Good idea Monk, but all that is a little out of my league.
from wikipedia -
Paintball Velocity - In addition to the mandatory use of masks, paintball markers must not fire paintballs that exceed a certain velocity. The industry standard maximum velocity is 280 feet per second (about 180 miles per hour). Paintballs traveling faster than 300 ft/s (90 m/s) will leave large bruises and can potentially break the skin or even fingers. Many commercial paintball facilities mandate a lower velocity, usually 250 to 295 ft/s (75 to 90 m/s) in order to create an extra margin of safety. Lower velocities can still be painful at point blank range, and should be avoided when possible. Players sometimes wear thick jackets and gloves to cover any exposed skin.
The game engine seems to run on meters. If you notice, for low grav, you only notice changes if you set the gravity above or below -9.8. The reason is that 9.8 meters per second squared is the pull of gravity, and the negative means down (I once tried to change gravity with a positive number, I floated up
). I am an AP Physics nerd (so you don't need to ask).
Anyway, if 90 m/s is the industry maximum for paintball speeds, for ease of game purposes, I made it 100. I did that because I was too lazy to convert from the feet per second and approximated it. If you notice, when you watch paintball tournaments on TV, you can see the paintballs flying. 1000m/s is comparable to the 975 m/s velocity of a real M16 rifle, but paintballs are propelled by Carbon Dioxide (or other gases), not explosions in real bullets. Alright, enough physics, I have...physics homework to do (seriously
).
