Pseudo-random array

Questions & Answers
1

I am trying to shuffle strings stored in an array so that they are in a pseudo-random order where a string is not repeated twice in a row. The array contains 5 different strings repeated 5 times each. I have been unable to find any code that does this, only randomization code that can allow for presentation of a string twice in a row. Any suggestions on how to go about this?

You could use Mathf.random(0,string.length) for the random part and an if statement for filtering out already user elements

One possibility

	public string [] _WordsToRandomize = new string[]{"Foo", "Bar", "Word", "Unity", "Answers"};
	public string [] _Randomized;

	void Start ()
	{
		_Randomized = new string[30];

		// take random index from words array
		int rndm = Random.Range (0, _WordsToRandomize.Length);

		// loop through array to fill
		int i = _Randomized.Length;
		while (--i >= 0)
		{
			// take the random word from words array
			string rndmWord = _WordsToRandomize[rndm];
			_Randomized *= rndmWord; // put it in target array*

  •  	// take the first word in the words-array*

  •  	string firstWord = _WordsToRandomize[0];*

  •  	_WordsToRandomize[0] = rndmWord; // put the used word as the first in array*

  •  	_WordsToRandomize[rndm] = firstWord; // ... and the first word replaces the previous random word*

  •  	// take a new random index excluding index 0 that has the previous word*

  •  	rndm = Random.Range (1, _WordsToRandomize.Length);*

  •  }*

  • }*
