[1.16] Get light level of entity


BliX5

Recommended Posts

If we take a look at a class like AbstractSkeletonEntity, this snippet determines if they should burn:

public void livingTick() {
   boolean flag = this.isInDaylight();
   if (flag) {
      ItemStack itemstack = this.getItemStackFromSlot(EquipmentSlotType.HEAD);
      if (!itemstack.isEmpty()) {
         if (itemstack.isDamageable()) {
            itemstack.setDamage(itemstack.getDamage() + this.rand.nextInt(2));
            if (itemstack.getDamage() >= itemstack.getMaxDamage()) {
               this.sendBreakAnimation(EquipmentSlotType.HEAD);
               this.setItemStackToSlot(EquipmentSlotType.HEAD, ItemStack.EMPTY);
            }
         }
         flag = false;
      }
      if (flag) {
         this.setFire(8);
      }
   }
   super.livingTick();
}

However this also requires we look at isInDaylight() in MobEntity:

protected boolean isInDaylight() {
   if (this.world.isDaytime() && !this.world.isRemote) {
      float f = this.getBrightness();
      BlockPos blockpos = this.getRidingEntity() instanceof BoatEntity ? (new BlockPos(this.getPosX(), (double)Math.round(this.getPosY()), this.getPosZ())).up() : new BlockPos(this.getPosX(), (double)Math.round(this.getPosY()), this.getPosZ());
      if (f > 0.5F && this.rand.nextFloat() * 30.0F < (f - 0.4F) * 2.0F && this.world.canSeeSky(blockpos)) {
         return true;
      }
   }

   return false;
}

And finally, isDaytime() in World:

public boolean isDaytime() {
   return !this.func_230315_m_().func_241514_p_() && this.skylightSubtracted < 4;
}

And there's the light level. So altogether you'll need to add code like these three for your entity.

I have some code, but it doesn't seem to work:

public void livingTick() {
    if (this.isAlive()) {
        boolean flag = (this.shouldBurnInDay() && this.isInDaylight()) || this.isInLightLevel();
        if (flag) {
            this.setFire(4);
        }
    }
    super.livingTick();
}

protected boolean isInLightLevel() {
    return world.getLightValue(this.getPosition()) >= 8;
}

Any help?
