too early (Page 2 of 4)

here's what *should* happen.
i believe you are knowlegeable of the past stable battle model, which basically states that a regiment flees once 50% of it dies, that's a static number, that doesn't change, and has no *luck* in it.
on speed, it's somewhat different.
the regiment fights as normal, till 10% of it is dead.
the moment 10% are dead, the regiment *thinks* whether it should flee or not. battle circumstances have no effect here on deciding, it's a random 50% chance of either staying or leaving.
if it decided to stay, so be it, it fights.
on next round, it asks same question, with same 50% chance.
and so on.
before the 10% loss, it should NOT question this at all.
spells that effect fleeing, usually affect the 50% chance, make it 60% or more in favour of fleeing, but the 10% does NOT, and should NOT get touched. (at least, following the model Vilmore has designed)
as you can see, a regiment fighting 2 rounds after losing 10% has a 25% chance, fighting 3 rounds is 12.5%, and it keeps decreasing, have 3 regiments in a battle fighting 8~9 rounds after losing their 10% is just.... weird, specially when it happens in the most gruesome of battle, and *twice*, with a battle in between them in which they fled way too early when i wished they would have stayed...
i am NOT from belgium, i swear!!!!

I still think you might have some belgium blood!

Anyways, you are not correct in the things you say.
After 3 rounds you don't have a 12.5% chance they stay... you have 3 times 50% chance.
There is a big difference, and it's even bigger for belgiums!

As requested, the formula for morale checking:

/*
    Returns TRUE if this troop keeps fighting
    @param $unit: A unit (regiment) object.
    @param $morale: Morale of the unit (default 100)
    @param $orgAmount: Original amount of units before the fight started
    @param $curAmount: Current amount of living units
    @param $killedLastRound: Amount of units killed in current (last) round.
    TODO: Make a better morale check.
*/
private function checkMorale ($unit, $morale, $orgAmount, $curAmount, $killedLastRound)
{
    $percentage = $curAmount / $orgAmount;
    
    $chk = true;
    
    if ($percentage < 0.9 && $killedLastRound > 0)
    {
        $chanse = 100;
            
        foreach ($unit->getEffects () as $v)
        {
            $chanse = $v->procMoraleCheck ($chanse, $this);
        }
    
        $chk = mt_rand (0, 200) < $chanse;
    }    
    
    return $chk;
}

This function is called after every "round", that means, after all attackers and defenders have attacked.

And, yes, I don't like random factors in the game, but this is something Vilmore came up with

I'm guessing something goes wrong in one of the effects (spells). I'm going to add a large amount of debug data to sort this out and also to give extra details about the troops during battles.

I don't think that's correct... If I'm understanding how the code works, it's a conditional probability, correct?  Bayes' Law with P(A|B,C) ... I am so not willing to solve that tonight

For those who do not know, its from a movie. 

Next post here will be constructive, I swear. 

demonic needs a math class

Am I to assume that

$chanse = $v->procMoraleCheck ($chanse, $this);

is where the spells and whatnot get applied?

Also on what condition does a unit flee?  true/false?

If I had to take a guess at it I would say the function is not behaving as it should or mt_rand().... but I am not 100% what that is.  ( I assume random number between 0 and 200).

edit.

Looking back through it a 6% loss should not even call either of those functions.  treachery is afoot.

well, you said there was a 50% chance of winning the lottery, so that explains why i mentioned how small that chance is...
and about the difference belgian-dutch: belgians are from belgium, dutch are from the netherlands, that is all i was saying you make me feel smart around here xD
and i know there is a difference between statistics and math calculations, but english is the 3rd language i learned, so sorry if i make any mistakes speaking or writing it

you can't express female beauty in exact figures and numbers, it's the roundings that make it so beautiful

strange. I'm from Belgium and I speak Dutch.
Now I'm confused.

i found the answer to original problem, Daed has been made aware.
troops aren't fleeing early... they are so embarrased they have been reporting their numbers wrong to avoid post-battle court martial....
basically, if i send a 100 troop regiment, i would expect it to start considering fleeing once it loses 10 troops at least....
suppose the regiment is losing 6 troops per turn, the log would look like:

some jerk (xxx troops) kill 6 troops from whamra's heroes (100 troops)
etc...
some jerk (xxx troops) kill 6 troops from whamra's heroes (94 troops)
whamra's heroes (94 troops) run away.

that 94 is deceiving... after a long bloody battle, one find difficulty doing a count on correct numbers, but they are in fact 88 when leaving in this scenario, not 94..

Well, thank you very much for the explanation.
Your wise words really make me feel so dumb.
but i'm learning really fast, could you post some more of your wisdom?

So it's wrong to call a Dutch speaking person Dutchie?
(sorry but I'm blond)
