Probability Function

I forgot to put in the (-25) roll penalty for the StealChance, however you have a general idea of what I've accomplished.

Isn't that just what you've tried to do with that code you posted?

if( StealChance >= BallHandlingChance)
{
Console.WriteLine.("Great steal by " +defenderName);

} else{

Console.Write.(+ defenderName " gets called for the reaching foul");

}

What do you guys think?

Now you've got it all randomized.
The random class has a much more convenient method with the signature

public virtual int Next(
int maxValue
);

and another one

public virtual int Next(
int minValue, int maxValue
);

-- so you don't need to do what you've done with %.

The convention is to write the names of the variables with a lowercase starting letter. I assume that RandomClass is an instance of the Random class? If so, it is an object, so the name you gave it is a bit misleading.
Anyway, you don't need to, or should use two random objects in this case - one will do just fine; the only thing you need to do is to call the Next(...) method twice.

The whole idea was to define an event such a "a steal has occurred", to define a way to calculate it's probability from the stats (in whatever way suits your needs), and to run a check against this probability, by generating a random integer number between 0 and 99 [including 99, which gives a total of 100 possibilities].
Or you could alternatively divide the probability you had expressed in percentage by 100, and then call rnd.NextDouble(), which would give you a greater precision.

P.S. And, when I say "to define" - I don't mean in code, but conceptually.

I assume the Steal and Handling probabilities have been calculated for players playing against exactly the same opposition, otherwise the %ages are pointless. I have 100% ball handling, having only picked a ball up once and got past one 12 year old. Does that mean I can get past a pro who has 68% steal?

I think the OP just tries to create a simulation/game like app, not some player performance analyzer. The stats are predetermined, possibly in a more or less arbitrary way.

I would like to know if a function exist that calculates the probability of the defender taking the ball from the offensive player. Like if (based on the stats) the defender has a 31% chance of making the steal.

Hmm ... maybe:

chanceOfSteal = (1 - ballHandlingRating) * stealRating

0.0118 = (1 - 0.98) * 0.94

How would you then use the result?

That's up to you - what do you want to do with the 'chance of steal' ?

Perhaps credit the defender with +1 steal and change possession. Sounds like the perfect implementation of Finite State Machines.

I'm looking into another possible way to achieve what I want. I would like to compare the two teams' stats then have it generate realistic statistical output.

On the other forum i have posted you a new message. Hope it helps its more or less an complete way to simulate your game.

Saw it, it is great stuff. I think I will use this method to simulate the game engine.
