Hey, what's up?
I'm having troubles with calculation a vehicle's speed in KM/h.. I really can't do it :S
I'd appreciate if you'd help me, or give me a function/stock that calculates it.
Thanks !

I'm not going to include this whole include for just a textdraw..

Код:

(((x ^ 2) + (y ^ 2) + (z ^ 2)) * 100) * 1.6)

That's the formula for calculating speed in kilometers, where x,y,z is the current velocity of the player in each direction.

You could download the include and see in the source the calculation, but JatochNietDan already post it.

Thanks. It should return it as an int or float?

Float, convert to INT if needed.

floatval()

Actually, * 1.6 Isn't working the right way.

*187.666667 would work better.

I did this:

pawn Код:

format(str, sizeof(str), "KM/h: %d", GetVehicleSpeed(0));
SendClientMessage(playerid, 0xFFFFFFAA, str);

stock GetVehicleSpeed(vehicleid)
{
    new Float:v[3];
    GetVehicleVelocity(vehicleid, v[0], v[1], v[2]);
    return (((v[0] ^ 2) + (v[1] ^ 2) + (v[2] ^ 2)) * 100) * 187.666667;
}

But it gives me those errors:

Код:

vb-livecam.pwn(229) : warning 213: tag mismatch
vb-livecam.pwn(229) : warning 213: tag mismatch
vb-livecam.pwn(229) : warning 213: tag mismatch
vb-livecam.pwn(229) : warning 213: tag mismatch

Line 229 is this:

pawn Код:

return (((v[0] ^ 2) + (v[1] ^ 2) + (v[2] ^ 2)) * 100) * 187.666667;

But if I won't use the "format" I won't get any warnings.

Try this:

pawn Код:

stock GetVehicleSpeed(vehicleid)
{
    new Float:V[3];
    GetVehicleVelocity(vehicleid, V[0], V[1], V[2]);
    return floatround(floatsqroot(V[0] * V[0] + V[1] * V[1] + V[2] * V[2]) * 180.00);
}
