Speed in KMPH - Virus. - 18.11.2012

Hello guys.

Код:

GetVehicleVelocity(GetPlayerVehicleID(x),X,Y,Z);
		new Float:temp=floatsqroot((((X ^ 2) + (Y ^ 2) + (Z ^ 2)) * 100) * 1.6);
		new kmph[80];
		format(kmph,sizeof(kmph),"Speed : %i KMP/H",temp);
        TextDrawSetString(speed[x], kmph);

I am not getting the speed in KMPH. It shows a very big number even when the vehicle is not moving.

The circumflex character (^) isn't the power operator in Pawn, it is the bitwise XOR operator. The right formula is:

pawn Код:

floatsqroot(((x * x) + (y * y) + (z * z)) * 195.12)

Re: Speed in KMPH - Virus. - 18.11.2012

tht gives 0 KMPH when the vehicle is not moving and when it starts moving it gives a very big number. Is floatsqroot required infront of it??

Yes. Sorry, forgot.

Re: Speed in KMPH - Virus. - 18.11.2012

I get this speed.

Usually happens when you try to print a float as an integer.

I had the same 'issue' when I was creating my own. Use floatround to round up/down and then display it as an integer.

Do you mean, that it should be printed as a float, because he's using it as an integer.

pawn Код:

format(kmph,sizeof(kmph),"Speed : %i KMP/H",temp);

He means that either you have to:

A) Display it as a float (horrible idea for speed-o-meters)
B) Use floatround, and get it into integer form and THEN display it

Re: Speed in KMPH - Konstantinos - 18.11.2012

It can be done as a float without the rest after the dot '.'

pawn Код:

%.0f

If it's 12.45676, it'll display 12!
