    if tool of event-player is wooden shovel:
        cancel event
        set {_block} to block at location of event-block
        set {_shovel} to tool of event-player
        remove 1 durability from {_shovel}
        wait 10 seconds
        if {_block} is air:
            set {_loc} to location of {_block}
            set {_loc} to {_loc} with y + 1
            if {_loc}'s block is air:
                set {_loc}'s block to dirt```
