What is RunService, and why do we use and why is it useful?

Hey there, I know what RunService is but I want to know where is RunService used?

Currently when I see RunService it's only events like e.g. Heartbeat. How is that example used in scripting?

An example of it being useful is on FPS frameworks. I use RenderStepped instead of Heartbeat, and I need RenderStepped so that it can render every single Lerp of the framework. Dovydas1118 1495 — 4y

Technically Heartbeat is useful, but I use other keywords for Heartbeat, that are similar. If you want to know more go to Developer.Roblox and check out RunService and Heartbeat, RunService is basically a long list of stuff that roblox allows you to do and also can check if you're in studio, in game etc. RunService while using : which connects a function to a Variable, RunService.Heartbeat which is an Event, and iit runs on a variable frequency. If the game is running 40 fps the heatbeat will fire 40 times a second and the step argument is 1/40th of a second.
