/* Plugin for exporting C++11 random number functionality
|
||||
*Exports functions for random number generation
|
||||
*Functions:
|
||||
- seedRNG(seed)
|
||||
- rollInt(min, max)
|
||||
- rollDouble(min, max)
|
||||
- rollNormal(mean, std_deviation)
|
||||
- rollBool(chance_for_true)
|
||||
- resetIndexRolls(string, array_length) --String identifies the instance of SimpleNumDistribution to reset
|
||||
- rollIndex(string, array_length) --String identifies the instance of SimpleNumDistribution to use
|
||||
--(Shuffles a vector of indices, Next() increments through then reshuffles when end() is reached)
