This post provides a handy reference guide to go from Scratch’s “Looks” category of code blocks to C# with Unity.

PhD in Germany for Indian Students
Friday February 22, 2019

Getting a PhD in Germany for Indian students can seem complicated, but it really isn’t. According to the latest enrollment data, German universities are home to around 380,000 international students with PhD candidates sharing around 10% of that number. Indian students, as the second largest group of international students in Germany, account for a significant […]

IEnumerator Start()
{
// Optional code here
yield return new WaitForSeconds(1f);
// Optional code here
}

for (int i = 0; i < 10; ++i)
{
// Code to repeat
}

You can simply use the “Update” method of a “MonoBehaviour”:

Studienkolleg in Germany (Prep Course)
Monday October 22, 2018

If you want to study in Germany as a non-EU international student, you must first check if your previous qualification is recognized at German universities. Every school-leaving certificate attained in your country must be compared and translated into German qualification terms otherwise it won’t be recognized. There is a limited list of foreign qualifications assessed […]

void Update()
{
// Code to repeat per frame
}

Or, you can use a “while” loop. Make sure to provide some way to pause execution (like a yield statement in a Coroutine) or you will lock up Unity.

IEnumerator Start()
{
while(true)
{
// Optional code here
yield return null; // wait a frame
// Optional code here
}
}

// "condition" is anything that evaluates to true or false
if (condition)
{
// Code to execute when condition is true
}

// "condition" is anything that evaluates to true or false
if (condition)
{
// Code to execute when condition is true
}
else
{
// Code to execute when condition is false
}

// Optional code here
// "condition" is anything that evaluates to true or false
yield return new WaitUntil(() => condition);
// Optional code here

This is basically a “while” loop where you want the condition to be false:

// "condition" is anything that evaluates to true or false
while (!condition)
{
// Code to repeat
}

You can stop a script by disabling it.

enabled = false;

Or, if you were running a Coroutine you could stop it:

var coroutine = SomeCoroutine();
StartCoroutine(coroutine);
StopCoroutine(coroutine);

There isn’t a “good” equivalent for this, but a possible solution exists based on a pattern Unity has implemented. Whenever a clone is instantiated, the name of the clone will have “(Clone)” added to the end of its name. I only say it isn’t a “good” solution because you can rename an instantiated clone and then wouldn’t have any way to determine that status.

void Start()
{
if (name.Contains("Clone"))
{
Debug.Log("I'm a clone!");
}
}

Instantiate(gameObject);

Destroy(gameObject);
