Combat Simulator?

I'm working on creating a combat simulator.  This way a single PC can be pit against various foes and we can get some detailed statistics about what actually happens when the PC and various monsters fight head to head.

 

What I hope to accomplish with this simulation is to be able to gather data such as:

 

What percent of the time a specific fighter at level X build 1 turns an orc

What percent of the time a specific fighter at level X build 2 turns an orc

What percent of the time a specific fighter at level X build 3 turns an orc

 

The percent of wins the fighter achieves

 

The percent of the time the orc 1 turns the fighter

The percent of the time the orc 2 turns the fighter

The percent of the time the orc 3 turns the fighter

 

The amounts of hp the fighter has left on winning

The amounts of hp the orc has left on winning

 

The average number of turns the fight takes.

 

 

 

Ultimately this combat simulator can help answer questions about how much stronger and weaker various melee builds are compared to each other.

 

 

 

I will begin by including options for the abilities of the primary melee classes.  Fighter, Ranger, Paladin, Barbarian, Monk.  I will include a few different foes for them to face off against.  I will probably limit the comparison to using abilities granted from level 5 and below.  Eventually the other abilities can be added in and other class abilities can as well.

 

I picture having a checklist of various features that I can toggle on and off for my pc and a list to choose the monster I will be facing.  I also picture having a place to enter a characters base stats and hit dice.  I also picture a place to select what weapon and armor you are using and a toggle for whether you are using a shield or not.  

 

 

Any thoughts, considerations or concerns?

 

**Note: This project will a bit of time to complete.

the way the game is balanced, the way the game is should basicaly should be 50/50 for a medium fight. how ever, is this an all out all resourcesmfight or what

I'll be happy to see the results, I much prefer a good combination of survival and DPR together over just DPR.

Yunru, what are the chances that a level 1 fighter beats a gnoll in melee combat

 

Let the Fighter Have

1d8 +5 damage

+5 attack

18AC

12 Hp

Use 2nd wind once when he is below 70% hp

 

 

What are the chacnes of such a fighter beating a gnoll in a melee fight 1v1?

I discovered a bug in my program where it was not giving the Orc a turn if the fighter missed. 

 

This will be corrected later. But as of now the current results are all invalid.  (I have went through and deleted those results to no one would get confused)

I've added in easy to use bugbear, ogre, orc, and gnoll stats.  (Only melee weapons are included since the simulator doesn't included any movement yet)

Just so you all get an idea of the relative toughness of these creatures here are some simulation results:

 

Fighter 1

12 hp

18 ac

5 attack

1d8+5 damage

***Used 2nd wind at less than 80% of maxHP

 

 

Fighter vs bugbear

Fighters wins 33.65%

 

 

Fighter vs gnoll

FIghter wins 77.56%

 

 

Fighter vs orc

Fighter wins 68.64%

 

 

Fighter vs ogre

Fighter wins 4.93%

 

 

*Note all win percentages were calculated over 1 million simulations
