1 year ago This code is an error log of a Minecraft server, which contains a NullPointerException. The reason for the exception is that in the line of code net.seanomik.tamablefoxes.versions.version_1_19_2_R1.EntityTamableFox.a(EntityTamableFox.java:574), the method net.minecraft.world.entity.EntityLiving.co() is called, but the method net.seanomik.tamablefoxes.versions.version_1_19_2_R1.EntityTamableFox.getOwner() returns null, resulting in a NullPointerException.
The purpose of this code is to attack an entity, but the entity being attacked is a tamable fox, and the attacker is not the owner of the fox, so a NullPointerException occurs during the attack.
I am not the plugin author, I can only explain the problems that appear in the log, I hope this can help you.
