^这是我的主要课程[// Font.render（＆＃34; Hello Wolrd！0157＆＃34;，screen，0,0，Colours.get（000，-1，-1,555））; ]＆lt;这是我得到错误的地方......
package aaron.game.gfx;
public class Font {

public static void render(String msg, Screen screen, int x, int y, int colour, int scale) {

if (charIndex >= 0) screen.render(x + (i * 8), y, charIndex + 30 * 32, colour, false, false);
}

这是阅读我的字体的课程

if(col<255) pixels[(x+xPos)+(y+yPos)*width]=col;
}
}
}
}
这是我的展示类，无论如何这个错误正在扼杀我，我不知道如何解决它，我已经把地方机器人看了一个地方，我得到的错误是
Font类型中的方法render（String，Screen，int，int，int，int）不适用于参数（String，Screen，int，int，int）
答案 0 :(得分：0)
尝试清理和重建项目。似乎该程序的旧版本正在运行...
