Help with wall collision in RPG!

[SolgaleoGaming]

So, I'm new to making games and am learning while I'm making my RPG. So, I managed to get collision working, but I've found a few bugs I have no idea to fix seeing as I'm new to all this and have no idea how anything other than simple stuff works. The player collides with backdrops above him and below him just fine, but can't properly collide with walls, because the player can't move in the other direction if they touch a wall on the left or right, so for example if the player walks into a left wall they can't move right to walk away and vice-versa. I've tried all the different settings for collision, and the ones that work best at the moment are no fine detection and player sticks to obstacles. Removing stick to obstacles makes it worse. My player uses the built in 8 directions movement and the only code so far at all is 'When touches backdrop, stop'. Obviously this doesn't apply to backdrops I haven't set to obstacles. What's different with a wall that makes this problem happen with it and not above or below collision, and can someone tell me how to fix it? Thanks a lot, this is really stopping the game from continuing production!

I don't know how Fusion's built-in obstacles work but in general when a person collides with a wall you need to do three things - stop him, move him away from the wall (so that he is no longer colliding), turn him around so that he is now facing the other way.

For example you'll put his position to x.position+2 or x.position-2 depending on which wall just to break the collision event - else that collision event keeps running and your player is stuck in that loop.
