Hello, I was working at an Animate script (similary to the script whitch is created in the character when a player spawns) and I saw the original Animate script uses things like UserSettings():IsUserFeatureEnabled(“UserNoUpdateOnLoop”). What are all the strings avaible?

You can browse through a list of Roblox FFlags through Eryn’s FFlag Watcher. It’s got a nice user interface and utilities to better your browsing experience. Through here, look for any FFlags that are prefixed with “User”. Any FFlag starting with User (e.g. UserCameraToggle) can be picked up by IsUserFeatureEnabled.
