Hi. I made a custom entity, but I want to add a spawn egg for it. But whenever and wherever I register the spawn egg it still crashes.

Here is following crash report:

So I thought that the variable FAKE_WITHER was still null so I tried putting it after I built and registered the entity but it still crashes.

Help would be appreciated.

I'm not sure what you try with FAKE_WITHER, but here is the an link to an old topic about spawn eggs. There is also an up to date implementation of mine:

https://github.com/Silverminer007/MoreOre-1.16/blob/master/src/main/java/com/silverminer/moreore/common/objects/items/ModSpawnEggItem.java

If this isn't what you were looking for post a github or so for code to get an idea of what you've tried

Yes this is exactly what I needed. Thank you!!
