// Entering zone

/* Each zone should have some arrays with things that could be
dropped like those, where any object has a weight, meaning its 
probability, from example 0.05 of 1 will be the elemental sword drop percentage */

collectorItems={glacialStone,dinosaurBone,diessaChalice};
whiteItems={crap, crap, crap};
purpleItems={....};
dyes={....}

// Calculates the number of things that could be dropped 
Player.calculateDroppedItems(itemArray,zone.getNumberOfFoes(),zone.getTimesEntered());

// Calculation could be like:

/*

goldenItems = 200foes * GWUnknownFormuleOfDrop % 15timesEntered;
whiteItems = (200 foes - ObjectsThatAreGolden)* GWFormuleOfDrop % 15timesEntered ;
*/

// Gw stores the things that could be dropped, ie:

/*
goldenItems=3;
collectorItems=12;
.....
dyes=2;
totalItemsYouCanGet=goldenItems+.....+dyes;
*/

/*Then they activate a trigger when any creature dies
(just check if zone.getNumberOfFoes() goes down from the last check)
Lets think that you killed 5 foes
*/

for each foe in that 5{
/*
check itemsYouCanObtain, and if its 0, you get nothing

else just do a random number from 1 to N, 
being N the number of arrays i write above, 
for example 1, which will be golden items.

then, using the weighs, we calculate the drop from the list and... drop it

foes to end calculation -1;
goldenItems -1;
itemsYouCanObtain -1;
*/
}

/* the trigger will be activated anytime the game checks 
that number of foes has decreased
