Client NPE crash #14

Closed TechStack closed 8 years ago

TechStack commented 8 years ago

Hey looks like you get a NPE crash if you use the building wand and look at an entity. My guess is the MovingObjectPosition is finding the entity instead of the block and passing null to one of your methods :) Hope this helps Cheers

We will check it out. BTW, what version of Not Enough Wands and what version of MC?

TechStack commented 8 years ago

It was in a pack i have created its on curse if you want to use it for testing "TSCraft Custom 1.8.9 pack" version 1.16. It currently uses: notenoughwands -1.8.9-1.2.8.jar forge is 11.15.1.1763

The crash is client side only and will occur when you look at any entity. It was first discovered placing sand that would fall ( falling sand entities ) and later we also had it crash when looking at squid or other players with the wand in hand.

Hope this helps Cheers!

I cannot reproduce this problem. Neither with falling sand, nor with entities like cows. So I'll attempt to do a blind fix based on what I think might be wrong. Will be in next version. Reopen this ticket if the upcoming 1.2.9 version does not fix this bug. Thanks
