Multiplayer

Server

We created a custom tcp server that can be hosted locally or be put on a remote server

Local hosting

to host a local version of the server one just has to run the Server.java file as the main class with the port as the only program argument

Remote hosting

We hosted the game server on a remote ubuntu server (epflmp2.me) by first exporting the server as a jar file and by running this command on the remote server :

java -Djava.awt.headless=true -jar <serverJarName> &

this command runs the server as a background program. To not run it as a background program use the command without "&" at the end.

Requirements for remote hosting

as the remote server doesn't have a display we need to run the game with java.awt.headless set to true. This runs the java program in headless mode meaning we can't use JFrames.

Manageing a remote server

the command mentioned above runs the server as a background program which makes managing the program quite a hassle. To help with one can create a service (on Linux):

[Unit]
Description=gameServer Daemon

[Service]
ExecStart=/usr/bin/java -Djava.awt.headless=true -jar /root/Server 4000
User=root

[Install]
WantedBy=multi-user.target

this way all that one has to do is use these commands to run/stop the server:

systemctl start serversservice
systemctl stop serversservice

Client

The client connects to the tcp server by using the address, the port and username as program arguments

Connecting to our remote server

To connect to our remote server use the following program arguments:

epflmp2.me 4000 <your_chosen_username>

Connecting to your local server

To connect to your own local server use the following program arguments:

localhost <your_chosen_port> <your_chosen_username>

Multiplayer gameplay

shoot arrows at other players to damage them and destroy your enemies. For each enemy slain, you may upgrade your mighty bow by selecting an upgrade:

Press U for arrow range
Press O to deal more damage
Press I to improve reload speed
Press P for faster arrows
