Unity 3D Game Engine – Android – Native Camera Access

Inside Hierarchy create the scene with:

1. Main Camera

2. Plane in front of the Camera, attach the script ‘GetcameraImg.js’

GetcameraImg.js

// Starts the default camera and assigns the texture to the current renderer
function Start () {
	var webcamTexture : WebCamTexture = WebCamTexture(); // assign the webcam source to var
	renderer.material.mainTexture = webcamTexture;       // render over material texture webcam source
	webcamTexture.Play();	                             // Play the webcam		
}

function Update () {
   
}

3. You can flip, mirror, rotate the 3D Plane to flip, mirror, rotate the webcam texture!

Unity 3D Game Engine – Get Screenshot – Android

How to get a in-game Screenshot with Unity 3D – UNTESTED

IMPORTANT!!!

Unity> MAIN TOP MENU> File> Build Settings> Player Settings…> Other Settings> Configuration> Write Access> External (SD Card), this setup will create inside Android Device using Windows 7 -> Phone/Android/data/com.Company.LuceDigitale

It this equal the write inside AndroidManifest.xml ->

Method 1

Application.CaptureScreenshot

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

// For Android Devices ONLY
// Attach this script to Main Camera

// File> Build Settings> Player Settings...> Other Settings> Configuration> Write Access> External (SD Card),
// this setup will create inside Android Device using Windows 7 -> Phone/Android/data/com.Company.LuceDigitale
// It this equal the write inside AndroidManifest.xml ->  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

var scoreTextX : GUIText;
var localize   : String;

function Start() {
}

function OnGUI()
{
  if (GUI.Button(Rect(10,10,200,50),"Capture Screenshot"))
  { 
    // debug data path
    localize = Application.persistentDataPath;
    scoreTextX.text = localize;
    // it writes:  /storage/sdcard0/Android/data/<bundle id>/files folder
    
    // We should only read the screen buffer after rendering is complete
    yield WaitForEndOfFrame();
    
    // Application.dataPath DOES NOT have write permission on Android, you need Application.persistentDataPath
    // static function CaptureScreenshot(filename: string, superSize: int = 0): void;
    Application.CaptureScreenshot("Screenshot.png");
    // the file will be saved on: /storage/sdcard0/Android/data/<bundle id>/files folder
  }

How to get GPS coordinates in Unity 3D

Inside Hierarchy create a scene with:

1. GUI Texture
2. Main Camera, attach the script ‘GetGpsCoord.js’

GetGpsCoord.js

#pragma strict

// Hierarchy DRAG E DROP over var GUI Text in Inspector
var scoreTextX : GUIText;
var localize   : String;

function Start () {
        // First, check if user has location service enabled
        if (!Input.location.isEnabledByUser)
            return;
        // Start service before querying location
        Input.location.Start ();
        // Wait until service initializes
        var maxWait : int = 20;
        while (Input.location.status
               == LocationServiceStatus.Initializing && maxWait > 0) {
            yield WaitForSeconds (1);
            maxWait--;
        }
        // Service didn't initialize in 20 seconds
        if (maxWait < 1) {
            print ("Timed out");
            return;
        }
        // Connection has failed
        if (Input.location.status == LocationServiceStatus.Failed) {
            print ("Unable to determine device location");
            return;
        }
        // Access granted and location value could be retrieved
        else {
        localize = Input.location.lastData.latitude + " " +
                   Input.location.lastData.longitude + " " +
                   Input.location.lastData.altitude + " " +
                   Input.location.lastData.horizontalAccuracy + " " +
                   Input.location.lastData.timestamp;
                                      
                   scoreTextX.text = "GPS coordinates "+localize;
        }
        // Stop service if there is no need to query location updates continuously
        Input.location.Stop ();
    }

Hierarchy> Main Camera> GetGpsCoord.js> DRAG AND DROP GUI Texture over var scoreTextX

The final result is:

45.04529 -> latitude
11.72339 -> longitude
0 -> altitude
2099 -> horizontalAccuracy
1396651772.795 -> timestamp
