Unity 3D Game Engine – Get OS Language
Inside Hierarchy create a scene with:
1. Main Camera
2. GUI Text, attach the script ‘GetLanguage.js’
GetLanguage.js
#pragma strict
function Start () {
// Prints to a guiText the actual language that the system is using.
guiText.text = Application.systemLanguage.ToString();
}
function Update () {
}
NOTICE ToString(); function that converts value to string.
The final result is: Italian
Unity 3D Game Engine – Get Screenshot – Desktop
How to get a in-game Screenshot with Unity 3D
Method 1
NOTICE: CaptureScreenshot is asynchronous. This is because capturing and saving the screen can take awhile.
Inside Hierarchy create a structure with:
1. Some Objects
2. Main Camera, attach the script ‘GetScreenShot.js’
GetScreenShot.js
#pragma strict
function Start() {
}
function OnGUI()
{
if (GUI.Button(Rect(10,10,200,50),"Capture Screenshot"))
{
print (Application. persistentDataPath);
//static function CaptureScreenshot(filename: string, superSize: int = 0): void;
Application.CaptureScreenshot("Pictures/Screenshot.png");
}
}
To test it, inside your Project folder create the subfolder /Pictures
Play it, you will find yourProjectFolder/Pictures/Screenshot.png
The console will print: ‘C:/Users/yourusername/AppData/LocalLow/DefaultCompany/Touch_Move’ on Win 7
You can Use persistentDataPath.
The Application.persistentDataPath is different for various platforms (iOS vs Android), and is the /Documents directory, a read-write path where you can put your downloaded stuff
Use the code:
#pragma strict
function Start() {
}
function OnGUI()
{
if (GUI.Button(Rect(10,10,200,50),"Capture Screenshot"))
{
print (Application. persistentDataPath);
//static function CaptureScreenshot(filename: string, superSize: int = 0): void;
Application.CaptureScreenshot(Application.persistentDataPath+"/Frame.png");
}
}
It will save the image into:
C:/Users/yourusername/AppData/LocalLow/DefaultCompany/Touch_Move/Frame.png

Method 2
Reference: http://docs.unity3d.com/Documentation/ScriptReference/Texture2D.EncodeToPNG.html
Encodes this texture into PNG format.
// Saves screenshot as PNG file.
import System.IO;
// Take a shot immediately
function Start () {
UploadPNG ();
}
function UploadPNG () {
// We should only read the screen buffer after rendering is complete
yield WaitForEndOfFrame();
// Create a texture the size of the screen, RGB24 format
var width = Screen.width;
var height = Screen.height;
var tex = new Texture2D (width, height, TextureFormat.RGB24, false);
// Read screen contents into the texture
tex.ReadPixels (Rect(0, 0, width, height), 0, 0);
tex.Apply ();
// Encode texture into PNG
var bytes = tex.EncodeToPNG();
Destroy (tex);
// For testing purposes, also write to a file in the project folder
// File.WriteAllBytes(Application.dataPath + "/../SavedScreen.png", bytes);
// Create a Web Form
var form = new WWWForm();
form.AddField("frameCount", Time.frameCount.ToString());
form.AddBinaryData("fileUpload",bytes);
// Upload to a cgi script
var w = WWW("http:/localhostcgi-bin/env.cgi?post", form);
yield w;
if (w.error != null) {
print(w.error);
} else {
print("Finished Uploading Screenshot");
}
}
Unity 3D Game Engine – JavaScript – Point and Click Movement – No NavMesh
– UNTESTED –
Create a Sphere (the player) and assign:
PropertiesAndCoroutines.js
#pragma strict
public var smoothing : float = 7f;
private var target : Vector3;
function SetTarget(value : Vector3)
{
target = value;
StopCoroutine("Movement");
StartCoroutine("Movement", target);
}
function Movement (target : Vector3)
{
while(Vector3.Distance(transform.position, target) > 0.05f)
{
transform.position = Vector3.Lerp(transform.position, target, smoothing * Time.deltaTime);
yield;
}
}
Create a Plane (the ground) and assign:
ClickSetPosition.js
#pragma strict
public var coroutineScript : PropertiesAndCoroutines; // richiama lo script sopra
function OnMouseDown ()
{
var ray : Ray = Camera.main.ScreenPointToRay(Input.mousePosition);
var hit : RaycastHit;
Physics.Raycast(ray, hit);
if(hit.collider.gameObject == gameObject)
{
var newTarget : Vector3 = hit.point;
// invia il parametro target allo script PropertiesAndCoroutines
coroutineScript.SetTarget(newTarget);
}
}
Come funziona?
1. ClickSetPosition.js
– al click il RayCast, calcolato da Camera.main definisce un valore Vector3 XYZ di posizione
– il valore viene mandato alla Coroutine con coroutineScript.SetTarget(newTarget)
2. PropertiesAndCoroutines.js
– riceve il valore XYZ
– ferma la Couroutine, se l’oggetto si sta muovendo viene arrestato
– avvia di nuovo la Courotine, l’oggetto si sposterà verso la nuova destinazione.
Unity 3D Game Engine – Orbit Around an Object
Inside Hierarchy create:
1. Sphere
2. Cube and attach GravityScript.js
#pragma strict
public var target : Transform;
function Update ()
{
var relativePos : Vector3 = (target.position + new Vector3(0, 1.5f, 0)) - transform.position;
var rotation : Quaternion = Quaternion.LookRotation(relativePos);
var current : Quaternion = transform.localRotation;
// Spherical Linear Interpolation
transform.localRotation = Quaternion.Slerp(current, rotation, Time.deltaTime);
transform.Translate(0, 0, 3 * Time.deltaTime);
}
Inspector> GravityScript.js> DRAG AND DROP Sphere over var target
3. Play> the Cube will rotate around the Sphere as a planet around the sun.
Unity 3D Game Engine – LookAt Object
Inside Hierarchy create:
1. Sphere and attach MotionScript.js
#pragma strict
public var speed : float = 3f;
function Update ()
{
transform.Translate(-Input.GetAxis("Horizontal") * speed * Time.deltaTime, 0, 0);
}
2. Cube and attach LookAtScript.js
#pragma strict
public var target : Transform;
function Update ()
{
var relativePos : Vector3 = target.position - transform.position;
transform.rotation = Quaternion.LookRotation(relativePos);
}
Inspector> LookAtScript.js> DRAG AND DROP Sphere over var target
3. Move the Sphere using keyboard arrow, the Cube will look at the Sphere
