3D explosions

[Daiky]

I always found it curious how explosions are confined to one level. I'm suggesting (to myself) making an option that the explosion affects a sphere-shaped area. Also for smoke grenades (smoke being blocked by floors and ceilings of course). Incendiary probably has not a lot of spreading upwards, as it is more affected by gravity, so I'm leaving that as it is.

What about creating creaters in ground? But that probably would require much additional work (like negative levels).

[hsbckb]

I strongly agree that explosions should be multi-leveled. Negative level(i.e underground level) is a must, especially for Alien Grenade.

However, we must teach our operative how to climb out from the hole 

[Daiky]

Personally I shouldn't even make it optional... but seeing it as a "bug" fix.

Negative ground level is something that can be more or less be supported. It's more a matter of remaking all maps, moving everything up one level and filling level 0 with ground.
But as hsbckb said, it will create 1-man deep craters with vertical walls you can never get out once you fall in :p

I was thinking the same thing the other day

I would call this a bug fix

But as hsbckb said, it will create 1-man deep craters with vertical walls you can never get out once you fall in :p

No problem, just equip your soldier with "portable ladder"

But really, what about creating craters with diagonal walls? Like in mountains or dunes.

[Daiky]

real craters with diagonal walls? I don't know, what if two craters overlap eachother and then still have to create very smooth edges... my brain hurts just thinking about it.
Just let the scripting fans code such terrain deformation algorithms in lua or python :p

[hsbckb]

Actually, negative level exist in game. In desert area, there are sand dune with surface at level 3 or 4.  We can activate a grenade there to see how the original game handle this situation.

Even more interesting to simulate explosion wave. And explosion will not be always round, but will follow geometry of the map.

[Daiky]

I don't know what you mean with explosion wave? Initial blast is round, but it's path can be blocked by objects (they have a HE block modifier) but that's already implemented and working.

[Volutar]

Actually explosions are multileveled, but implemented weirdly. Anyways explosion wave shouldn't be "spherical" just because of 3d proportion. Level height is 24 and tile size is 16. So it should be slightly "squeezed" vertically. But I think it should be squeezed even more. Probably variable value.

[DiceMaster]

I mean spreading and reflection of blast waves. If grenade explodes in closed room, then explosion pressure on walls and objects inside room will be higher than in open air. Explosion in a corridor will spread farther, e.t.c. Something similar I saw in Dungeon Crawl Stone Soup for aoe spells.

Does openX only support 4 levels or can we go higher ?

[Daiky]

It should be unlimited
