This is a project to help myself, and others, get up-to speed on Lua and Love2d.
I'm borrowing an idea from Codea: a uniform UI for interactive editing of global variables: parameters. This makes it much easier to understand how the many different options in the love APIs operate.
It's as simple as defining the variable:
scale = 1
and then (inside a setup() function):
params.float("scale", 1, 100)
The parameters are the minimum and maximum value.
In addition, you must add two function calls to your love.update() and love.draw() callback functions:
In addition to the code, there's a number of free and open source sprites, to aid in your prototyping.
