Just did this so I can share here lol: do //1 to get your coordinates and then do /particle explode 100 60 -100 5 5 5 500
The 100 60 -100 is the //1 location Set it on an /ac to repeat every 5 seconds--don't use too much or it will crash the players and lag like mad. Have fun experimenting...
It would be cool to make a command that when you harvest wheat, melons, carrots, etc. you get money for it? Kind of complex but seems like a fun challenge.
