RPG Battle Algorithms

Expand Post »
I would really like for this thread to discuss all aspects of "RPG math" i.e.(Attack, Magic, Defense, Magic Defense, Agility, etc...)

So lets start off with Attacking. I am going to dismiss what the targets defense stats are and just think about raw attack power. So what are the elements of an attack? The elements I can think of would be strength, weapon, accuracy and skill. I believe the better your skill is with a particular weapon the more accurate you can be. So that is where it gets tricky for me. I've been able to come up with this:

(STRENGTH + WEAPON) * ACCURACY = ATTACK_POWER

To shorten things

(s + w) * a = x

But when you throw in skill to the mix I can't figure out where to add it in the algorithm.

I would split those up. Instead of lumping accuracy and skill into an attack, accuracy and skill would apply to a chance-to-hit calculation that gives you a percentage. If your random roll falls within that percentage, then you can move on to damage calculations using strength and weapon. That results in less work on a miss or block, and also saves you from overcomplicated single formulas.

Re: RPG Battle Algorithms

That does make since for accuracy calculations to be executed first before damage is even considered.

Since you're working with on a veido game, I would put it something like this.

if (ATTACK_TYPE != ATTACK)
{
     if (ATTACK_TYPE == MAGIC)
     {
          M + SBP = ATTACK_POWER;
          ATTACK_POWER - MAGIC_DEFENSE = DAMAGE;
          echo (DAMAGE);
          return();
     }
     else if (ATTACK_TYPE == SKILL)
     {
          S + SKBP = ATTACK_POWER;
          ATTACK_POWER - DEFENSE = DAMAGE;
          echo(DAMAGE);
          return();
     }
     else if (ATTACK_TYPE == ITEM)
     {
          IDMG - RESISTANCE = DAMAGE;
          echo(DAMAGE);
          return();
     }
}
else
{
     if (ACCURACY > TARGET_EVADE)
     {
          S + WBP = ATTACK_POWER;
          ATTACK_POWER - DEFENSE = DAMAGE;
          echo(DAMAGE);
          return();
     }
     else
     {
          echo('Miss');
          return();
     }
}

##NOTES##
M = Magic stat
SBP = Spell base power
S = Strength stat
SKBP = Skill base power
IDMG = Item damage
##END NOTES##


Of course, you'll have to figure out everything else out on your own. I was just hoping to help you get a basic idea.

Good luck, man (^_^)

I'm sorry man, but using other people's work in something that you're creating isn't cool. Granted, if you use something like phpBB in a CMS as a module, that's open source software and you can do that. I personally wouldn't use someone else's algorithms in something that I'm working on.

I think that you can create something entirely original and have it be awesome in your own way. Remember that the game that you're creating is yours to do what you want with. That's why you should come up with it all on your own.

If you want any help with it, then that's fine. But I don't think that asking to use someone else's work is a very good decision.

That's just my opinion, but I think that every video game programmer has it in them to create everything on their own (even the graphics if you have that knowledge).

I hope for the best in what you're working on. If you need any help, just ask and I or any of the other members will do what we can to help you out.

Good luck on what you're making (^_^)

I'm a freelance web designer that's majoring in game and simulation programming at DeVry University. I'll be starting college on March 3rd.

I had previously went to college at Utica School of Commerce (located in NY state) where I majored in computer programming and networking. I dropped out of USC because I was working at Turning Stone Casino & Resort as a cage cashier, seven days a week, up to 16 hours a day. I got injured at work, and while I was on worker's compensation, Turning Stone replaced me and is not willing to give me back my job. I didn't have the time to go to class... so I dropped out in my third semester.

Good programmers write good code; great programmers steal great code.

Everyone's entitled to their own opinion, I don't think that stealing code makes you a great programmer. Being great takes effort, and stealing code doesn't show effort. It shows that you're lazy.

That's my opinion, and just as you're entitled to yours, I'm entitled to mine. That is all that I have to say on that subject.
