Files reference

File I/O, filesystem queries, directory listing, compression, hashing, base64, random. Files.* namespace binds raylib's rcore.c file API; Random.* binds SetRandom*.

Raw data I/O

Files.load_data(path: String) -> [UInt8]

Category: I/O · raylib: LoadFileData

Load file contents as a byte array.

val bytes = Files.load_data("assets/data.bin")

Files.save_data(path: String, data: [UInt8]) -> Bool / export_data_as_code(data, path) -> Bool

Category: I/O · raylib: SaveFileData / ExportDataAsCode

Write bytes to file; embed as C source.

Files.save_data("save.bin", bytes)

Files.compute_crc32(data: [UInt8]) -> UInt32

Category: Hashing · raylib: ComputeCRC32

CRC32 checksum (ISO 3309 polynomial). Canonical vector: "123456789" → 0xcbf43926.

val crc = Files.compute_crc32(bytes)

Files.compute_md5(data: [UInt8]) -> [UInt8]

Category: Hashing · raylib: ComputeMD5

16-byte MD5 digest (RFC 1321). Canonical vector: "abc" → 900150983cd24fb0d6963f7d28e17f72.

val digest = Files.compute_md5(bytes)

Files.compute_sha1(data: [UInt8]) -> [UInt8]

Category: Hashing · raylib: ComputeSHA1

20-byte SHA-1 digest (FIPS 180-1). Canonical vector: "abc" → a9993e364706816aba3e25717850c26c9cd0d89d.

val digest = Files.compute_sha1(bytes)

Random

Random.get_value(min, max: Int32) -> Int32

Category: Random · raylib: GetRandomValue

Inclusive random integer in [min, max].

val d6 = Random.get_value(Int32(1), Int32(6))

raylib cheatsheet · Iron source · Test usage

Random.load_sequence(count: UInt32, min: Int32, max: Int32) -> [Int32] / unload_sequence(seq)

Category: Random · raylib: LoadRandomSequence / UnloadRandomSequence

Generate a non-repeating shuffled sequence (Fisher-Yates). unload_sequence does nothing in Iron because the sequence is garbage-collected.

val deal = Random.load_sequence(UInt32(52), Int32(0), Int32(51))
