invulnerability data stored internally instead of modifying player data.

just a fix

see effects here - https://github.com/DailyStruggle/Glide/wiki

I've made effects async to reduce server impact.

also added an API function for adding commands.

added sounds, particles, and potion effects via permission

demo -


You can find a full list of sounds here - https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/Sound.html
(there were too many sounds to reasonably add all of them as permissions on startup, so you'll have to copy/paste)
volume and pitch are configurable by percentage (default is 100)

particles here - https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Particle.html
number of particles is configurable

potion effects here - https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/potion/PotionEffectType.html
duration, level, ambient, particles, icon (in that order)

unset invulnerability on player quit
unset invulnerability after n seconds when player has a glide.invulnerable.[n] permission

fixed typo in "invunerable" permission node

added glide.invulnerable permission to make a player invulnerable for the duration of the glide if they are not already invulnerable, and reset the status right after landing.

added glide.fall permission node, to make a player glide if they fall 3 blocks

use glide.fall.[y] to set a different fall distance
