…Components in Unity are very valuable pieces…for adding in game play and interactivity.…A component is, as the name suggests, part of something.…And you're actually already using them.…We'll put a component, like we did on the first podium, on the second and third.…Selecting that podium object.…And choosing either from the top menu Component>Physics>Box…Collider, or down on the bottom, picking the last podium, scrolling…down and choosing Add Component>Physics>Box Collider.…

What we're doing here is adding on a…component that dictates some element of game play.…In this case, instead of using a mesh collider, because we don't really…need to collide with every face of…this, we're adding the simplest collider possible.…A box collider.…Defining the overall volume as something we cannot pass through.…And this is easier for the game engine to think about as we're playing.…The idea of a component then, is it's a piece of an…object or attached to an object that is part of the game play.…Components are attached to game objects and we need to think of them in that way.…
