#includes (C++)

Hi all,

I'm trying to #include a class in several different classes, the problem is because these classes are all included into another, I get redefinition errors.

What I mean is:

Game.h #includes:
Material.h,
Terrain.h,
ParticleSystem.h

Terrain.h and ParticleSystem.h also both #include Material.h

Because of this I'm getting redefinition errors, how can I fix this so that all three can access Material? I know it's probably simple but I cant fix it.

Thanks!

Steven

 

you may have to include all the header files individually.
instead of doing

Code:

#include <Game.h>

you may have to do:

Code:

#include <Material.h>
#include <Terrain.h>
#include <ParticleSystem.h>
#include <whatever else is in Game.h>

know what i mean?

 

Try using #ifndef, #define, and #endif

Thanks Wyatt Earp, that's just the job!
