    <p>I'm currently trying to make a RPG game and I'm running into some trouble. This is the layout I have so far.</p> <p>Classes:</p> <ul> <li>Actor - Base class for anything that 'exists' such as units, projectiles, etc.</li> <li>Unit - Inherits Actor, basis for all units.</li> <li>Game - It will only have a single instance, and it'll contains pointers to all objects in the game. I plan to make it call a virtual function gameTick on all actors every 0.1 seconds.</li> </ul> <p>The problem I'm having is that I'd like all Actors to have a pointer to the Game instance. If I wanted to have a spell that does 500 radius area damage, I'd like Game to find and return all Unit pointers within that range.</p> <p>My problem is if I include Game in Actor's header file my program won't compile. How can I have my actors have access to Game? Or am I going about this the wrong way?</p> <p>Thanks in advance.</p> <pre><code>// START main.cpp #include &lt;iostream&gt; #include "game.h" int main() { std::cout &lt;&lt; "All done\n"; return 0; } // END main.cpp // START actor.h #ifndef __ACTOR_H_ #define __ACTOR_H_ #include &lt;iostream&gt; //#include "game.h" Causes many errors if uncommented class Actor { public: Actor(); std::string name_; }; #endif // END actor.h // START actor.cpp #include "actor.h" Actor::Actor() { name_ = "Actor class"; } // END actor.cpp // START unit.h #ifndef __UNIT_H_ #define __UNIT_H_ #include "actor.h" class Unit : public Actor { public: Unit(); }; #endif // END unit.h // START unit.cpp #include "unit.h" Unit::Unit() { name_ = "Unit class"; } // END unit.cpp // START game.h #ifndef __GAME_H_ #define __GAME_H_ #include &lt;vector&gt; #include "unit.h" class Game { public: std::vector&lt; Actor * &gt; actors_; std::vector&lt; Unit * &gt; units_; }; #endif // END game.h </code></pre>

    1. COWhat about thinking about breaking some things out into interfaces to fix dependency issues? I assume the errors you were getting had to do with circular dependencies.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
