Unity 3D Game Engine – How to make an android device vibrate
1. Hierarchy> Main Camera> attach the script ‘Vibrate.js’
Vibrate.js
function Update () {
}
// Press button to vibrate START
function OnGUI () {
if (GUI.Button (Rect (0, 10, 100, 32), "Vibrate!"))
Handheld.Vibrate ();
}
// Press button to vibrate END
Protect a Directory with a password using cPanel.
1. Enter as administrator into cPanel
2. Security> Directory Password
3. Directory Selection> Web Root> Go
4. Click the Directory you want to protect
5. Check ‘Password protect this directory’
Name the protected directory: give it a name
Save
6. Go Back>
Create User:
Username: give it
Password: give it
Add/Modify Authorized User
Perfect, try to access the files inside the directory, now you need Username and Password
1. Enter as administrator into cPanel
2. Security> Directory Password
3. Directory Selection> Web Root> Go
4. Click the Directory you want to protect
5. Uncheck ‘Password protect this directory’
6. Remove active users if you want
JS Redirection – IOS – Android
Create in the same folder:
– mobile-detector.html
It this the javascript that detects the device type
– ios.html
The page for IOS devices
– android.html
The page for Android devices
– error.html
An Error page
mobile-detector.html

Unity 3D Game Engine – be or not be kinematic, this is the problem…
When we will create a pick up game object, do we need a kinematic or a non-kinematic object?
1. Create a Cube (PickUp) as ‘Prefab’ to easy duplicate it, with:
SOLUZIONE 1: senza ‘Rigid Body’, lo considera un ‘Collider Statico’, come un muro, e quindi calcola e salva in cache la posizione una volta per tutte, questo ha senso per risparmiare calcoli in caso di un oggetto che non si muove. Se il nostro cubo ruota Unity salva in cache ogni volta la nuova posizione per ogni frame occupando risorse di sistema.
– Box Collider -> check ‘Is Trigger’ -> così non si effettuano calcoli fisici perchè il ‘Trigger’ rileva solo le collisioni senza causare reazioni fisiche
OPPURE
SOLUZIONE 2: applicando un ‘Rigid Body’, lo considera un Collider dinamico, e non salverà dati in cache, occupando meno risorse.
a. Rigid Body> Disabilitare ‘Use Gravity’ per non far cadere l’oggetto. L’oggetto risponde ancora alle sollecitazioni provenienti da altri Collider.
b. Rigid Body> Abilitare ‘Is Kinematic’ per non far calcolare a Unity le reazioni alle sollecitazioni provenienti da altri Collider e ottimizzare il consumo di CPU. Un oggetto ‘Is Kinematic’ può essere spostato utilizzando la funzione ‘Transform’. Questo setup è tipico delle piattaforme mobili di un videogioco ‘platform’.
Unity 3D Game Engine – Android – Accelerometer – RAW Data – Translate and Object
Inside Hierarchy create:
– Main Camera
– GUI Text X
– GUI Text Y
– GUI Text Z
– Cube (Game Object), attach ‘AccelerometerTest.js’
AccelerometerTest.js
#pragma strict
// Hierarchy DRAG E DROP over var GUI Text in Inspector
var scoreTextX : GUIText;
var scoreTextY : GUIText;
var scoreTextZ : GUIText;
function Update () {
var dir : Vector3 = Vector3.zero; // Shorthand for writing Vector3(0, 0, 0)
dir.x = Input.acceleration.x;
dir.y = Input.acceleration.y;
dir.z = Input.acceleration.z;
scoreTextX.text = "acceleration.x: " + dir.x;
scoreTextY.text = "acceleration.y: " + dir.y;
scoreTextZ.text = "acceleration.z: " + dir.z;
}
Hierarchy> Cube> Inspector> AccelerometerTest.js assign GUI Text to public var scoreText
Here the final result:
dir.x = Input.acceleration.x; from 1 to -1 -> example: 0.1234567 or -0.1234567
dir.y = Input.acceleration.y; from 1 to -1
dir.z = Input.acceleration.z; from 1 to -1
To translate the Cube using Accelerometer data (basic):
AccelerometerTest.js
#pragma strict
function Update ()
{
transform.Translate(Input.acceleration.x, 0, -Input.acceleration.z);
}
To translate the Cube using Accelerometer data (advanced):
AccelerometerTest.js
#pragma strict
// Move object using accelerometer
var speed = 10.0;
// Hierarchy DRAG E DROP over var GUI Text in Inspector
var scoreTextX : GUIText;
function Update () {
var dir : Vector3 = Vector3.zero; // Shorthand for writing Vector3(0, 0, 0)
dir.x = Input.acceleration.x;
scoreTextX.text = "acceleration.x: " + dir.x;
// clamp acceleration vector to unit sphere
if (dir.sqrMagnitude > 1)
dir.Normalize();
// Make it move 10 meters per second instead of 10 meters per frame...
dir *= Time.deltaTime;
// Move object
transform.Translate (dir * speed);
}
