Vaulderie

A webapp to make group Vaulderie less painful in LARPs

Requirements for development:

cd Vaulderie

npm install sinon # That's right, not npm install -g

Everyone puts in (max value you can put in is 20):

Alpha: 7 traits
Beta: 6
Charlie : 5
Delta: 5
Echo: 5

Here are the bond ratings before the Vaulderie (max bond rating is 10):

Alpha Starting rating  : NA/Alpha   2/beta   2/Charlie   1/delta   8/echo
Beta Starting rating   : 3/Alpha   NA/beta   1/Charlie   1/delta   9/echo
Charlie Starting rating: 5/Alpha   6/beta   NA/Charlie   2/delta   7/echo
Delta Starting rating  : 8/Alpha   7/beta    6/Charlie   NA/delta   9/echo
Echo Starting rating   : 6/Alpha   5/beta   5/Charlie   1/delta   NA/echo

All these values are added up

7+6+5+5+5=28 traits in all

Everyone takes out what they put in randomly

(7) Alpha takes 7. 1 of his own, 2 from beta, 3 from Charlie, 0 from Delta and 1 from echo
(6)Beta takes 6. 3 from alpha, 0 from beta, 0 from Charlie, 0 delta and 1 from echo
(5)Charlie takes 5. 0 from alpha, 0 from Beta, 1 from Charlie. 3 delta and 1 from echo
(5)Delta takes 5. 2 from alpha, 1 from beta, 1 from Charlie, 0 from delta and 1 from echo
(5)Echo takes 5. 1 from alpha, 3 from beta, 0 from Charlie, 2 from delta and 1 from echo

Now is the hard part, Each player must test against a each other to see if their ratings go up. If a rating is 10, it can only stay 10 or go down 1. Now let’s break down the results for Alpha:

pulled one of his own traits which does nothing
2 of beta’s traits vs his current rating of 2.
    1/3 chance for his rating to go up(loss)
    1/3 to stay the same (tie) rating =traits
    1/3 to have a chance to go down (win). If the chance to go down is pulled he has a 1/3 chance (win) of going down and a 2/3 chance to stay the same(tie or loss). 
3 Charlie traits vs his current rating 2.
    2/3 or the rating going up(loss or tie) rating <traits
    1/3 to have a chance to go down (win). If the chance to go down is pulled he has a 1/3 chance (win) of going down and a 2/3 chance to stay the same(tie or loss).
0 from delta, no change in rating
1 of echos vs his rating of 8.
    1/3 or the rating going up(loss)
    1/3 of it staying the same (tie) rating >traits
    1/3 to have a chance to go down (win). If the chance to go down is pulled he has a 1/3 chance (win) of going down and a 2/3 chance to stay the same (tie or loss).

This process is repeated for each member
