Unity Top Five Scripts For Every Game Developer Should Know

Small Unity Cheat Sheet

Today We Discuss About

1. Basic Script Structure

2. Input Handling

3. Game Object Manipulation

4. Physics Interactions

5. Coroutines

1. Basic Script Structure

Explain:

Script Class: Defines a script class that inherits from MonoBehaviour.
Variables Declaration: Example of declaring a variable.
Start(): Called before the first frame update, used for initialization.
Update(): Called once per frame, used for continuous game logic.

2. Input Handling

Explain:

Input.GetKeyDown(): Checks if a specific key (e.g., Space) is pressed.
Input.GetAxis(): Retrieves the value of specified input axes (e.g., Horizontal, Vertical) for smooth input.

3. Game Object Manipulation

Explain:

GameObject.Find(): Finds a GameObject by name.
SetActive(): Enables or disables a GameObject.
Instantiate(): Creates a new instance of a GameObject (e.g., a prefab).
Destroy(): Removes a GameObject from the scene.

4. Physics Interactions

Explain:

Rigidbody: Component for physics interactions (e.g., applying forces).
GetComponent<Rigidbody>(): Retrieves the Rigidbody component.
AddForce(): Applies a force to the Rigidbody.
OnCollisionEnter(): Called when a collision occurs, used for collision handling.

5. Coroutines

Explain:

Coroutine: A function that can pause its execution and yield control back to Unity.
WaitForSeconds(): Delays the execution of code for a specified duration.
StartCoroutine(): Starts the coroutine.

🧑‍💻Coding Challenge 05 🎮

Challenge -A game object can Rotate its own axis in the game (x or y or z) with using a small script.

🧑‍💻Coding Challenge 07 🎮

Challenge-In this challenge we have two game objects.If one game object collide with other game object then the second game object will disappear,make a small sound and print console massage.

🧑‍💻Coding Challenge 08 🎮

Challenge-In this Challenge Has main 3 Parts.This game have 2 gameobjects.They are player and powerup system.If the player collect Power Up Then It will destroy.Second one is the player speed increse a small time duration and last the player speed come to normal start value.

🧑‍💻Coding Challenge 09 🎮

Challenge -In this challenge If we press space key then the game object will jump in the game.As well as again we click the space button it will not jump and it will jump only it position on the ground game object.
