I can make protos and any necessary scripts for new scenery and set everything up in the mapper so its ready to use. But I'd want to make it part of this expansion pack. That means its a whole new set of protos for everything (critters, items, scenery, etc) which will not be compatible with old maps. But the payoff for this incompatibility will be large since everything will be easy to find in the mapper.
The item arrangement is looking good, protos are arranged in
this order, click "next" to see the ordering (that's the order they appear now in my mapper selector bar). I am redoing the critters now so that there will be 3 protos for each of the 140 unique FRM sets (which already includes the FoT and FO1 critters). They will be weak, strong, and tough versions of each character or critter. Lots of room for customization this way, and ordered nicely. Ordering the scenery will be a big job because there are 1900 images and there are 1700 wall peices too. But I think the time spent in reordering this stuff will be worth it later.
One of the side benefits of ordering stuff contiguously is that I can make new script commands that operate on a set. For example I can make a new command createRandomWeapon(RIFLE) or createRandomTreasure. And with the weak/strong/tough arrangement of critters, it would be easy to script encounters that adjust based on the player's experience level. As you get stronger, so do your encounters ....
I like the idea of adding new contributed art, so if you send me some I'll make it work in the expansion pack. The expansion pack will probably not reach a version 1 for 1-2 months, just to keep expectations realistic. I wouldn't recommend that anyone use it for game development till I get to version 1.0, unless someone wants to help with testing.
