Draw objects on screen.
Contents
Function
Synopsis
love.graphics.draw( drawable, x, y, r, sx, sy, ox, oy )
Arguments
Drawable drawable
- A drawable object.
number x
- The position to draw the object (x-axis).
number y
- The position to draw the object (y-axis).
number r (0)
- Orientation (radians).
number sx (1)
- Scale factor (x-axis). Can be negative.
number sy (sx)
- Scale factor (y-axis). Can be negative.
number ox (0)
- Origin offset (x-axis). (A value of 20 would effectively move your drawable object 20 pixels to the left.)
number oy (0)
- Origin offset (y-axis). (A value of 20 would effectively move your drawable object 20 pixels up.)
Returns
Nothing.
Notes
love.graphics.draw() anchors from the top left corner by default.
You can specify a negative value for sx or sy to flip the drawable horizontally or vertically.
The pivotal point is (x, y) on the screen and (ox, oy) in the internal coordinate system of the drawable object, before rotation and scaling. The object is scaled by (sx, sy), then rotated by r around the pivotal point.
Examples
Draw an image at 50 by 50 pixels
function love.load()
hamster = love.graphics.newImage("hamster.png")
x = 50
y = 50
end
function love.draw()
love.graphics.draw(hamster, x, y)
end
