I created this system so I could use it on my server, but as it’s basic I decided to make it available to the public as well.
Basic explanation:
The player will start with level 0 and 0 respect. Every 1 hour the player will receive 1 respect (you can change this in config.lua) and when they reach their total respect, which in this case is level 0 and 10 respect, they will rise to level 1 and receive a reward (you can choose this in config.lua).
Very basic system, I will make future updates like adding for QBcore and more notifications
