I've read that thread this morning : http://forums.uberent.com/forums/viewto ... 64&t=48314
Of course some people said it was CPU-intensive or whatever to do.
Somebody said it was easy because you already know the vector of the projectile, and he is right.
I though it was a good idea.
On top of it I've said it was trivial to implement into an engine like FA.
And like every time I'm saying something is easy, I do it to prove it, so here is it :
(be sure to look at it in HD and fullscreen, or the particles would impossible to see).
If you like it, well, it's already implemented, I just need to release it.
Personally, I also though FA explosions was lacking some kick, and that kind of directional feel on the blast is quite nice.
