How to get symmetrical midair explosions for planes
« on: May 22, 2014, 06:39:06 AM »

The effects mods I've used so far have had a problem which bugged me. Planes exploding in the air *always* had their blasts directed toward the east, no matter their attitude or direction of travel. It's just like detonating a bomb planted on an east-facing wall, or cliff.

This happens when the effect's emission of particles is constrained. To ensure the blast is symmetrical, make sure the values are:

EmitTheta 0.0 180.0 (if the parameter is in degrees, which I doubt but do use), or
EmitTheta 0.0 200.0 (if in gradians, which I think is really the case.)

This will emit particles over a full sphere (or over ~340 of 360 degrees in my case, if gradians is indeed the angular measure.)

Originally I would find something like:

EmitTheta 0.0 20.0

This tightly constrains particle emission to within only 20 grad of the reference axis (which for airbursts is directed horizontally toward the east.) VERY ODD for exploding planes, certainly if heading west. ;)

The effects to check, in 3do/Effects/Fireworks/:
Tank_Burn.eff (makes fireball)
Tank_SmokeBoiling.eff (makes smoke cloud)
Tank_Sparks.eff (generates glowing particles flying outward)
Tank_SparksP.eff (generates opaque particles flying outward)

Naturally, other parameters should be tuned so as to suit a spherical instead of a directed blast...

i'm not too up to date with these effects files, but i suspect that, because so many files are shared between air and ground explosion/smokes, that some would have to be like this in order to have a 'column' of smoke, as opposed to a round blob of smoke from a burning tank, for instance.
experimentation, and through that, education, is always a good thing, so this info is always appreciated.
then again, it would be awesome if we could introduce new effects into the game, besides those we already have. coding, anybody? ... :D

I'm using 0.0 180.0 for years and it works.
Another way to make the same effect is to use 0.0 90.0 but with velocity something like -50.0 50.0.
The only difference is that the particles will concentrate more in the center of the explosion.
