I am trying to make a potion called "Freeze" which will freeze a player, but it won't register, and I can't access it. Here is my code:

package com.juder.elementalswords.effect;

import net.minecraft.world.effect.MobEffect;
import net.minecraft.world.effect.MobEffectCategory;
import net.minecraft.world.entity.LivingEntity;

public class FreezeEffect extends MobEffect {
	public FreezeEffect(MobEffectCategory mobEffectCategory, int color) {
		super(mobEffectCategory, color);
	}
	
	@Override
	public void applyEffectTick(LivingEntity entity, int amplifier) {
		// TODO Auto-generated method stub
		
		if (!entity.level.isClientSide) {
			double x = entity.getX();
			double y = entity.getY();
			double z = entity.getZ();
			
			entity.teleportTo(x, y, z);
			entity.setDeltaMovement(0, 0, 0);
		}
		
		super.applyEffectTick(entity, amplifier);
	}
	
	@Override
	public boolean isDurationEffectTick(int duration, int amplifier) {
		// TODO Auto-generated method stub
		return true;
	}
}

 

Please show the code you are using to register the MobEffect.

package com.juder.elementalswords.effect;

import com.juder.elementalswords.ElementalSwords;

import net.minecraft.world.effect.MobEffect;
import net.minecraft.world.effect.MobEffectCategory;
import net.minecraftforge.eventbus.api.IEventBus;
import net.minecraftforge.registries.DeferredRegister;
import net.minecraftforge.registries.ForgeRegistries;
import net.minecraftforge.registries.RegistryObject;

public class ModEffects {
	public static final DeferredRegister<MobEffect> MOB_EFFECTS = DeferredRegister.create(ForgeRegistries.MOB_EFFECTS, ElementalSwords.MOD_ID);
	
	public static final RegistryObject<MobEffect> FREEZE = MOB_EFFECTS.register("freeze", () -> new FreezeEffect(MobEffectCategory.HARMFUL, 3124687));
	
	public static void register(IEventBus eventBus) {
		MOB_EFFECTS.register(eventBus);
	}
}

 

Did you call ModEffects#register in the constructor of your main mod class?

No! Thank you.
