如何在Windows窗体中使用C＃移动播放器

Question

本学期的项目是一款游戏，但是您将使用Windows Form而不是unity ...我实际上制作了一个游戏，但是播放器仍在继续移动...我想要的是当我按下播放器时只会移动不连续的1个图块...顺便说一句，我们分配做的游戏是Bomber man，如果有人有可以与您共享的资源，我希望您能与我共享...这是我已使用：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace StudyControl
{
    public partial class FormView : Form
    {   
        enum Position
        {
            Left, Right, Up, Down
        }
        private int _x;
        private int _y;
        private Position _objPosition;



        public FormView()
        {
            InitializeComponent();

            _x = 50;
            _y = 50;
            _objPosition = Position.Down;
        }

        private void FormView_Paint(object sender, PaintEventArgs e)
        {
            e.Graphics.DrawImage(new Bitmap("Character.png"), _x, _y, 100, 100);
        }

        private void TmrMoving_Tick(object sender, EventArgs e)
        {

            Invalidate();
        }

        private void FormView_KeyDown(object sender, KeyEventArgs e)
        {
            if(e.KeyCode == Keys.Right)
            {
                _x += 100;
                _objPosition = Position.Right;
            } else if (e.KeyCode == Keys.Left)
            {
                _x -= 100;
                _objPosition = Position.Left;
            } else if (e.KeyCode == Keys.Up){
                _y -= 100;
                _objPosition = Position.Up;
            } else if (e.KeyCode == Keys.Down){
                _y += 100;
                _objPosition = Position.Down;
            }
        }
    }
}
