Unit 3 - Create a basic 2D Game

Because FixedUpdate() runs in sync with the physics system, ensuring consistent Rigidbody2D movement

Because FixedUpdate() runs once per frame and is better for input handling

Because Update() cannot access Rigidbody2D components

Because FixedUpdate() is required when using the new Input System

To abstract player input so it works across different devices

To improve rendering performance

To replace Rigidbody2D physics

To manage scene loading

To ensure changes remain consistent regardless of frame rate

To slow the game down on weaker hardware

To synchronise updates with physics calculations

To detect collisions between objects

To store whole-number values such as lives, scores, or counters

To store values that require decimal precision

To improve rendering performance

To control time-based movement

To expose values in the Inspector for easy tweaking

To improve script execution speed

To prevent other scripts from accessing them

To automatically save game data

To initialize values and references before gameplay begins

To handle physics calculations at fixed time steps

To read player input every frame

To detect collisions between GameObjects
