I am interested in developing/implementing a new container type specific_container, that will only allow a certain object to be put into it. Does anyone think this is possible?
My first idea would be to use this for sheaths and scabbards, that would only hold specific weapons. Then I could implement a Draw and Sheathe command for taking the weapon out and automatically wielding it, or unwielding the weapon and automatically putting it into the sheath container, which is worn.
How hard is it to implement a new container type?
Any help/thoughts on this are appreciated.

I think the easiest thing to do would be to simply use existing container, but utilize the unused value fields. For example, you could put a check in do_put:

if (obj->value[3] > 0 && obj->value[3] != putobj->type)
send_to_char("That container cannot hold that type of item!", ch);
return;

Then in build.c, you could simple use "oset <obj> v3 <itemvalue>", or write something that would accept a word rather than a number. This could be done by copying "oset <obj> type <word>", but make it affect v3 instead of obj->type, since its stored as a number anyways.

This avoids a large headache with new container, because there is lots of code dealing with them that might be above a beginners head. Plus this method does not require more fields or object type, just a little bit more code.

Thanks Greven, that is an excellent suggestion. Now I have a direction to go in. By the way, you may have noticed I am trying to work on smaller things, to help with learning, rather than my favorite idea of tactical movement. But someday, after I have learned more, I will revisit that idea, and thanks to folks like you, maybe I will actually make it work.
