我使用Slick2D
和LWJGL
,我想问一个问题,当我运行它时,如何更改taskbar
中的游戏图标。
最佳答案
实际上,取决于您要精确执行的操作可能非常困难。
最简单的方法是使用Slick2d方法:在GameContainer中,您可以使用setIcon(String)方法。
但是在我的个人项目之一中,我在开始时使用Slick加载图像时遇到了一些困难。所以我用LWJGL寻找另一个解决方案:
public static void main(String[] args) {
AppGameContainer app;
try {
app = new AppGameContainer(new Main("Anode"));
org.lwjgl.opengl.Display.setIcon(loadIcon("resources/images/logo.png", app));
}
public static ByteBuffer[] loadIcon(String filepath,AppGameContainer app)
{
BufferedImage image = null;
try
{
image = ImageIO.read(app.getClass().getClassLoader().getResource(filepath));
}
catch (IOException e)
{
e.printStackTrace();
}
ByteBuffer[] buffers = new ByteBuffer[3];
buffers[0] = loadIconInstance(image, 128);
buffers[1] = loadIconInstance(image, 32);
buffers[2] = loadIconInstance(image, 16);
return buffers;
}
private static ByteBuffer loadIconInstance(BufferedImage image, int dimension)
{
BufferedImage scaledIcon = new BufferedImage(dimension, dimension, BufferedImage.TYPE_INT_ARGB);
Graphics2D g = scaledIcon.createGraphics();
double ratio = 1;
if(image.getWidth() > scaledIcon.getWidth())
{
ratio = (double) (scaledIcon.getWidth()) / image.getWidth();
}
else
{
ratio = (int) (scaledIcon.getWidth() / image.getWidth());
}
if(image.getHeight() > scaledIcon.getHeight())
{
double r2 = (double) (scaledIcon.getHeight()) / image.getHeight();
if(r2 < ratio)
{
ratio = r2;
}
}
else
{
double r2 = (int) (scaledIcon.getHeight() / image.getHeight());
if(r2 < ratio)
{
ratio = r2;
}
}
double width = image.getWidth() * ratio;
double height = image.getHeight() * ratio;
g.drawImage(image, (int) ((scaledIcon.getWidth() - width) / 2), (int) ((scaledIcon.getHeight() - height) / 2),
(int) (width), (int) (height), null);
g.dispose();
byte[] imageBuffer = new byte[dimension*dimension*4];
int counter = 0;
for(int i = 0; i < dimension; i++)
{
for(int j = 0; j < dimension; j++)
{
int colorSpace = scaledIcon.getRGB(j, i);
imageBuffer[counter + 0] =(byte)((colorSpace << 8) >> 24 );
imageBuffer[counter + 1] =(byte)((colorSpace << 16) >> 24 );
imageBuffer[counter + 2] =(byte)((colorSpace << 24) >> 24 );
imageBuffer[counter + 3] =(byte)(colorSpace >> 24 );
counter += 4;
}
}
return ByteBuffer.wrap(imageBuffer);
}
我真的建议您使用Slick2d解决方案,如果您达不到目标,则可以切换到更复杂的解决方案
