Hello,

using Rapier 0.11.2 I'm currently trying to understand why my Rigidbodies don't fall asleep (or rather: continuously wakeup)

From reading the changelogs I found that there's something like an activation force for e.g. linvel - this doesn't seem to exist in the javascript API tho.
Is there a way to explictly set a threshold for the rigidbody when to fall asleep?


furthermore setting the translation or rotation on a collider seems to wakeup rigidbodies that are in contact with the collider (even if the collider hasn't changed it's position). When I add an extra check to only call setTranslation if the position has actually changed the Rigidbody does also sleep. Is this expected? Is there a way to prevent having to manually doing this check?

I'm also looking for the ability to set a speed or time threshold for sleeping, sort of like the sleepTimeLimit and sleepTimeLimit options that the Cannon library provides. It doesn't look like Rapier has this but i could be wrong
