Cutie Bomb Server
My excuse to learn Erlang -- an attempt at writing a TCP/IP socket server for the old flash game Dinky Bomb. I have chosen to call this Cutie Bomb Server because I don't fancy infringing any trade marks.
What I have discovered
- Dinky Bomb communicates using Flash's XMLSocket class
- Messages are sent as XML elements (see:
docs/elements.xml) and terminated by a null byte ($\0). - The cuties on each team are enumerated such that it is odds vs evens (DefineSprite 1022 > frame 1 > DoAction:19)
Roadmap
- get the game to run on localhost
- mock XML for user interactions
- figure out inter-process communication & global state. ets?
-
replace mock data with real data - implement all events/states
- implement any timeouts and resource clean-up required
- test
- legal due dil/permission seeking
- deploy somewhere, for great justice

Useful tools
Build
./rebar3 compile
./rebar3 releaseStart a web server
A web server is needed to avoid browser resource security problems. Python3 has a built-in web server:
cd cutiebomb-server
python -m http.serverStart the game server
cd cutiebomb-server
./_build/default/rel/cbombserver/bin/cbombserver consoleState Transition Table
