CharacterMovement RotationRate does not change speed of rotation

Hello there!

I’ve been playing around with creating a simple AI which just uses pathfinding to follow the player around.
Now I’ve run into a problem with the “Rotation Rate” on the “CharacterMovement” component. No matter what I set the value to it still rotates extremely slowly towards the direction of travel.

These are my settings:

The Blueprint inherits from “Character”.
I’ve also set “Use Controller Rotation Yaw” on the Pawn to false.

I have no idea why this doesn’t work but I presume it’s something rather simple.

Thanks in advance!

Hello there,

I never figured out why it was rotating super slowly so I decided to just handle it’s rotation manually with Blueprint.
What I do is I take it’s velocity vector and I multiply it by 1000, I then use this new vector I calculated and the actor location to get a look at rotation, I then break the rotation and reconstruct it using only the Yaw as I don’t want any of the other axis to affect it. Lastly I use an interpolation between my actors current rotation and the new rotation I just calculated which makes it turn nice and smoothly.

Here’s an image of the Blueprint.

Have you unchecked Use Controller Rotation of character’s Class Defaults?

I think this must still be a bug - even in 4.11. I’ve unchecked Controller Rotation and checked Orient Towards Movement, expecting it to respect Rotation Rate but it still doesn’t work. No matter what value I put in - it rotates with the same fast speed.

You need turn on the “UseControllerDesiredRotation” on the CharacterMovementComponent.

I had the same problem, i.e., adjusting the Rotation Rate in my AI’s Movement Component had no effect.

My solution:

  • In the Character Blueprint Defaults: Uncheck “Use Controller Rotation Yaw”
  • In the Character’s Movement Component: Check “Orient Rotation to Movement”.

After that, adjusting the movement component’s rotation rate (Yaw) works perfectly!

Cheers to you! This helped me perfectly! Thank you

How do I set up a function with delta time on my graph? Is iths set up in the constriction script or the event graph?

Hi JobsDone94,

If you need a function with “delta time”, you can set it up on the Event Graph. Right Mouse Click on your event graph and type “Event Tick”. You’ll get an event that’s called every frame with “Delta Seconds” as the parameter.

Works for me! thanks !
