How to smooth analog input values in real time?

Development Programming & Scripting C++

By default, Unreal Engine reads the exact and precise values of an analog stick. This, if “Orient Rotation To Movement” is active, causes jittery rotation when using a controller, since all the tiny changes in the thumbstick value affect the movement.

How could i make these values smooth? Should i use interpolation? Should i change something in the deadzone settings? And if the answer is interpolation, how could i divide the analog stick in just, let’s say, 8 valid input directions to interpolate between eachother? Should i do this math in a separate UPlayerInput class or should i implement this in my Character class?Nobody seems to adress this, i haven’t found anyone with a solution, yet.

Here’s a video i made showing what smooth rotation looks like compared to the default Unreal Engine:

What you are looking for is named as “Use Controller Desired Rotation” in the CharacterMovementComponent, then customize the Rotation Rate above it:

The problem is that, in your case, you’re using WASD. There is no jittering when i use WASD in my project as well. I’ve already tried toggling that option on and off and the jitter is still there when using a controller, it does’t change anything
