Notes
The pixel grid is actually offset to the center of each pixel. So to get clean pixels drawn use 0.5 + integer increments.
Points are not affected by love.graphics.scale - their size is always in pixels.
Examples
Render a starfield
function love.load()
local screen_width, screen_height = love.graphics.getDimensions()
local max_stars = 100 -- how many stars we want
stars = {} -- table which will hold our stars
for i=1, max_stars do -- generate the coords of our stars
local x = love.math.random(5, screen_width-5) -- generate a "random" number for the x coord of this star
local y = love.math.random(5, screen_height-5) -- both coords are limited to the screen size, minus 5 pixels of padding
stars[i] = {x, y} -- stick the values into the table
end
end
function love.draw()
for i, star in ipairs(stars) do -- loop through all of our stars
love.graphics.point(star[1], star[2]) -- draw each point
end
end
