• Transform Translation:
  • Pros
    • You’ll have EXTREMELY precise control over movement, acceleration, collisions, and everything
    • You don’t need a Rigidbody (unless you want to call OnTriggerEnter2D, then you need a kinematic RB and collider)
  • Cons
    • More setup as you have to create your own collision detection
    • Does not work with physics forces (ex. RB.AddForce)
  • Notes:
    • Use in Update
    • Multiply by Time.deltaTime to get consistent speed
• RB.MovePosition
  • Pros
    • Precise control over movement, acceleration
    • Collisions work right out of the gate
  • Cons
    • Conflicts with physics forces
  • Notes:
    • Use in FixedUpdate
    • Multiply by Time.deltaTime to get consistent speed
    • Set RB to ‘Interpolate’ for smooth movement
• RB.AddForce
  • Pros
    • Collisions work right out of the gate
    • Works well WITH physics forces
  • Cons
    • Not as precise as other methods. Not good for pixel-perfect platformers for example.
    • More work to get consistent movement that isn’t too floaty up-front
  • Notes:
    • Use in FixedUpdate
    • Does not need to be multiplied by Time.deltaTime.
    • Set RB to ‘Interpolate’ for smooth movement
    • You’ll likely need to set a maxSpeed of some kind, and acceleration/deceleration controls to get your character feeling less slippery.
• RB.Velocity
  • Pros
    • Extremely easy to setup
    • Collisions work out of the gate
  • Cons
    • Overwrites physics forces (can make movement problems difficult to debug.)
  • Notes
    • Use in Update
    • Does not need to be multiplied by Time.deltaTime.
    • Set RB to ‘Interpolate’ for smooth movement
