Practical, small-scale approach for a class MUD combat core that fits a tight schedule and limited C++ experience. This ties back to points made by (keep it text-based), (separate stats/skill), and the project-management note from about handling uncooperative teammates. Implement a compact, well-tested combat module first, then add weapons, skills and effects once the core is stable.

#include <iostream>
#include <string>
#include <random>
#include <algorithm>

struct Character {
    std::string name; int hp, atk, def, acc, ev;
    Character(std::string n,int h,int a,int d,int ac,int e)
      : name(n), hp(h), atk(a), def(d), acc(ac), ev(e) {}
    bool alive() const { return hp > 0; }
};

static std::mt19937& rng() {
    static std::mt19937 g(std::random_device{}());
    return g;
}
int roll(int lo,int hi){ std::uniform_int_distribution<int>d(lo,hi); return d(rng()); }

void attack(Character& A, Character& D){
    int hit = roll(1,100) + A.acc - D.ev;
    if(hit < 30){ std::cout<<A.name<<" misses\n"; return; }
    int base = A.atk - D.def;
    int dmg = std::max(1, base + roll(-2,2));
    D.hp -= dmg;
    std::cout<<A.name<<" hits "<<D.name<<" for "<<dmg<<" (hp="<<D.hp<<")\n";
}

int main(){
    Character hero("Hero",50,12,3,10,5), gob("Goblin",20,6,1,5,2);
    while(hero.alive() && gob.alive()){ attack(hero,gob); if(!gob.alive()) break; attack(gob,hero); }
    return 0;
}

Core notes and next steps: the snippet shows a minimal resolution path—hit chance, simple mitigation, small variance, and enforced minimum damage. Balance by adjusting accuracy thresholds, variance range, and stat scales. Keep HP and damage as signed integers to avoid underflow. Seed the RNG once (as above) and isolate the combat functions from I/O so unit tests can drive battles deterministically (swap the RNG with a predictable seed during tests).

Extensions and project workflow: add weapon/armor modifiers, critical hits, damage types and a simple action queue for speed/initiative. For a group assignment, split tasks: one developer keeps the combat core small and tested, another handles the text parser/UI, and a third supplies data (monsters/weapons). If teammates fail to contribute, document attempts and present a working MVP to the instructor early, following ’s practical advice.

yes, you're in way over your head alright.
Leave programming games, and especially largescale games, to experienced people and start with beginners' tutorials.

You can NOT write the next Quake or Everquest on your own from the comfort of your bedroom, and especially not without years (think a decade) of professional experience.

Unless you're a genius of some sort then I concur with jwenting. There are some very good programming tutorials out there for C++. Check out this Blog for a link to C++ tutorials and a cool C++ IDE: http://www.daniweb.com/blogs/entry1325.html

Good luck on your programming odyssey, LamaBot

a good start is to make a simple text based rpg as it will teach you loops, switch statements, classes etc...

It he were a genius though he'd not be in "way over his head" as he claims :)
He'd also have a quite different way of expressing himself.

i know im in over my head but its a class assignment i have to make a mud text based game with combat and im in a group with two people who cant tell their heads form a hole in the ground

Read up on "rogue", the classic text mode game.

You have weapons, which cause variable amounts of damage
- knife, 1 to 5
- broad sword, 20 to 50

You have armour, which resists damage
- leather, 1 to 5
- plate, 50 to 100

You have skill, which affects your competence at using weapons and defence. If you have no skill, your knife attack scores 1 and your broad sword always misses. Likewise, you always get hit.
With lots of skill, your broad sword smites your enemies as you deftly dodge all attempts to harm you.

Take that up with your teacher. Approach him and tell him the others are not doing anything and effectively leaving you to do all the work for them.
(s)He should know how to deal with such situations, at the very least you'll have covered your as* :mrgreen:
