Final answer:
The code in Start() is executed once for initial setup, such as setting variables or initializing components. The code in Update() runs once per frame, handling dynamic actions like reading player inputs or updating object positions. Both functions are essential in the game development process.
Step-by-step explanation:
The difference between code listed between the braces after Start() and code listed between the braces for Update() in a game development context (like Unity) is about when and how often each block of code runs. The Start() function runs once, when the script is first initialized. It's typically used to set initial conditions, such as setting variables, or to perform setup operations that are required before the game starts. For example, finding components on the game object or initializing game parameters.
In contrast, the Update() function runs once per frame and is used for code that needs to be checked or executed regularly. This often includes handling user input, updating positions of game objects, or checking for certain conditions within the game loop. As such, it is more dynamic and tends to handle more conditions that can change over time.
Examples of code that would make sense to include after Start() are:
- Initializing a player's health to a starting value.
- Setting up a reference to a component, like a Rigidbody or Collider.
Examples of code to include after Update() are:
- Reading input from the player to move a character.
- Checking for game events, like the player reaching the end of a level.
