Object Mirroring

Can i mirror my object when i press button?

You can change the direction of the coordinate axes (drawing direction)

  screen.setDrawAnchor( -1,1 )

or

   image = new Image( 100, 100 ) 

   image.setDrawAnchor( -1,-1 )

Or you can just do

if flipped then
  screen.setDrawScale(-1, 1)
else
  screen.setDrawScale(1, 1)
end
screen.drawSprite(...)

. setDrawScale with negative values (works with y input too if you want) reverses. You can even combine it with scaling like setDrawScale(-1.5, 5.3) or something.

thanks
