Move Minimap Click

Move minimap click is the packet that the client sends upon clicking on the player’s minimap while the minimap isn’t blocked off, to walk to the destination clicked on.

Payload

Even though the packet itself is defined as a variable-byte size, the payload’s actual size is always a constant value of 18, with certain static values being written in all the revisions. Only the x and z coordinate fields may have a different order from revision to revision(swapped between one another), the rest of the fields written in this packet are all always written in the same exact order. Everything besides the x, y and ctrl-click variables also always use the same exact byte modifications(or the lack of).
