First of all, remove value = Dist.CLIENT The client should not be the one giving items to mobs, that is the job of the server. You can get more details about that at the official forge documentation. Second, you should not use reference equality (==) to check if two strings are equal. In this case, you should not compare strings at all, you probably want to use event.getEntity().getType() to compare entity types. Yes, you should have posted this in the 'Modder Support' forum and not here, but don't worry about it, a moderator can always move it.

I just googled it and saw this video. Had a good chuckle (but yeah that is not in the game). Edit: Gz on your 100th post BlockyPenguin. Perhaps the Hoglins are dancing for you

I would advise against copying code you don't fully understand, since it will most likely introduce bugs. First of all, remove 'value = Dist.CLIENT', since you cannot add potion effects on the client (I believe this was also discussed in the thread I linked). Second, have you tried debugging / checking the logs to find out where and why it crashes? It is very hard for me to stare at a PNG of code trying to detect what is wrong.

A similar question was asked a while ago, maybe the answers there could help you? Here it is.

I don't think hoglins have a built-in 'dance state', so you would have to do the dance animation yourself. How would you even make a boar dance? Shaking its head?

Well, I would imagine the LivingDeathEvent works for the ender dragon like it does for other entities.

You could listen to the LivingEquipmentChangeEvent event, check if the equipped armor is of a specific type, and if so apply the effect to the entity. Then you would also have to detect if the entity unequipped the armor, and if so remove the effect. Alternatively, if the armor in question is your own mods custom armor, you could override onArmorTick() and periodically reapply the potion effect. Here is a recent post (although for 1.16) discussing a similar issue: link

Yes, the unfortunate side-effect of this solution is that it effectively reduces the update rate of the yaw rotation to 20 fps. A more sophisticated method might call super.getYaw() in most cases, and only resort to returning rotationYaw in the case when the rotation goes from 360 -> 0, or similar.

Try moving the line prevRotationYaw = rotationYaw; below the line setRotation(rotationYaw, rotationPitch); You could also try overriding getYaw() to simply return rotationYaw, since getYaw() is what is used to determine the viewport yaw.

Look at the setRain() method in the WeatherCommand class.

Whoops, I did not think about that when I wrote my response :P. If I remember correctly, you can get the equipment that was previously equipped from the event as well. Try checking that the previously equipped item was your custom armor, and the newly equipped armor is not, and only then remove the effect.

When you register your entity type, call the method immuneToFire().

You are approaching this the wrong way I am afraid. You cannot create an explosion on the client-side, and you cannot have mutable static variables like you have. If I were you, I would override the appropriate methods in your boom rod item class (such as onUse(), onItemUseFinish() etc) and create the explosion there. That way you can skip the event subscribers altogether.

Just set the duration to something high (like Integer.MAX_VALUE) to approximate an infinite duration. To solve your other problem, just add an else to the if statement you already have, and use player.removePotionEffect(). You would still have to reapply the effect if it gets removed due to for example milk, as ChampionAsh pointed out.
