PowerBoxer

This program solves the puzzle game Power Boxes from Fancade. The game consists of gravity-affected blocks that can either be a power source, a conducting block or a non-conducting block, and the goal is to slide them to the power outlets. If two sources conducts, either by being adjacent or being interconnected by conducting blocks, they both will go out and become conducting blocks. The solver always finds the solution with the least amount of moves. If the program reports that no solution is found, it means that is has tried all possible moves and couldn't find a solution.

Running

The program is written in Java and runs on Java 16 (or Java 15 with preview features enabled). Compile all sources using javac -d build src/*, enter the directory with cd build and run with java Parser.

Usage

Enter the puzzle, row by row, using these characters:

  • s for power source
  • c for conducting block
  • i for isolating block
  • o for power outlet (where the power needs to be, not the wall)
  • w for wall If an outlet is superpositioned with, lets say a conducting block, use uppercase C.

Example

Example
This puzzle can be entered as

     sicw
w  owwwww
wo   icsw
w   wwwww
wwwww

...and you end your input with "end". Note how the "o":s are placed on the block where the power needs to come from. Then, the program finds the solution and lists all the moves as previews and with coordinates, such as:

(5,2) -> (4,2)
        #
#   #####
#   ba  #
#   #####
#####

You should always move the piece at position "a" to position "b".
