5D Diplomacy With Multiverse Time Travel

Based on Diplomacy and 5D Chess With Multiverse Time Travel, 5D Diplomacy With Multiverse Time Travel is an (entirely un-serious) attempt to introduce multiverse and time travelling elements to the classic game of pure negotiation.

The current code takes the simplest non-trivial Diplomacy board and turns it into the starting point of time travel shenanigans.

Disclaimer

The code is likely rather buggy, especially around retreats, and isn't resistant to badly formed inputs at all.

It's also horrendously ugly. I might fix that in the future, I might not. I consider this hackathon-esque in my approach, so please ignore my entirely undocumented, crazily formatted, paradigm-hopping mess. It works well enough for the demo, and that's all I need.

Requirements

• Java 14 or higher
• 500 IQ

How to Play

Compile the source code and run processing.GameRunner from the command line or similar.

You'll be prompted to enter orders. You must submit an order for every unit of either colour on an active board (shown as more opaque) and cannot submit orders for units on inactive boards.

Enter orders on separate lines and write r on a new line to finish submitting orders and resolve.

The format for orders is as follows:

• Hold: x1,x2,x3, where the x1 is the column of the board on which the unit lies (left-most column is 0), x2 is the row of the board on which the unit lies (may be negative as the centre is 0), and x3 is one of [0, 1, 2] to specify the unit's location within a board. Here, 0 refers to the left region of the triangle, 1 to the top region and 2 to the right region.

• Move: x1,x2,x3 m y1,y2,y3 where x1,x2,x3 specifies the unit's location as above, and y1,y2,y3 similarly specifes the unit's destination. Units can move anywhere on their own board or anywhere on boards one space away horizontally, vertically or diagonally.

• Support: x1,x2,x3 s y1,y2,y3 z1,z2,z3 where x1,x2,x3 is the supporting unit's location, y1,y2,y3 is the supported unit's location and z1,z2,z3 is the supported unit's destination. If y1,y2,y3 and z1,z2,z3 match, the order is a support to hold in place. The supported destination is subject to the same constraints as a move order, i.e. a unit can only support to places it could move.

If retreats are required, you'll be asked to enter orders again for each dislodged unit only. Disband orders have the same format as holds, and a retreat move has the same format as a regular move.
