我正在写一个简单的游戏 - 蛇。我想要背景和我的蛇。我认为最好的方法是使用两个pictureBox(一个带背景,第二个 - 透明带蛇)。
这是一个好方法吗?我怎样才能将几个小图像(蛇形片段)放在不同位置的一个图片盒上(只是将像素(一个接一个)从图像复制到pictureBox,或者可能有最快的方法 - 将所有图像放在正确的位置)?我现在有带背景(父母)和另一个透明(儿童)的pictureBox。
结果应该是这样的:
我做过类似的事情(感谢@dotTutorials),但是我的蛇的片段比原始图片大一点,而cookie更小。哪里可能有问题?
绘图代码:
public Bitmap PrinPlayground()
{
char[,] tempPitch = play.getPitch();
Graphics g = pb2.CreateGraphics();
Bitmap bitmap = new Bitmap(512, 512);
Graphics BBG = Graphics.FromImage(bitmap);
Bitmap head = CookieSnake.Properties.Resources.head;
Bitmap body01 = CookieSnake.Properties.Resources.body01;
Bitmap tail = CookieSnake.Properties.Resources.tail;
Bitmap cookie = CookieSnake.Properties.Resources.cookie;
BBG.Clear(Color.Transparent);
for (int i = 0; i < 16; i++)
for (int j = 0; j < 16; j++)
{
if (tempPitch[i, j] == 'H')
{
BBG.DrawImage(head, new Point(32*j, 32*i));
}
else if (tempPitch[i, j] == 'B')
{
BBG.DrawImage(body01, new Point(32*j, 32*i));
}
else if (tempPitch[i, j] == 'T')
{
BBG.DrawImage(tail, new Point(32 * j, 32 * i));
}
else if (tempPitch[i, j] == 'C')
{
BBG.DrawImage(cookie, new Point(32 * j, 32 * i));
}
}
g.DrawImage(bitmap, new Point(0,0));
return bitmap;
}
结果:
答案 0 :(得分:4)
实现这一目标的最佳方法是使用'Graphics'类。请进一步查看GDI和名称空间System.Drawing
。
如果您想使用代表游戏空间的Picturebox,您也可以通过调用成员CreateGraphics
轻松地将图形实现到图片框。
我希望这会对你有所帮助! :) 请注意,当您进入严肃的游戏开发时,您必须找到比GDI更好的选择。我个人更喜欢XNA库
GDI的示例用法[这写得很快,不应该复制粘贴。然而;这是一个很好的起源点:)]
Graphics g = pictureBox1.CreateGraphics();
Bitmap BB = new Bitmap(pictureBox1.Width, pictureBox1.Height);
Graphics BBG = Graphics.FromImage(BB);
Bitmap Background = (Bitmap)Bitmap.FromFile("BackgroundPicture.png");
Bitmap Head = (Bitmap)Bitmap.FromFile("SnakeHead.png");
Bitmap Tail = (Bitmap)Bitmap.FromFile("SnakeTail.png");
Point snakeLocation = new Point((BB.Width / 2) - (Head.Width / 2), (BB.Height / 2) - (Head.Height / 2));
while (true) {
#region Update
// update method here!
snakeLocation.X += 1;
#endregion
#region Draw
BBG.Clear(Color.CornflowerBlue);
BBG.DrawImage(Background, new Point(0, 0));
BBG.DrawImage(Head, snakeLocation);
BBG.DrawImage(Tail, new Point(snakeLocation.X - Head.Width, snakeLocation.Y));
g.DrawImage(BB, new Point(0, 0)); // draw to screen
#endregion
}
UPDATE: DrawImage方法也接受RectangleF输入。 RectangleF由4种数据类型组成,float X,float Y,float Width和float Height。
使用RectangleF,您可以轻松指定绘制图像的大小。看看下面的代码:
public Bitmap PrinPlayground() {
char[,] tempPitch = play.getPitch();
Graphics g = pb2.CreateGraphics();
Bitmap bitmap = new Bitmap(512, 512);
Graphics BBG = Graphics.FromImage(bitmap);
Bitmap head = CookieSnake.Properties.Resources.head;
Bitmap body01 = CookieSnake.Properties.Resources.body01;
Bitmap tail = CookieSnake.Properties.Resources.tail;
Bitmap cookie = CookieSnake.Properties.Resources.cookie;
BBG.Clear(Color.Transparent);
for (int i = 0; i < 16; i++)
for (int j = 0; j < 16; j++) {
if (tempPitch[i, j] == 'H') {
BBG.DrawImage(head, new RectangleF(new Point(32 * j, 32 * i), new SizeF(/*Adjust the size after your pleasure*/32, 32)));
}
else if (tempPitch[i, j] == 'B') {
BBG.DrawImage(body01, new RectangleF(new Point(32 * j, 32 * i), new SizeF(32, 32)));
}
else if (tempPitch[i, j] == 'T') {
BBG.DrawImage(tail, new RectangleF(new Point(32 * j, 32 * i), new SizeF(32, 32)));
}
else if (tempPitch[i, j] == 'C') {
BBG.DrawImage(cookie, new RectangleF(new Point(32 * j, 32 * i), new SizeF(/*Half the size of the head [Adjust after your needs!]*/32 / 2, 32 / 2)));
}
}
g.DrawImage(bitmap, new Point(0, 0));
return bitmap;
}
}
