c# - 将游戏对象缓慢移动到鼠标位置

Question

我想将对象的位置更改为鼠标的位置，从第一个位置缓慢移动到第二个位置。

我的物体正在缓慢地向随机方向移动，似乎与左下角相连。当我高于角落时，我的物体向上移动，左右相同。

using System.Collections.Generic;
using UnityEngine;

public class Rocket : MonoBehaviour
{
    public float speed = 10f;

    private Vector3 shippos;

    void Start()
    {
        shippos = transform.position;
    }

    void FixedUpdate()
    {
        if (Input.mousePosition.x > shippos.x)
            shippos.x=shippos.x+speed*Time.deltaTime;
        if (Input.mousePosition.x < shippos.x)
            shippos.x=shippos.x-speed*Time.deltaTime;
        if (Input.mousePosition.y > shippos.y)
            shippos.y=shippos.y+speed*Time.deltaTime;
        if (Input.mousePosition.y < shippos.y)
            shippos.y=shippos.y-speed*Time.deltaTime;
        transform.position = shippos;
    }
}

鼠标位置以屏幕空间坐标返回。您需要做的是将其转换为世界坐标，以便在与变换 (shippos) 相同的坐标空间中比较它们。

void FixedUpdate()
{
    if (Camera.main.ScreenToWorldPoint(Input.mousePosition).x > shippos.x)
        shippos.x = shippos.x + speed * Time.deltaTime;
    if (Camera.main.ScreenToWorldPoint(Input.mousePosition).x < shippos.x)
        shippos.x = shippos.x - speed * Time.deltaTime;
    if (Camera.main.ScreenToWorldPoint(Input.mousePosition).y > shippos.y)
        shippos.y = shippos.y + speed * Time.deltaTime;
    if (Camera.main.ScreenToWorldPoint(Input.mousePosition).y < shippos.y)
        shippos.y = shippos.y - speed * Time.deltaTime;
    transform.position = shippos;
}
