Thats how i learning stuff. But as you can see, I still have a classic Update function. Adding some verticality with the stairs will allow us to experiment with a lot of different and important things when coding our character: The way it collides with objects, the gravity when falling from a distance, and also to test the jumping mechanic if we want one. You could manage the inputs directly in FixedUpdate but you would most likely have inconvenient behaviors. The dash vector depends on 2 variables, the dash distance and the drag. But that is another way of using Player controllers. Site design / logo 2022 Stack Exchange Inc; user contributions licensed under CC BY-SA.

In this example we didnt have a lot of features to code and the Character Controller solution was the easiest one to do, but if we were to implement more mechanics, the Rigidbody would probably be the best way to go. Finally you have Characters. You can see we dont bother ourselves with gravity or drag. 0.
