Unity

参考：[Unity2D]在2D游戏里面实现人物的移动[消除抖动]https://blog.csdn.net/Z_hongli/article/details/115664222

脚本：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Move : MonoBehaviour
{
    private float horizontal;
    private float vertical;
    public float MoveSpeed=3;

    void Start()
    {
    }

    void Update()
    {
        float h = Input.GetAxis("Horizontal");
        float v = Input.GetAxis("Vertical");
        Vector2 position = transform.position;
        position.x = position.x + MoveSpeed * h* Time.deltaTime;
        position.y = position.y + MoveSpeed * v* Time.deltaTime;
        transform.position = position;
    }
}

引擎默认是WASD移动Horizontal和Vertical

这种是相对于世界场景坐标系的横平竖直的移动方式
