Sprites/textures :Instantiate in a loop and load into an array

oldschool

Hi,
I would like to create sprites inside a loop. Is this possible?
I've tried with jumping balls but got nowhere fast. I got attempt to index global

now I've tried with Hierarchy example and get the error main.lua:30: bad argument #1 to 'addChild' (Sprite expected, got nil)

Is what I want possible with sprites or textures? If not then how do you setup scenes with multiple instances of the same object quickly?

a={} dot1tex = Texture.new("dot-1.png")   group1 = Sprite.new()   group1:addChild(Bitmap.new(group1tex))   for i=0,3 do for j=0,3 do local dot = Bitmap.new(dot1tex) dot:setPosition(i * 45 + 10, j * 45 + 60) a[i]=group1:addChild(dot) end end   group1:setPosition(10, 10) for i=0,3 do stage:addChild(a[i]) -- line 30 end

group1:addChild(dot) does not return sprite, you should do

group1:addChild(dot) a[i]=dot

for it to work, but all in all, you can simply add whole group to the stage

stage:addChild(group1)

And second loop is not needed

Hello,

Remember Lua table indexing starts at 1 and not at 0
