How can I change textmesh to a random text snippet?

Hello! I’m trying to change the text of a textmesh GameObject to a random text snippet from an array of text snippets when the game starts. I’m very inexperienced with code, but here’s what I have so far:

function Start () {
GetComponent(TextMesh).text = ("hello"||"good day"||"what's up");
}

I’ve tried finding the answer, but I’ve only found examples with number ranges. Thank you in advance!

First, you’ll need a collection of items to choose from. There are many different types of collections you can read about, but the simplest for now is a built-in array:

var snippets = ["hello", "good day", "what's up"];

Second, you need to pick a random item from your array. We’ll use Unity’s Random.Range function:

//random number between 0 and length-1
var index = Random.Range(0, snippets.Length);

Third, you assign the value:

GetComponent(TextMesh).text = snippets[index];

Putting all of that together:

function Start() {
	var snippets = ["hello", "good day", "what's up"];
	var index = Random.Range(0, snippets.Length);
	GetComponent(TextMesh).text = snippets[index];
}

If any of this confuses you, remember that you can always look up programming tutorials around the net. It’s slow going, at first, but you’ll get better at it with time.
