GetPosInFrontOfPlayer(playerid, Float:distance, &Float:x, &Float:y, &Float:z)
{
if (GetPlayerPos(playerid, x, y, z)) // this functions returns 0 if the player is not connected
{
new Float:z_angle;
GetPlayerFacingAngle(playerid, z_angle);
x += distance * floatsin(-z_angle, degrees); // angles in GTA go counter-clockwise, so we need to reverse the retrieved angle
y += distance * floatcos(-z_angle, degrees);
return 1; // return 1 on success, the actual coordinates are returned by reference
}
return 0; // return 0 if the player isn't connected

warning
GTA/SA-MP use degrees for angles in most circumstances, for example GetPlayerFacingAngle. Therefore, it is most likely you'll want to use the 'degrees' angle mode, not radians. Also note that angles in GTA are counterclockwise; 270° is East and 90° is West. South is still 180° and North still 0°/360°.
