Why isn't my Pawn moving?

I believe I implemented all the code needed for my Pawn to accept input and move. I have tried input with Keyboard/Mouse as well as Controller. Am I missing something?

I don’t know what ABasePawn is, but the implementation for APawn::AddMovementInput is as follows:

Are you sure that your pawn has a movement component?
Have you tried debugging this line to see if GetMovementComponent() returns a nullptr?

I apologize for the very late reply. I made a rookie mistake (I’m very new to game dev/c++) and made a class that inherited from my custom APawn class ‘BasePawn’ rather than create a class that inherits from ‘ACharacter’ lol. It was missing the movement component. I just created a new Character class, rewrote the Input code, and it worked!!
Thank you for your help!!

No worries - I think you’ll find that these things happen more often than you’d like :joy:

Oh I feel like I’ve many so many mistakes in such a short time since I’ve started haha.
Can’t wait to become a lot more experienced!!
