Hi Wegg, Welcome to the Forums,
I just took a look at this and was able to create the look behavior you’re describing.
This is how I modified the first person template character:
One important distinction is between Axis and ‘Bool’ events. The ‘Add Yaw/Pitch’ nodes like to be fed really small values every frame. If you put a ‘print string’ after the “Triggered” pin on IA_Move you should see it triggering every frame the button is pressed. (Also, if you print the ‘Action Value’ variable you’d see the value of ‘1’ being sent to the nodes every frame)
Hope that helps!
