Question about EntityPlayer.getItemInUse() being Side.CLIENT

Recommended Posts

Is there a reason EntityPlayer.getItemInUse() is flagged @SideOnly(Side.CLIENT) ?

 

Removing @SideOnly(Side.CLIENT) doesn't appear to cause any problems (very limited testing)

Testing on both the built-in LAN server and stand alone dedicated server (through Eclipse) returned the correct item every time.

 

If it has to stay client side only, does anyone know of a server side equivalent?

I'm checking if the item is a food, and stopping the player from eating.

 

 

EDIT:

Found a workaround  :)

 

Using PlayerInteractEvent, I check for right click events, get the current item, see if its a food, cancel the event accordingly.

It also solves the problem of the cake blocks avoiding my previous checks. stops the block from being used but players still get the food value.

I was using the server side instance of the player (checking in LivingUpdateEvent)

but getItemInUse is locked to the client (even though unlocked it works on the server)

 

PlayerInteractEvent works better, it doesn't need getItemInUse and the check doesn't happen as often.

    • i tried that but it says the same error
    • No, and it is in fact broken. Firstly, you never register this type, so it will never work correctly. Secondly, you must not create registry entries in static initializers. You did it correctly above: Use this instead. However this is in the wrong class, as particle types (as all registry entries) must be registered on both sides (client and server). As such doing this in a client-only class will never work right.
    • Every time you post you post in the wrong subforum and I have to move your thread. Please take the hint. This is broken. You must not return null from this method. Use NetworkHooks.getEntitySpawningPacket. You must also only spawn your entity and start riding it on the server.
    • Sorry about the wait, I managed to fix the issue by loading in one of my server providers presets and stealing the jar from that. Sorry about wasting your time.
