[request] Aircraft destruction; visual mods - SquidgyB - 22.02.2009

Hello there, and firstly I must thank and congratulate everyone on their hard work, IL2 wouldn't be anything near as dynamic and interesting as it is right now with all the effort that has been put into the additions available here.

I have two "requests", or rather topics of discussion as to whether these are at all possible, or if they would require such a large effort of changing the base code in IL2 as to be difficult or impossible to implement.

I'll start off with what I'd consider to be the "easier" of the two;

When an aircraft is destroyed while in flight (by explosion or crash) the edges of the pieces it falls into are rather too well defined, like a Lego model being broken apart. What I was wondering was if there's a way of using a seperate set of textures for this "state" of the models, so that the edges are frayed/torn/broken, and above all not a straight, sharp line.

Secondly, and what I believe to be something you'd really have to dig deep into the code to change; When the said pieces of the aircraft fall, they all seem to have very much the same momentum, and the "ark" of the pieces as they fall, though spread horizontally, to me feels a bit too pre-defined, if that's the right word. I haven't looked at any authentic footage or anything, but I would have expected the spread of pieces to be a little more chaotic. You can see what I mean particularly when an aircraft is blown up above water, as most of the pices hit the water at almost exactly the same time, where I'd expect the large pieces of wing etc to flutter a bit more, and the engines to go down, well, like a lead weight.

Anyhow, just a couple of things I thought would add to the immersion, and I'm not at all sure if any of these are possibilities.

Don't forget that when something falls no matter the mass they land at the same time if dropped from the same altitude. This speed is the acceleration of Gravity which is 9.81m/s squared.

so after about 5 - 10 seconds of free fall they travel at the same speed. This does not take into consideration the shape of the object as that has todo with air resistance not gravity.

and now we know.

Granted, I understand the physics behind gravity, but like you said, that doesn't take into account drag caused air resistance, which on a large open area like a wing will be a lot more than on a solid object like an engine.

I was thinking that a calculation of momentum based on area like that would require a hefty amount of extra code, where the effect I'd like to see might be acheived by varying the speed of each object, just giving each one a %age deviation from what they have now.

In any case, I'd probably consider the first mod request, texturing of the broken pieces as something that would increase immersion for me more than the bits falling in that way.

e: and having thought of it, the air resistance would have a much more profound effect on the forward motion of the pieces, slowing the larger/lighter pieces down and causing them to have a much more vertical drop than the heavier lumps which would carry on without much resistance... maybe.

probably be easier to just give each big piece a specific set speed (non varying) so that it won't take up much coding.

P.S. I don't even know if it's possible
