Bossbar Timer

This mod adds a customisable bossbar timer.

You can also set actions for it to run when the timer is over.

Commands:
/eventtimer set <seconds> – Sets the duration, stops the timer, and resets it to that duration. Accepts 1–86,400 seconds.
/eventtimer title <text> – Changes the text shown beside the remaining time on the bossbar.
/eventtimer color <color> – Changes the bossbar colour. Options: purple, pink, blue, red, green, yellow, white.
/eventtimer sound <sound_id> – Sets the sound played to players when the timer finishes. Sound IDs have autocomplete. The default is minecraft:entity.ender_dragon.growl.
/eventtimer sound off – Disables the finish sound.
/eventtimer start – Starts a fresh countdown from the full duration, even if one was already in progress.
/eventtimer pause – Pauses the countdown and hides the bossbar.
/eventtimer resume – Continues from the remaining time and shows the bossbar again. A finished timer needs start instead.
/eventtimer stop – Stops the countdown, resets it to the full duration, and hides the bossbar.
/eventtimer status – Shows whether it’s running, the time remaining, and the selected finish action.
/eventtimer action none – Sets the finish action to do nothing. The configured finish sound still plays unless you turn it off separately.
/eventtimer action message <text> – Sends your message to all players when time runs out.
/eventtimer action command add <command> – Adds a command to run when time runs out. You can add up to 16; they run in the order added. Command autocomplete works while typing.
/eventtimer action command list – Shows the stored commands in their execution order.
/eventtimer action command clear – Removes all stored commands and sets the action to none.
