[1.12.2] TileEntity Container crashing when placed in world.


rafacost

Recommended Posts

Hey guys!

Trying to create a small container that keeps inventory when broke.

When I place the container block in the world it crashes the game.

When I restart the game the block is placed and working as planned.

If I break this block and place it again it keeps the inventory.

The problem seems to be when the block doesn't have an NBT or TE associated with it.

But I can't pinpoint where is the problem because the crashlog doesn't shows nothing about my code.

Could you please take a look?

    • okay i've managed to fix it. looks like i made the stupidest error known to man. i hadn't installed forge to the client, which i assumed only affected the launcher which wouldn't affect me because i used a third party one. evidently not. the more you know
    • tried a fresh install of above and beyond with java 8 installed. got a popup that says "Error: Unable to access jarfile forge-1.16.5-36.2.8.jar". every good programmer knows getting a different error means you've made progress!
