So, I converted exit_info to extended bitvectors. I've converted all the code, but one pice. I am stuck here.

proom->exflags[x] = eroom->exit_info;

I can't seem to convert that bit to accept extended bitvectors. This is within ships.c in do_makeprototypeship.

Now, I don't even think makeprototypeship works, but I'd like to move in that direction, so I figured this would be a starting point.

Any ideas?

Also, anyone else messed with extended bitvectors much? pros? cons?

Without seeing the code, I'm left to assume that proom->exflags[x] is meant to be part of an array of integer values. The extended bitvectors are actually a struct, so you can't assign that to an integer. You'd need to modify the code you're stuck on to give exflags[] the integers it wants, or modify it the other way to make exflags[] hold EXT_BV data instead.

Since Smaug 1.4 and onward come with extended bitvectors by default, pretty much everyone has dealt with them in some way who uses that. Using EXT_BV allows you to go up to 128 bits instead of being stuck with 32. So you have more room to add things you might need. I can't really think of any cons to the system right now, other than the amount of work it takes to convert a set of flags to use it.
