I am using MVS 2008. So here is the skinny. I created numerous classes each in http://www.cplusplus.com/forum/beginner/23825/ their own file. on 2 particular files BallManager.H and in PlayerManager.H i https://www.mathworks.com/matlabcentral/newsreader/view_thread/144487 have created a Vector containing objects of the type the managers are to manage. like so in BallManager.h vector AllBalls; in PlayerManager.h vector AllPlayers; i am able to pass by reference Allplayers from PlayerManager to Player with no problem so it can be used. example... in playerManager.cpp void error c2065 PlayerManager::Update(int ScreenWidth, int ScreenHeight, vector & AllBalls) { //calls update on all Players created for(int i=0; i &AllBalls gives error c2065 undeclared me the undefined Identifer error. how that came to be...... My main cpp file is called touchdemo. and it creates BOTH managers. I then at some given point i determined i needed the AllBalls Data to compare against the AllPlayers Data. So i passed the AllBalls Data via reference to the Update() function in PlayerManger. which in turn passes the vector via reference to the Update() for player. I thought the solution would be to include the Ball.h or BallManager.h in my PlayerManager.h file. so that it would know what ball was. however this only gives more errors and yet still keeps the old ones there saying its undefined identifier. anyone have any suggestions? im going to post below this one all the actual code so you can see.
