This is how i do scrolling. You can use it too! Just give credit. It's really easy to use! 1.Custimize the 'Player' sprite, call the costume normal1 2. Copy that costume and call it sensor 3. Edit the sensor costume, go to the box tool use any color, and drag from one corner to the other covering all of the costume. shave off 1 pixel on the right and left sides 4. Copy and edit the sensor costume. Round out the bottom 2 corners. now select the bottom half and move it up. the higher you move it up, the steeper hills it will be able to walk on. 5. Give credit and enjoy! Note: you can delete the feet sprites and hand if you would like. If you need any other help using it then ask it in the comments! by Mikeono102. Some rights reserved.
