Talk:Exploits

Does anybody mind if I delete the "Extra Ammo" exploit? What is described there, is actually avoidance of a glitch, not an Exploit. And it's already described under Known_Bugs#Disappearing_Ammo. I'm about to flesh out the Glitch, and it's annoying to have to repeat in two places when the second's not really an Exploit. I'll do it in a week if nobody objects. If somebody objects, it stays. ---MikeTheRed 13:35, 11 December 2005 (PST)

Repairing damaged UFOs

Want to stop a UFO from doing it's mission? Shoot it down. Want to get a full load of engines and elerium? Leave it alone for about 2 days. The longer you wait before launching the ground assault, the smaller the hole and smoke, and eventually the craft will be completely repaired.

Note that you will also get a full complement of enemy soldiers -- all the dead will come back to life when you do this.

(You may want to save the game before landing, so you can resume waiting if the UFO was not fully repaired when you attacked.)

Actually, UFO damage is random. You see, the damage done to a UFO in the battlescape is caused by the game detonating the power units with varying detonation strengths every time the map is generated. Sometimes it's only strong enough to destroy the power unit, and if there are many power units, some of the might not even be detonated at all. So there's no wait, just save the game in the Geoscape, and enter the mission. If the damage is not to your liking, reload and try and try again until you get a favourable outcome. - NKF

Keybouncer and NKF, you've both tested this likelihood versus time? Seems easy enough to do. Two related questions (have they been answered here?): 1) How long do crash sites persist?, and 2) If one Power Source (PS) blows up, yes, it will destroy E115 within a particular distance, but will it cause them to explode?

The reason I ask is that page 311 of the OSG says PSs have a 70% chance of exploding, which sounds about right to me. A table of probabilities of finding intact PSs for the various UFOs could be generated. I would have thought the answer to #2 is that they don't cause them to explode; they're not an explosive object. But in my experience, the ground floor of a Terror Ship is always the same - all four PSs are always blasted up, and the surrounding interior walls are always in the same bad shape (i.e., they're always all gone, except by the door at the south).

Anyway, a probabilistic thing would be fun to do. But the question of successive explosions has been puzzling me. Could E115 trigger something special in crashes? (Successive explosions even though it's not registered as an explosive?) E115 has always had that odd boolean checkmark at OBDATA.DAT[45]. - MikeTheRed

While I have not collected large amounts of data to show any pattern in the extent of the damage vs time, I haven't really seen any difference in damage between the moment the crash site was created or at a point just before the crash site vanishes. It's roughly the same and varies from game to game. If the UFO is repaired over time, this information will have to be stored somewhere. Craft.dat or loc.dat are probably the most likely files to watch. As for the explosions - I guess during the pre-detonation stages, the game may take into account nearby power units that get caught in the blast and detonate them as well. The 70% chance still holds true for isolated units. Can we add extra power units to the existing craft maps to test this I wonder? Or what about setting this boolean flag for enemy corpses, and crossing our fingers? Heh. That might not work. - NKF

Hehe, it might be fun to play with those booleans. Or not. ;)

I wouldn't think info has to be stored anywhere; after all, the crash site is not created unless/until you fight it. (If I remember right.) If it does "repair", it could simply be based on the time since the crash... and I guess this would basically equate to, a lower probability of PS explosion. FWIW, I never had the impression that more time meant less damage, but then I wasn't paying attention to the possibility.

I guess that, since PS explosions are performed by code that is "above" normal battlescape properties (i.e., PSs are not explosive per se), it's entirely possible they also programmed in, that they trigger successive detonations. It could be fairly easily tested, in theory... There are only 3 UFOs where PSs can "interact": Harvester (2 PSs), Supply (3), Terror (4). Supply UFOs might be the most interesting in terms of teasing out whether there are successive detonations. FWIW, straight odds (no interaction) of having 2 PSs intact is 9.00% (.3²), 3 intact is 2.70%, and 4 intact is 0.81%.

Remind me, is there some quick way to "lift the fog of war" and see the whole map? Maybe with Mapview? (I don't have it installed ATM; I recently got a new PC.) If so, it would be fairly easy to see e.g. if terror ships ever vary their explosion pattern, etc. Also any differences between combat early or late after a crash.

Maybe we should move all these comments, maybe even this whole section, to Discussion? - MikeTheRed 17:43, 10 January 2007 (PST)

Moved - and discussions split up and line breaks inserted for your reading convenience. Coincidentally, Mike, it has been a while, but I'll let you decide what to do with your earlier comment up above.

As for the maps - I know XComutil has an option to clear the fog of war and make everyone on the map visible (and sets the lighting for the whole map to the brightest setting until you move). Use the command line utility's VIS command. Like so: xcomutil game_n vis wrt - game_n being the directory for your tactical savegame.

Or the time left until the crash site disappears. That is almost certainly in the savegame, and would be worth mapping in its own right.
