Table into a table, reach it to change x,y position

Hi,

I’m making levels for my game but I have so many difficulties to understand all the table in lua, I can make appear all the objects but I can’t change their position individually ,

I can just move the whole group or get random position for all

How can I change the x and y of each object in all #Elements table ?

I would like do something like that but I know isn’t working :

Levels[1].Elements[1].x = 100

&nbsp; &nbsp; local Niveaux = 2 &nbsp; &nbsp; local allElementGame = {} &nbsp; &nbsp; local ShowElementLevel &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; local ElementImages = {"Platform", "nuage"} -- Here in #Levels: Elements[1] is "Platform" and Elements[2] is "nuage" -- I want to change the x and the y of all the object in #Elements but I didn't success to reach them &nbsp; &nbsp; local Levels = { &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {Elements = {1,2}}, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {Elements = {2,1}} &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; } &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; function ShowElementLevel (Niveaux) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; local level = Levels[Niveaux] &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;local Elements = level.Elements &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; for x = 1, #Elements do &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; local Elementlvl = Elements[x] &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; local Element = display.newImage("Images/Element-" .. ElementImages[Elementlvl] .. ".png") &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Element.name = ElementImages[Elementlvl] &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp;Element.Elementlvl = Elementlvl &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp;allElementGame[#allElementGame+1] = Element &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;end &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; end &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; ShowElementLevel(Niveaux) &nbsp;

Levels[1].Elements[1] in your case is not an object. It is the number 1 and Levels[1].Elements[2] = 2

You store the objects in allElementGame table so allElementGame[1].x = 100 will work if there is something at position 1.
