Dropping an item on a certain location

[Logiq1]

I'm trying to make a generator type thing where an ingot or diamond or something else drops on top of the "generator"'s location when a player is near a certain type of block. I currently have it working but am unsure of how to make the item drop at a certain coordinate or location, so instead the item drops randomly near the player.

 

on join:
    wait 1 tick
    while player is alive:
        loop all blocks in radius 5 around the player:
            if loop-block is a Block of Diamond:
                wait 3 seconds
                drop a diamond
        wait 1 second

This is what I have currently and it works perfectly fine apart from when I try to put in a location.

Thanks for any help!

this should work:

on join:
    wait 1 tick
    while player is alive:
        loop all blocks in radius 5 around the player:
            if loop-block is a Block of Diamond:
                wait 3 seconds
                set {_loc} to location of loop-block
                add 0.5 to y-coordinate of {_loc}
                drop a diamond at {_loc}
        wait 1 second

but I recommend doing something like this:

function checkGen(plr: player):
    loop all blocks in radius 5 around {_plr}:
        if loop-block is a Block of Diamond:
            wait 3 seconds
            set {_loc} to location of loop-block
            add 0.5 to y-coordinate of {_loc}
            drop a diamond at {_loc}

every 1 second:
    loop all players:
    	checkGen(loop-player)
