如何在只有1个坐标的情况下跟随我的玩家位置移动我的敌人

Question

我正在制作一个2d游戏，我遇到了一个问题，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。这是我在敌人脚本中的当前代码：

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y轴移动，请创建一个临时Vector2来存储转换后的位置，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);
}
