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
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。
This code should be adapt to your purpose.
