Exemplary

 So, working as an exemplary student, I notice the menu in

the masterfile for Mario. One begins with tiles0, inVisual Studio

code.

There is a utility fonction to make quads, but no real spritesheet to speak of.

Just a lonely 32x16 piece of tiling whose right half is clear.

The utility function creates a spritesheet on orders form main.

And here main wants a map 20x20.

So what happens: one gets an empty background and a set of tiles to specification.

Below, the x-values will be, while y < 5, draw the Sky, set at 2, hence transparent.

Then, go to town and draw some tiles ie 1.

And there we are: 5 double rows of transparency and the rest, tiles...Modifiable at will!

Moving on to Tiles.1, one needs to change the code for the random 

background. Love2d currently codes for color not to 255 colors, the

RGB requirement. It rather expects a decimal value for that. The

default with no specifications will give that.

It's a fun exercise; one then gets a new background everytime one runs it.

The breakthrough, though, comes from the ability to advance the tiles - with the arrow

 

keys -  giving the impression of game mouvement. Recall that the scene is redrawn

in deltatime within love.draw().
