    How do I get more than one of the same sprite.

    Hello forums! I have a question that is so basic you'll probably laugh at it, but I know you will help:
    How do I get more than one of the same sprite. And don't say repeatedly doing
    (sprite) = Bitmap.new(Texture.new("ship.png"))
stage:addChild(playership1)
    I mean writing one piece then if you were to say do:
    (sprite):setScale(2.0)
    It would change the scale of all the sprites.

    Thanks in advance. :D

    Edit: BTW The sprite is being made in an animation and ideally I would like all childs of the sprite to be animated.
    Animate code:
    local anim1 = {}
anim1[1] = Bitmap.new(Texture.new("invader2.png"))
anim1[2] = Bitmap.new(Texture.new("invader.png"))
 
local animation = MovieClip.new{
{1,40, anim1[1]},
{40,100, anim1[2]},
anim1[1]:setScale(0.3)
}
 
animation:setPosition(0,-5)
stage:addChild(animation)
animation:setGotoAction(100, 1)
 
animation:gotoAndPlay(1)

      you can write an Invader class inheriting from Sprite where you put the animation code, then with a for loop you place them all on screen.
      Invader = Core.class(Sprite)
 
function Invader:init() --this method corresponds to Invader.new()
--I assume the animation code is working
local anim1 = {}
anim1[1] = Bitmap.new(Texture.new("invader2.png"))
anim1[2] = Bitmap.new(Texture.new("invader.png"))
 
local animation = MovieClip.new{
{1,40, anim1[1]},
{40,100, anim1[2]},
anim1[1]:setScale(0.3)
}
 
animation:setPosition(0,-5)
self:addChild(animation) --adding animation to Invader instance, not to stage
animation:setGotoAction(100, 1)
 
animation:gotoAndPlay(1)
end
 
local maxInvaders  = 5 --how many invaders to place on screen
 
 
local invaders = {} --as we did for bullets: an array collecting a serie of sprites references
invadersLayer = Sprite.new() -- a sprite to put on stage, where you can add all your invaders together so that you can just edit this, and move/scale all sprites together
stage:addChild(invaderLayer)
 
local paddx = 50 --x distance between invaders
for i=1, maxInvaders do --from 1 to maxInvaders, place on invadersLayer
invaders[i] = Invader.new() --create one instance of Invader class
invaders[i]:setX(paddx*i) --set its x position according to its "number" i
invadersLayer:addChild(invaders[i]) --add this instance of Invader to invadersLayer
 
end
      I didn't test this but I think it should work.
      I leave to you the code to place them on different lines :)

      Do I write this in a separate .lua? And what do you mean by "I leave to you the code to place on different line"?

      Ok NVM Prev comment. I used your code as a temp than made several tweaks to it: etc. all sprites moving across the screen scaling eg.

      Thanks for your time! :)
