Position of the coins

Hey!

Why does it goes from 0 to 800 horizontally, and from 0 to 600 vertically? I mean I get the zero bit, but how does he know the limit (800 and 600) did he set this up? if so, where or I can see this?

Many thanks!

Hi Silvia,

800 X 600 is the size of the window (or canvas) in pixels. I imagine Dave did specify those dimensions himself, but Iā€™m not sure in the code where.
