我的代码根本不会使用tmrMoving
(定时器),即使定时器持续打开,间隔值为100,所以没有理由我可以看到,但我希望它和&#m} #39;这只是其中的一天而且很简单。代码如下,
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Globalization;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace games1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_MouseDown(object sender, MouseEventArgs e)
{
tmrMoving.Enabled = true;
Invalidate();
}
private void tmrMoving_Tick(object sender, object value, Type targetType,
object parameter, CultureInfo culture, EventArgs e)
{
var cursPoint = new System.Drawing.Point(Cursor.Position.X, Cursor.Position.Y);
var playerPoint = new System.Drawing.Point(player.Location.X, player.Location.Y);
var diff = new Point(Cursor.Position.X - playerPoint.X, Cursor.Position.Y - playerPoint.Y);
var speed = Math.Sqrt(diff.X * diff.X + diff.Y * diff.Y);
if (speed > 10)
{
diff.X /= (int)(speed / 10);
diff.Y /= (int)(speed / 10);
}
player.Location = new System.Drawing.Point(player.Location.X + diff.X, player.Location.Y + diff.Y);
}
}
}
如果你喜欢这样的话,这个链接就是我的coding图片格式。
答案 0 :(得分:1)
在我看来,你有两个问题:
您的事件处理程序签名与what I expected it to be不匹配。我原以为:
private void tmrMoving_Tick(object sender, EventArgs e)
无法使用附加到事件的已损坏事件处理程序进行编译。因此在我看来它根本没有分配。检查代码是否存在(可能在Designer.cs
文件中):
this.tmrMoving.Tick += tmrMoving_Tick;
