Check overlap between two rectangles

var xOverlap = Math.abs(rect1.x - rect2.x) <= Math.max(rect1.width, rect2.width);
var yOverlap = Math.abs(rect1.y - rect2.y) <= Math.max(rect1.height, rect2.height);

Calculate the angle of shooting
shapes.point.x = shapes.point.x + shapes.point.velocity * Math.cos(angle / 180 * Math.PI);
shapes.point.y = shapes.point.y + shapes.point.velocity * Math.sin(angle / 180 * Math.PI);
