Walking through objects

Hey guys so i am completely new to unity so dont laugh

I have been trying to get my imported character (suited man pack on assets store) which has a 3rd person controller added to it (also on unity assets store) not to walk through walls/objects.

I have tried everything, i have put on every collider etc.

I also have found out that when i delete the box collider off my character (even if it was unmarked in the first place) my character does not move!!

That’s Unity’s Standard Asset Pack for Unity 5.0 which includes a third person character controller.
Maybe try using that one and see if it fixes your problem, otherwise you would need to post the code from your current controller to be able to identify any possible issues.

Does the scene have colliders as well? If it does then it could be a camera issue as you likely have 2 cameras
