Matthijs 40 Posted March 13, 2002 Hi, I am currently working on a script for indirect fire (artillery). To accomplish this I need some information. I hope someone here can help me out... - What is the gravity in OFP in meters/second square? (m/s^2) - What is the velocity of an M60 tank shell in OFP in meters per second? (m/s) - Does a shell decellerate as a result of air friction? (yes/no) (OFP figures, not real life figures plz) Kind regards, Matthijs Share this post Link to post Share on other sites
sgt bastard 0 Posted March 13, 2002 It's probobly only the BIS team who knows. But why don't you do your own experiments? Like let an object fall from a known height and take the time. Take time between firing the M60-tank and impact of the shell. Share this post Link to post Share on other sites

Take time between firing the M60-tank and impact of the shell.<span id='postcolor'> Yes, I was planning to do that. But nothing beats knowing the real figures. I was only hoping for someone who knows the exact numbers to read this thread. Thanks for the input anyway. Ever tried to do artillery using tanks? It really beats spawning some shells in mid-air. You can actually hear the shells flying over your head. It's also a nice passtime to try the range at different inclinations. (I myself in a chopper, ordering a tank to fire away at 2,3 degrees inclination... soooooo cool... ) Share this post Link to post Share on other sites

Matthijs 40 Posted March 13, 2002 Wow... OFP is far more accurate than I actually thought it would be... NICE! Hey Suma, uhm, sorry about my the outburst some time ago... (about Oxygen). I wanna take the opportunity to take back what I said about you guys. Good luck programming some more. Share this post Link to post Share on other sites
