Step 1:
Go into your Packet Handler Folder.
Add this:*CHANGE THE IMPORTS TO YOURS*
Name it: NPCOption3.java

Code:

import net.com.codeusa.util.Misc;

public class NPCOption3 implements Packet {

    public void handlePacket(Player p, int packetId, int packetSize) {
        if (p == null || p.stream == null) {
            return;
        }
        if (!p.npcOption3) {
            int npcId = p.stream.readUnsignedWordBigEndian();
            if (npcId <= 0 || npcId >= Engine.npcs.length || Engine.npcs[npcId] == null) {
                return;
            }
            p.clickId = npcId;
            p.clickX = Engine.npcs[npcId].absX;
            p.clickY = Engine.npcs[npcId].absY;
            if (Misc.getDistance(p.absX, p.absY, p.clickX, p.clickY) > 30) {
                return;
            }
            p.npcOption3 = true;
        }
        if (p.clickId <= 0 || p.clickId >= Engine.npcs.length || Engine.npcs[p.clickId] == null) {
            p.npcOption3 = false;
            return;
        }
        if (Misc.getDistance(p.absX, p.absY, p.clickX, p.clickY) > 1) {
            return;
        }
        p.npcOption3 = false;
        switch (p.clickId) {		
        default:
			Misc.println("[" + p.username + "] Unhandled npc option 3: " + p.clickId);
            break;
        }
    }
}

Step 2:
Open up PacketManager.java
Search for:

Code:

public NPCOption2 npcOption2 = new NPCOption2();

Under it, add:

Code:

public NPCOption3 npcOption3 = new NPCOption3();

Step 3:
Search for:

Code:

case 52:

You should see:

Code:

case 52:
            /*
             * Second NPC option.
             */
            npcOption2.handlePacket(p, packetId, packetSize);
            break;

Under it, add:

Code:

case 199:
            /*
             * Third NPC option.
             */
            npcOption3.handlePacket(p, packetId, packetSize);
            break;

Step 4:
Open up Player.java
Search for:

Code:

public boolean npcOption2 = false;

Under it, add:

Code:

/**
     * Clicked the third option on a NPC.
     */
    public boolean npcOption3 = false;

Step 5:
Search for:

Code:

if (npcOption2) {

Under:

Code:

if (npcOption2) {
            Engine.packets.npcOption2.handlePacket(this, 0, 0);
        }

Add:

Code:

if (npcOption3) {
            Engine.packets.npcOption3.handlePacket(this, 0, 0);
        }

Step 6:
Search for:

Code:

npcOption2 = false;

Under it, add:

Code:

npcOption3 = false;

There you go.
