protected void findNearestTarget() {
      if (this.targetClass != PlayerEntity.class && this.targetClass != ServerPlayerEntity.class) {
         this.nearestTarget = this.goalOwner.world.<T>func_225318_b(this.targetClass, this.targetEntitySelector, this.goalOwner, this.goalOwner.getPosX(), this.goalOwner.getPosYEye(), this.goalOwner.getPosZ(), this.getTargetableArea(this.getTargetDistance()));
      } else {
         this.nearestTarget = this.goalOwner.world.getClosestPlayer(this.targetEntitySelector, this.goalOwner, this.goalOwner.getPosX(), this.goalOwner.getPosYEye(), this.goalOwner.getPosZ());
         if (PlayerAssignEvent.PlayerAssignIds.get(PlayerEntity.getUUID(((PlayerEntity) nearestTarget).getGameProfile())) == false) {
            this.nearestTarget = null;
         }
         }
      }

This is in the Goal/AI class. I just copied and pasted the normal NearestAttackableTargetGoal. My inention is as the title states, I want to make a mob that attacks only certain players. The game keeps crashing upon summoning the entity with this goal, even when I remove the this.nearestTarget = null; line. Here is the latest log.

Anyone help with how to do this would be appreciated!

Step one:

Fix this. This is not your package.

 

This is the code that is failing. Something here is null. What is PlayerAssignEvent? wtf is that code? 

I fixed it. I just moved the if statement to a different area in that same file and it worked just fine
