UFO Power Source Explosions: Elerium spawning

	::I can shine some light onto the GZ+12 question, because I just yesterday recovered Elerium from a Supply Ship with two destroyed power sources. Blaster Bomb explosions propagate for 11 tiles, and have no power after that, and tests have shown that a PS explodes with the same force as a BB. As well, it should be noted that sometimes the location of the PS starts on fire and may remain so for some time. (On one final note, it makes more sense to me that Elerium is spawned under SURVIVING power sources; so there is no chance that it is destroyed by an explosion; it spawns after the explosions occur. Of course, I could be completely wrong, it just makes more sense to me to code it that way.)

			:::I was just playing around a bit, and changed Elerium's explosion resistance to 255. No Elerium spawned under exploded PSes that I could see, but I only did a mission or two that way so far. Further testing obviously needed, but some form of automation would be nice. Of course this lets you get away with using grenades within engine rooms, but otherwise UFO Crash Recovery numbers remain unchanged.[[User:Epiceuropean\|Epiceuropean]] 12:07, 11 January 2010 (EST)

	:Good point Arrow, thanks for that. Zombie, I've got a handle on it again and will post something about expected number of PSs at crash sites, a.k.a. average Elerium recovered. E.g. Supply ships yield 17.7 units of Elerium, on average (calcs to be shown on wiki). One thing has me curious... in your XCOMUFO thread you say you wrote down the edge strength of PS blasts (35 to 70) but then later said there are 71 possible values. But aren't there actually only 36? And again I wonder if truncation might have something to do with it... see, depending on just how they truncated what was applied (if they did) and/or how BB's tiles show the number, could have caused a fair amount of creep one way or the other... and it looks like it crept up. (''If'' there were 256 original values somewhere/somehow which got converted to a 7th as many someway/somehow (36/256) ... shrug.) But it's really only an incredibly minor issue. .... Anybody care to recommend where I'd post the info on Elerium salvage? [[UFO_Crash_Recovery]] makes a lot of sense conceptually, but it's not a particularly info rich page. - [[User:MikeTheRed\|MikeTheRed]] 18:58, 10 October 2007 (PDT)		:Good point Arrow, thanks for that.

	OK that makes sense. With the Desert Base armour at 5, any residual HE effect below 10 would have no effect on the terrain. It does suggest that the HC-HE radius 4, HE=12 is definitely crimped off, since HE=12 would be enough to damage the tiles at radius=4. But I suppose it's ''possible'' that the AC-HE radius 4, HE=4, is still present but undetected on the desert tile map. Since it does a maximum of 6 damage, you would very rarely see damage even to a unit. But unless the AC-HE is less constrained than the HC-HE, which would make no sense at all, there is no effect at all from AC-HE at radius=4 - not even against units.

	:Well, I'm using unaltered desert terrain which has 0 HEB, 5 "Base" Armor and 25 "Death" Armor. Suppose I could use Bomb Bloke's numerical testing tileset for this as his armor strengths are all custom edited and have numbers to show tile damage. But, I might just use my flat terrain map pack and edit the MCD values so that everything is 0. Still, terrain shouldn't have any effect on damage to units in an explosion if the ground tiles have 0 HEB as this lets the explosion go past unhindered (except for distance of course). Armor only determines when a tile sprite should change it's appearance. Not too sure of the exact reason why the explosion doesn't go out further than what is expected though. My only guess is that integer rounding plays a pretty big role here and it may be negating the propagation when the damage gets below 10 Average (or 5 for the min?).

	::I can shine some light onto the GZ+12 question, because I just yesterday recovered Elerium from a Supply Ship with two destroyed power sources. Blaster Bomb explosions propagate for 11 tiles, and have no power after that, and tests have shown that a PS explodes with the same force as a BB. As well, it should be noted that sometimes the location of the PS starts on fire and may remain so for some time. (On one final note, it makes more sense to me that Elerium is spawned under SURVIVING power sources; so there is no chance that it is destroyed by an explosion; it spawns after the explosions occur. Of course, I could be completely wrong, it just makes more sense to me to code it that way.) [[User:Arrow Quivershaft\|Arrow Quivershaft]] 16:16, 9 October 2007 (PDT)		::I can shine some light onto the GZ+12 question, because I just yesterday recovered Elerium from a Supply Ship with two destroyed power sources. Blaster Bomb explosions propagate for 11 tiles, and have no power after that, and tests have shown that a PS explodes with the same force as a BB. As well, it should be noted that sometimes the location of the PS starts on fire and may remain so for some time.

			:::I was just playing around a bit, and changed Elerium's explosion resistance to 255. No Elerium spawned under exploded PSes that I could see, but I only did a mission or two that way so far. Further testing obviously needed, but some form of automation would be nice. Of course this lets you get away with using grenades within engine rooms, but otherwise UFO Crash Recovery numbers remain unchanged.[[User:Epiceuropean\|Epiceuropean]] 12:07, 11 January 2010 (EST)

	:Good point Arrow, thanks for that. Zombie, I've got a handle on it again and will post something about expected number of PSs at crash sites, a.k.a. average Elerium recovered. E.g. Supply ships yield 17.7 units of Elerium, on average (calcs to be shown on wiki). One thing has me curious... in your XCOMUFO thread you say you wrote down the edge strength of PS blasts (35 to 70) but then later said there are 71 possible values. But aren't there actually only 36? And again I wonder if truncation might have something to do with it... see, depending on just how they truncated what was applied (if they did) and/or how BB's tiles show the number, could have caused a fair amount of creep one way or the other... and it looks like it crept up. (''If'' there were 256 original values somewhere/somehow which got converted to a 7th as many someway/somehow (36/256) ... shrug.) But it's really only an incredibly minor issue. .... Anybody care to recommend where I'd post the info on Elerium salvage? [[UFO_Crash_Recovery]] makes a lot of sense conceptually, but it's not a particularly info rich page. - [[User:MikeTheRed\|MikeTheRed]] 18:58, 10 October 2007 (PDT)		:Good point Arrow, thanks for that.
