我需要在其他類的粒子中包含兩個類：Maze和Screen。我需要他們來實現moveEast操作。 迷宮是一個隨機生成的迷宮和屏幕有我要畫人物的屏幕的分辨率。我使用的是opengl和glut。在另一個類中使用類

};
的錯誤信息是：
../Particle.h:44:25: error: ‘Screen’ has not been declared
void moveEast(Maze m, Screen s);
^
make: *** [Ghost.o] Error 1
的想法是，我有稱爲米（迷宮）這些全局變量，S（屏幕）和p（吃豆子，這是另一種類），在main.cpp中。編號需要調用moveEast操作類似於：
Maze m;
Screen s;
Pacman p;
p.moveEast(m,s);
另外我把聲明部分的主要文件。
的main.cpp
#include "Maze.h"

任何想法將apreciated。
我們可以看到的內容maze.h，screen.h？你有沒有在這兩個中包含particle.h？如果你在屏幕或迷宮的類定義中使用了粒子對象，那麼你有一個雙重包含，這將是你的問題的原因？ – Dese
什麼是'Screen'聲明？ particle.h能看到它嗎？它可能在命名空間嗎？ – Unimportant
看起來像編譯文件Ghost.cpp時遇到問題，所以我認爲我們需要看到的是您的Ghost.h/.cpp –
