Function

Synopsis

love.graphics.line( points )

Arguments

table points
A table of point positions, as described above.

Returns

Nothing.

Examples

Draw the outline of a simple trapezoid

function love.draw()
   love.graphics.line(200,50, 400,50, 500,300, 100,300, 200,50)   -- last pair is a repeat to complete the trapezoid
end

Draw a line from the center of the screen to the mouse pointer

w = love.graphics.getWidth() / 2   -- half the window width
h = love.graphics.getHeight() / 2   -- half the window height
function love.draw()
   local mx, my = love.mouse.getPosition()  -- current position of the mouse
   love.graphics.line(w, h, mx, my)
end

Draw a zigzag line from a single table

sometable = {
   100, 100,
   200, 200,
   300, 100,
   400, 200,
}
function love.draw()
   love.graphics.line(sometable)
end
