# NAME
ttrts - Tiny Terminal RTS
# SYNOPSIS
ttrts MAPFILE
# DESCRIPTION
ttrts is a tiny terminal based RTS that uses text files as order lists to control the units
This means that any user, program or cat that can read and write to text files can play the game
# RETURN VALUE
ttrts will return -1 on error, or the winning player on completion
# OPTIONS
MAPFILE - File to read in the initial game state. Local or in ${TTRTS_MAPS}
# USAGE
When invoked, ttrts will set up the game in a directory within ${TTRTS_GAMES} by the name of the map
The files in this directory can be read and interpreted by human, robot or cat
ttrts will then await order files from each participant
Once all order files have been received ttrts will calculate the turn and output a new gamestate file
This process repeats until the game is over
# ENVIRONMENT
${TTRTS_MAPS} - Map file lookup location, defaults to `/usr/share/ttrts/maps/`
${TTRTS_GAMES} - Game directory for I/O, defaults to `/tmp/`
-----------------------------------------------------------
# FILES
`/usr/share/ttrts/maps/` holds a sample set of maps
## Gamestate File
Turn_{TURNNUMBER}.txt
### Contents
===== ttrts v{MAJOR}.{MINOR}.{PATCH} =====
NAME:{GAMENAME}
SIZE:[{X},{Y}]
TURN:{TURNNUMBER}
WALL:[{X},{Y}][{X},{Y}][{X},{Y}]...{repeat for all walls}
~~~~
UNIT:{ID} pl:{PLAYER} vs:{VIS} dr:{DIR(NESW)} ps:[{X},{Y}]
... {continue for all units}
END
## Order File
Player_{PLAYER_ID}_Turn_{TURN_NUMBER}.txt
### Contents
ORDER:{ORDER_CHAR} id:{UNIT_ID}
... {continue for all orders}
END
-----------------------------------------------------------
# GAMEPLAY
The game takes place in a series of simultaneous turns on an arbitrarily sized 2D board
Each turn, the client outputs a gamestate file and waits for an order file from each player
All commands are evaluated simultaneously with friendly fire enabled by default
The game is over when any of three conditions are met -
* All remaining units are controlled by a single player
* No units are left (draw)
* All units left are unable to move (draw)
# UNITS
Each unit occupies a single tile on the board, facing in a compass direction (NESW)
Units will only accept orders from their owner
Units can receive only a single order each turn
Units cannot occupy the same tile as other units/walls
# ORDERS
### F - Move unit [F]orward one space, leaving a wall
This wall will remain until the end of the game, blocking movement to that tile
Movement orders have no effect if impossible, eg.
* Attempting to move outside of map
* Attempting to move on to tile occupied by unit/wall
### L/R - Rotate unit [L]eft or [R]ight
Unit will rotate clockwise or counter-clockwise, this order cannot fail
### A - [A]ttack in straight line in front of unit
Attack will continue forward until unit can't progress, all units within the path of the attack are destroyed.
