Input.GetKey

• Input.GetKey – using for while the user holds down the key
• Input.GetKeyDown -using for when the user presses the key down
• Input.GetKeyUp – using for when the user release the key up

UNITY TUTORIAL | SCRIPTING | Update() and Fixed Update()

UNITY TUTORIAL | SCRIPTING | Update() and Fixed Update()

Update()

• Update() is called per frame on every script that uses it
• Update() is called before rendering a frame
• Update() is used for anything that needs to be changed or adjusted regularly happens here
  • moving non-physics object
  • simple timer
  • receiving input
• Update() interval times vary
• If one frame takes longer to process than the next frame, then the time between update calls will be different

FixedUpdate()

• FixedUpdate() is called on a regular timeline
• Fixedupdate() is called before performing any physics calculation
• FixedUpdate() will have the same time between calls
• FixedUpdate() interval times are consistent
• Immediately after FixedUpdate() is called, any necessary physics calculations are made
  • FixedUpdate() is used for regular updates
  • adjusting physics (RigidBody) Objects
