About muzzle velocity and ammunition

[tateyou]

Here is the thing, i'm working on creating a railgun, so is there a possibility that i could set the value of muzzle velocity, and creat a new type of ammuntion, instead of the original types in ARMA?
For example, a railgun can accelerate it's own bullet to 3000m/s, how can i do that?

You can do this very easily by changing the initSpeed value in the cfgMagazines.  I don't know if the ArmA engine could handle speeds of 3000 m/s.

You could do this very easily in script only with a fired event handler. Add this to the unit's init line:

Code: [Select]

this addEventHandler ["FIRED", {[_this, 3000] call fRailgun}];add this to your init.sqf:

Code: [Select]

fRailgun = compile preprocessFileLineNumbers "railgun.sqf"
and add the following script to your mission folder:
railgun.sqf

Code: [Select]

private ["_bullet", "_initSpeed", "_vel", "_velSqr", "_ratio", "_velRail"];
_bullet = nearestObject [_this select 0 select 0, _this select 0 select 4];
_initSpeed = _this select 1;
_vel = velocity _bullet;
_velSqr = 0;
{_velSqr = _velSqr + (_vel select _x)*(_vel select _x)} forEach [0, 1, 2];
_ratio = _initSpeed / (sqrt _velSqr);
_velRail = [];
{_velRail = _velRail + [_ratio * (_vel select _x)]} forEach [0, 1, 2];
_bullet setVelocity _velRail;

Thanks a lot, but is there a way to creat an independent PBO instead of using in mission?
