Controlling GameObjects using components

In the Unity Editor, you make changes to Component properties using the 

 Inspector. So, for example, changes to the position values of the Transform Component will result in a change to the GameObject’s position. Similarly, you can change the color of a Renderer’s material or the mass of a Rigidbody with a corresponding effect on the appearance or behavior of the GameObject. For the most part, scripting is also about modifying Component properties to manipulate GameObjects. The difference, though, is that a script can vary a property’s value gradually over time or in response to input from the user. By changing, creating and destroying objects at the right time, any kind of gameplay can be implemented.
