physics::wakeIslandOf
void wakeIslandOf(Registry &registry, const ContactCache &cache, entt::entity start)
Wake every body that's currently in the same contact island as e.

void wakeBody(Registry &registry, entt::entity e)
Wake a single body (e.g.

physics::updateSleep
void updateSleep(Registry &registry, const SleepConfig &cfg)
Update each body's sleep state from its current velocities.

physics::SleepConfig::linearThresh
float linearThresh
Linear velocity below which a body counts as "still".
