Build

$ rebar3 compile

Run

You must build before you run the following commands, and you must be running it on the Halligan server. Once the server is up, you can make rooms until it is down.

Server:
$ ssh vm-hw00
$ cd _build/default/lib/tetris/ebin
$ erl -name lebronjamie -setcookie monster
1> server:start_link().

Client:
$ ./tetris

We have one bug with Tuftris that we have never been able to figure out. Sometimes, certain homework VMs aren’t reliable (we’ve had the most trouble with 5, 7, and 9). When you launch the client (with ./tetris) and attempt to join a game (via single or multiplayer), sometimes an error will be thrown and the whole screen will get messed up. The reason is typically “nodedown” (it will be an atom in an Erlang tuple). When this happens, try sshing into a different VM until it works. We’ve typically seen this on VMs that are particularly busy (often it’s the VM you get when you first log in). We were never able to pin down this bug, as it comes up inconsistently.
