im so so so sorry to bother this section so much but it seems that i cant find anything online....

 

in 1.9.4 whatever i try with sending chat to the player seems to just not send the chat and just dump

NullPointerException

errors

i looked all over the internet and a bit in the code but i didnt find anything....

 

 

anyone?

For example: if a player has joined the game and you want it to say something, do this:

@SubscribeEvent
public void onPlayerJoin(PlayerLoggedInEvent event) {
	EntityPlayer player = event.player;
	player.addChatMessage(new TextComponentString("Welcome!"));
}

and if you want to get the playername in the message:

@SubscribeEvent
public void onPlayerJoin(PlayerLoggedInEvent event) {
	EntityPlayer player = event.player;
	player.addChatMessage(new TextComponentString("Welcome, " + player.getDisplayNameString()));
}

 

For example: if a player has joined the game and you want it to say something, do this:

@SubscribeEvent
public void onPlayerJoin(PlayerLoggedInEvent event) {
	EntityPlayer player = event.player;
	player.addChatMessage(new TextComponentString("Welcome!"));
}

and if you want to get the playername in the message:

@SubscribeEvent
public void onPlayerJoin(PlayerLoggedInEvent event) {
	EntityPlayer player = event.player;
	player.addChatMessage(new TextComponentString("Welcome, " + player.getDisplayNameString()));
}

 

the problem here is that im doing it while ingame and i want it to display only for the player using

Minecraft.getMinecraft().thePlayer

and when i try

addChatMessage(new TextComponentString("Welcome, " + player.getDisplayNameString()));

it dumps a bunch of errors

When do you want it to 'say' something in chat?

When do you want it to 'say' something in chat?

once after my

Delay

passed and the delay is processed by client tick and system millis

So if you join a game, once per (for example) 10 seconds?

So if you join a game, once per (for example) 10 seconds?

i get a spesific chat message and make it reset the delayobject and then in the client tick i make it check if the delay has passed and if it did then chat to

Minecraft.getMinecraft().thePlayer

and stop the delay

ok lets say this is my class:

public class RingsChatHandler {

    public static Delay Timeout = new Delay(60);


    public static void Message(String originalMessage){
        if (RingsHUD.Enabled) {
            if ((originalMessage.contains("8|")) && (originalMessage.contains("9Elytra Racing "))) {
                if (originalMessage.contains("cFailed to reach next ring!")) { // failed
                    RingsHUD.CheckpointTextColor = "COLOR_RED";
                    Timeout.Reset();
                    RingsHUD.ActualCheckPointString = S.F+"lFailed";
                }
                if (originalMessage.contains("eYou have passed ring #")) { //ring passed
                    RingsHUD.CheckpointTextColor = "COLOR_ORANGE";

                    ///-Get Ring Cur/Max
                    int startat = 0;
                    int endat = 0;
                    RingsHUD.ActualCheckPointString = S.F+"l";
                    for (int i = 1; i < originalMessage.length(); i++) {
                        if(originalMessage.charAt(i) == '(')
                            startat = i + 1;
                        if(originalMessage.charAt(i) == ')')
                            endat = i - 1;
                    }
                    for(int j = startat; j <= endat; j++){
                        RingsHUD.ActualCheckPointString = RingsHUD.ActualCheckPointString + originalMessage.charAt(j);
                    }
                }
                if (originalMessage.contains("aYou have completed the map (")) { /// finished the map
                    RingsHUD.CheckpointTextColor = "COLOR_LGREEN";
                    RingsHUD.ActualCheckPointString = S.F+"lFinished!";
                    Timeout.Reset();
                }
            }
        }
    }
}

and i have it checking for chat messages and the gametick class:

public class Timeout{
    @SubscribeEvent
    public void onClientTick(TickEvent.ClientTickEvent event) {
        if(RingsChatHandler.Timeout.Passed()){
            S.cP("this is just a test");
            RingsChatHandler.Timeout.StopForever // this is just temporery i will fix it after i get chat working
        }
    }
}

annd this is my S.class i made it for short commands..

public class S{ //this class contains short codes to mass use
    public static Character F = ' '; // this is the section sign, it is set after the you join the server
    public static void lg(String text){System.out.println(text);} // log to console
    public static void cP(String text){Reference.PLAYER.addChatMessage(new TextComponentString(text));} // chat to player
}

and i have this in my Reference class:

    public static final EntityPlayer PLAYER = Minecraft.getMinecraft().thePlayer;

 

now when i try to use

S.cP("just some text")

it does not crash but its not working and its producing:

and please ignore my horrible code...

This line:

public static final EntityPlayer PLAYER = Minecraft.getMinecraft().thePlayer;

Before the player has started a game or joined a server,

PLAYER

is guaranteed to be null.

so i need it to not be final and set it when the event happend?

 

this didnt happen..

i didnt think that the player could be nothing...
