Unity3D – Materials – SetTextureScale – JavaScript
Create a Plane with
– Material with a _MainTex (if you use a diffuse material it is the main color texture)
– TextureScale.js
#pragma strict
function Start () {
// setup Main Texture (scaleX,scaleY)
renderer.material.SetTextureScale ("_MainTex", Vector2(0.5,1));
}
function Update () {
}
Play to see the final result
Unity3D – Mouse Buttons Codes
// Detects clicks from the mouse and prints a message
// depending on the click detected.
function Update() {
if(Input.GetMouseButtonDown(0))
Debug.Log("Pressed left click.");
if(Input.GetMouseButtonDown(1))
Debug.Log("Pressed right click.");
if(Input.GetMouseButtonDown(2))
Debug.Log("Pressed middle click.");
}
Unity3D Game Engine – Get Mouse Button – Physic.Raycast – Destroy GameObject
Destroy Every ‘hit’ GameObject!
Create a scene with:
– Main Camera
– Cube
– Empty Object, assign Destroy.js:
#pragma strict
function Update(){
// if you press Mouse Button
if (Input.GetMouseButtonDown(0)){ // if you press Left Mouse Button -> GetMouseButtonDown(0)
var hit: RaycastHit;
var ray = Camera.main.ScreenPointToRay(Input.mousePosition); // it sends a ray from Camera.main
if (Physics.Raycast(ray, hit)){ // if it hits something
Destroy(hit.transform.gameObject); // destroy every hit object
}
}
}// End Update
Unity3D – GetMouseButton – PhysicRaycast – Get GameObject script Component
Create a scene with:
– Cube, attach the script ‘BoomScript.js’
#pragma strict
function Start () {
}
function Update () {
}
function Boom(){
Debug.Log("Kaboooom!");
}
– Main Camera, attach the script ‘Raycast.js’
#pragma strict
function Update(){
// if you press Mouse Button
if (Input.GetMouseButtonDown(0)){ // if you press Left Mouse Button -> GetMouseButtonDown(0)
var hit: RaycastHit;
var ray = Camera.main.ScreenPointToRay(Input.mousePosition); // it sends a ray from Camera.main
if (Physics.Raycast(ray, hit)){ // if it hits something
// Get Script attached to the GameObject
var boomScript : BoomScript = hit.collider.GetComponent(BoomScript);
if (boomScript != null) {// if it exists
boomScript.Boom(); // execute the function Boom() of BoomScript
}
}
}
}// End Update()
Play, click over the Cube, in the console the message will be ‘Kaboooom!’.
For italian people: come funziona?
1. Se viene cliccato il tasto sinistro del mouse
2. parte un raggio dalla Main Camera
3. se colpisce qualcosa ottieni il Component ‘BoomScript’, cioè lo script BoomScript.js
4. se non è nullo, cioè esiste, avvia all’interno di BoomScript.js la funzione Boom()
5. function Boom() manda il messaggio ‘Kaboooom!’ alla console di Unity3D.
Unity3D – GetMouseButton – PhysicRaycast – Get GameObject tag
Once you have determined that your raycast actually hit something, you can query the name of your ‘hit’ object.
Create a scene with:
– Cube, tag it ‘Player’
– Main Camera, attach the script:
#pragma strict
function Update(){
// if you press Mouse Button
if (Input.GetMouseButtonDown(0)){ // if you press Left Mouse Button -> GetMouseButtonDown(0)
var hit: RaycastHit;
var ray = Camera.main.ScreenPointToRay(Input.mousePosition); // it sends a ray from Camera.main
if (Physics.Raycast(ray, hit)){ // if it hits something
var MyObjectTag = hit.collider.tag; // get the tag of the 'hit' object
Debug.Log(MyObjectTag); // the name of the clicked object
// Do something...
}
}
}
Play, if you click the Cube you will see inside console ‘Player’.
