I'm making a datapack and in it I need to check (in a mcfunction file) if any player (@a) has a specific item in their inventory (minecraft:gold_ingot{coin:1}) if so, I need to run a function (gc:coin_amount). In-game I have used conditional command blocks to achieve this (execute as @a run clear @s minecraft:gold_ingot{coin:1} and then function gc:coin_amount), however I have no idea how to pull it off inside a mcfunction file in a datapack.
Any help would be appreciated.
fill ~ ~-1 ~ ~ ~-1 ~ wool 14fill ~ ~1 ~ ~ ~1 ~ redstone_blocktestforblocks ~ ~-1 ~ ~ ~-1 ~ [x2] [y2] [z2] where [x2] [y2] and [z2] are the coordinates of the target dropper.The dropper on the top is completely unnecessary and is only there because I used this in a tutorial. In the far right command block would be the command you want executed when the two droppers match.
I will test this when I get access to a desktop, but I belive tp @a[x=?,y=?,z=?,r=1] x y z on repeat should work. It worked for me in 1.7, but I haven't tested this on 1.10 yet.

You can store the result of a command with
/execute store. In this case:Then you can use that score for whatever you want. In this case you're just interested in whether it's 1 or more:
As a nice side effect, this also runs the function as every player who matches that condition. If you don't want that, use
/execute if entity @a[scores={gold=1..}] run <command>instead.Also, if you just want to check whether someone has an item (or how much of it), without actually taking it away, use the
/clearcommand with a count of 0.
