1 1 Byte 16 Packet header - length of the packet
2 1 Byte 0x1C Packet header - packet type identifier
3 1 Byte 0x0F Packet header - sub packet type identifier
4 1 Boolean true IsMapChange; If false, it shows the teleport animation (white bubbles), and the client doesn’t remove all of the objects in its scope.
5 2 ShortBigEndian   MapNumber
7 1 Byte   PositionX
8 1 Byte   PositionY
9 1 Byte   Rotation
15 1 Byte   MapDiscriminator; The discriminator of the map, which tells maps with the same number apart, e.g. the stage of Devil Square (1 to 7). It’s appended after the 15 bytes of MapChanged, so a client can tell by the packet length whether it was sent.
