You mean like does player have e.g. 6 items of a type in main-hand, right?

If that's the case, wouldn't it be a duplicate of "Itemstack size procedure blocks"? One of the blocks suggested in that ticket is the "Get stack size", which would fill the role.

Yes, to test for the same item in the main-hand, off-hand, hotbar or inventory.

I don't know java but it may be related not sure.

One of the blocks suggested in that ticket is the "Get stack size", which would fill the role.

One can not convert slot contents to itemstack yet, although it is planned, so, for now, this one would be required separately too.

These two will be indeed covered by this ticket: https://mcreator.net/tracker/issue/53366

Testing for multiple items in main-hand.

Testing for multiple items in off-hand.

The other two remain on this ticket.

At this point, this can be done using loops and checking all slots in inventory, but if possible, a more convenient procedure block will be considered for this.
