Hi @kHynnS
Maybe a simple trace , set the distance to just in front of the player and if it hits the wall objects then set a boolean that you can check in the movement code. If true dont allow walking if false allow. Make sure you set the boolean to false if the trace hit is false.
You may have to tweak to distance a little as you test so suggest you turn on the trace visibility a few secpnds or maybe permanent until you happy
