Hey, you can use the already used InputAxis Events like this (will seperate Cameraview and CharacterMovement):
I am using the third person template on a newish project (<12hours). By default in the template, the mouse controls up and down without changing the characters movement. However, if you move the mouse right or left, the character goes that direction respectively. I have the movement input linked up to Event Tick so the character runs by default. I want to achieve the character running in a straight line no matter which way the mouse is turned. I added a screenshot of the basic third person template code that I made a few edits to for my needs.
You’re the homie
