Just call the drawing function several times with different coordinates.

Code: Select all

local image = love.graphics.newImage("myImage.png")
function love.draw()
    -- Draw the same image twice in different places.
    love.graphics.draw(image, 0, 0)
    love.graphics.draw(image, 50, 90)
end

The same goes for drawing a rectangle, in case you're asking about shapes rather than images.

Code: Select all

function love.draw()
    -- Draw the same rectangle twice in different places.
    love.graphics.rectangle("line", 10, 20, 80, 80)
    love.graphics.rectangle("line", 100, 120, 80, 80)
end
Although in actual practice you wouldn't want to hardcode your coordinates like that. You'd want to use variables instead to be able to update the size, etc. Something like this:

Code: Select all

local box = {}
box.x1 = 10
box.y1 = 20
box.x2 = 100
box.y2 = 120
box.w = 80
box.h = 80

function love.draw()
    -- Draw the same rectangle twice in different places.
    love.graphics.rectangle("line", box.x1, box.y1, box.w, box.h)
    love.graphics.rectangle("line", box.x2, box.y2, box.w, box.h)
end
That way you're drawing 2 boxes with the same color, width, and height. The only thing that changes is the location you draw them at, and that can be changed just by updating the coordinte variables.

Make the object in the object! (actually table in table)

Code: Select all

object = {
  x = 0, y = 0, w = 20, h = 40,
  image = love.graphics.newImage("myImage.png"),
}

box1 = {
  x = 80,
  y = 30,
  object = object,
}

box2 = {
  x = 200,
  y = 300,
  object = object,
}
If the object has own x and y, then just use it as

Code: Select all

for i, box in ipairs ({box1, box2}) do
  local x = box.x + box.object.x
  local y = box.y + box.object.y
  love.graphics.draw(box.object.image, x, y)
end
Otherwise just the position of that box.
