[SnL]

How i can solve this warning ?

Code:

C:\Users\ZombieLand\Desktop\Servidor\gamemodes\RNPCPRUEBA.pwn(33) : warning 235: public function lacks forward declaration (symbol "Follower")

Code:

stock FollowPlayer(npcid, targetid)
{
    SetTimerEx("Follower", 500, 1, "ii", npcid, targetid);
}

public Follower(npcid, targetid)
{
    new Float:x, Float:y, Float:z;
    GetPlayerPos(targetid, x, y, z);
    MoveRNPC(npcid, x, y, z, 0.006);
}
