Talk:Standards:MMP

Currently the biggest item missing from the IRE samples (and the Mudlet interpreter) is handling of Special Exits.

I have added support for our door types (IRE MUDs do use a `door="1"` as an exit attribute and also a `hidden="1"`) so that door type "1" corresponds to our "open door" marking, "2" to "closed door" and "3" (and `hidden="1"`) to our "locked door".

Not documented here is that all of the official five (now four) IRE Mud XML files now include an "HTLMColor" attribute as well as a "Color" number attribute. Last time I checked four (now three) of them all had the same color number to HTMLcolor "names" (actually a 6 hex digit/24 bit "rrggbb" code that Qt can comprehend as a QColor::name if it is prefix with a '#' IIRC) but one use different shades of similar colours for a richer colour experience - e.g. swimmable water might be a different shade of blue to deep water as their HTMLColor attribute - but still had the same basic (16 colour) "Color" attribute for those different "environments". As for environments we do not currently capture the "Description" data and we map the colour "Color" codes to our "ColorID"s with a generated lookup table that is totally inaccessible and unmodifiable (but stored in the Mudlet binary map file format so it persists) by the end user!!!

There are some more features in the MMP files that are used by IRE right now. I have an XSD file ready that validates against the current files, but I'd like to add some more comments to it first before publishing it

This is the XSD file that I came up with, what do you think?:

A pictorial representation would be this:

Not sure if the "hidden" attribute is applicable to the "exit" that has it or the "room" that it goes to as you have put here. Also I have only seen door="1" for exits - though I coded as if "0", "2" or "3" were possible and mapped hidden="1" to be the same as door="3"... I wasn't aware of the ability to have only a portion of a map (one or more complete "areas") and Mudlet would not behave nicely with such a thing with the current XML importer (it throws away the existing map when it reads a new XML file). IIRC Exits to rooms that are not present in the particular XML file loaded will get converted to stubs - this will be recorded both in the errors.txt log file and in a specifically crafted Room User Data entry for the starting room for the exit route. slysven (talk)

You're right, the "hidden" flag should hide the exit instead of the room, my fault. I will also amend the comment the door comment to be more open and we should probably have an "implementation status/notice" page where we list which standards are implemented and where/how we derive from them. We could note the additional exit values there. The same with the single area maps: we should note this on an implementation status page.
