Hello. You are definitely right, this is a pretty large typo, thank you for pointing it out to us.

I have not read all of this tutorial, but based on the context I suspect the broken line

"this.items[x][y].gridPositi x, y: y};"

is supposed to look like this

"this.items[x][y].gridPosition = {x: x, y: y};"

What this is doing is giving each item an object named "gridPosition", and that object has 2 properties, x and y which are set equal to the current x and y given by the for loops. Hopefully this is right and it helps.

I will inform my master about this, he will likely respond here if I am incorrect with the above :)

Thank you. Another bug is on tutorial page "Loading Image" at:

Note that for this to work you'll need a file called clubs.png (download it here)

When you click on "download it here" it not works

Thanks

Thanks for reporting both problems, I have now fixed them.

Let us know if you find any more :)
