But it doesn't seem to work in my project.

I've made an event for my custom enchantment, and it need to change the player's speed. I tried to use PlayerEntity#addPotionEffect but it did bad with the player who has speed effect. How can I just modify the speed of the player?

Ok. I've check the tutorial but It went wrong in my project public class ModDimensions extends ModDimension{ } It says there are no class ModDimension

I want to make a simple custom dimension but I don't know how to do it. I tried to refer to the mod Twilight Forest, but the dimension is too complex for me to read. Can anybody give me a simple example or a tutorial for making custom Dimensions? Thanks.

Ok. I got it. Thanks and I'm almost done.😀

The event file: @SubscribeEvent public static void onWithVoidSpeedEnchantment(LivingEquipmentChangeEvent event, ItemStack itemStack, LivingDamageEvent event2) { LivingEntity player = event.getEntityLiving(); EquipmentSlotType slot = event.getSlot(); if (player instanceof PlayerEntity) { if (EnchantmentHelper.getMaxEnchantmentLevel(RegistryHandler.VOID_SPEED.get(), player) > 0) { player.addPotionEffect(new EffectInstance(Effects.SPEED, 1, 3)); } } } And I don't now how to do damage to player. The register file: public static final DeferredRegister<Enchantment> ENCHANTMENTS = DeferredRegister.create(ForgeRegistries.ENCHANTMENTS, Technology.MOD_ID); public static final RegistryObject<Enchantment> VOID_SPEED = ENCHANTMENTS.register("void_speed", VoidSpeedEnchantment::new); The enchantment file: public class VoidSpeedEnchantment extends Enchantment { public VoidSpeedEnchantment() { super(Rarity.VERY_RARE, EnchantmentType.ARMOR_FEET, new EquipmentSlotType[]{EquipmentSlotType.FEET}); } @Override public int getMaxLevel() { return 4; } @Override public int getMinEnchantability(int enchantmentLevel) { return enchantmentLevel * 20; } @Override public int getMaxEnchantability(int enchantmentLevel) { return this.getMinEnchantability(enchantmentLevel) + 15; } @Override public boolean isAllowedOnBooks() { return true; } @Override public boolean canVillagerTrade() { return false; } @Override public boolean isTreasureEnchantment() { return true; } }

And how can I check the enchantment? I used EnchantmentHelper#getMaxEnchantmentLevel but failed

I'm really new in forge modding, so how can I check if the entity is a player? if (player instanceof PlayerEntity){ } like this?

I have added an enchantment to my mod and it has some problem when running the mod. The feature of the enchantment should be: When the feet slot have this enchantment, the player get a speed 3 effect The player will hurt 1/40 of the probability for every 20 blocks movement The register file: public static final DeferredRegister<Enchantment> ENCHANTMENTS = DeferredRegister.create(ForgeRegistries.ENCHANTMENTS, Technology.MOD_ID); private static final EquipmentSlotType[] LEGS = new EquipmentSlotType[]{EquipmentSlotType.FEET}; public static final RegistryObject<Enchantment> VOID_SPEED = ENCHANTMENTS.register("void_speed", () -> new VoidSpeedEnchantment(Enchantment.Rarity.VERY_RARE, EnchantmentType.ARMOR_FEET, LEGS)); The enchantment file: public class VoidSpeedEnchantment extends Enchantment { public VoidSpeedEnchantment(Rarity rarity, EnchantmentType type, EquipmentSlotType[] slots) { super(rarity, EnchantmentType.ARMOR_FEET, slots); } @Override public int getMaxLevel() { return 4; } @Override public int getMinEnchantability(int enchantmentLevel) { return enchantmentLevel * 20; } @Override public int getMaxEnchantability(int enchantmentLevel) { return this.getMinEnchantability(enchantmentLevel) + 15; } @Override public boolean isAllowedOnBooks() { return true; } @Override public boolean canVillagerTrade() { return false; } @Override public boolean isTreasureEnchantment() { return true; } } The event file: @Mod.EventBusSubscriber(modid = Technology.MOD_ID, bus = Mod.EventBusSubscriber.Bus.FORGE, value = Dist.CLIENT) public class ModClientEvents { @SubscribeEvent public static void onFeetWithVoidSpeedEnchantment(PlayerEvent event){ PlayerEntity player = event.getPlayer(); World world = event.getPlayer().getEntityWorld(); double move = event.getPlayer().getDistance(player); if (EnchantmentHelper.getMaxEnchantmentLevel(RegistryHandler.VOID_SPEED.get(), player) > 0){ // Problem shows on this line when debugging player.addPotionEffect(new EffectInstance(Effects.SPEED, 5, 3)); if (move >= 20){ move = 0; Random random = new Random(); int d1 = random.nextInt(40); if (d1 == 1){ d1 = 0; player.addPotionEffect(new EffectInstance(Effects.INSTANT_DAMAGE)); player.sendStatusMessage(new StringTextComponent(TextFormatting.RED + "Hurt by the void"), true); } } } } }

I want to make a RPG in my mod, but I don't know how to make that.
