Minecraft – How to remove the glint from Debug stick (1.14 Java)

Yes many power tools and special armor can be enchanted. This may not be working as intended, so keep in mind future patches and updates may remove your enchantments. Use an anvil and an enchanted book of your requested effect, and voila!, your new drill or chainsaw now has Fortune I! Keep in mind that if you enchant an item that runs on an internal battery, and you allow that battery to run dry, the enchantment will be lost.

I personally do this to my Advanced Diamond Drill every game.

Instead of trying to debug this complicated arrangement of tags, I basically rewrote your function, maybe that already fixes your problem:

scoreboard players set @s itemCounter 0
execute at @e[type=item,nbt={Item:{id:"minecraft:rotten_flesh",Count:64b}},distance=..4] if block ~ ~-0.5 ~ soul_sand run scoreboard players add @s itemCounter 1
execute if score @s itemCounter matches 4 run tag @s add fleshPresent

scoreboard players set @s itemCounter 0
execute at @e[type=item,nbt={Item:{id:"minecraft:bone",Count:64b}},distance=..2] if block ~ ~-0.5 ~ quartz_block run scoreboard players add @s itemCounter 1
execute if score @s itemCounter matches 4 run tag @s add bonesPresent

This uses the old method of making every entity you're testing for increase a shared score by 1 each. This is not as nice for performance as I would have hoped, usually 1.13 has nicer ways to do things like this, but maybe someone else has an idea how to do it better.

What I assume went wrong in your original function:

• The items sink into soul sand, so you have to check for ~ ~ ~ instead of ~ ~-1 ~ to test for the block they are in, instead of the one they are on, which would be the one below the soul sand.
• You started with if block …, which means that the block would be checked for whoever runs the function. Since you didn't mention who executes this function, I assume it's the player. But it actually doesn't matter much, because you're testing for being on quartz and also for being on soul sand, which one entity can't be both at the same time.
