如何仅用 1 个坐标跟随我的玩家位置来移动我的敌人

Question

我正在制作一个 2d 游戏，我被卡住了，我希望我的敌人只用 Y 坐标跟随我的玩家，这意味着如果我的玩家向上或向下移动，敌人会跟随但不会向前移动. 这是我当前在 Enemy Script 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
}

Answer 1

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);
}

Answer 2

Vector2 结构有两个位置分量：x 和 y。要沿着 y-axis 移动，请创建一个临时 Vector2 来存储变换后的位置并仅复制 y 分量。

     Vector2 temporaryPosition = Vector2.MoveTowards(transform.position, target.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);
     }
