I made these commands
this command sets a ver to count all jumps by all players
/scoreboard objectives add didjump stat.jump particular player Jumps
this command sets up a var to use as a display
/scoreboard objectives add trackjump dummy trackjump
this command adds one to each player that has already jumped and puts it in the display var
/scoreboard players add @a[score_didjump_min=1] trackjump 1
this command only happens in sequence after the above command goes off; it removes the jump from the last count so that the total doesn't increment constantly unless the player is still jumping
/scoreboard players remove @a[score_didjump_min=1] didjump 1
Then I display that score on the list board when you hold tab, however I ONLY want a specific player to be tracked and am unsure how to write the commands, so far I have tried to modify the @a in the above commands and it then tracks the players name with an @ sign in front of it not the player itself.
