Math help

I'm looking to build an artillery piece, but I've had a hard time finding the right equation for the job. Can someone help me out here? I'm trying not to use a tutorial. I think the equation has somthing to do with parametrics?

seriously, I have no idea :'(
sounds fun though!

if you tell me what you want your inputs to be and your outputs i can give you the equations. the biggest problem i've found with artillery though is finding a consistent initial velocity, which is vital for artillery.

The equation that i've found so far is s(t)=-16t^2+vo(t)+so. Any ideas how to implement that into wires. I have no programming knowledge so i cant use a cpu or expsresision gate.

Slap on some dynamite and let the Havok engine let it do it for you.

All joking aside, do you wish to set the artillery shell to a specific coordinate or what?

ther did you found? this wat is S, T, SO and VO?
dont know if you can simple use a reallife equation in gmod

it is easy to make a expression gate that calculates this but need to know if SO and VO can be calculatet or are
they simple parameters. are s andt t 3d coords? [S(X|Y|Z)] i guess yes.

You can use this formula that calculates the ange for a balistic trajectory which can be done with normal gates
PS formula made by Pariah not me

Theta = (1/2) * Asin((g*d)/(v^2))

Where:
Theta = Your optimum angle
g = Strength of gravity(in negitive value like on gm_flatgrass it is something like -32)
d = Distance to target
v = Velocity of the projectile as it leaves the barrel (normally found by trial and error(larger value make the impacts move towards cannon and smaller ones move the impact away from the cannon))

these formulas don't account for the air friction barrels experiance in GMOD. Those right there are parabolic curves which BTW unless the barrel is 9999999 weight, it won't fly that path.

realisticly the actual formula is going to look like a SQRT graph for force, a skewed curve for theta. and the coeffecients and values for everything will have to be determined through trial and error

[tomb332]

sorry i didnt know that the equation didnt account for air resistance although it does work with malwar cannons as their projectiles fire in perfect parabolas

thanks alot for the help.
