Rotate a display object (user controlled)

#1

Anyone have any code that will enable the user to rotate a display object (such as a Movieclip)?
I mean, I know how to rotate the object myself, with code, but I need code that will enable the user to have the ability to use their mouse to rotate something like a square or triangle.

First you need to put your shape into an empty container sprite so its center point equals the top-left of the container. This will make your shape rotate around its center.
Afterwards add a MOUSE_DOWN event listener to your shape. Inside its callback function get the current x position of your mouse pointer and store it in a variable.
Finally add a MOUSE_MOVE event to the stage and update the rotation of your shape depending on the difference between your mouse’s initial and the current x position.
Here’s some code:
package;

import openfl.display.Sprite;
import openfl.Lib;
import openfl.display.Sprite;
import openfl.display.Shape;
import openfl.events.MouseEvent;

class Main extends Sprite
{
	private var square:Sprite = new Sprite();
	private var xPos:Float;
	private var oldRotation:Float;
	private var mouseDown:Bool = false;

	public function new()
	{
		super();

		var shape:Shape = new Shape();
		shape.graphics.beginFill(0xff0000, 1);
		shape.graphics.drawRect(0, 0, 100, 100);
		shape.graphics.endFill();
		square.addChild(shape);
		shape.x =-50;
		shape.y =-50;
		addChild(square);
		square.x = square.y = 200;
		square.addEventListener(MouseEvent.MOUSE_DOWN, pressed);
		stage.addEventListener(MouseEvent.MOUSE_UP, released);
		stage.addEventListener(MouseEvent.MOUSE_MOVE, rotate);
	}

	private function pressed(e:MouseEvent):Void
	{
		xPos = stage.mouseX;
		oldRotation = square.rotation;
		mouseDown = true;
	}

	private function released(e:MouseEvent):Void
	{
		mouseDown = false;
	}

	private function rotate(e:MouseEvent):Void
	{
		if (mouseDown)
		{
			square.rotation = oldRotation + stage.mouseX - xPos;
		}
	}
}
