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
