Question

我使用TranslateTransition将ImageView从中移出到舞台窗口的中心。这是问题：动画跳跃。 ImageView的运动不是平滑和线性的。我尝试启用-Dcom.sun.scenario.animation.vsync=true, -Dcom.sun.scenario.animation.adaptivepulse=true属性，但没有成功。认为这些问题可能是由于PC的功能，我运行应用程序更强大和不同的PC（I7与16GB的RAM），但再次没有成功，动画不顺利。我读到JavaFX定时器根据屏幕hz自动计算脉冲。那么你可以帮我解决动画不顺畅的原因吗？

尝试在节点（图片）上设置缓存和 cacheHint 以获得流畅的动画效果，即

 node.setCache(true);
 node.setCacheHint(CacheHint.SPEED);
