To put it short, arrays do not do the best job in my situation, tried to switch one aspect of my game over to classes, don't work, get these errors when I try to compile

fat errors:

yeah those were like the compiller kicking me in the face.

Here is the class:

+ Code Snippet

class tplayer {
public:
	int ModelNumber = 3;
	int health = 100;
	int level = 1;
	int attack = 15;
	int defence = 20;
	int LastAttackTime = 0;
	int SelectedNPC = -1;
	bool CanAttack = true;
	char name = "sucka fish";

	void Can_Attack ( int curtime )
	{
		if ( curtime >= LastAttackTime )
		{
			CanAttack = true;
		}
	}

	int Attack ( int curtime )
	{
		if ( CanAttack == true )
		{
			LastAttackTime = curtime;
			CanAttack = false;
			npcs[SelectedNPC][1] = npcs[SelectedNPC][1] - 10;
			return 10;
		}
	}
};

And here are the various areas i'm trying to use it:

+ Code Snippet

	if ( dbSpaceKey() == 1 ) 
	{
		if ( player[6] == 1 && player[7] > -1 )
		{
			//Attack_Function(player[7]);
			tplayer::Attack ( seconds );
		}
	}

+ Code Snippet

	if ( dbMouseClick() == 1 )
	{
		int selobj = dbPickObject(dbMouseX(),dbMouseY(),1,1000);
		i = 0;
		strcat ( stuff19, dbStr ( selobj ) );
		dbText ( 0, 50, stuff19 );
		if ( selobj >= 500 && selobj <= 1000 )
		{
			//player[7] = selobj-500;
			tplayer::SelectedNPC = selobj-500;
		}
		else
		{			
			//player[7] = -1;
			tplayer::SelectedNPC = -1;
		}
	}

+ Code Snippet

	while ( LoopGDK ( ) )
	{		
		seconds = time ( 0 );
		tplayer::Can_Attack ( seconds );
		//Player_Update ( );
		//Net_Messages ( );
		//Net_Send ( );
		Camera_Control ( );
		Player_Control ( );
		Screen_Print ( );
		moveObject ( 3, 0 );
		Sprite_GUI ( );
		NPC_Respawner ( );
		dbSync ( );
	}

I've read multiple tutorials on classes, I cant even use '.''s to access my variables.

I just dont get it...

You have to initialize values of the class in the constructor, you can't just define and initialize at the same time in a class. Example:

+ Code Snippet

class myClass {

      protected:
                 int myVar1;
                 bool myVar2;
                 float myVar3;
                 char* myOutput;
                 ~myClass() { delete[] myOutput; } // Destructor
                 // etc

      public:
              myClass (int, bool, float); // Constructor, use this to initalize variables
              int myFunc1(); 
              bool myFunc2();
              // etc;

}

// Now use the constructor to initialize the variables:

myClass::myClass (int a, bool b, float c) {
         
         myVar1 = a;
         myVar2 = b;
         myVar3 = c;
         // Etc, you do not have to ask for input on every var, ex:
         myOutput = "Return or output this message, destructor will delete it after any function";
}

In your main program you would call something like this:

+ Code Snippet

myClass *mC = new myClass (5, true, 3.14); // Call the constructor once in your main program

// Now you call your functions like this:

mC->myFunc1(); // And so on.

It would be retrun before myOutput... correct?

+ Code Snippet

myClass::myClass (int a, bool b, float c) {
         
         myVar1 = a;
         myVar2 = b;
         myVar3 = c;
         // Etc, you do not have to ask for input on every var, ex:
         return myOutput = "Return or output this message, destructor will delete it after any function";

Quote: "LP->CanAttack
LP->attack"

CanAttack and attack are private members of the class. In order to access them you need to use a public member function to get/set the values. Otherwise, you can set the data to public.

I think you may be trying to access the functions Can_Attack and Attack. If so, that's not what you're actually requesting.

You may have the same problem with over variables in the class.

I made all the variables public

but still:

I'm just trying to create a simple player class to be the object for my player and hold all its variables and related functions.. I think i'm missing something about classes because what i'm doing, to me, looks logically correct. -_-*

You're trying to call the integer and bool as if they were functions. Are you trying to get/set these variables or are you trying to call the functions Can_Attack and Attack? You're showing

LP->attack (second)

That's a function call. attach is not a fucntion. It's a variable.

I'm not sure what the problem is with the identifier "Initialize". I'm guessing that you have something with that identifier in another .h file and would have to look there to find the problem.

I'm trying to call the functions, Attack is a function attack is a variable capital difference on the a's

The identifier is unique...

Change your code to the above.

Do you have a header file called "declarations.h"? Look there for Initialize

okay.. but.. if.. I'll try and move it elsewhere. I thought that was where it was supposed to be..

Intialize isn't a class, it's a class member. What you want to do is

tplayer *LP = new tplayer; //
LP->Initialize();

This says

declare a pointer to type tplayer called LP, create a new tplayer object somewhere in the system and return the address of that object so I can assign it to my pointer.

The next step says to use the pointer to the object to run the Initialize() function in that class.
