[1.7.10] Detecting if a player is typing in the chat

Recommended Posts

Hello there,

 

I encounter some difficulties making my first mod.

 

Goals :

- detecting if a player is typing in the chat (not detecting if the chat is open, but when the player starts writing).

- detecting if the first character the player wrote is a "!".

 

I tried this :

@SubscribeEvent
public void onEvent(RenderTickEvent event)
{
    if (Minecraft.getMinecraft().ingameGUI.getChatGUI().getChatOpen())
    {
        if(keyBindTest.isPressed())
        {
            System.out.println("debug");
        }
    }
        
}

In this case, detecting if the chat is open works, but detecting the keypress doesn't.

 

Another try :

@SubscribeEvent
public void onEvent(KeyInputEvent event)
{
    if(keyBindTest.isPressed() && Minecraft.getMinecraft().ingameGUI.getChatGUI().getChatOpen())
    {
        System.out.println("debug");
    }
}

In this case, the keypress isn't detected either. Without "Minecraft.getMinecraft().ingameGUI.getChatGUI().getChatOpen()", detecting the keypress works, but only outside the chat.

 

Do you have any idea ?

I think this is difficult.  The key events seem to be suppressed when some GUIs are opened.  As you found out, it is easy to detect that chat is open, and you can also process the chat input before it is actually sent to server, but not sure you can get it key by key.

 

What are you trying to achieve exactly?

Thank you for your answer.

I'm trying to display an image above the head of players who are typing in the chat. Players must be able to read the chat history without displaying this image, that's why I need to check if the player is typing or not.

 

I've seen this feature on a server, so I guess it's realizable.

You may want to consider testing the "raw" keyboard input, either within the Keyboard class or even with just basic Java.  The KeyInputEvent seems to be filtered a bit.

 

So maybe try the KeyBoard.isKeyDown() method -- you'd have to cycle through the letter keys or something and if any are down within certain timeframe you could assume that the user is "typing".

I have been searching for hours when I found this : https://github.com/coolAlias/Tutorial-1.7.2/blob/master/src/main/java/tutorial/client/gui/GuiCustomPlayerInventory.java

and this : http://www.minecraftforge.net/forum/index.php?topic=17647.0 , from the same guy.

 

This guy seems to close his GUI without "KeyInputEvent". However, I don't really understand how it works... do you think it could be a solution ?

It seems I need to override this (in net.minecraft.client.gui.GuiScreen) :

 

/**
     * Fired when a key is typed. This is the equivalent of KeyListener.keyTyped(KeyEvent e).
     */
    protected void keyTyped(char p_73869_1_, int p_73869_2_)
    {
        if (p_73869_2_ == 1)
        {
            this.mc.displayGuiScreen((GuiScreen)null);
            this.mc.setIngameFocus();
        }
    }

 

So, I created this class :

import net.minecraft.client.gui.GuiScreen;

public class GuiScreenOverride extends GuiScreen {

@Override
public void keyTyped(char c, int i){
	System.out.println("debug");
}
}

 

But I don't know where I need to use it to make it works...

You're best bet is to just hook keyevent and test for two key sequence <chat-key>! or what have you. That would require a simple state machine. It would listen to return as well to know the chat was terminated.
