UNITY TUTORIAL | SCRIPTING | GetComponent()

Unity Tutorial | Scripting |Getcomponent()

 

Script itself is a custom game component

also, in a script, we can modify other components such as “RigidBody”, “Collider”, or even another “Script”

to modify components in a script we need variables as a bowl for the component and we need to put the component in the variable by using “GetComponent()”

 

“PlayerControl” Script | Creating a Varaible

• Create a variable “GameManager” as a bowl to bring and use “Gamemanger” script or class in this script

“GameManager” Script | Custom Function

• there is a custom function, “SetGameManagerState()” in “GameManager” script or calss

“PlayerControl” Script | GetComponent()

• put the class in the variable by using “GetComponent()”
• after that, we can use the functionality of “GameManager” class in this script

 

“Player” GameObject | Inspector | Audio Source

• in “Player” GameObject,
  • “PlayerControl” scrip & “Audio Source” are attached
  • we want to use  “Audio Source” in “PlayerControl” Script

“PlayerControl” Script | GetComponent()

• In “PlayerControl” Script,
  • create a variable as a bowl for “Audiosource”
  • put the class by using “GetComponent()”
  • use “AudioSource”

UNITY | PROJECT | 2D PlatFormer | 1. Project Set Up

Importing Sprites

 

Cutting Sprites

 

Creating “Ground”

• Add “Box Collider” to “Ground”

 

Adding “Player”

• Add “Box Collider” to “Player”
• Add “RigidBody2D” to “Player”

Adding “PlayerControl” Script

Physics Working

 

“PlayerControl” Script

• Claim variable for Player movement
  • playerSpeed
  • facingRight as flag
  • playerJumpPower
  • movementX
• in “Update()” method
  • get input to move horizontally by using “Input.GetAxis()”
  • get “RigidBody2D” component by using “GetComponent()”
    • call “velocity” propery to move “Player” with continuous input
  • create “if Statement” for Player’s movment
    • when pressing left and facing right
      • activate “FlipPlayer()” method
    • when pressing right and facing left
      • activate “FlipPlayer()” method
  • Create a Function, “FlipPlayer()”,
    • set the flag, “facingRight” to opposite
    • get the “localScale” property
      • multiply -1 to reverse the direction
    • Don’t forget to update “localScale”

Player Moving

“PlayerControl” Script

• Create a function, “Jump()’,
  • use “AddForce()” to give force upwards to “Player”
• in “PlayerMove()” method,
  • when “Jump” button is pressed, activate “Jump()” method

 

Input Manager

 

Player Jumping too high

 

RigidBody2D | Linear Drag | Gravity Scale

• Set “Linear Drag” 0 to 1 to prevent “Player” from jumping too much
• Set “Gravity Scale” 0 to 10 to prevent “Player” from jumping too much

 

Player Jumping

• Player jumps normally but still it can jump multiple times in the air

UNITY | PROJECT | SPACE SHOOTER 2D | 5. Enemy Bullet & Enemy Shooting

Adding “EnemyBullet” Sprite to the scene to configure

Creating & Adding “EnemyBullet” Script

“EnemyBullet” Script

• Create Variables for “speed”, “direction”, “flag”
• Create a Function to set the Bullet’s Direction, “SetTheDirection(Vector2 direction)”
  • Be careful not to be confused with the names of variable “direction”
    • to differentiate them, put “this.” in front of “direction”(not the argument)
  • normalize the vector to get purely a direction (to make the computing correct and simple)
  • set the flag(the boolean variable) as “True” to activate the codes in “Update()” method
• In “Update()” method
  • the codes will be activated when the flag is set to “True”
  • the position of the bullet is updated every frame by calculating “transform.position” with “direction(Vector2, the result from “SetDirection()”)’
  • if a bullet goes out of the screen, Destroy it
• In “Awake()”
  • every code in “Awake()” is activated before the game starts
  • before the game starts, set “speed” and “ready” with default values

 

Creating “EnemyBullet” Prefab

 

Add “Enemy” Prefab temporally to configure

 

Adding “EnemyGun” to “Enemy” by creating Empty GameObject | Adding “EnemyGun” Script

 

“EnemyGun” Script

• Add a public GameObject variable to use EnemyBullet prefab as a component
• Create a Function to fire bullets from Enemy, “FireEnemyBullet()”
  • get a reference of “Player” by using “GameObject.Find()”
  • the way of detecting a GameObject, “if(gameObject != null)”
  • if “Player” is detected, a bullet is instantiated and its initial position is set
  • how to calculate an aiming direction: Vector – Vector
  • to use “SetDirection()” method of “EnemyBullet” Class, use “GetComponent()” towards “bullet”
• In “Start()” method
  • make “FireEnemyBullet()” activated after 1 second, by using “Invoke()”

 

Don’t forget to add the reference in the Inspector

 

Applying Changes to Prefab

• To apply changes on the prefab, Don’t forget to push “Apply” button in the Inspector
