我正在尝试将游戏的图像绘制到C#中的Panel上。我没有得到任何图像,我无法弄清楚为什么这个方法永远不会被调用:
private void playerPanel_Paint(object sender,PaintEventArgs e)
这是我的代码:
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 FlightOfTheNavigator
{
public partial class Form1 : Form
{
// Load Sprites
public Bitmap playerShip = new Bitmap(FlightOfTheNavigator.Properties.Resources.testship);
public Form1()
{
InitializeComponent();
SetupGame();
}
public void SetupGame()
{
// Setup Console
txtConsole.Text = "Loading Ship Bios v3.4.12c ..." +
Environment.NewLine +
"Console Ready" +
Environment.NewLine +
"----------------------------------------------------------------------------------------" +
Environment.NewLine +
Environment.NewLine;
// Setup Basic Weapons
listWeapons.Items.Add("Pulse Lazers");
listWeapons.Items.Add("Cluster Missiles");
// Set Shield Perecentage
txtShields.Text = "0%";
}
private void trackShield_Scroll(object sender, EventArgs e)
{
txtShields.Text = "" + trackShield.Value + "%";
}
private void playerPanel_Paint(object sender, PaintEventArgs e)
{
Graphics g = playerPanel.CreateGraphics();
g.DrawImage(playerShip, 0, 0,100,100);
}
private void button1_Click(object sender, EventArgs e)
{
// Invalidate the panel. This will lead to a call of 'playerPanel_Paint'
playerPanel.Refresh();
}
}
}

确保面板的Paint
事件附加到playerPanel_Paint
方法。
打开Desinger,选择面板(playerPanel
),按 F4 打开“属性”窗口,然后单击“属性”窗口上方的闪电以显示事件。检查那里的Paint
事件。如果为空,请打开下拉列表并选择playerPanel_Paint
方法。
您也可以在代码中执行此操作。在InitializeComponent()
之后将其放入表单的构造函数中:
this.playerPanel.Paint += PaintEventHandler(playerPanel_Paint);
