Operators

Listing 1.2 (page 43)

Operators should be “=” not “-“.

transform.localScale.x = transform.localScale.x + growthRate;
transform.localScale.y = transform.localScale.y + growthRate;
transform.localScale.z = transform.localScale.z + growthRate;

Thank you John H. and Howard W.

Chapter 4

Listing 4.18 (pg 212-213)

Formatting error and duplicate if statement if(Input.GetKey(“space”))

The complete aim.js file:

#pragma strict
var cannonball:GameObject;

function Update ()
{
    if (Input.GetKey ("up")) //if up key is pressed
    {
        //rotate upward around the side axis
	this.transform.RotateAround (this.transform.position, this.transform.right, 20 * Time.deltaTime);
    }
    if (Input.GetKey ("down"))
    {
        //rotate downward around the side axis
       this.transform.RotateAround (this.transform.position, this.transform.right, -20 * Time.deltaTime);
    }
    if (Input.GetKey ("right"))
    {
        this.transform.RotateAround (this.transform.position, this.transform.forward, -20 * Time.deltaTime);
    }
    if (Input.GetKey ("left"))
    {
        this.transform.RotateAround (this.transform.position, this.transform.forward, 20 * Time.deltaTime);
    }
    if(Input.GetKey("space"))
    {
        //each loop the space is down increase the strength
        (Camera.main.GetComponent("strengthMeter") as strengthMeter).shotStrength =
	   (Camera.main.GetComponent("strengthMeter") as strengthMeter).shotStrength + 0.01;
    }
    if(Input.GetKeyUp ("space"))
    {
        var cannonball:GameObject = Instantiate(cannonball,this.transform.position, this.transform.rotation);
        //use built up strength to influence the shot
	var strength = (Camera.main.GetComponent("strengthMeter") as strengthMeter).shotStrength * 10000;
        cannonball.GetComponent.().AddForce(this.transform.up * strength);
        //set strength back to 0 after a shot
        (Camera.main.GetComponent("strengthMeter") as strengthMeter).shotStrength = 0;
    }
}

Avoiding and Collecting

Step 5. (Page 219)

Typo. 50 points not 20 points.

“Play. When the character runs over the chest, its health will improve by 50 points….”
