You ever need a respawn timer for your server?
This is the perfect datapack for you

this datapack will put players in spectator mode for 100 (configurable) ticks then return them to their gamemode and respawn point (does not count deaths in spectator mode, spectator mode deaths will just instantly respawn)

all of its tags/scoreboard variables start with "respawn." so it wont overwrite anything you already have

use /scoreboard players set time respawn.timer <value in ticks> to set the respawn time.

will return you to your previous gamemode after you spectate!

It also is very modable with simple code!


install instructions: just plop it in your world.... thats it. if your world is running already use /reload
