我想知道为什么代码在移动计数达到10时出现故障。有人可以帮我确定导致错误的原因以及如何修复错误吗？我一直在想，因为它所做的一切都是计算它到达10时会出现故障。

更改“Text”的构造函数（即countText），如下所示
countText = new Text(0, 0, main_font, "Moves:" + movesCount , 10, this.getVertexBufferObjectManager());
countText.setPosition(0,0);
scene.attachChild(countText);

最初，您必须设置countText最大缓冲区大小。以下列方式更改countText初始化
countText = new Text(0, 0, main_font, "Moves:0123456789" , this.getVertexBufferObjectManager());
countText.setText("Moves:" + movesCount");
countText.setPosition(0,0);
scene.attachChild(countText);
