I would like to use keybinding to open my gui. I could see my KeyBinding in the setting but when I press P it does not pop the GUI out. This is what I've done: Main Class: @EventHandler public void postInit(FMLPostInitializationEvent event) { KeyBindingRegistry.registerKeyBinding(new KeyBindingHandler()); KeyBindingHandler class: public class KeyBindingHandler extends KeyHandler { public KeyBindingHandler() { super(arrayOfKeys, areRepeating); } public static KeyBinding test = new KeyBinding("SAO", Keyboard.KEY_P); public static KeyBinding[] arrayOfKeys = new KeyBinding[] {test}; public static boolean[] areRepeating = new boolean[] {false}; public Minecraft mc; @Override public String getLabel() { return "Test KeyBinding"; } @Override public void keyDown(EnumSet<TickType> types, KeyBinding kb, boolean tickEnd, boolean isRepeat) { mc.displayGuiScreen(new YourGui()); } @Override public void keyUp(EnumSet<TickType> types, KeyBinding kb, boolean tickEnd) { } @Override public EnumSet<TickType> ticks() { return null; } } My Test GUI class: public class YourGui extends GuiScreen{ private GuiScreen parentScreen; public void initGui() { } public void drawScreen(int par1, int par2, float par3) { drawDefaultBackground(); super.drawScreen(par1,par2,par3); } } Please help guys

How can I make a custom sword unbreakable? If can't how could I set the durability of the sword?

Even the level is 0 it still heals my bar full. Because I got a 1 second instant heal effect. And it heals me 10 hearts in just a second. But if I set the time to 0 second. It won't heal me. What should I do?

Hi, I am working on a food that will heal the player 2 hearts after ate. I've used the method setPotionEffect, I've tested it with moveSpeed and it worked. But the Instant heal seems not working Here's the code this.setPotionEffect(Potion.heal.id, 1, 4, 100); When I test the food. It didn't heal me 2 hearts but heal my bar full. How should I modify the method so that it will only heal 2 hearts? Sorry for my bad English. But please help

the problem?

I have used the method onBlockActivated so that if player rightclicked the block with an arrow, it turns the arrow into an diamond But what I wanted to do is arrow, iron ingot and gold. This three item also can be changed into a diamond What should I do? I had tried if(par5EntityPlayer.getCurrentEquippedItem().itemID != (Item.arrow.itemID && Item.ingotIron.itemID)) But not working, anyhelp? Here's my code @Override public boolean onBlockActivated(World par1World, int par2, int par3, int par4, EntityPlayer par5EntityPlayer, int par6, float par7, float par8, float par9){ if(!par1World.isRemote){ if (par5EntityPlayer.getCurrentEquippedItem() == null)//prevents npe exceptions (NullPointerException) return false; if(par5EntityPlayer.getCurrentEquippedItem().itemID != Item.arrow.itemID) return false; par5EntityPlayer.inventory.mainInventory[par5EntityPlayer.inventory.currentItem] = new ItemStack(Item.diamond.itemID, 1, 0); par1World.setBlockToAir(par2, par3, par4); } return false;

I have tried to use it, but still get error... any help? public boolean onBlockActivated(World par1World, int par2, int par3, int par4, EntityPlayer par5EntityPlayer, int par6, float par7, float par8, float par9) { if World.isRemote == false; ItemStack dirt = new ItemStack(Block.dirt); EntityItem test = new EntityItem(par1World, par2, par3, par4, dirt); World.spawnEntityInWorld(test) end if

Can you give me an example code? Because im new in modding
