该事件对于游戏来基本上没有使用,所以我们只关注键盘的press和release事件。 以上方法都有一个KeyEvent事件参数,该事件对象可以让我们观察哪个键盘被按下和释放掉—使用虚拟键盘代码(virtual key code)。 虚拟键盘是Java定义的代码,用来表示每个键盘的键,但是它不与实际的字符相同,比如Q和q是不同字符,但是它们有相
StringBuilder barcode = new StringBuilder(); @Override public void nativeKeyPressed(NativeKeyEvent e) { char keyChar = NativeKeyEvent.getKeyChar(e.getKeyCode()); if (keyChar != '\0') { // Ignore null characters barcode.append(keyChar); } if (keyChar == ' ') { // Detect enter ke...
Native memory leaks: associated with any continuously growing memory utilization that is outside the Java heap, such as allocations made by JNI code, drivers or even JVM allocations. In this memory management tutorial, I’ll focus on Java heaps leaks and outline an approach to detect such leaks...

此外,模型结合了GFL(generalized focal loss)损失计算策略,将Detect模块由YOLOv5中的耦合头改进成解耦头,如图所示。解耦头将分类任务和回归任务分开进行,避免了两个任务之间的干扰,理论上能够提高模型的训练效率。传统的YOLO系列算法的耦合头输出三类信息,而YOLOv8模型中的解耦头仅输出分类和回归信息。分类信息的输出通道...

If set to true (the default) then IA-Connect Agent will attempt to automatically detect the 'click' action name in non-English locales. If there are more than two possible actions for the element then the 'Override action name' will be used. If set to false then IA-Connect Agent will ...
