[1.10.2] [ClientMod] What is FML's safe way of injecting elements to a gui?

From what I understand, FML is supposed to make sure all mods can work together by adding its own ways of adding stuff.....

I want to add a button element to the "esc menu" of the game that I can direct to my own gui....

The only way I know of to do that is by listening to gui changes and checking for that gui, then overriding it with my own clone of it...

I looked a bit online with no luck of finding any answer so I came to the forum as usall...

Instead of Overriding just add a button like you would with your own gui, not sure if reflection is necessary though.

VANILLA MINECRAFT CLASSES ARE THE BEST RESOURCES WHEN MODDING

I will be posting 1.15.2 modding tutorials on this channel. If you want to be notified of it do the normal YouTube stuff like subscribing, ect.

Giant there something that prevents overlapping?

 

If I get you correctly (stupid autocorrect? :D), you'll need to calculate the button position yourself (to put your button under other buttons). Or you could just place your button in the corner.

 

By the way, you'll probably need to subscribe to ActionPerformedEvent also to add a callback when the button was clicked in GuiIngameMenu.

Yes.. stupid auto correct...

I guess ill have to just place a button in hopes that no one uses its place..

But, is there a change you can show me an example on how you would register/use/imply the event on such button in the esc menu?

Im not on pc do i cant test stuff...

mod file :

//preinit

new AddButtonToGuiEvent(); //custom class

 

public class AddButtonToGuiEvent{

 

public AddButtonToGuiEvent(){

MinecraftForge.EVENT_BUS.register(this);

}

 

@SubscribeEvent

public void onGuiEvent(TheEventIwantToUse event){

event.getbuttonlist.add(new guibutton(stuff,foo,bar,things);

}

 

}

 

 

very rudamentary implementation. for example only.

/* In your proxy on pre initialization (FMLPreInitializationEvent) or 
* initialization (FMLInitializationEvent): */

GuiEventHandler handler = new GuiEventHandler();
MinecraftForge.EVENT_BUS.register(handler);

/* The class itself */
public class GuiEventHandler
{
    @SubscribeEvent
    public void onGuiInit(InitGuiEvent.Pre event)
    {
        if (event.getGui() instanceof GuiIngameMenu)
        {
            /* Add button to top-left corner of the screen */
            event.getButtonList().add(new GuiButton(42, 10, 10, ...));
        }
    }
    
    @SubscribeEvent
    public void onGuiActionPerformed(ActionPerformedEvent event)
    {
        if (event.getGui() instanceof GuiIngameMenu && event.getButton().id == 42)
        {
            /* Do something... */
        }
    }
}

 

My code doesn't really differ from SenpaiSuburaki's code, but there are few important features added/changed.

 

  • Check for GuiIngameMenu – it is really important since without this check you may accidentally add your button to every GUI in the game.
  • ActionPerformed event listener was added – where the comment "Do something..." you should write your custom code that should happen after your added button was clicked (i.e. open other GUI, Minecraft.getMinecraft().displayGuiScreen(...)).
  • Moved registration of event handler outside of the class. Why? Because it's bad, in my opinion, since it will hardcode (add hard dependency, coupling) MinecraftForge.EVENT_BUS to this class.

 

The code provided above is untested, but I believe it should work with minor adjustments (i.e. add imports and change some parameters to desired values).

    • Made a modpack (Well Rounded Blockheads, in case the modlist on curseforge helps) and server to host it, worked fine until last night. The issue that pops up after some days being up/working is when you leave a world (singleplayer) or shutdown a server, the process hangs and jumps to 8.5gb ram used, eats up CPU usage (50-60% in taskman on a 3800x) and just sits there. If done on a single player world, the game doesnt fully crash, (e.g. if you alt+f4 buttons like save and quit, options stay in the window, are still clickable but they do nothing) Saving seems to still happen, as location/inventory updates if I restart server or client and play the world again.   If I start the currently afflicted server but dont login the server closes properly, its only once I log back in the problem occurs. Its a priv server and I dont have anyone else to test atm so Idk if its a prob with my player or players/area in general. Only recent changes in game are the additions of a pnuematicraft pressure chamber, an enchanting table, and bookshelves from builders crafts and additions.... I've been trying to get help on this all day, so ANY assistance goes a long way, even if its a way to debug this myself >~< Debug/Latest logs
    • Thanks warjort. I was afraid, that this is because they are entities. Now I know where to dig. But what about water, for example? I have checked via debug code, that there is no entity there (appropriate method return null). What is wrong with liquids?
    • After attempting to run it again today, the debug.log is still showing the same file, so it definitely isn't updating.
