Hello, I want to change enchantment color of vanilla sword depends on enchantments level and types. I found glint.png in Minecraft files and it's gray so probably color of enchantment is somewhere in the code. I think that I need my own item renderer, but I don't know how to make it and attach it to the vanilla sword. I've tried to extend RenderItem but most of its methods are private, so I can't override them.

I've changed the player to null and it works. Problem solved. Thank you guys for helping.

Ok, I made a client packet which is playing sound. Everything works. Thank you.

Hello, I've made a custom sound and test event to play it, but it won't work. When I break block nothing happens. What is wrong with my code? sounds.json { "item.soulshot.activated": { "category": "player", "subtitle": "item.soulshot.activated", "sounds": [ { "name": "lineagecraft:item/soulshot/activated", "stream": true } ] } } Sound handler public class SoundHandler { private static int size = 0; public static SoundEvent SOULSHOT_ACTIVATED; public static void init(){ size = SoundEvent.REGISTRY.getKeys().size(); SOULSHOT_ACTIVATED = register("item.soulshot.activated"); } public static SoundEvent register(String name){ ResourceLocation location = new ResourceLocation(Reference.MOD_ID, name); SoundEvent e = new SoundEvent(location); SoundEvent.REGISTRY.register(size, location, e); size++; return e; } } Event with playSound @SubscribeEvent public void onTest(BreakEvent event){ event.getPlayer().sendMessage(new TextComponentString("Block break")); event.getWorld().playSound(event.getPlayer(), event.getPlayer().getPosition(), SoundHandler.SOULSHOT_ACTIVATED, SoundCategory.PLAYERS, 1.0F, 1.0F); } init @EventHandler public void init(FMLInitializationEvent event){ SoundHandler.init(); }

Yes I know java, but I'm still learning. I made array of strings, and it works fine. Sorry for that noob question.

Thank you for reply. How can I change existing string?

Hello guys. I have a problem. Drawing string in gui works only inside drawGuiContainerForegroundLayer method. @Override protected void drawGuiContainerForegroundLayer(int mouseX, int mouseY) { this.fontRendererObj.drawString("test", 8, 50, 4210752); //works fine } When I'm using this here @Override protected void actionPerformed(GuiButton button) throws IOException { this.fontRendererObj.drawString("test", 8, 50, 4210752); //not working } it shows nothing. How can I dynamic draw strings in gui?

Hi. I want to make item similar to barrel from other mods, but only for few items. I want to fill it via crafting. For example 20x cobblestone + myItem = myItem with data about storage 20x cobblestone. But i don't know how to do that kind of crafting. Thanks you for help in advance.

I didn't post crash log, cuz game exacly freeze not crash. But now everything works, problem solved. Thank you guys.

Thank you. I know how to get player and playerInventory, but how can I get item inventory from packet? Edit: I made this, but minecraft is crashing when I press the button.

Hello guys. Sorry for my english and thank you in advance for help. I've made item with gui that should add sharpness enchantment to the diamond sword. Everything works fine but when i pick up sword it lost enchantments. Also player should lost 5 experience lvls, but it's not working. There's video that shows the problem.
