That's probably it. blocks[1][1] would screw up if blocks[1] had no value?

What's wrong with this line? The compiler says "attempt to index field '?' (a nil value)".

blocks[a] = love.physics.newBody(world, 50 + (20 * a), 50 + (20 * b), 0, 0)

Thanks.

What does the math.floor() function do?

All it is is changing the value of a variable called text... does text actually represent something in the renderer?

So if I wanted to make a changing text on screen, what should I use?

I've been using Lua for about a year, but I just downloaded Love. Are you saying love.graphics.print() returns the text object?

Is there a way to edit the text and position of a love.graphics.print() string? If not is there another type of onscreen text?
