I want to create a continuous press button - so that an event continues to
happen as long as the button is pressed. I can't see how this can be done

You can use the button.LongClick block, but it doesn't trigger until you let go.

I believe you can also use a canvas and a timer...  In the canvas, you would have to have an image of your button.  In the timer fired event, you'd have to check the touch properties of the canvas.  That's just a guess though... I've never tried it.  You'll have to experiment a bit.

you could use Canvas.TouchDown for starting your event and the Canvas.TouchUp for stopping your event

Taifun's right... and during that time, enable a timer and do all of your stuff there, until the finger is lifted and you disable the timer.
