Hello Tarun,

I would suggest using JavaScript's setInterval and clearInterval functions for that and subscribing to the touchmove and touchend events. Something like this:

var updateTimeInMs = 10;
var intervalId = -1;

function handleTouchMove(e)
{
	if (/* the touch is within the bounds of your joystick image */)
	{
		if (intervalId === -1)
		{
			intervalId = setInterval(
				function()
				{
					World.yourModel.translate.x += 0.01;
				},
				updateTimeInMs
			);
		}
	}
}

function handleTouchEnd(e)
{
	clearInterval(intervalId);
	intervalId = -1;
}

You still need to control the direction of movement and do the same thing for the y component of the translation, but I think this code snippet should get the point across well enough.

Kind regards

Daniel
