Unity collider components

- [Instructor] In order for our character…to effectively interact with the scene,…we need to put a couple of different elements in here…so that our character doesn't run through walls for example.…So we do need to set up some collisions…on all the objects within our scene.…So what are are colliders?…Well, if you recall,…the key main thing within Unity…is this idea of GameObjects.…So if we go into our environment here,…and we take for example one of these walls.…This is a prefab…so it's comprised of many different little pieces in here.…

So what we want to do is be able to set up a way…that we can't walk through those walls in there.…So there are a couple ways that we can do this.…We can go down into the GameObjects,…So I have this Wall One picked,…I'm just going to hit f to focus in or frame over towards that.…And what we can do is just take a look…at the different components available here.…So really quickly underneath the physics area…in the Add Component menu,…we can see that we have a Box Collider,…Sphere, Capsule, Mesh, Wheel, and Terrain Collider.…
