Make Itemstack Unpickable Client Side

[Coder]

I would like to make it so my client can't pick certain items, for example, Cobblestone when it's on the ground.

Something like this should be possible to execute only on the client side?

Out of curiosity, why would you want this client-side? Client-side only mods are usually intended to add some visual interest or other changes to user input, but I can't really imagine why a person would want to restrict themselves from being able to pick up something client side if the server otherwise is allowing other players to do so.

Inventory management, specifically for stuff like mining; sometimes granite and the other stone blocks clutter inventory. Well, this might be why I am just assuming.

No, picking up items is handled server-side.

Isn't it possible to trick the server in thinking my inventory has no space for an item?

no that is handed server side

why do you want to do this ??

the first thing i think of when somebody want to stuff client side is cheating/hacking

I don't see how managing your inventory via not picking up certain items is considered cheating.

[loordgek]

it is giving you (the mod user) advantage over the rest  of the server

It just makes your life a little easier, you won't gain anything from it except not waste time dropping items out of your inventory.

In this case it depends on the server. If it is a survival server that would be left up to the owner, and typically if pop is off then it would be allowed. Now if it was a factions server or UHC, that would be a different case, this would also be useful in a modpack.

No this is not possible, this mod would have to be on both server and client. The way picking up items works is the EntityItem checks if the item is colliding with the player and if so it will try to pick up the item. This all happens on the server and is then synced to the client.
