SleepLess

MixinBooter and The Impossible Library are required dependencies

SleepLess is a mod that takes inspiration from the sanity mechanic from Don't Starve as well as the real life effects lack of sleep can have on you and adds some creative flair to them. The idea was to go more along the psychological horror route and make something actually cool out of sleeping (or lack thereof) since vanilla phantoms in 1.13+ are annoying at best

Sleep Debt
Sleep debt is what controls all of the effects present in the mod. You can gain sleep debt by not sleeping enough during the night (the eqivalent of less than 5 hours) or pay it off by getting more than enough sleep. The sleep debt gained/lost is scaled based on how many hours are slept with 1 full day being added if you don't sleep at all and 3 full days paid off if you sleep through the entire night. The max values gained/lost are configurable

The Effects
Here is a list of all the different currently implemented effects. Almost all are configurable

faster hunger drain
slower walking speeds
slower mining speeds
faster drowning
incremental chances for random ambient sounds to play
quieter sounds
denser render distance fog
closer fog
"heavy breathing" (dynamically changes FOV but this is disabled by default)
dimmer lights
loss of color
the ability to see phantom entities
the ability to get attacked by phantom entities
night terrors

Effect Scaling
Contrary to the vanilla system of not sleeping for 3 days, SleepLess works on a 10+ day schedule for the most part. For the first few days of sleep debt gained you won't really notice much difference, but as your chronic lack of sleep continues, you start getting some bigger changes like phantom visibility at 5 days, the chance for phantoms to be aggressive at 7.5 days, loss of color and brightness at 8-9 days, and the chance to have night terrors at 10+ days. Most of the effects also scale slowly but can keep scaling as your sleep debt increases too

Other Effects
SleepLess adds 3 unique effects, though only 2 have actual uses. The first is the Tired effect that you get once you have at least 1 day of sleep debt. The second is the Insomnia effect which prevents you from sleeping while the effect is active. The final effect is Phased which lets you phase your walls, ceilings, & floors if you are sneaking. The phased effect has a specific config option regarding which blocks you are allowed to phase through.
