在面板c中移动图像＃ [英] Move image inside panel c#

问题描述

您好，我正在尝试在面板控制中移动一个图像。

我有背景图片：

加载事件：

panel1。 BackgroundImage = img;

和图片：

绘制事件：

e.Graphics.DrawImage（img_player，new Point（0,0）） ;



如何从key_down事件发送int变量到paint事件并添加这样的代码

e.Graphics.DrawImage（img_player） ，新点（0 + x，0 + y））;如何发送x和y变量？

Hello, i am trying to move an Image inside panel controle.
I have background image:
load event:
panel1.BackgroundImage = img;
and Image:
paint event:
e.Graphics.DrawImage(img_player, new Point(0, 0));

How can i send int variable from key_down event to paint event and add code like this one
e.Graphics.DrawImage(img_player, new Point(0+x, 0+y)); how can i send x and y variable?

private void Form1_KeyDown(object sender, KeyEventArgs e)
       {
           if (e.KeyData == Keys.Up)
           {
               int x = 10;
               int y = 0;

           }
and etc key.down,key.left,key.right same thing just x and y will be different..

img和img_player是全球性的：

图片img = Image.FromFile（@D：\C＃\ Lavirint \\ \\ lavirint\images\map1.png）;

图片img_player = Image.FromFile（@D：\C＃\ Lavirint \ Lavirint \images \ player.png ）;

img and img_player are global:
Image img = Image.FromFile(@"D:\C#\Lavirint\Lavirint\images\map1.png");
Image img_player = Image.FromFile(@"D:\C#\Lavirint\Lavirint\images\player.png");

推荐答案

使用X和Y作为类的成员在KeyDown事件中更新它们，并使刚刚绘制图像的控件无效。

Use X and Y as member of your class update them in the KeyDown event and invalidate the control that paint the image just after.

private void Form1_KeyDown(object sender, KeyEventArgs e)
{
  if(e.KeyData == Keys.Up)
  {
    x=10;
    y=0;
    imgCtrl.Invalidate();
  }
}
private void imgCtrl_OnPaint(object sender, PaintEventArgs e)
{
  e.Graphics.DrawImage(img_player, new Point(x,y));
}

此代码应适应您的目的。
