pawn Код:

stock GetPosFromView(playerid, Float:distance, &Float:x, &Float:y, &Float:z)
{
  new Float:cx,Float:cy,Float:cz,Float:fx,Float:fy,Float:fz;
  GetPlayerCameraPos(playerid, cx, cy, cz);
  GetPlayerCameraFrontVector(playerid, fx, fy, fz);
  x = fx * distance + cx;
  y = fy * distance + cy;
  z = fz * distance + cz;
}

I couldn't think of other name..
This function returns coords of the point a player is looking at, depending on the distance.

Example:

pawn Код:

zcmd(bang,playerid,params[])
{
  new Float:r;
  if(sscanf(params,"f",r)) {}
  else
  {
    new Float:x,Float:y,Float:z;
    GetPlayerPos(playerid, x, y, z);
    GetPosFromView(playerid, r, x, y, z);
    CreateExplosion(x, y, z, 2, 10);
  }
  return 1;
}

If you type /bang 20 there will be an explosion 20 gta units far from you.
