Unity3D – Lights Cookies

Unity3D – Lights Cookies

Assign Light Cookie

Light Cookies are grayscale textures you use to control the precise look of in-game lighting.

0. MAIN TOP MENU> GameObject> Create Other> Spotlight, project the light over a plane

1. MAIN TOP MENU> Assets> Import Package> Light Cookies

2. Project> Standard Assets> Light Cookies> FlashLight DRAG AND DROP over Spotlight> Hierarchy> Light> Cookie

Create Light Cookie

To create a light cookie for a spot light:

Paint a cookie texture in Photoshop. The image should be greyscale. White pixels means full lighting intensity, black pixels mean no lighting. The borders of the texture need to be completely black, otherwise the light will appear to leak outside of the spotlight.
In the Texture Inspector change the Texture Type to Cookie
Enable Alpha From Grayscale (this way you can make a grayscale cookie and Unity converts it to an alpha map automatically)

Unity 3D – Camera – Third Person Control

Unity 3D – Camera – Third Person Control

1. Create a ball that rolls over a plane

2. Creare a Camera with:
– CameraController.js

#pragma strict

public var player : GameObject;
private var offset :  Vector3;

function Start () {
offset = transform.position;
}

function LateUpdate () {
//LateUpdate is called after all Update functions have been called. 
// This is useful to order script execution. For example a follow camera should always be implemented in LateUpdate because it tracks objects that might have moved inside Update.
transform.position = player.transform.position + offset;
}

2. Hierarchy DRAG AND DROP ‘ball’ GameObject over Inspector> CameraController.js ‘player’ variable slot.

Unity 3D – Get Axis – rigidbody.velocity

Unity 3D – Get Axis – rigidbody.velocity

1. Create a Plane (Ground) with:
– Mesh Collider

2. Create over the plane a Sphere with:
– Mesh Collider
– Rigid Body
– PlayerController.JS:

#pragma strict
 
function Start () {
 
}
// Theese variables are public to make the code easy-reusable
// You can setup theese variables from Inspector
var speed : float;

function FixedUpdate () {
     // Get User Input START
     var moveHorizontal : float= Input.GetAxis ("Horizontal");
     var moveVertical : float= Input.GetAxis ("Vertical");
     // Get User Input END

     var movement : Vector3= new Vector3 (moveHorizontal, 0.0f, moveVertical);
    rigidbody.velocity = movement * speed;
}
