[clientside][1.9.4] sending chat to player

[SHsuperCM]

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....

 

 

[SHsuperCM]

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()));
}

@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?

[SHsuperCM]

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

[Egietje]

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

[SHsuperCM]

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:

java.lang.NullPointerException: Unexpected error

and please ignore my horrible code...

[Draco18s]

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?

 

[SHsuperCM]

[SHsuperCM]
