Hi there, I did a timer but I don't know why the arguments into it are executed a lot of time. I want to do that just one time. This timer was given to me in the past by @KarimAKL . Do you have any issue ? <Edit by Moderator: Redacted code to keep passwords safe, never post those, long live configs> BukkitRunnable into the PlayerMoveEvent What I want to do is : The player is detected on the block, wait any time, and execute.
