What are the Update and FixedUpdate functions in Unity?

Question

Accepted Answer

Update and FixedUpdate functions are two different methods in Unity used for updating game objects, with FixedUpdate being called at fixed intervals.

Update function is called once per frame and is used for regular updates like input handling and animations.
FixedUpdate function is called at fixed intervals (usually every physics step) and is used for physics calculations and rigidbody updates.
It is recommended to use FixedUpdate for physics-related updates to ensure consistency across different devices and framerates.
