NullPointerException when trying to use GetDefaultState().WithProperty


Javisel

Recommended Posts

Due to the recommendations of some modders on the Modded Minecraft discord i've moved from initializing my items and blocks in class to making Object Holders and initializing them in Registration.

After this change however, any block with an IProperty that has getDefaultState invoked will produce a nullpointerexception and I have no idea why. Currently I have a workaround by initializing them in class again but this defeats the purpose of moving to object holders.

Any reason you decided not to show your CropCornBottom class?

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

Because your block fields are not getting initialized by the ObjectHolder system. Aka the registry names you've given them dont match the field names you have.

 

IE. CROP_CORN_TOP does not equal corn_crop_top.

VANILLA MINECRAFT CLASSES ARE THE BEST RESOURCES WHEN MODDING

Forge and vanilla BlockState generator.

I lower cased it to perfectly match it's registry name and it still doesn't function. Same error.

Look at the order of the words. It doesnt care about capitalization in your field name.
