Background rotating instead of character rotating when walking left

Hello Unreal Developers! I am an Unreal newbie, working in 4.12.5 I need help!

I’m trying to make a blueprint (paper character) walk right or left. When it walks left, the blueprint flipbook should rotate 180 so it faces left. When it walks right, it should rotate 0, so it faces right again. Attached are my event graphs and project settings for input and maps/modes.

I am having 2 problems:

The paper character blueprint doesn’t rotate to face left, or move left, when the left arrow or “a” key is pressed. Instead, the background rotates and scrolls left. The background is a PaperTileMapActor on a Level map. I get why the background is scrolling left, to give the illusion the character is moving. But how can I make the character flip, and not the background? Do I have to feed the character into or out of the Get Controller or Set ControlRotation blocks? If so, how can I do that? Or is there another method that would work better? The maps and modes set the Default Pawn Class to Char1.
The AxisMovement doesn’t stop. I read that Axis Movements keep going, after you stop giving the input (key press, etc.) Can I add to the event graphs, to stop the Axis Movement when the input stops? If so, how? Or is there a better way to get simple right and left movements based on user inputs.

Thanks for taking a look at this!

i can’t help you fully as the topic is paper 2d but you can stop axis by doing this

and about rotation , if your character haves a camera maybe that would be rotating too as the whole actor rotates and rotation won't move right ,left as the character needs a flip not rotation

I know this was a few years ago, but maybe it’ll help someone out. This sounds like the exact problem I was having with my paper 2D side scroller! Luckily I just figured out my problem.

Try going to your paper character blueprint and click on the springarm component. In the details panel to the right, scroll down to “Camera Settings” and uncheck “Inherit Yaw.” This way the camera won’t rotate around 180 deg when the character does. Hope this helps someone!
