Double-click actions.

Unity Engine
1

Hey!

I am trying to figure how to utilize double-clicking to get things to happen. I want single-clicking to do one thing, double-clicking to do another, and double-click-and-holding to do yet another. I assume this will involve creative scripting using time differences, but I am a total novice at this. Thanks for any advice!

This might get you started:

var doubleclickTime : float = .5;
private var clickTime : float = -999;
private var doubleclicked = false;

function OnMouseDown () {
	if (Time.time < clickTime + doubleclickTime  !doubleclicked) {
		doubleclicked = true;
	}
	else {
		print ("Click!");
		doubleclicked = false;
	}
}

function OnMouseUp () {
	clickTime = Time.time;
	if (doubleclicked) {
		print ("Doubleclick!");
	}
}

You might want different logic depending on what sort of behavior you’re after exactly. I think that code mimics clicking behavior in the Finder, whereas a website works differently (clicks register on mouseup instead). There’s also an OnMouseDrag function that might be useful, though I don’t know if you’re using OnMouse at all.
