A MessagePack serializer implemented in pure GDScript

• No dependency
• No native binding required

Copy the msgpack.gd at the root of the repository into your godot project

var Msgpack = preload("res://msgpack.gd")

func _myfunc():
    var data = {"type": "wizard", "attack": 10, "weapon": ["dagger", "staff"]}

    var res = Msgpack.encode(data)
    print(res.result) # A PoolByteArray of the data encoded MessagePack

    var res2 = Msgpack.decode(res.result)
    print(res2.result) # Get back the original data

Convert a value (number, string, array and dictionary) into their counterparts in messagepack. Returns dictionary with three fields: result which is the packed data (a PoolByteArray); error which is the error code; and error_string which is a human readable error message

Convert a packed data (a PoolByteArray) back into a value, the reverse of the encode function. The return value is similar to the one in the encode method

• Only support null, boolean, integer, float, PoolByteArray, string, array and dictionary. No support for other data type like Vector2 and Vector3
• No support for the ext datatype in MessagePack
• Slow compare to the built-in binary serialization in godot
