    Maybe you should post some of your code so we can help you find the bug in your program.

    well, uh.. i kinda deleted that part. But heres an example of what it looks like, trimmed of course.
    Code:
    int pexp = 0; //Player Exp.
    int plevel; //player level
    lu1 = 10; //level up 1
    lu2 = 30;
    lu3 = 50;
    
    int main()
    {
    if (pexp >= lu1)
    {
    plevel++;
    }
    }

    You should check backwards for the level. I mean, check first for level 5, then level 4, level 3...
    With the code you have, it'll add 1 to your level count even if the player is already in or above that level. You could also check for the level s/he's in. It'll be useful to work with absolute values rather than relative. What I mean is: if the player has enough exp points to go to level 1, make the level 1, instead of adding one, which could also solve the problem.
    Just a few suggestions.

    I had code like
    Code:
    if (pexp => lu5)
    {
    cout << "Level 5!\n";
    plevel = 5;
    }
    and worked my way down the chain from that.
    It still did the same stuff.

    I'd suggest you make an algorithm for the experience needed, or at least make a table for them instead of lots of hardcoded if-statements.

    Assume you gain a level for 6 exp, the the amount required doubles for each level (6, 12, 24, 48, 96 etc...):
    Code:
    int CurrentExp = 0;
    int ExpForNextLevel = 6;
    int CurrentLevel = 1;
    
    void CheckForLevelUp()
    {
       //Loop several times in case you gain enough experience for multiple levels
       while(CurrentExp >= ExpForNextLevel)
       {
          //Increase stats like Strength and Health here
          ...
    
          //Increase the level
          CurrentLevel++;
    
          //Set the exp for the next level, in this case double it
          ExpForNextLevel *= 2;
       }
    }

    I use rand() for the damage. How could i use that with the levels?

    Have a base damage and a variable damage counter, which you increase on levelup. Then calculate the damage from:
    Code:
    BaseDamage + (rand() % VariableDamage)
    The damage will then range from BaseDamage to BaseDamage + VariableDamage - 1, thus be increased by each level.

    ok blizzard, if you want a "decent" level up system, you should have something like this:

    Code:
    #define NUMLEVELS  99    // This is the max amount of levels the character can get
    
    int levelExp[NUMLEVELS]; //Create a huge table of all the exp
    int pExp;  //player's exp
    int pLevel;  //player's level
    
    void testLevelUp();
    void initAll();
    
    int main()
    {
          initAll();   //Initialize all of the variables
    
          //  ^^ that code should be placed at the very top, outside of the game loop, because it sets up the default settings for each variable
    
         //  Here would go any other setting up
    
         while(1)   // Just making an infinite loop because I don't feel like making an entire engine, lol
         {
              // Now, what you want to do here is, before you go trying to test the users exp EVERY loop, only test it at the end of a battle or whatever you're using for your game
              testLevelUp();  //Test if you leveled up
         }
    }
    
    void initAll()
    {
         int b=10;
         for(int a=0;a<NUMLEVELS;a++)
         {
             levelExp[a] = b;
             b+=6;
         }
    //explanation of above ^^ code:
    //
    // This code will run through all of the levels, in this case 99
    // and set up their default values
    // then, you store b to the levelExp slot for the current level being
    // edited, and that'll make your list of level exp's you need
    // also, you need to increment the b value, otherwise it'll just keep
    // making all of the values equal 10
    // you may want to add something like:
    // b+=rand()%10+5;
    // instead of   b+=6, and if you don't want it to be different every
    // time, DON'T seed it, or seed it with the same thing every time
    // that way it will be a little more interesting
    //
    
         pExp=0;
         pLevel=0;
    }
    
    void testLevelUp()
    {
       if(pExp>levelExp[pLevel])  //test if the player's current exp is greater than the current level's required exp
          pLevel++;
    }
    wow, lol, I just made all of that up off the top of my head in 10 minutes, lol, I should start making dos games again, i forgot how simple they were

    well, I hope that that helps you, and anyone else who has this problem

    oh, and if i didn't say earlier, the problem with your code was that you were testing if your exp was greater than level 1's requiered exp value, then add the level, therefor, say....

    if you have 53 experience
    and you need 20 for level 1, 36 for level 2, 57 for level 3
    and you do your version of the testing, you'll level up to level 2

    see what I mean? if not, just reply here again or pm me

    -edit-
    oh, i just noticed magos' post, he kinda mentioned the same thing, but with this one, you can actually have a lookup table of everything, and if you want it to double in exp every time like his does, just make b*=2;

    Well, it might, its just that, when i have 1090 exp, it would level out of level 1, dontcha think?

    i don't seem to understand what you mean, if you mean, it'll only level out of each level once, and not go up to the next one with the exp, then you just do a loop, like so:

    Code:
    while(pLevel<NUMLEVELS)
    {
       if(pExp>levelExp[pLevel])
          pLevel++;
       else
          break;
    }
    and that will run through all of the possible levels you can go up, until you've reached a point where you can't level up anymore

    -edit-
