Examples

Example 1

We create a core instance and a text object that will show if the finger is inside the canvas or not. A loop is set up, which will run 30 times per second and update the text with the current answer to the question.

var canvas = oCanvas.create({
	canvas: "#canvas",
	background: "#ccc"
});

var text = canvas.display.text({
	x: 177,
	y: 140,
	origin: { x: "center", y: "top" },
	align: "center",
	font: "bold 25px/1.5 sans-serif",
	text: "Is the finger inside\nthe canvas?\nNo",
	fill: "#000"
});

canvas.addChild(text);

canvas.setLoop(function () {
	text.text = "Is the finger inside\nthe canvas?\n" +
			(canvas.touch.onCanvas() ? "Yes" : "No");
}).start();
