    NOW LIST A CONDITION FOR THE TRANSITION TO HAPPEN
  12. Click on the plus sign
  13. Drop Down and select Speed
  14. Put 0.1 in the box (speed is greater than 0.1)(this means that the character will be walking forward)
  15. Look above the graph for the words HAS EXIT TIME
  16. Uncheck (to disable) If you leave it on, then the animation will transition to another after a few seconds) We want the transition to occur only when it meets the condition.

    REPEAT THE PROCESS – MAKE A NEW TRANSITION (from walk forward to idle)

  34. We need a reference to our Animator (8:34)
  35. Under the Public Class Type
  36. Private Animator
  37. Call it anim;


    private Animator anim;       //reference to the animator 
  38. Need two float variables, one for speed and one for direction

    private float playerDirection;        // variable to store direction coordinate values you will
                                                            receive from the players input
    private float playerSpeed;            // variable to store speed coordinates
                                                            receive from the players input 

NEED TO INITIALIZE THE VARIABLE

  1. Inside the Start Function type 

// Get the reference from the Animator
anim = GetComponent<Animator>( );       //get component from the current gameObject

 

  1. UPDATE FUNCTION

    This is where the change in states happen


 // Get user input

playerDirection = input.GetAxis(“Horizontal”);

playerSpeed = input.GetAxis(“Vertical”);

anim.setFloat(“Direction”, playerDirection);

anim.setFloat(“Speed”, playerSpeed);
