Damn! I noticed that just before you posted and was hoping I could change it in time! How embarassing lol sorry

Hi,

I have a global variable
Game * game;

in main I have game = new Game();

and I have another function which monitors the progress of the game and if the current level is completed then I...

Thank you everyone for your ideas. I ended up doing as C_ntua suggested which is to simply maintain a single global variable which is a pointer to game.

Magos, I know about Singletons and actually...

Yeah I realized that... What I ended up doing was I created a class Game which has pointers to all the characters as members and I have one global variable of type Game in my driver which I use to...

Hi,

I'm working on a pacman clone in C++ and I'm using GLUT for the graphics. While I was coding the game, I was using global variables to pointers to objects pacman which is of type Pacman, and 4...

thanks I got so lost in playing with inheritance within the pacman class that I lost sight of the fact that it's totally normal to have mutators and accessors be public haha. thanks for bringing me...

Hi,

I have a base class character, a child class pacman, and a file called manager.cpp which contains main and serves to manage the characters in the game while the game is in progress.

In...

I've got a class Pacman declared as follows:


#ifndef PACMAN_H
#define PACMAN_H

#include "Character.h"
#include "Map.h"

class Pacman : public Character

DOH!

...right

thanks!

Right, but for the speeds, the compiler complains (I'm using VC++ 2005) if I move the constant speed definitions into the class declaration since they are not of integral types.

If I can't declare...

Thanks laserlight, you're always so helpful!
I did include a virtual destructor for base class character though didn't I?
I have:
virtual ~Character();

isn't that the virtual destructor??
...

Hi all,

I've got a base class Character and a class Pacman derived from Character.
Character is defined as follows:



#ifndef CHARACTER_H
#define CHARACTER_H

1. Are we required to provide default definitions for (non-pure) virtual functions in a base class? My intuition tells me yes because from what I understand a base class with virtual functions (and...

Hi,

I have a real beginner question for you all.


double * GetSalary()
{
double salary = 26.48;
double *HourlySalary = &salary;

Oh ok so I had the wrong idea. Thanks for clearing that up for me Kurt, that one sentence totally demystified it for me!

Right... thanks!

Oh ok I think I get it now...

So the const in the function declaration that follows the parameter list is not just a promise that the function itself won't modify the arguments but it is also a...

Ok well I'm trying to make sense of these two lines my professor wrote in an example program to simulate STL vectors:



T & operator[](size_type i) { return data[i]; }
const T &...

Okay so in this example, where I'm simulating STL vectors with
limit = a pointer to the memory location AFTER the last available one
avail = a pointer to the next available memory location
...

Pass by constant reference ensures that the argument won’t be modified BY THE FUNCTION. So if in the function you push the argument onto a vector then return from the function, you then have the...

Hi,

To include const in a function declaration, does that actually ensure that the function does not modify the arguments passed to the function? Or is it just a sort of promise to the user from...

Hi,

Can someone please explain to me exactly what happens when line
Rational result = left;
is executed?


Rational operator+ (const Rational & left, const Rational & right)
{
Rational...

Okay, well if it's not possible, can anyone think of a way that I might be able to print a line e.g.
3.8045e+00 5.3859e+34 5.3853e+53

i.e. maybe is there a way where I can print columns of...

Hi,

I'm trying to print a number but it's printing like this:
1.0000e+000
but I want to only show two 0's after the e+, do you know of any manipulators or something I could use to restrict the...

What a great way to start the semester... That was seriously my first example.

Anyway, thanks for the help guys! I just wanted to make sure I was tracing it correctly and that it was actually an...
