static 
Increases the drop amount according to a binomial distribution. The function will roll maxBase+level times, and add 1 if a random number between 01 is less than the given probability. Each level of fortune adds one extra roll.
As many as maxBase+level items can be dropped. This applies even if the fortune level is 0.
 Parameters

float  $chance  The chance of adding 1 to the amount for each roll, must be in the range 01 
int  $min  Minimum amount 
int  $minRolls  Number of rolls if fortune level is 0, added to fortune level to calculate total rolls 
 Returns
 int the number of items to drop

) 
 

static 
Calculates a chance of getting an extra bonus drop by reducing the chance divisor by a given amount per fortune level.
 Parameters

int  $divisorBase  The number to divide 1 by to get the chance, as if the fortune level was 0 
int  $divisorSubtractPerLevel  The amount to subtract from the divisor for each level of fortune 
 Returns
 bool whether the bonus drop should be added

static 
Calculates a chance of getting an extra bonus drop by increasing the chance by a fixed amount per fortune level.
 Parameters

float  $chanceBase  The base chance of getting a bonus drop, as if the fortune level was 0 
float  $addedChancePerLevel  The amount to add to the chance for each level of fortune

$maxBase 

) 
 

static 
Adds the fortune level to the base max and picks a random number between the minimim and adjusted maximum. Each amount in the range has an equal chance of being picked.
 Parameters

int  $maxBase  Maximum base amount, as if the fortune level was 0 
 Returns
 int the number of items to drop

◆ weighted()
static pocketmine\block\utils\FortuneDropHelper::weighted 
( 
Item 
$usedItem, 


int 
$min, 


int 
$maxBase 

) 
 

static 
If a random number between 01 is greater than 2/(level+2), this multiplies the max drop amount by level+1, and picks a random amount between the minimum and multiplied maximum. Each level of fortune increases the chance of fortune activation, and also increases the maximum drop limit when activated.
Otherwise, returns a random amount of the item between the minimum and original maximum.
 Parameters

Item  $usedItem  The item used to break the block 
int  $min  Minimum amount 
int  $maxBase  Maximum amount, as if fortune level was 0 
 Returns
 int the number of items to drop
