移动播放器时出现峰值滞后 [英] Lag spike when moving player
问题描述
播放器是一个面板,将其删除,将其位置更改,然后重新添加到绘制到主框架的另一个面板(包含此方法的面板)中.还有许多其他小的面板,其中包含草精灵作为地形图块绘制到主面板上.我认为问题在于,当我调用revalidate()
时,它也会重新验证所有这些小面板.我该如何解决?
The player is a panel, and it is getting removed, its position changed, and then re-added to another panel (which is what contains this method) which is drawn to the main frame. There are also a lot of other small panels containing a grass sprite being drawn to the primary panel as terrain tiles. I think the problem is that when I call revalidate()
, it revalidates all those little panels as well. How can I solve this?
我应该提到我正在使用RelativeLayout
将播放器放置在主面板上.
I should mention that I am using RelativeLayout
to position the players on the primary panel.
private class MainKeyAdapter extends KeyAdapter {
@Override
public void keyPressed(KeyEvent evt) {
// TODO add your handling code here:
if(AttentionedPlayer != null)
{
if (evt.getKeyCode() == KeyEvent.VK_UP) {
AttentionedPlayer.Ypos -= 16;
}
if (evt.getKeyCode() == KeyEvent.VK_DOWN) {
AttentionedPlayer.Ypos += 16;
}
if (evt.getKeyCode() == KeyEvent.VK_LEFT) {
AttentionedPlayer.Xpos -= 16;
}
if (evt.getKeyCode() == KeyEvent.VK_RIGHT) {
AttentionedPlayer.Xpos += 16;
}
remove(AttentionedPlayer);
AttentionedPlayer.movePlayer();
System.out.println("!!!!"+AttentionedPlayer.constraints.toString());
add(AttentionedPlayer, AttentionedPlayer.constraints, AttentionedPlayer.Zpos);
AttentionedPlayer.revalidate();
}
}
}
推荐答案
AttentionedPlayer.movePlayer();
似乎是一项繁琐的操作,您可以在 SwingWorker执行.
AttentionedPlayer.movePlayer();
seems to be an intensive operation, and you execute it from within EDT (the GUI thread). Instead, execute it from within a new thread or a SwingWorker.
