Thread: Calling an object in a function

I have had this problem which i keep coming back to, and i have to solve it somehow now

My Main function:

Code:

void main(){
Character Luke;
Luke.initialise;

battle();
}

My class:

Code:

class Character
{
 public:
    void initialise();
    int get_hp();
 private:
    int hp;

My function:

Code:

void battle(){
  Luke.get_hp();
};

however i get the nice problem that "Luke is undeclared in this function" (the 'battle' function).
I of course have several other functions which need to access "Luke.get_hp();" and other modules that i have in the class. So how can i get the "battle" function to be able to see that i have already created the object "Luke" and allow access to it?

btw, i think i need to somehow make the classes have a global scope. but i really cant think of a way to do that...

Why don't you just pass the object into the function? Try this for the new prototype.

Code:

void Battle( const Character &temp )
{
     temp.get_hp( );
}

Also in your main you call initialize without paranthesis. You need these because it is a function, remember.

Remove the const keyword...

It's better to pass the address of the Character object to the function:

Code:

void battle(Character *C)
{
  C->get_hp();
}

In main:

battle(&Luke);
