Walking 'through' objects

For my simple game, I am walking right through this cuboid. How can I set this up so I cannot walk through the cuboid?
Also, my students have games that are very similar. THey can walk through walls in a maze in some games, and can’t walk through walls in a maze in a different game. How do you code these objects so you can or cannot walk through them?!

Hi @Kelly_Nickell,

if you set your camera movement to Fly, you will not collide with other objects.
In order to collide with everything and not go through walls, you can use Walk camera movement.

Hope that helps
