SUBJECT: WolfMUD v0.0.17 released
DATE: Sat 31 Oct 16:05:42 GMT 2020
The next release of WolfMUD, v0.0.17, is now available for download[1].
This is the seventeenth official release of WolfMUD. It’s not been that long
since v0.0.16 was released. Does this mean the release is just being made to
put something out for Halloween? No! It’s smaller than previous releases, but
there are some nice changes — which get us closer to implementing combat :)
First of all there is a fix for a data race that could happen if a player is
killed just before they hit enter on a command to do something. The chances of
this actually happening are tiny, but it was there and is now gone.
Three new attributes have been added: Holding, Wearing and Wielding. They
record what items a player is using when they exit the game so that the items
are still in use when the player logs on again. The attributes also allow zone
authors to have mobiles wear and use equipment. For examples see the city
guard, sweet flower girl and toy doll in the data/zones/zinara.wrj file.
To accompany the new attributes, and make them work, there are new LoadHooks,
SaveHooks and ResetHooks added to the code for Thing to provide hooks into the
post-unmarshal, pre-marshal and reset processes.
The final piece of the puzzle to make mobiles use their items is a new WAIT
value on the Reset attribute, which can be specified in zone files. Specifying
WAIT on a container will cause it to delay resetting until all of it content
is ready. Mobiles are treated just like containers for resets. Full details on
using WAIT, and limitations, are in the docs/zone-files.txt documentation.
For authors playing with resets and WAIT you can now specify the alias of a
disabled item on the #DUMP command. No more using #DUMP on a location just to
find the disabled item you want to inspect.
Of course no release would be complete without numerous other minor additions,
bug fixes and assorted tweaks…
Time to get out the pumpkin again!
