XY infront of player - pagie1111 - 19.10.2009

Hello. Someone ages ago gave me this function:

pawn Код:

stock GetXYInFrontOfPlayer(playerid, &Float:x, &Float:y, Float:distance)
{

    new Float:a;
    GetPlayerFacingAngle(playerid, a);
    a -= 90;

    y += (distance * floatsin(a, degrees));
    x += (distance * floatcos(a, degrees));
}

but no matter where i am or which way i am facing it always points to the north area OFF the map :S. even with 5.00 distance.

Help it muchly apprectiated.

I hope that will make it work. If it does, you have just helped Enemy Plus fix the biggest bug in our scripts

and you will make me very happy.

Didnt work. Bummer. Anyone else?

Show us where you use it (code snippet).

Also before you do that, make sure you are passing a 'Float' type as the distance, if you mess up the types and push an integer then it will be a huge distance.

        else
        {
          SendClientMessage(playerid,MAROON,"Airstrikes not available");
        }
        return 1;

new Float:PX, Float:PY, Float:PZ;
