A

Action 
An action is a command sent from the client to the server. For example "move to the right".
Arianne 
Arianne is the umbrella project currently developing Marauroa, Stendhal and Marboard.

D

DAO 
Data Access Object

E

Event 
Events are sent from the server to the clients to denote a stateless one time event. They are handled by the class RPEvents and always belong to an RPObject. The normal visibility rules apply. Unlike changed attributes events are fire and forget. For example, they are useful for chat messages.

FAQ 

G

GenerateINI 
see server.ini

M

Marboard 
Marboard is an early prototype of an easy to use vector graphics program allowing live collaboration over the Internet. While it is not ready for production use yet, it is a good proof that Marauroa is suitable for serious applications, too.
Message 
The low level network communication between client and server is message based. There are for example messages for login attempts and confirmation or rejection of the login. Actions from the client to the server and perceptions from the server to the client are transmitted using messages, too. As a developer using Marauroa to code your own game, you will not see those messages as they are only used internally. The page on network design explains the inner workings.

O

Object 
todo

P

Perception 
Perceptions are information about the zone and its content sent from the server to the clients. Marauroa uses a delta^2 algorithm to keep the size of the network traffic down.
Protocol version 
The version of the protocol used for the client server communication. (Details)

S

server.ini 
server.ini is the configuration file of the Marauroa server. It contains both game specific configuration information for the engine and administration related information for example how to reach the database. Most games (and even marauroa itself) provide a GenerateINI program to generate a stub.
Stendhal 
Stendhal is the most active game developed using Marauroa. It is a fully fledged and completely free multiplayer online adventures game (MMORPG) featuring a new, rich and expanding world.
Slot 
RPObjects and RPEvents can have slots that in turn contain RPObjects. For example in Stendhal players have a bag-slot that contains items.
SQL 
Low Level Database Access

W

World 
The world contains a number of zones.

Z

Zone 
A zone is an area that contains objects and players. Clients are informed about changes that occur in the zone they are in. Note: A zone can be a real area like Semos Village, Semos City or a virtual one like a chat room.
