C# I've learnt from Square Drop

The point of my dissertation is to learn C# at a level which will allow me to create my own simple 2D mobile phone games, as well as become an employable person in the coding industry (the list of job adverts I looked at can be found here). I'm aiming to do so by creating two prototypes which will be easy to learn and hard to master. Here's a list of C# commands that I've learned after creating the first prototype - Square Drop:

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(); }

This adds up to 16 pieces of code I have learned and used throughout the production of Square Drop. I have also used plenty of boolean, GameObject, and int variables, however having learnt how to use those already before the dissertation, I didn't include them in this list dedicated particularly to C#.

After possible Square Drop iterations due to feedback from my playtesters, I'm hoping to then create another prototype, and learn more code.
