Slick Forums

pl.shockah:
BiHashMap - a HashMap with easily accessible both keys and values
BinBuffer - buffer class with a possibility of storing unsigned values and values using odd number of bytes (like 3, 5, 6...)
BinFile - makes it easy to write/read BinBuffer's data to/from a file
Config - easy config structure, using lines like "myOption = 1234" in files; also supporting subconfigs ("myCategory->myOption = asdf")
DoubleHashMap - a HashMap with pairs of values of the same type (add a pair 1,5; now looking for 1 will return 5 and looking for 5 will return 1)
FileLine - easy line-by-line reader/writer
Helper - useful functions
HTTPQuery - easy HTTP connection with reading and writing of data
NonNullHashMap - a HashMap that doesn't store null values (putting a null value will just ignore it, or remove a current non-null key-value pair)
Pair - a structure for holding a Pair of objects
PairNonOrdered - like above, but doesn't really care about the object order (which one is first and which one is second)
Reflection - reflection helping class
Security - functions for hashes, etc. (for now only BinBuffer -> MD5 string)
StringTools - URL string escaping, stripping disallowed Windows filename chars, imploding an array of strings, checking if a string can be parsed as a number
WeightedRandom - a random with set number of chances per each value (think of it like of a lottery, the more "chances" you buy, the bigger the chance you'll get choosen)

pl.shockah.audio:
Audio - abstract class for sounds and music
AudioWave - wave sounds (wave data, instead of sequences of sounds like MIDI files)

Stream - streamed wave sound (for music)

pl.shockah.nbt:
Tag - abstract class for NBT tags
TagCompound - a tag storing other tags (like a directory of files on HDD)
TagList - a list of tags of the same type
TagByte, TagShort, TagUShort, TagInt, TagUInt, TagFloat, TagDouble, TagString - simple tags storing a value

pl.shockah.tasks:
