我如何只用1个坐标跟随我的玩家位置来移动敌人

问题描述

我正在制作2D游戏，我只希望我的敌人跟随我的玩家并仅靠Y坐标跟随部分，这意味着如果我的玩家向上或向下移动，敌人将会跟随但不会向前移动。 这是我当前在敌人脚本中的代码：

if (Vector2.distance(transform.position,target.position) > 200)
            {
                transform.position = Vector2.Movetowards(transform.position,target.position,speed * Time.deltaTime);
            }
else
{
// i want my enemy following my player with only Y coordinate right here,not moving forward anymore
}

解决方法

if (Vector2.Distance(transform.position,target.position) > 200)
{
    transform.position = Vector2.MoveTowards(transform.position,target.position,speed * Time.deltaTime);
}
else
{
    // i want my enemy following my player with only Y coordinate right here,not moving forward anymore
    transform.position = Vector2.MoveTowards(transform.position,new Vector2(transform.position.x,target.position.y),speed * Time.deltaTime);
}

,

Vector2结构具有两个位置分量：x和y。要沿y轴移动，请创建一个临时Vector2以存储变换后的位置，并仅复制y分量。

     Vector2 temporaryPosition = Vector2.MoveTowards(transform.position,speed * Time.deltaTime);
     if (Vector2.Distance(transform.position,target.position) > 200)
     {
         //copying the x and y position if the distance is greater than 200
         transform.position = temporaryPosition;
     }
     else
     {
         // copy the x position if the distance is below or equal to 200
         transform.position = new Vector2 (transform.position.x,temporaryPosition.y);
     }
