1.20.4 Solved 1.20.4 Block entity Use() event places block for short period of time

[Bunnly]

Hello, I have a block entity and I made it so it places a item into its input slot when you right click it. But when I right click with a block, it places the block and the block disappears shortly after and the block is inside the block entity. How can I prevent the short block placing?

Your question is unanswerable.

If you want help with your code, you need to put something on github that reproduces the problem.

We need to see everything in context and maybe run it for ourselves if the issue is not obvious.

 

Guess (I shouldnt have to guess):

Since this sounds like a ghost block getting created on the client and it sounds like it works properly on the server?

You are not returning the correct InteractionResult from the client side Item.useOn(), so the game goes onto the next step

which is to "simulate" the placing of the block for a BlockItem giving the player instant feedback.

Since the server side does have the correct code, the change to the block entitiy's inventory causes a chunk update to be sent to the client which won't have that placed block

and so the ghost block then disappears.

But I don't think you need it for this usecase?

You do have the

Note that handling things differently on the client vs server may cause desynchronizations!

I fixed it by removing the !pLevel.isclientside()
