Finally the Velocity functions are here.

Код:

stock GetPlayerSpeed(playerid,bool:kmh) // by misco
{
  new Float:Vx,Float:Vy,Float:Vz,Float:rtn;
  if(IsPlayerInAnyVehicle(playerid)) GetVehicleVelocity(GetPlayerVehicleID(playerid),Vx,Vy,Vz); else GetPlayerVelocity(playerid,Vx,Vy,Vz);
  rtn = floatsqroot(floatabs(floatpower(Vx + Vy + Vz,2)));
  return kmh?floatround(rtn * 100 * 1.61):floatround(rtn * 100);
}

(edited)
Example usage:

Код:

if (!strcmp("/myspeed", cmdtext, true))
	{
		new str[128];
		format(str,128,"My speed is %d km/h and %d mph !",GetPlayerSpeed(playerid,true),GetPlayerSpeed(playerid,false));
		SendClientMessage(playerid,0xFFFFFFAA,str);
		return 1;
	}

Returned values seems real.

Good job.

Is x,y and z in meters or what?

[[NL]Bank]

hmm, very nice.

[Fireburn]

Can I ask why you are doing the floatsubstraction? You're substracting it with nothing so that doesn't make any sense does it?
Anyways, looks nice.

Probably the gta metric system, SetPlayerPos( playerid , 0.1 , 0.1, 0.1);

[ғαιιοцт]

I already had this in my speedometer, but the calculation works a little different

this is a lot better than with GetPlayerPos

[Rac3r]

Yes.

Question : If you drive off a cliff and fall, does the function return the actual speed the vehicle is falling at, or does it return the speed the engine is reving at?
If I had SA-MP I would try myself.

The speed that it is falling at.

It has something to do with distance calculation. My bad. You can edit it for yourself ill change it tomorow. Thanks for attention.

I prefer my own GetPlayerSpeed...^^

What might be the difference ? there is only one math way to get the result speed anyway. Probably different names of varibales ? lol

[Double-O-Seven]

I mean I do not use GetVehicleVelocity to get the players speed because I don't know how to get the speed correct... Is the x, y and z meters/second or km/h for each direction or what?

Yeah, would be good to know what unit it uses.

[Westie]

I thought GTA:SA units were meters? I'm slightly retarded.

Yeah, good job, but... redundant code?

Kinda.

[Zeex]

Why do you use "floatabs"? Squared value is ALWAYS positive!

pawn Код:

floatsqroot(Vx*Vx + Vy*Vy + Vz*Vz);

^ Looks more easier and does the same thing.

OK, look into float.inc and you will see:

pawn Код:

native Float:operator*(Float:oper1, Float:oper2) = floatmul;
