2D Character capsule collision on Paper Sprite Component

Hi, I’m trying to write simple 2D character class. I used 2D Side Scroller example to try it, but it seems like collision works only for other characters. It doesn’t work on Paper Sprite Components or even on normal Actors with mesh and collision components.
Sample character can normally interact with them but the only difference is Movement Controller. Do I really need to use it? I just want my pawn to move and shot projectiles, nothing else. I don’t need any kind of jumping, swimming etc. things.

Code:
[Header code][1]
[CPP code][2]

Screen:

I want to make my character to collide with those Ledges, just like sample character on this level.

If you know how to solve this problem without enabling Physics then I would really appreciate your help!
