X@COM

Work continues on the new mod, which is now mostly content-complete and soon to enter the playtesting/tweaking phase for a release sometime within the next week or so.

My own personal time sink (read: son) has been performing his role quite effectively, so I've been spending more time away from the computer in recent weeks. Seeing as how I'm still always home, and X@COM rarely leaves the screen so that I can type up new additions whenever I have a spare moment, while working on this mod I've had many a chance to gaze (longingly :)) at that this screen.

I love working with pretty data, lots and lots of pleasingly-colored data that lines up nicely and makes my eyes happy without killing them after staring at it for hours.* Maybe it's just nerd aesthetics getting the better of me, but seeing the data even from a distance is fun, so I've recreated the effect by taking screenshots during development and shrinking them down here. No need to read the content (which is too blurry, anyway), just enjoy the images. Of course you can always read the content when the mod is released, but that's not the point here (you also may not have as large a screen(s) as I do = less beautiful).

By percentage, coding has taken up far less of my time lately since this scenario (introduced in the previous post) is a mod, and therefore implemented entirely through text scripts.** So what you see here isn't source code, it's the scripts as they appear when viewed with X@COM-specific syntax highlighting.*** (My source is very organized and has some interesting shapes and color combinations to it as well, so I should put up shots of that some time.)

Here I'm designing props to be placed into the world. Their properties are listed on the top and some map pieces used in random generation can be seen at the bottom.

Entities (units) and their stats are listed at the top here while I work on defining the effects of their special abilities on the bottom.

Here I'm putting together the map pieces in earnest, placing objects and determining their behavior through the spawning scripts seen at the top.

Many new armor types here (since you can now swap out armor), some that enable special abilities.

All these new units (top), items, and abilities need cool new particle effects (bottom) to go with them. I've pretty much doubled the existing library of particle effects with this mod.

So barring the end of the world (I think we're past that now, right?), you should be able to play this soon.

*Less of a problem now, I must admit, since 15+ hour coding sessions died last year, sacrificed at the altar of awesome parenthood so that my son could be born into this world! Cogmind was essentially the sacrificial lamb, by the way, being perhaps the last such project I'll ever have the concentration of time to undertake in so short a time span. (FYI: Both he and Cogmind were born around the same time.)

**However, there has been a large number of small changes throughout the code responsible for handling object interaction, since that's what this mod is mostly about--increased interaction/dynamic content capable of expressing a greater range of roguelike/RPG features beyond your standard tactical squad simulator.

***And it's not just a few scripts, either. I've churned out a good 5,000 lines of content (hopefully equivalent to "5,000 lines of good content" ;p) in just a few weeks, half of those controlling abilities and interactive environments, in addition to hundreds of new units, many hundreds of items, etc.

Thanks to everyone who voted in the Roguelike of the Year 2012 poll. X@COM did better than last year (all I was hoping for) and we were still in the top 20 despite the inclusion of a greater number of commercial games this year. You can see a rundown of the poll results here as analyzed so nicely by Jo at Rogue Temple. (Cogmind did great, too!)

A little teaser, the intro text for what I'm working on. I wanted to have it ready around mid-December, but I also prefer to include nearly everything in the design doc to retain as much epic potential as possible, and those two goals are definitely at odds with one another. Having no strict deadlines, I made the obvious choice ;p

Mechanics and core content have been finished for a while, but it comes with a huge amount of dynamic content and map areas that have yet to be completed. I'm gradually working down the long list of the latter--eight unique starting areas are already complete, as are two possible boss areas (huge on their own). Then comes several more boss areas and all the little interesting areas in between. Should be fun.

For anyone who didn't read about recent progress, this is the project I was talking about last month (see post), aimed at testing more engine features and making sure it's up to the task of handling all manner of craziness. So far I'm very satisfied, as it is apparently capable of handling a lot of unexpected features.


Also, just like last year, Roguelike of the Year voting has begun. It's not a competition, just an expression of support, so if you like X@COM (and Cogmind for that matter, which was also released this year), head over there and vote for us along with any other roguelikes you've enjoyed this year!

We have our second full mod, this time from Draxis!

Lead a semi-randomly outfitted squad of fully-armed soldiers to take an alien base in Assault. Quite a nostalgic mission, as the design is based on the original alien base assault from X-COM! Most of the gear is standard, though you may have access to the flamethrower as well, which will come in handy if the chryssalids get some of your guys.

Check out some maps generated by Draxis' mod:




I played several games, and in the last was on track to win without losing a single soldier, if not for my own Wolfgang's stupidity. Just before taking the command center the squad used a stolen small launcher to fire back into the darkness from where we were taking heavy fire; advancing forward we found a pile of unconscious snakemen bodies, yay! After everyone passed that spot, Wolfgang decided to do away with the bodies before moving on (didn't want to risk any of them coming to, nor waste time picking up all their weapons). Prime alien grenade for immediate detonation... forget to leave enough time to get around the corner... ka-boom, Wolfgang joins the pile of snakemen bodies.

So... according to the Roadmap I should be working on testing out more facets of the sound support right now.

I'm not.

There are several invisible/unannounced priorities that are injecting themselves into that list, many of them internal changes, the benefits of which may or may not be immediately apparent (to you--I know perfectly well what I'm doing. We hope ;p).

While it seems things have been pretty quiet on my front, it's not for lack of progress, as I've been working on Secret Project No. 47. To put it in non-secret terms, I'm expanding the capabilities of the existing game systems for both better modding potential and more interesting features aimed at the future of X@COM.

Adding official (albeit partial) modding support in R8 turned out to be a wonderful idea, because it'll ensure that at its very core the game supports elements that are both useful and desirable, and that support is built in from the start.

After all, X-COM is not the "goal" of this project; it's merely a starting point. Already we've seen the addition of many elements you won't find in the original, even though for a long time now I've restrained myself from straying too far beyond abstracted recreations of the original mechanics, as I didn't want to get bogged down by the dreaded Feature Creep many epic projects tend to face. (In case you weren't aware, X@COM will be epic, just like you know you want it.)

With the completion of battlescape mechanics in R8, before going much further (i.e., pushing forward with sound and interface development) I'd like to build a stronger foundation for what's to come. Converting armor from a static part of a unit equipped before battle to an item potentially swappable in the field (see earlier post) is representative of the kind of work I'm doing now.

That said, I'm not blindly coding new features here--exploring the possibilities and limits of the game is best done with a usable (and preferably enjoyable) testbed.

Thus I'm guided by design.

Because I'm working on a mod.

Yes, I'm modding my own game :)

It's a rather radical diversion from X-COM, but "diversion" only in the content sense, certainly not the progress sense, as this is indeed expanding the game in some very useful and desirable ways. Project 47 is going to make Cataclysm look like the uneventful sandbox testing map.

There's still much to do because I keep sidetracking myself by coding new features (RL, the non-roguelike variety, is also conspiring to slow me down), but in the meantime, at least one or two more third-party mods will hopefully be ready for you to play around with while you wait for R8.3. And thanks to all current and future modders, who are also helping guide this process by showing me what they want to be able to do, which may or may not yet be available.


I suppose this is really only one part of the Leap, and it's more of a series of skips (but skipping is decidedly non-manly, so we're Leaping), since after this there'll be more intermediary issues I want to tackle before branching off into new areas, but I'll post about those another time.

And we have our first total conversion by Andrew Sundberg! (maker of Cataclysm+)

Take control of a party of orcish raiders as they put the smack down on a human town, or die trying. The party is led by the warlord himself, supported by grunts, archers, a varg, and the oh-so-deadly Elder. Face off against guards, adventurers, mounted knights, mages, monks and more. And don't forget to slay some peasants!

Here is my gang of orcs after having cut a bloody path through the town, now preparing to break into the graveyard crypt to find out what's in those sarcophagi: 


And here were the results of my last test run (I didn't even use my fuming vials!):
Not quite as good as my first run using an earlier version, but Aggression got a bit more difficult since then :)

So go get some Aggression on the files page, and if you'd like to discuss it feel free to join us on Bay 12 or the X@COM modding forum.

This mod wasn't too long in the making--most dev time was consumed by tweaking and balancing, then it sat around in the incubator forum while playtesters gave it a spin (and I've been waiting to upload it since the primary server is down). Expect even greater work from Andrew and other modders in the future!

Note: The primary server is still down, so the site looks a bit weird without its proper fonts and images, including the background image... Downloads are fine though, since I've set up a mirror.

R8 just got a little update, mostly just bugfixes for new features the modders are using, along with a slew of internal tweaks to help them improve existing mods and bring you even better ones.

Of course there is one big change for players: Armor is now an item that can be removed, as described in the previous post. Ctrl-r is the key to both equip and remove armor, which requires two free hands. These actions can also be performed by mouse through the inventory screen. Most of the regular armors are not removable, but for now it'll at least be of some help in Cataclysm since you can pick up bulletproof vests and the like off dead policemen and unique units.

You'll need to grab the new version to play future mod releases, and I updated Cataclysm+ to v3--it's now compatible with 8.1.

Lately I've been reviewing my plan to make mid-mission armor swaps a reality for X@COM, and thought I'd throw my ideas out there to see if any of you have any opinions/suggestions.
I originally didn't bother with this feature since I was trying to keep everything fairly simple and focused on the tactics, so armor currently isn't even represented as an instantiated object in the game. Now I'd like to turn armor into an actual item, mostly intended for mods and special uses, since in a standard X-COM mission your soldiers would obviously be suited up beforehand and are unlikely to have time or reason to swap out while on the ground.

First of all, switching armor shouldn't be as trivial as firing a weapon or sprinting some distance, so it should have a fairly high cost, perhaps 100% TU to remove and another 100% TU to equip, striking a balance between so quick it's unrealistic/too easy and so slow it's annoying/wasteful (the costs are of course adjustable, or even vary by armor type, though probably only in special cases).

For this I'm proposing the addition of "multi-turn actions." Based on this concept, the cost of removal/equipping can be split across more than one turn, thus you can start taking your armor off this turn with your remaining 43% TU, then next turn start with 57% less TU, deducted as the remainder of the previous turn's removal action. This would lessen the impact of the action on a single turn, and not require that you do absolutely nothing else for a given turn in order to complete the action (which could waste a lot of extra TU the turn before). Some special actions added later could also take advantage of the multi-turn system, like hacking an alien computer terminal, which could be set to take 200%, 300%, or whatever makes sense.

The biggest issue with swappable armor is unit representation. Right now armor changes a unit's color, which has worked fine since X-COM soldiers are traditionally the only units with non-racial armor, and a few color shades are enough to effectively convey the difference while still knowing who's in your squad. As alternate armors become more widespread, colors are no longer sufficient to show armors without making the map somewhat more difficult to decipher at a glance, not to mention we'll soon run out of colors. (Even without armor swapping this would become an issue eventually, because I'm not going to stick with the meager three armor types of the original, and many more types of enemies could have armor since there are going to be quite a few possible human factions out there.)

Here in the first two rows are the original unit glyphs, followed by a semi-hollowed test for an armored unit. The third is the less-than-satisfactory result of thinking that an "armored" unit should perhaps have "more" color than an unarmored one, so I thought of switching unarmored units to have a slightly faded outline, and the current full-color glyph represents an armored unit.
It may be difficult to tell whether some of these will work in the game, even more so because they're not colored here, but the glyphs are easy to swap, so we can look at some screenshots later. Should also look into other alternatives. Suggestions?

Another issue is inventory items. Remember (or maybe you didn't know) that armor also provides your non-racial inventory slots; e.g., humans have L/R hand slots, but the rest of their slots come from armor. Equipping new armor would mean you'd have to drop all your items (this could be done automatically for sanity's sake), then pick them all up again and put them in whatever slots your new armor provides. I don't think this is too much of an issue since someone loaded down like that is unlikely to swap armor, plus armor swapping is mostly for mod use, anyway--I envision a character starting with no armor and finding some only later.

This could lead to some interesting gameplay, especially since armor can now provide you with special abilities, so you could equip an exoskeleton that enables you to bash through walls, for example, or a medic suit that comes with a built-in medi-kit, or even armor that automatically heals the wearer. Hell, why not a battlesuit that allows you to chain fire rockets! Okay, getting a bit carried away there... lots of possibilities, anything you can do through the special ability system, really.

EDIT: Nearing the end of my to-do list for the armor-item conversion, and just dropped in some new unit glyphs to test them out in the sandbox (perhaps more appropriately called the grassbox in X@COM):
I like A, the relatively unobtrusive design submitted Shirson. I think I like it better than the more uniform triangle of B. C, the hollow/outline design shown earlier looks pretty cool, but isn't quite appropriate to represent armor. The angular triangles of D/E look too much like L's when diagonal, so they don't work well at all. F, one of the original ideas mentioned, just looks weird. For now I'm probably going to stick with A.
