlLocked == "n")) //for moving the player left when A is pressed
{
laneNum += 1; //change the lane value
controlLocked = "y";
LaneChange();
}
}
/function for the changing of lanes
void LaneChange()
{
if(laneNum == 0)
{
while(transform.position != LaneZero.position)
{
step = speed * Time.deltaTime;
transform.position = Vector3.MoveTowards(transform.position,LaneZero.position, step);
}
}
if(laneNum == 1)
{
while(transform.position != LaneOne.position)
{
step = speed * Time.deltaTime;
transform.position = Vector3.MoveTowards(transform.position,LaneOne.position, step);
}
}
if(laneNum == 2)
{
while(transform.position != LaneTwo.position)
{
step = speed * Time.deltaTime;
transform.position = Vector3.MoveTowards(transform.position,LaneTwo.position, step);
}
}
if(laneNum == 3)
{
while(transform.position != LaneThree.position)
{
step = speed * Time.deltaTime;
transform.position = Vector3.MoveTowards(transform.position,LaneThree.position, step);
}
}
if(laneNum == 4)
{
while(transform.position != LaneFour.position)
{
step = speed * Time.deltaTime;
transform.position = Vector3.MoveTowards(transform.position,LaneFour.position, step);
}
