如何将PictureBox在TableLayoutPanel网格中从键盘上移动？
如何将PictureBox在TableLayoutPanel网格中从键盘上移动？
提问于 2015-12-30 20:53:24
我在C#很新，但我正在尝试移动一个picturebox，从键盘上按下左右键，在网格TableLayoutPanel中(我在运行时创建了网格)。网格为23x23，具有块图像边框(边框中的每个单元格都包含图像框中的块图像)和中间有鼠标的图像框。我要做的是通过按上面提到的一个控制键，将鼠标图像从中央单元格( 11x11)移动到另一个单元格中。似乎我无法控制eventHandler的想法.。在我想让picturebox移动之前，代码运行得很好。我已经将整个代码放到了一个我没有注意到的地方，但我认为问题是KeyDown += new KeyEventHandler(Form2_KeyDown)或/EndPrivatevoidForm2_KeyDown(对象发送方，KeyEventArgs e){.}。

每次按一下键，你总是将起始位置设置为11，11。将声明移出该范围：
int x = 11, y = 11;

以下是移动鼠标的一种非常简化的方法，我直截了当地把事情降到最低，但效果很好:D
下面是我用过的瓷砖：
这是密码！
using System;
using System.Collections.Generic;
using System.Drawing;
using System.Windows.Forms;
namespace WindowsFormsApplication3
{
public partial class Form1 : Form
{
private Dictionary<int, Image> _dictionary;
private Size _imageSize;
private int[] _level;
private Size _levelSize;
private Point _mousePos;
public Form1()
{
InitializeComponent();
pictureBox1.Paint += PictureBox1_Paint;
}
private void Form1_Load(object sender, EventArgs e)
{
InitializeLevel();
Redraw();
}
private void InitializeLevel()
{
var imageEmpty = Image.FromFile("empty.png");
var imageMouse = Image.FromFile("mouse.png");
var imageWall = Image.FromFile("wall.png");
_level = new[]
{
0, 0, 0, 0, 0,
0, 1, 1, 1, 0,
0, 1, 1, 1, 0,
0, 1, 1, 1, 0,
0, 0, 0, 0, 0
};
_levelSize = new Size(5, 5);
_imageSize = new Size(25, 25);
_dictionary = new Dictionary<int, Image>();
_dictionary.Add(0, imageWall);
_dictionary.Add(1, imageEmpty);
_dictionary.Add(2, imageMouse);
_mousePos = new Point();
}
private void Redraw()
{
pictureBox1.Invalidate();
}
private void PictureBox1_Paint(object sender, PaintEventArgs e)
{
var graphics = e.Graphics;
graphics.Clear(Color.Transparent);
// draw level
var i = 0;
foreach (var tile in _level)
{
var x = i % _levelSize.Width;
var y = i / _levelSize.Width;
var image = _dictionary[tile];
graphics.DrawImage(image, new Point(x * _imageSize.Width, y * _imageSize.Height));
i++;
}
// draw hero !
graphics.DrawImage(_dictionary[2], _mousePos);
}
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
var up = keyData == Keys.Up;
var down = keyData == Keys.Down;
var left = keyData == Keys.Left;
var right = keyData == Keys.Right;
var processed = up || down || left || right;
if (!processed) return base.ProcessCmdKey(ref msg, keyData);
// move the hero !
var x = 0;
var y = 0;
if (left) x--;
if (right) x++;
if (up) y--;
if (down) y++;
_mousePos.X += x;
_mousePos.Y += y;
Redraw();
return true;
}
}
}很明显你还是想检查碰撞，定义你的逻辑等等.
继续试一试！
欢迎光临，祝您好运:D
