I've been playing around with GetPlayerSpeed but can't get it realistic in MPH - can someone help? For the record, Infernus should go about 210 MPH

(yay my 900th post)

How could we help you without showing us the code you've made so far?

pawn Код:

stock GetPlayerSpeed(playerid)
{
    new Float:velocity[4];
    if(IsPlayerInAnyVehicle(playerid))
    GetVehicleVelocity(GetPlayerVehicleID(playerid),velocity[0],velocity[1],velocity[2]);
    else GetPlayerVelocity(playerid,velocity[0],velocity[1],velocity[2]);
    velocity[3] = floatsqroot(floatpower(floatabs(velocity[0]), 2.0) + floatpower(floatabs(velocity[1]), 2.0) + floatpower(floatabs(velocity[2]), 2.0)) * 97;
    return floatround(velocity[3]);
}

For the record, the game's files say that the Infernus' max speed is 240 Km/h, which a little more than 149 MPH.

[jameskmonger]

The car is based on this:
http://en.wikipedia.org/wiki/Cizeta-Moroder_V16T
which has a top speed of 204MPH

[iTorran]

204 and/or 210mph is way too high for the Infernus's accurate top speed
What Vince said is a more believable speed for it

[Mike_Peterson]

So, 210 mph is around 340 km/h
On (most) servers, the infernus' max speed is 221 and the LSPD premier is around 177.
177 is 80 percent of 221.. 80 percent of 340 is 272. So, you want a LSPD car go 270km/h..
and what about a tractor? let's say on other servers the speed is 50km/h, which is 22% of 221.
22% of 340 is around 75, now i wouldn't say a tractor (of that model) goes 75 km/h now does it?

Tractors go around 45mph in real life, which is about 70kph

Sure modern tractors go that fast but like mike said

        Float: vY,
        Float: vZ
    ;
    if(_: vX) {
        GetVehicleVelocity(_: vX, vX, vY, vZ);
    } else {
        GetPlayerVelocity(playerid, vX, vY, vZ);
    }
    vX *= vX, vY *= vY, vZ *= vZ;
    return (floatsqroot(vX + vY + vZ) * 200.0);
}

With the multiplier of 200 you get a realistic kmh (~245 infernus top speed), just divide it through 1.61 to get to mph

No, he didn't. 1kph = 0.625mph, so you divide the result to convert it.
