Weapons intialization

I have just finished defining and prototyping my weapons for my game. When I got to test it in a generic main file, it won't compile. Most of it is declared void and that causes some problems for some reason. Also, it says some of my class types name no type. 


class GWeapon
{
    protected:
       unsigned int m_ammo;
....

class Rifle : public GWeapon
{
   public:
     ...
     static Rifle fireRate;
     void Rifle wDamage;
};

...
I am wondering why it is doing this...can anyone help me?

Thanks Anon. I got it to work last night and now I'm working on the .cpp file. I was wondering if anyone could show me how I would implement the functions? I think I need to do Pistol::particlePistol( functions) and then go into what it should do, initialize the damage and whatnot. Any have any links or thoughts about how I am supposed to do that?

what do you mean by implement the functions?
<ClassName>::<FunctionName>(<Argument1>, <Argument2>, ... )
{

}

do you mean that stuff or are you not shure what variables you need for your weapon?

That stuff. :) I know most of the variables I'm going to need. I wasn't sure on how I would go about doing it. When I try to compile it in a dummy program, to make sure it's all declared and set up right, I get errors. I'll edit this once I get the errors and you can see what I mean. DO you know of any sites or articles I could read that would help me do this? I have to add my player.h/.cpp class in the header once I get it done and I also need the player to be able to shoot the weapons. I know the variables and methods I want to use to get that situated but I just need to see how I am supposed to go about it. How would I make sure no errors are in there?


EDIT: Here is the full .h code for the weapons. I know there are some errors here. Could you tell me a better way to do it?

why do you try to instance an object of the same class within that class declaration? i don't get it.

class xyz
{
public:

xyz MyFunction();

...

};

doesn't make ANY sense. are you trying to create a constructor / destructor there? in that case you just need to type xyz(); for the constructor and ~xyz() for the destructor.

to declare a function within a class, you just need to do the same as if the function were out the class:

int myfunc();

class blub
{
int myfunc() { some code }
bool secondfunc();
};

you need to do this:

bool blub::secondfunc()
{

}

if you've just declared the function header in the class and the code is somewhere else ( most likely in the cpp file )

perhaps you should consider buying a book about c++ and especially classes: they're not so hard, after you're in them. it takes some time, but this is basic stuff and in my point of view c++ makes much more fun with 'em. :)

i've searched on the net, google will spit out several tutorials about classes:

http://www.cplusplus.com/doc/tutorial/classes.html

this is just the first result for: 'c++ classes tutorial'
you should put effort in this section of c++, i love to play around with classes ^^

uh-oh
#include "Log.cpp"


Are you sure about that dude ? ;) Unless you excluded Log.cpp from the build (talking in VC++ words) you may get serious complaints form you compiler. Didn't you mean to include Log.h instead ?

Wish you good luck

Thanks everyone. I've gone back and edited my code to include the help and fixes you've all gave me.

Janta - I did mean .h so that is also fixed. After reading that I tried to instance inside the class which should be handled in the .cpp file, I feel amazingly, enormously idiotic. Sorry folks. I'm getting back into programming and I figured I would jump right in and learn from my mistakes. You've all made this reimmersion so much more easier.

.cpp: This is just messing around, getting things in there and trying to compile the code. Nothing is working and when you try to compile the two, you'll see the errors I get...their confusing me
//GWeapon.cpp#include "gweapon.h"class Pistol : class GWeapon;Pistol::particlePistol(float pShellLength, int pLaserPower, int Charge, int Fire, int wDamage, int Reload){    float particleShellLength = 1;    int particleLaserPower = 3;    int Charge = particleLaserPower + 3;    int wDamage = particleLaserPower;    int Reload;}Pistol::~particlePistol(){};Pistol::pulsePistol(float pShellLength, int pLaserPower, int Charge, int Fire, Pistol wDamage, Pistol Reload){    float pShellLength = 1.3;    int pLaserPower = 4;    int Charge = pLaserPower + 3;    Pistol wDamage = pLaserPower;    Pistol Reload;}Pistol::~pulsePistol(){};Pistol::bePistol(float pShellLength, int pLaserPower, int Charge, int Fire, Pistol wDamage, Pistol Reload){    float pShellLength = 1;    int pLaserPower = 3;    int Charge = pLaserPower + 3;    Pistol wDamage = pLaserPower;    Pistol Reload;}Pistol::~bePistol(){};Pistol::sonicPistol(float pShellLength, int pLaserPower, int Charge, int Fire, Pistol wDamage, Pistol Reload){    float pShellLength = 1.5;    int pLaserPower = 3;    int Charge = pLaserPower + 3;    Pistol wDamage = pLaserPower;    Pistol Reload;}Pistol::~sonicPistol(){};



I appreciate the help and anything else you all are able to provide me. I am just messing around with the .cpp file but when I try to compile and correct the errors it gives me, they don't seem to go away or anything...I think I'm just messing something up.....

EDIT: Also, I wanted to know if you knew any good algorithm sites I could look at and learn from. I want to try my fire and reload functions but I can't seem to get around the firing and reloading the ammo and all that.
