NPC_Event: event not found

[Genesis]

Hello,

 

With the following script:

pvp_n_1-1,0,0,0,0       monster Poring  1002,90,0,0,"SpeedRoomChecker::OnKill";
 
 
-       script  SpeedRoomChecker        -1,{
OnKill:
        if (countitem(617) < 1) {
                mes "You have 0 apples!";
                warp "prontera",0,0;
        end;
        }
end;
}

I am getting this error message:

[Error]: npc_event: event not found [SpeedRoomChecker::OnKill";;]

I'm not sure why, I have worked on similar scripts with minimal problems. I assume this issue is something rather silly I am missing. Any thoughts?

open "rathena\npc\script_custom.txt"

 

then add this

 

npc: npc/custom/npc_event.txt
