Hi,

I have a problem with GuiButton.

First the code:

if(button.id == 2) {
	if(world.isRemote) {
		Minecraft.getMinecraft().player.sendChatMessage("/give @p " + Reference.MOD_ID + ":mystical_ingot 1");
	}
	Minecraft.getMinecraft().getSoundHandler().playSound(PositionedSoundRecord.getMasterRecord(SoundEvents.UI_BUTTON_CLICK, 1.0F));
}

The code works very well, but instead of one ingot, i receive many ingots.

So I tried to send a chat message without a command but it appears many times instead of one.

 

Some fixes?

Try with:

if(button.id == 2 && button.id.isPressed()) {
	if(world.isRemote) {
		Minecraft.getMinecraft().player.sendChatMessage("/give @p " + Reference.MOD_ID + ":mystical_ingot 1");
	}
	Minecraft.getMinecraft().getSoundHandler().playSound(PositionedSoundRecord.getMasterRecord(SoundEvents.UI_BUTTON_CLICK, 1.0F));
}

 

Maybe this should fix it

button.id.isPressed() doesn't exists.

A little info I didn't remember: this if statement is in the actionPerformed method of a GUI.

• Checking World#isRemote inside a GuiScreen is pointless and shows a fundamental misunderstanding of how client & server work in Minecraft.
• Show your complete GuiScreen.

Here it is:

package com.mistergamer.mysticalmod.gui;

public class CompactorGui extends GuiContainer{

	public static final int WIDTH = 176;
    public static final int HEIGHT = 166;
    public GuiButton button1;
    public String crafting;
    BlockPos pos = Minecraft.getMinecraft().player.getPosition();
    World world = Minecraft.getMinecraft().world;
    EntityPlayer player = Minecraft.getMinecraft().player;
    Entity entity;
    
    public static final ResourceLocation background = new ResourceLocation(Reference.MOD_ID, "textures/gui/container/compactor_gui.png");
    public static final int GUI_ID = 2;
	
	public CompactorGui(CompactorTileEntity tileEntity, CompactorContainer container) {
		super(container);
		
		xSize = WIDTH;
		ySize = HEIGHT;
	}

	@Override
	protected void drawGuiContainerBackgroundLayer(float partialTicks, int mouseX, int mouseY) {
		GL11.glColor4f(1.0f, 1.0f, 1.0f, 1.0f);
		GL11.glDisable(GL11.GL_LIGHTING);
		mc.getTextureManager().bindTexture(background);
        drawTexturedModalRect(guiLeft, guiTop, 0, 0, xSize, ySize);
        this.renderHoveredToolTip (mouseX, mouseY);
	}
	
	protected void drawGuiContainerForegroundLayer(float partialTicks, int mouseX, int mouseY) {
        this.renderHoveredToolTip(mouseX, mouseY);
	}
	
	@Override
	public boolean doesGuiPauseGame() {
		return false;
	}

	@Override
	public void drawScreen(int mouseX, int mouseY, float partialTicks) {
		this.drawDefaultBackground();
		super.drawScreen(mouseX, mouseY, partialTicks);
        this.renderHoveredToolTip(mouseX, mouseY);
        fontRenderer.drawString("Inventory", this.getGuiLeft() + 8, this.getGuiTop() + 72, 4210752);
        //Draw the Help button
        this.buttonList.add(new GuiButton(1, this.getGuiLeft() + 128, this.getGuiTop() + 62, 20, 20, "?"));
        //Draw the Mystical Ingot button and icon
        this.buttonList.add(new GuiButton(2, this.getGuiLeft() + 8, this.getGuiTop() + 8, 20, 20, ""));
        mc.getRenderItem().renderItemAndEffectIntoGUI(new ItemStack(ModItems.MYSTICAL_INGOT), this.getGuiLeft() + 10, this.getGuiTop() + 10);
        //Draw the Mystical Fuel button and icon
        this.buttonList.add(new GuiButton(3, this.getGuiLeft() + 29, this.getGuiTop() + 8, 20, 20, ""));
        mc.getRenderItem().renderItemAndEffectIntoGUI(new ItemStack(ModItems.MYSTICAL_FUEL), this.getGuiLeft() + 31, this.getGuiTop() + 10);
	}

	@Override
	protected void actionPerformed(GuiButton button) throws IOException {
		if(button.id == 1) {
			if(world.isRemote) {
				Minecraft.getMinecraft().displayGuiScreen(new CompactorHelpGui());
				Minecraft.getMinecraft().getSoundHandler().playSound(PositionedSoundRecord.getMasterRecord(SoundEvents.UI_BUTTON_CLICK, 1.0F));
			}
		}else if(button.id == 2) {
			if(world.isRemote) {
				Minecraft.getMinecraft().player.sendChatMessage("/give @p " + Reference.MOD_ID + ":mystical_ingot 1");
			}
			Minecraft.getMinecraft().getSoundHandler().playSound(PositionedSoundRecord.getMasterRecord(SoundEvents.UI_BUTTON_CLICK, 1.0F));
		}else if(button.id == 3) {
			if(world.isRemote) {
				Minecraft.getMinecraft().player.sendChatMessage("/give @p " + Reference.MOD_ID + ":mystical_fuel 1");
			}
			Minecraft.getMinecraft().getSoundHandler().playSound(PositionedSoundRecord.getMasterRecord(SoundEvents.UI_BUTTON_CLICK, 1.0F));
		}
	}
}

You are adding new buttons to the button list every frame.

So, yes, there will be multiple buttons. In fact, there will be as many buttons as frames that your screen has been visible.

So where should I draw my buttons?

Nessuno del codice che hai postato disegna i pulsanti. Li stai semplicemente creando per loro per poi essere disegnati dal codice GuiScreen .

Guarda gli esempi di vaniglia delle implementazioni di GuiScreen su come gestire i pulsanti.

I had a look at the Beacon GUI and it works now! Thank you so much!
