[Win32 Console] broken integer?
Apr 7, 2011 at 8:38am UTC
Hi guys, I have little problem with my program, I've started to learn c++ and now I wanna make custom "game" in console, unfortunatelly, I'm having problem, after calling player.load(); from player.cpp it should make Level = 10 and XP = 10 000 (data.txt), but after calling Level and XP in main.cpp they are same numbers (10, like Level)

You're not accessing the variables inside the class.
Create a function in the class, something like:
int getLevel();
Then:
1 2
int player::getLevel()
{ return level; }
And then, when you want to print it:
cout << player.getLevel();
You should also do:
1 2 3 4 5 6
int main()
{
//code...
return 0;
}

I had commands like this before, but I need to make Level and Xp different numbers and not to print them cuz I need to use them later in game (monsters will have HP like: player's HP*1,2 etc..)

But, by doing this, in player.cpp:
1 2
stringstream ss(qNewLevel);
ss >> Level;
You're saving the values to the protected variables, within the class.
And then, when you 'cout', in main():
cout << "Current Level: " << Level << endl << "Current XP: " << Xp << endl;
You're using cout to print the local variables created within main, and not the class. And you're more than likely getting warnings like the following, for using them.
warning C4700: uninitialized local variable 'level' used
To access the private variables within the class, you'll need member functions, like in my previous post.

and if I'll make Level and Xp public and not protected?

Just keep them protected and write member functions to access them.
And then, when you want to create monsters, do something like the following:
monsterHP = player.getHP() * 1.2;
If the players HP is 100, then all this is doing, is:

but after calling player.getHP() it will print player's HP on screen, or?
nvm, got it :) thanks!
