After discovering some nifty things about SCOLs and a couple new scripting tricks, I'm almost ready to say that I can do this. In fact, I know I can, but I still need to learn a thing or two. First off, I need to learn how to make a message box. That probably seems simple to y'all who are used to doing it, but it's something that's stumped me for a while. My location is also chosen - and yes, while it is technically Springvale I like to think I chose a lesser-used spot. (I plan to call the final mod "Do It Yourself - Never Too Far From Home" as a reference as to how close to Vault 101 it is.) The spot in particular is a destroyed house, on the upper ridge, the smaller one. You'll know what I mean, when you get there and notice for yourself how flat the ground is there, even in the vanilla game.
Now, as for building the house, that's the easy part. My main realism/balance problem is where the player is going to get their materials. My plans revolve around a toolbox method, as in I'm going to use the toolboxes as the "Interactor" for the player to work with. Which really means that it pops up a message box, checks whether conditions are met or not, and the proceeds or doesn't with the next stage. But as I said, the materials bug me. I thought about just enabling piles of whatever it is I need (for example, when it comes time to build the walls, a pile of lumber can be scavenged from a nearby house or two, but the piles only appear when that stage is set) when I need them. But that just seems...cop out-ish. Unless y'all like that idea, of course.
But my input needs right now are how I'm going to introduce the materials I need. Oh, and - should I make time pass when the player assembles each stage? I would think yes, so that you don't build an entire house in a single day (for anyone that tried my OB mod, Odd Jobs, that kind of time passage).
