UNITY | PROJECT | 2D PlatFormer | 2. Camera & Death

“CameraSystem” Script

• Create Variables for Player, and Camera’s Scope
• in Start() method,
  • find player by using FindGameObjectwithTag()

 

“Main Camera”

“CameraSystem” Script

• in LateUpdate() method,
  • create x & y variable for the position of Main Camera
    • Put the x & y values of Player in those x & y
    • Clamp the x & y with min & max values
      • Main Camera will move based on Player‘s Position
      • when Main Camera reaches at the position of Min or Max Values, Main Camera stops there

Main Camera following but clamped

 

Adding Box with Box Collider

 

Adding Ground2 with Box Collider

“Box”

 

Creating “Hole” with “Box Collider”

Creating and Adding “PlayerHealth” Script

 

“PlayerHealth” Script

• Create died bool variable as Flag
• in Start() method,
  • Set the Flag as false
• in Update() method,
  •  if Player‘s y position is below than -7,(Player falls down), show the log

 

Player Falling

PlayerHealth Script

• Create a Coroutine
  • Create Die() as IEnumerator
  • Start the Coroutine with Die() by putting StartCoroutine() in Update() when Player died
  • don’t forget to put yield and return in IEnumerator

CoRoutine Working

“PlayerHealth” Script

• change IEnumerator Die()
  • load the main scene when this IEnumerator is called by using SceneManager.LoadScene()
  • Don’t forget to yield return null

Scene Loaded well

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
