[1.12] Properly creating a custom sign GUI (Without block)

[Stenbergcsgo]

Hello Minecraft Forge, I'm trying to create a GUI which does the following:

    - Player rightclicks with custom item

    - GUI similar to the sign GUI appears, where the player can input a string, which is  then stored (Client side only)

    - Clicking done closes the GUI

 

So I've tried creating this, but ran into some issues. The GUI doesn't load at all.

 

signInputGui:

package com.mta.utzonmod.client.gui;

import java.io.IOException;

import org.lwjgl.input.Keyboard;

import net.minecraft.client.gui.GuiButton;
import net.minecraft.client.gui.GuiScreen;
import net.minecraft.client.renderer.GlStateManager;
import net.minecraft.client.resources.I18n;
import net.minecraft.util.ChatAllowedCharacters;
import net.minecraft.util.text.ITextComponent;
import net.minecraft.util.text.TextComponentString;
import net.minecraftforge.fml.relauncher.Side;
import net.minecraftforge.fml.relauncher.SideOnly;

@SideOnly(Side.CLIENT)
public class signInputGui extends GuiScreen {
	
	private GuiButton doneBtn;
	
	private int updateCounter;
	
	private int editLine;
	
	public String playerInput;
	
	public void initGui() {
		this.buttonList.clear();
		Keyboard.enableRepeatEvents(true);
		this.doneBtn = this.addButton(new GuiButton(0, this.width / 2 - 100, this.height / 4 + 120, I18n.format("gui.done")));	
	}
	
	public void onGuiClosed() {
		Keyboard.enableRepeatEvents(false);
	}
	
	public void updateScreen() {
		++this.updateCounter;
	}
	
	protected void actionPerformed(GuiButton button) throws IOException {
		if(button.enabled) {
			if(button.id == 0) {
				this.mc.displayGuiScreen((GuiScreen)null);
			}
		}
	}
	
	public final ITextComponent[] signText = new ITextComponent[] {new TextComponentString(""), new TextComponentString(""), new TextComponentString(""), new TextComponentString("")};
	
	protected void keyTyped(char typedChar, int keyCode) throws IOException {
		if(keyCode == 200) {
			this.editLine = this.editLine - 1 & 3;
		}
		
		if (keyCode == 208 || keyCode == 28 || keyCode == 156) {
			this.editLine = this.editLine + 1 & 3;
		}
		
		for (int i = 0; i < 4; ++i)
        {
            playerInput = ITextComponent.Serializer.componentToJson(this.signText[i]);
        }
		
		if (keyCode == 14 && !playerInput.isEmpty()) {
			playerInput = playerInput.substring(0, playerInput.length() - 1);
		}
		
		if (ChatAllowedCharacters.isAllowedCharacter(typedChar) && this.fontRenderer.getStringWidth(playerInput + typedChar) <= 90) {
			playerInput = playerInput + typedChar;
		}
		
		if (keyCode == 1) {
			this.actionPerformed(this.doneBtn);
		}	
	}
	
	public void drawScreen(int mouseX, int mouseY, float partialTicks) {
		this.drawDefaultBackground();
		this.drawCenteredString(this.fontRenderer, I18n.format("sign.edit"),this.width / 2, 40, 16777215);
		GlStateManager.color(1.0F,  1.0F,  1.0F, 1.0F);
		GlStateManager.pushMatrix();
		GlStateManager.translate((float)(this.width / 2), 0.0F, 50.0F);
		
        GlStateManager.scale(-93.75F, -93.75F, -93.75F);
        GlStateManager.rotate(180.0F, 0.0F, 1.0F, 0.0F);
		
		GlStateManager.popMatrix();
		super.drawScreen(mouseX, mouseY, partialTicks);
	}
}

 

SchematicSign:

package com.mta.utzonmod.items;

import com.mta.utzonmod.client.gui.signInputGui;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.ItemStack;
import net.minecraft.util.ActionResult;
import net.minecraft.util.EnumHand;
import net.minecraft.util.text.ITextComponent;
import net.minecraft.util.text.TextComponentString;
import net.minecraft.world.World;

public class SchematicSign extends ItemBase {
	
	public SchematicSign(String name) {
		super(name);
	}
	
	@Override
	public ActionResult<ItemStack> onItemRightClick(World worldIn, EntityPlayer player, EnumHand handIn) {
		ITextComponent message = new TextComponentString("Hello");
		player.sendMessage(message);
		//player.openGui(Main.instance, 0, worldIn, 1, 1, 1);
		signInputGui inputGui = new signInputGui();
		inputGui.initGui();
		return super.onItemRightClick(worldIn, player, handIn);
	}
}

 

ItemBase:

package com.mta.utzonmod.items;

import com.mta.utzonmod.Main;
import com.mta.utzonmod.init.ModItems;
import com.mta.utzonmod.util.IHasModel;

import net.minecraft.item.Item;
import net.minecraft.nbt.NBTTagCompound;

public class ItemBase extends Item implements IHasModel{

	public ItemBase(String name) {
		setUnlocalizedName(name);
		setRegistryName(name);
		setCreativeTab(Main.utzontab);
		
		ModItems.ITEMS.add(this);
	}
	
	@Override
	public void registerModels() {

		Main.proxy.registerItemRenderer(this, 0, "inventory");
		
	}	
}

 

So instead of messing too much around, I'd hope some of you guys might be able to chip in where I went right and where I went wrong. As mentioned the GUI doesn't even appear at the moment, which I assume is related to the "drawScreen()" not getting called.

• That's not how you open a GuiScreen. Never call initGui yourself. To open a screen, call Minecraft::displayGuiScreen.
• You cannot access client-only classes (such as your GuiScreen) from common code (your item). You must use your @SidedProxy.
• You must perform a check for the logical side in onItemRightClick.

So would I modify my ClientProxy to?:

package com.mta.utzonmod.proxy;

import com.mta.utzonmod.client.gui.signInputGui;

import net.minecraft.client.Minecraft;
import net.minecraft.client.renderer.block.model.ModelResourceLocation;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.world.World;
import net.minecraftforge.client.model.ModelLoader;
import net.minecraftforge.fml.common.network.IGuiHandler;

public class ClientProxy extends CommonProxy {
	
	public void registerItemRenderer(Item item, int meta, String id) {
		ModelLoader.setCustomModelResourceLocation(item, meta, new ModelResourceLocation(item.getRegistryName(), id));
	}
	
	public void init() {
		Minecraft mc = Minecraft.getMinecraft();
		mc.displayGuiScreen(new signInputGui());
	}
}

 

And also added the check to my item:

package com.mta.utzonmod.items;


import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.ItemStack;
import net.minecraft.util.ActionResult;
import net.minecraft.util.EnumHand;
import net.minecraft.util.text.ITextComponent;
import net.minecraft.util.text.TextComponentString;
import net.minecraft.world.World;

public class SchematicSign extends ItemBase {
	
	public SchematicSign(String name) {
		super(name);
	}
	
	@Override
	public ActionResult<ItemStack> onItemRightClick(World worldIn, EntityPlayer player, EnumHand handIn) {
		if(!worldIn.isRemote) {
			ITextComponent message = new TextComponentString("Hello");
			player.sendMessage(message);
			//player.openGui(Main.instance, 0, worldIn, 1, 1, 1);
			return super.onItemRightClick(worldIn, player, handIn);
		} else {
			return super.onItemRightClick(worldIn, player, handIn);
		}
		
	}
}

• You are now not opening the GUI at all from your item.
• You probably want to return a different result than EnumActionResult.PASS.

Just a really stupid question, so how should i properly open it from my item?

Move

Minecraft mc = Minecraft.getMinecraft();
mc.displayGuiScreen(new signInputGui());

 

to the item class?

Do you even understand how @SidedProxy works? You now made a method in your proxy, but you don't call it from anywhere. What do you think this does? Exactly: nothing.

Yea my bad guess I'm starting to oversee some stuff after messing around with it for so long. Called the init from my item, and it works now. Thanks =)
