[1.15.2] Container Blocks not working on dedicated server when player is not OP

[Scourrge]

Hi,

today I tried to run my modification on dedicated server and encountered an anomaly when Block's ContainerScreen displays only when player has administration rights (OP) otherwise nothing happens. Could you please point me where could be a problem? In singleplayer opening of Screens works fine. Also on dedicated server if player has OP rights. I don't check if player has OP rights anywhere in my code.

 

EDIT: I debugged a little bit more and found out that when I am not OP I can't even place the block it immediatelly disappears. Moreover when trying to use block while I am not OP the method onBlockActivated is not called at all. 

Thank you in advance

Yes, on like 136 in your code you are returning the wrong thing.

I don't think there is a problem with code. Because in Singleplayer everything works fine. On dedicated server for OP players everything works fine. The only case when modification doesn't behave as expected is when you are not OP and you try to place modification block it immediately disappears. And when you try to use modification block (when placed) to open GUI nothing happens (onBlockActivated method is not even called). So it seems like server is somehow blocking modification for non-OPed players.

 

Biggest portion of my implementation is taken straight from this example https://github.com/TheGreyGhost/MinecraftByExample/tree/master/src/main/java/minecraftbyexample/mbe30_inventory_basic . Implementations like ContainerBlock, TileEntity, Container, Content, Registration events, Screen are all taken from this implementation.

Doesn't the spawn chunk have protection against all non-opped players?

Seems like it. I tried to run further from spawn and it seems working. My bad. Spawn protection was last thing that came to my mind
