How to add the ability to squat?

In your ACharacter, you can use the Crouch() and UnCrouch() functions. Just ensure that you allow crouching first with GetCharacterMovement()->GetNavAgentPropertiesRef().bCanCrouch.

Hi, all! I use standard 3rd person controller in my project, but I new in UDK and I don’t know how to add the ability to squat. Give me at least an idea of how this can be done. Sorry for bad English. Thanks in advance!

This is what I need! Thanks!
