Java 渲染字体后fps突然下降
所以我正在做一个简单的侧滚游戏,比如flappy bird,当我添加音乐和所有精灵时,游戏运行得很顺利。但是当我添加字体(ttf)时,游戏的fps突然下降,并且落后了很多。 需要帮忙吗 以下是我的渲染方法:Java 渲染字体后fps突然下降,java,performance,libgdx,frame-rate,Java,Performance,Libgdx,Frame Rate,所以我正在做一个简单的侧滚游戏,比如flappy bird,当我添加音乐和所有精灵时,游戏运行得很顺利。但是当我添加字体(ttf)时,游戏的fps突然下降,并且落后了很多。 需要帮忙吗 以下是我的渲染方法: @Override public void render(SpriteBatch sb) { sb.setProjectionMatrix(cam.combined); sb.begin(); sb.draw(actualGamebg, cam.position.

如果你需要更多信息,一定要告诉我,谢谢。
干杯您正在读取ttf文件并每帧创建一个新的BitmapFont对象。不要在update()中调用fontGenerator()。在构造器中调用一次。谢谢,它成功了,游戏现在看起来好多了。如果你看到任何优化,你能建议代码中的其他优化吗?
