Adding a Easy-To-Use Dialogue (NPC/Player) System

~Lester Knome's Easy-To-Use Tutorials~


MAKE SURE YOU MAKE A BACKUP

I made this after i saw what rog3r made xD (He had a mistake in his coding, but let's let lil rog3r figure it out.)

First save this to Dialogue.java:

Code:

---

public class Dialogue {
       
        public void npcChat(int ID) {
       
                client c = (client) server.playerHandler.players[ID];
               
                /*Npc Chat*/
               
                switch (c.NpcDialogue) {
               
                        /*
                        Example:
                        case 1:
                                npcChat("Oman dis nice", 454);
                                nextChat(2);
                        break;
                       
                        case 2:
                                npcChat("Bai Bai", 454);
                                nextChat(-1);
                        break;
                        */
               
                }       
        }
       
        public void option1(int ID) {
       
                client c = (client) server.playerHandler.players[ID];
               
                /*option1 for Choice*/
               
                /*
                Example:
                if (c.NpcDialogue == 2) {
                        c.sendMessage("Hi :D");
                }
                */
       
        }
       
        public void option2(int ID) {
       
                client c = (client) server.playerHandler.players[ID];
       
                /*option1 for Choice*/
               
                /*
                Example:
                if (c.NpcDialogue == 2) {
                        c.sendMessage("Bye D:");
                }
                */               
                       
        }
       
        public void playerChat(String text) { // Player talking.
                client c = null;
                c.sendFrame200(974, 595);
                c.sendFrame126(c.playerName, 975);
                c.sendFrame126(text, 976);
                c.sendFrame126("", 977);
                c.sendFrame185(974);
                c.sendFrame164(973);
                c.NpcDialogueSend = true;
        }
       
        public void playerChat(String text, String text2) { // Player talking.
                client c = null;
                c.sendFrame200(974, 595);
                c.sendFrame126(c.playerName, 975);
                c.sendFrame126(text, 976);
                c.sendFrame126(text2, 977);
                c.sendFrame185(973);
                c.sendFrame164(973);
                c.NpcDialogueSend = true;
        }

        public void npcChat(String text, int npc) { // NPC talking.
                client c = null;
                c.sendFrame200(4883, 591);
                c.sendFrame126(c.GetNpcName(npc), 4884);
                c.sendFrame126(text, 4885);
                c.sendFrame126("Click here to continue.", 4886);
                c.sendFrame75(npc, 4883);
                c.sendFrame164(4882);
                c.NpcDialogueSend = true;
        }
       
        public void npcChat(String text, String text2, int npc) { // NPC talking.
                client c = null;
                c.sendFrame200(4901, 591);
                c.sendFrame126(c.GetNpcName(npc), 4902);
                c.sendFrame126("", 4903);
                c.sendFrame126(text, 4904);
                c.sendFrame126(text2, 4905);
                c.sendFrame126("", 4906);
                c.sendFrame75(npc, 4901);
                c.sendFrame164(4900);
        }
       
        public void choice(String option1, String option2) {
                client c = null;
        c.changeText126("Select an Option", 2460);
        c.changeText126(option1, 2461);
        c.changeText126(option2, 2462);
        c.sendFrame164(2459);
        }
       
        public void nextChat(int next) {               
                if (next > 0) {
                        nextChat = next;
                        sendChat = true;
                } else if(next == -1) {
                        nextChat = next;
                }
        }
       
        public static int nextChat = -1;
        public static boolean sendChat = false;       
       
}

---

In server.java under:

Code:

---

public static PlayerHandler playerHandler = null;

---

Add:

Code:

---

public static Dialogue Dialogue = null;

---

And under:

Code:

---

playerHandler = new PlayerHandler();

---

Add:

Code:

---

Dialogue = new Dialogue();

---

Now in client.java in case 40, at the top, add:

Code:

---

        if (server.Dialogue.sendChat) {
                NpcDialogue = server.Dialogue.nextChat;
                NpcDialogueSend = false;
                server.Dialogue.sendChat = false;
        } else if (server.Dialogue.nextChat == -1) {
                server.Dialogue.sendChat = false;
                NpcDialogue = 0;
                NpcDialogueSend = false;
                RemoveAllWindows();
        }

---

Now under:

Code:

---

UpdateNPCChat();

---

Add:

Code:

---

server.Dialogue.npcChat(playerId);

---

Now if you have a clickingMost.java, (If not look in packet 185 [Case 185:]) Look for:

Code:

---

case 9157:

---

Under that add:

clickingMost or any other handler:

Code:

---

server.Dialogue.option1(c.playerId);

---

else:

Code:

---

server.Dialogue.option1(playerId);

---

Now under:

Code:

---

case 9158:

---

add:

clickingMost or any other handler:

Code:

---

server.Dialogue.option2(c.playerId);

---

else:

Code:

---

server.Dialogue.option2(playerId);

---

Now to use, in:

Code:

---

public void npcChat(int ID) {

---

Under:

Code:

---

switch (c.NpcDialogue) {

---

add your dialogue.

Example:

Code:

---

case 1:
        npcChat(line1", "line2", NpcID);
        nextChat(Next 'case', 2);
break;
               
case 2:
        npcChat("Npc Talking one line", NpcID);
        nextChat(Skip 3, 4);
break;
       
case 3:
        playerChat("Player Talking");
        nextChat(To end, -1);
break;

case 4:
        playerChat("Go Back to 3",  "Line 2 of player talking");
        nextChat(3);
break;

Thanks and please do :D

Good Job bro. Repped.

No idea if I did something wrong or what, but every time I try to talk to the npc, it just disconnects me and prints out this:

Code:

---

java.lang.NullPointerException
        at Dialogue.npcChat(Dialogue.java:92)
        at Dialogue.npcChat(Dialogue.java:12)
        at client.process(client.java:18525)
        at PlayerHandler.process(PlayerHandler.java:317)
        at process.run(process.java:23)
        at java.lang.Thread.run(Unknown Source)

---

So, any idea where's the problem? :s
