Connect a lifecycle to a trigger, then set its delay setting to “1.” Also, set the trigger’s active scope to “player.” Connect the trigger to a new wire repeater. Connect the new wire repeater to the trigger. This will create an infinite trigger loop. Connect the trigger to an overlay. Then, place a property device. Set it to “Seconds Survived” and set it to a number property. In the overlay, make this block code.
If you would like this to show on the leaderboard, in Map Options, set the leaderboard to show a property. If you need the timer to stop running, deactivate the trigger.
@FersionSpeedy , would you like an explanation on how this works so you can replicate it easily in other maps?
