# Timers

after(seconds, tag) runs once.

`after(seconds, tag)` runs once. `every(seconds, tag)` repeats.
Both emit `timer(tag)`; `stop_timer(tag)` cancels the timer. Reusing a tag replaces
its timer. Timers belong to the copy, not a player, so include the player id
in a tag for personal timers and cancel them on `leave` as appropriate.

`after`: 0 to 3600 seconds. `every`: 0.35 to 3600 seconds. Tags are limited to
64 characters, and there can be 64 timers in a copy. Timers run on the room tick;
they are not a high-frequency animation loop.
