Entity Random Spawn

{% hint style="warning" %}

Requires ItemsAdder 4.0.11 or greater!

{% endhint %}

You can make custom entities randomly spawn in your world, exactly how vanilla mobs do.

This is an example to make an example red_zombie spawn.

It will spawn only with a 20% chance of when a vanilla zombie spawns. It will replace the vanilla zombie with the custom one.

It will spawn only in worlds of which name starts by world, between world height 0 and 150 during weather RAIN and with light level from 0 to 10.
