Timer problem

Joszko · 2024-12-01T13:29:47.812Z

Hey, im making a .net8 backend + ef core for my project. It's my first time using "advanced" timers and I don' know how to implement it. To begin with I have 3 models: - Food - User - BoostType (modal) User can use Food to gain boost (from BoostType) for certain amount of time - eg. for 3 min he have +20 health. After this 3min boost should have be gone. How to implement this? Cookies is way to go?

i wouldn't use cookies, this is a state of the character, right? (if this is a game and there is a playing character)

so only one boost can exist at a time?
if so then if you have a service to manage the state of the character it should be pretty straightforward to add a timer
