[1.7.10]GuiButton help <SOLVED>

Posted December 5, 201410 yr

hi, I'm adding a button to my furnace which has functionality to act as an activator (such as a button on and off), however as the gui is in the client side I have no way to get the server TileEntity to change it, I do not know how I can do this by client, already tried using Conteiner.detectAndSendChanges () to try to update the TileEntity on 2 sides did not have more success (it seems that only works the server to the client not the reverse).

follows my code of gui and container:

package teste;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.entity.player.InventoryPlayer;
import net.minecraft.inventory.Container;
import net.minecraft.inventory.ICrafting;
import net.minecraft.inventory.Slot;
import net.minecraft.inventory.SlotFurnace;
import net.minecraft.item.ItemStack;

public class InductionFurnaceContainer extends Container {

private InductionFurnaceTileEntity tileEntity;
public int lastBurnTime;
public int lastItemBurnTime;
public int[] lastCookTime = new int[5];

        // the flag of my button control
public int lastPowerFlag;

public InductionFurnaceContainer(InventoryPlayer ivPlayer,
		InductionFurnaceTileEntity tileEntity) {
	this.tileEntity = tileEntity;
	// cria os slots em relação do numero do slot com a sua posição na gui
	// 0-4 - stocks
	// 5-9 - place
	// 11-4 - result
	for (int i = 0; i < 5; i++) {
		addSlotToContainer(new Slot(tileEntity,
				InductionFurnaceTileEntity.INGREDIENT_STOCK[i], 42,
				25 + (18 * i)));
		addSlotToContainer(new InductionFurnaceLockedSlot(tileEntity,
				InductionFurnaceTileEntity.INGREDIENT_PLACE[i], 120,
				25 + (18 * i)));
		addSlotToContainer(new SlotFurnace(ivPlayer.player, tileEntity,
				InductionFurnaceTileEntity.RESULT[i], 198, 25 + (18 * i)));
	}
	// 15 - fuel
	addSlotToContainer(new Slot(tileEntity,
			InductionFurnaceTileEntity.FUEL_PLACE, 120, 135));
	// 16-43 Player inventory back
	// 44-52 Player inventory hand
	int i;
	for (i = 0; i < 3; ++i) {
		for (int j = 0; j < 9; ++j) {
			this.addSlotToContainer(new Slot(ivPlayer, j + (i * 9) + 9,
					48 + (18 * j), 175 + (18 * i)));
		}
	}
	for (i = 0; i < 9; ++i) {
		this.addSlotToContainer(new Slot(ivPlayer, i, 48 + (18 * i), 233));
	}
}
// ids :

		iCraftting.sendProgressBarUpdate(this, i, tileEntity.cookTime[i]);
	}
	iCraftting.sendProgressBarUpdate(this, 5, tileEntity.burnTime);
	iCraftting.sendProgressBarUpdate(this, 6,
			tileEntity.currentItemBurnTime);
	iCraftting.sendProgressBarUpdate(this, 7, tileEntity.powerFlag ? 1 : 0);
}

// public void addPowerFlagToCraftters(ICrafting iCraftting) {
// super.addCraftingToCrafters(iCraftting);

@Override

public void detectAndSendChanges() {

	super.detectAndSendChanges();

	// eu acho que se refere a cada player que tem ativo o bloco
	for (int ic = 0; ic < crafters.size(); ic++) {
		ICrafting iCraftting = (ICrafting) crafters.get(ic);

		if (b != tileEntity.powerFlag) {
			iCraftting.sendProgressBarUpdate(this, 7,
					tileEntity.powerFlag ? 1 : 0);
		}
	}

	lastCookTime = tileEntity.cookTime.clone();
	lastBurnTime = tileEntity.burnTime;

The container is only used to synchronise the client with the server. For buttons you will need a packet handler. Its very easy to set one up just follow this tutorial.

hello again, follow the tutorial that showed me and creates a code but I'm having trouble, he is returning me excpetion.

below is the code and the result of the console:

IMessage

package teste;

import io.netty.buffer.ByteBuf;
import cpw.mods.fml.common.network.ByteBufUtils;
import cpw.mods.fml.common.network.simpleimpl.IMessage;

public class InductionFurnacePowerPacket implements IMessage {

public static final String POWER_SWITCH_MSG = "0";

public String text;

public InductionFurnacePowerPacket(String text) {
	this.text = text;
}

@Override
public void fromBytes(ByteBuf buf) {
	text = ByteBufUtils.readUTF8String(buf);
}

@Override
public void toBytes(ByteBuf buf) {
	ByteBufUtils.writeUTF8String(buf, text);
}
}

IMessageHandler (its my TileEntity so i will show onMessage) :

@Override
public IMessage onMessage(InductionFurnacePowerPacket message,
		MessageContext ctx) {
	System.out.println(String.format("Received %s from %s", message.text,
			ctx.getServerHandler().playerEntity.getDisplayName()));
	if (message.text == InductionFurnacePowerPacket.POWER_SWITCH_MSG) {
		powerFlag = !powerFlag;
	}
	return null;
}

init()

networkWrapper = NetworkRegistry.INSTANCE.newSimpleChannel("myChannel");
	networkWrapper.registerMessage(InductionFurnaceTileEntity.class,
			InductionFurnacePowerPacket.class, 0, Side.SERVER);

actionPerformed (send packet):

@Override
protected void actionPerformed(GuiButton button) {
	switch (button.id) {
	case 0:
		System.out.println("clique detect");
		testemod.networkWrapper
				.sendToServer(new InductionFurnacePowerPacket(
						InductionFurnacePowerPacket.POWER_SWITCH_MSG));
	}
}

the exception

what am I doing wrong?

Your IMessage implantation needs to have a no-args constructor.

BEFORE ASKING FOR HELP READ THE EAQ!

I'll help if I can. Apologies if I do something obviously stupid.

If you don't know basic Java yet, go and follow these tutorials.

exact, before I was using TileEntity to implement iMessage, but he has a constructor with arguments, then i made following the example of the inner class and got = b.

thanks for listening

New Forum Design/Update: Issues and Suggestions

Hiho,

first of all I want to say that the new forum design looks really good.

However, there are currently two issues:

In the "Unread" section, the "Mark all as Read" feature seems to be missing - or am I just overlooking it somewhere?
Some threads don’t automatically get marked as read when you open them. So the post still shows up in "Unread," even though you’ve already viewed it.
Example Thread: https://forums.minecraftforge.net/topic/159415-cannot-find-client-log-entries/

Then I have a smaller suggestion, referring to the Text Editor:

It is possible to move out the "Inline Code"-Feature from the "More Formatting Options" and add it directly to the Text Editor Tool Bar?
Same for "Quote"-Feature inside the Create Section

These two features are used quite often (at least by me) - as far as I remember, they were also available in the old forum design.

Trying to boot MC Eternal 2 Server, works on linux not on Windows 11: Jvm args error

That fixed it! it's still being weird and not actually printing anything to CMD but the logs look fine and eventually the gui generated looking normal. Thanks for your help I've done that on linux before but windows servers have always just worked with one click for some reason for me

Make sure you are using Java 17 JDK

In the start script, replace the word "java" with the java 17 path (javaw.exe) and put it into quotation marks
