Synopsis
love.graphics.point( x, y )
Arguments
Returns
Nothing.
Notes
The pixel grid is actually offset to the center of each pixel. So to get clean pixels drawn use 0.5 + integer increments.
Examples
Render a starfield. Note: if you want the points to be crisper,
function love.load()
stars = {} -- table which will hold our stars
max_stars = 100 -- how many stars we want
for i=1, max_stars do -- generate the coords of our stars
local x = math.random(5, love.graphics.getWidth()-5) -- generate a "random" number for the x coord of this star
local y = math.random(5, love.graphics.getHeight()-5) -- both coords are limited to the screen size, minus 5 pixels of padding
stars[#stars+1] = {x, y} -- stick the values into the next available spot in the table.
end
end
function love.draw()
for i=1, #stars do -- loop through all of our stars
love.graphics.point(stars[i][1], stars[i][2]) -- draw each point
end
end
