Inbetween replying to trolls on the Latest Drama Thread :rolleyes: I have somehow managed to get GroovyMud 0.3-alpha out.
0.3 contains many enhancements, including:
area support - areas can be scripted using plain ol' groovy or using the Grails beanbuilder
Complex behaviours can be built and added to any mud object, including SpawnBehaviours, TriggeredBehaviours, RandomBehaviours and ScriptedBehaviours.
MOBs can be scripted using a DSLs (domain specific language) stylee, eg mob.say("hey"); mob.get("broadsword"); mob.go("south")
Objects can use templated views, much like JSP, to build object descriptions. (This is still a little bit in flux, and subject to minor changes)
MOB logging - logs what mobs can see. configurable (as it's Log4J at the heart)
Player I/O filter object that can be added to the players shell, to enable things like drunkeness (removing characters, changing words in their output) and automatic text translation (still in a bit of an untested state)
Note that although this is under the Java section of the repo, the language you would use to build any mud would be the Groovy programming language, which is a separate language in it's own right but runs on the JVM.
(Maybe we should call that section "JVM" rather than "Java"? I could equally write a JPython or JRuby mud on the JVM .. but I digress :)
