Obstacles of Random Size

 

 

myObstacles.push(new component(10, x - height - gap, "green", x, height + gap));

I can't find why (x-height-gap) is used for height if you can explain it it will be big help

X - Height - Gap is used so that the the second obstacles reach the bottom of the screen. Though "y" would be a better choice (canvas.height) this is immaterial as the code always runs with the width as larger than the height, which is the requirement for the bottom obstacle.
