相关疑难解决方法(0)

我(我认为是)JFrame的直接BufferStrategy.它是这样创建的:

    // Buffer
    container.createBufferStrategy(2);           
    strategy = container.getBufferStrategy();

但是,偶尔我收到以下错误(指向前一个片段的第一行作为违规项目):

java.lang.IllegalStateException:尚未创建缓冲区

这个错误很奇怪,因为它来来去去 - 有时它被触发,有时不会触发.我怀疑这意味着它是一个线程问题.有没有人对这里可能发生的事情有任何指示？我有点不知所措,因为我已经在尝试做Java希望我做的事情了!
