except in an electron laser : ). but that requires electromagnetism not wind, which brings me to my next point, lets add magnetism. that would be cool. but then again, it would be hard to do.
I have my doubts about the thunder as well. Currently it is more a bomblet than thunder. I like 'bomblet', even though it is a bit overpowered.
A thunder element would (for me) be * fast travelling (like plutonium/uranium), but not only falling. It could behave like a slower photon, radiating in all directions. After all, many flashes in a thunderstorm actually travel upwards. * not reacting to wind * if possible, attracted to metallic elements * it would create pressure all the time (you end up with a 'pressure path'), just like a real flash.
As I said, I like 'bomblet', keep it! Create a new element called flash
By the way: I am so happy that someone took over the powder game. Thanks, Simon, for your furious work to take the powder game to a new level!
Ah, very quick idea: As Thunder generates a hilarious pressure, it would be nicer just to receive a short pressure front. After explosion of a lightning particle, the pressure could be very strong for two frames or so, after that the same pressure difference in the opposite direction would deliver a sharp front, without air actually being added. This would be quite realistic (and would probably look very nice). Again, the current thunder particle behaves correct if understood as a bomblet, creating a huge amount of air. (Still overpowered, though).
