Spawn a splash potion with an effect

[Steverixxi]

Hi, I am trying to spawn a splash potion with a specified potion effect (e.g. Slowness) with PotionEntity. I also already have an Potion Object but how do I get the PotionEntity to "have" my Potion or EffectInstance?

Thanks in advance

PotionEntity potion = new PotionEntity(world, player);
potion.setPos(playerPos.getX(), playerPos.getY() + 20, playerPos.getZ());
ItemStack splashPotion = new ItemStack(Items.SPLASH_POTION, 1);
EffectInstance potionEffect = new EffectInstance(Effects.BLINDNESS, 500, 100);
Potion potionToSet = new Potion(potionEffect);
PotionUtils.setPotion(splashPotion, potionToSet);
potion.setItem(splashPotion);

This is the code I am trying to use, but it only spawns a splash potion without any effects.

you can't use an effect that has no item

if you want to use an effect that doesn't have a potion registered by vanilla, you have to register it yourself
you can find all registered potions in the Potions class
