Hi guys,

I've got some code here where I'm trying to illustrate a set of 5 cards; the last five played. The problem is that they're being displayed in reverse order:

That image shows the start of a game, 4 cards played. The first card played is displayed fully, where as the last (latest) is displayed underneath. The actual ordering is fine, they're in place - just reversed.

Cards being played are added to the pile with a normal table.insert, with no position specified; so they should just be adding the the end of the table, which means (to me at least) that the code should work. Can anyone point me in the right direction with this?

Normally, yes, but you're looping in reverse order. Replace line 3 by:

Code: Select all

for i = #GLOBAL_VARS.CardPile-4, #GLOBAL_VARS.CardPile do

And line 17 by:

Code: Select all

for i =1,  #GLOBAL_VARS.CardPile do

Hope that helps.

By the way, we'd prefer it that you upload a .love when you have a problem in the future. That way we can see if our proposed solution actually works before replying.

Thanks for the help! And I'll remember that in the future, thanks for the info.

I have to ask, what is the deal with the GLOBAL_VARS table? It sounds suspiciously like _G, the "contents" of which can be accessed globally, since they're globals.

Code: Select all

someFunc = function()
    x = 1
end

someFunc()

print(x) -- 1
print(_G.x) -- 1

In Lua, pretty much everything you declare is global unless you specify otherwise (obvious exceptions are function parameters).
