Mud Resource IDs
They are encoded in a similar way to how ABI is encoded, albeit using slightly different methods.
Typically it’s possible to simply chop the 0x from the beginning, parse it as a BigInteger or another type that supports huge numbers, convert to a byte array and then to a string, trimming any \0 characters from the end.
However you can take the byte offset and length to extract out the parts of the string if you know what the scheme is:
var inputNumeric = BigInteger.Parse(inputRaw, NumberStyles.HexNumber);
var inputBytes = inputNumeric.ToByteArray().Reverse().ToArray();
var resourceType = Encoding.UTF8.GetString(inputBytes[..2]).TrimEnd('\0');
var namespaceId = Encoding.UTF8.GetString(inputBytes[2..16]).TrimEnd('\0');
var systemId = Encoding.UTF8.GetString(inputBytes[16..]).TrimEnd('\0');You can also do this from the command line as long as you have Foundry installed:
