C# I've learned throughout dissertation

Here's a list of the C# syntax I learned throughout this dissertation:

Function purpose	Syntax
Spawning an object	Instantiate(object_name,transform.position, Quaternion.identity);
Removing an object	Destroy(gameObject);
Controlling the position of an object	object_name.transform.Translate (x position, y position, z position);
Moving an object	var vel = rigidbody2D.velocity; vel.x = object_speed;  rigidbody2D.velocity = vel;
Referring to a particular object	GameObject.Find("object_name");
Referring to a tag	CompareTag ("tag_name");
Collision detection	void OnTriggerEnter2D(Collider2D);
Returning a random number from a specified range	Random.Range(minNum, maxNum);
Accessing a variable from another class	GameObject variableName = GameObject.Find("object_name"); Class_Name classVariableName = variableName.GetComponent<Class_Name>();
Calling a function from another class	objectVariableName = GameObject.Find("object_name").transform; objectVariableName.gameObject.SendMessage ("Spawn",null,SendMessageOptions.RequireReceiver);
Calling a class every so seconds	InvokeRepeating("function_name", startTime, repeatitionTime);
Adding an OnClick listener	Input.GetMouseButtonDown(0);
Reloading a level	Application.LoadLevel(0);
Spawning text	GUI.Label(new Rect(x position, y position, x size, y size), "text");
Setting the game orientation to portrait	Screen.orientation = ScreenOrientation.Portrait;
Playing audio	if (!audio.playOnAwake){ audio.Play(); }
Adding a swipe input	if(Input.touches.Length > 0){  Touch t = Input.GetTouch(0);  if(t.phase == TouchPhase.Began){   //save began touch 2d point   firstPressPos = new Vector2(t.position.x,t.position.y);  }  if(t.phase == TouchPhase.Moved){ //use .Ended for slower response time   //save ended touch 2d point   secondPressPos = new Vector2(Input.mousePosition.x,Input.mousePosition.y);        //create vector from the two points   currentSwipe = new Vector2(secondPressPos.x - firstPressPos.x, secondPressPos.y - firstPressPos.y);        //normalize the 2d vector   currentSwipe.Normalize();   //swipe left   if(currentSwipe.x < 0 && currentSwipe.y > -0.5f && currentSwipe.y < 0.5f){    rightSwipe = false;    leftSwipe = true;   }   //swipe right   if(currentSwipe.x > 0 && currentSwipe.y > -0.5f && currentSwipe.y < 0.5f){    leftSwipe = false;    rightSwipe = true;    if (!audio.playOnAwake){     audio.Play();    }   }  } }
Adding a drag input	//when using mouse Vector3 touchPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);    // get the current position of the player GameObject Vector3 originalPos = this.transform.position;    // replace the x coordinate with the x of touched pos. originalPos.x = touchPos.x;    // set the player position to the modified one this.transform.position = originalPos;
Adding a highscore	public int score; public int highscore; //retrieve highscore highscore = PlayerPrefs.GetInt("High Score"); //set new highscore if(score > highscore){  highscore = score;  PlayerPrefs.SetInt("High Score", highscore); }
Adding a restart button	if(GUI.Button(new Rect((Screen.width / 2) - 160,(Screen.height / 2) - 40, 320, 80), "Again?")) {  Application.LoadLevel(0); }
