Now, pressing the keybind causes lag Going to options crashed the client

It doesn't let me put it there here is the crash https://pastebin.com/1xx32Fmg

Now the server starts, but when the keybind is pressed, the client crashes

what do you mean by seperate it?

private void doClientStuff(final FMLClientSetupEvent event) { KeyBinds.registerKeyBindings(); } this is my main @Mod.EventBusSubscriber(modid = CrudeTechMod.MOD_ID, bus = Bus.FORGE) public class KeyBinds { static KeyBinding[] keyBindings = new KeyBinding[1]; public static final KeyBinding keyExplosiveJump = new KeyBinding("Explosive Jump", GLFW.GLFW_KEY_Y, "Crude Tech"); static Boolean keyExplosiveJumpPress = false; public static void registerKeyBindings() { for(int i=0; i<keyBindings.length; i++) { ClientRegistry.registerKeyBinding(keyBindings[i]); } } private static final String PROTOCOL_VERSION = "1"; public static final SimpleChannel INSTANCE = NetworkRegistry.newSimpleChannel( new ResourceLocation(CrudeTechMod.MOD_ID, "explosivejump"), () -> PROTOCOL_VERSION, PROTOCOL_VERSION::equals, PROTOCOL_VERSION::equals ); static int i=0; @SubscribeEvent public static void onInput (InputEvent.KeyInputEvent event) { if(event.getKey()==keyExplosiveJump.getKey().getKeyCode() && !keyExplosiveJumpPress && Minecraft.getInstance().player.getItemStackFromSlot(EquipmentSlotType.FEET).getItem()==ModItems.KABOOTS.get()) { CrudeTechMod.log("pressed"); INSTANCE.registerMessage(i++, key.class, key::encode, key::decode, key::handle); INSTANCE.sendToServer(new key(0)); keyExplosiveJumpPress=true; } } @SubscribeEvent public static void onTick (ClientTickEvent event) { if(keyExplosiveJumpPress && !keyExplosiveJump.isKeyDown()) { keyExplosiveJumpPress=false; } } } This is KeyBinds.java Should I move INSTANCE.registerMessage(i++, key.class, key::encode, key::decode, key::handle); to registerKeyBindings?

It works now private static final String PROTOCOL_VERSION = "1"; public static final SimpleChannel INSTANCE = NetworkRegistry.newSimpleChannel( new ResourceLocation(CrudeTechMod.MOD_ID, "explosivejump"), () -> PROTOCOL_VERSION, PROTOCOL_VERSION::equals, PROTOCOL_VERSION::equals ); static int i=0; @SubscribeEvent public static void onInput (InputEvent.KeyInputEvent event) { if(event.getKey()==keyExplosiveJump.getKey().getKeyCode() && !keyExplosiveJumpPress && Minecraft.getInstance().player.getItemStackFromSlot(EquipmentSlotType.FEET).getItem()==ModItems.KABOOTS.get()) { CrudeTechMod.log("pressed"); INSTANCE.registerMessage(i++, key.class, key::encode, key::decode, key::handle); INSTANCE.sendToServer(new key(0)); keyExplosiveJumpPress=true; } }

How do I do that?

Make a class that extends ArmorItem override onArmorItem to give the wearer effects Make your armor using that class instead of ArmorItem If it's a vanilla armor Subscribe to PlayerTickEvent on the server side check their armor, and give effects

Your code has so many indents. Also, you're not using deferred registries. public static final DeferredRegister<Item> ITEMS = new DeferredRegister<>(ForgeRegistries.ITEMS, ALilSalty.MOD_ID); This is a registry event

Thank you Everything works now

oh nvm that is just an issue in my renderer [me.jo.be.BedrockThings/]: ClientPlayerEntity['Dev'/1, l='MpServer', x=215.40, y=3.94, z=339.80] != ClientPlayerEntity['Dev'/1, l='MpServer', x=215.40, y=3.94, z=339.80]

It stopped crashing! but the projectile is still invisible

should I use world.isRemote() instead? I've just been copying vanilla
