Building games in Unity using GameObjects and components.

Everything we can see in Unity IDE's Scene is a GameObject. GameObjects are the building blocks of Unity. A GameObject on its own doesn't do anything. We add things called components to GameObjects to change how they look and behave. A component tell Unity what the GameObject does, such as move or make a sound.

A Prefab is a template GameObject that we can make copies of.

All GameObjects have a Transform component`. The Transform component holds data about where the GameObject is in the Scene, how it rotated and how it scaled.

Update vs FixedUpdate vs LateUpdate:

Update():

• Called Every Frame
• Used for regular updates such as: Moving Non-Physics objects, Simple Timers, Receiving Input
• Update interval times vary

FixedUpdate():

• Call Every Physics Step
• Fixed Update intervals are consistent
• Used for regular updates such as: Adjusting Physics (Rigidbody) objects

LateUpdate():

• Called after all Update functions have been called.
