How do I Incorporate Lists into my Scratch Game?

Question

I want to incorporate a list for my tycoon game, but I do not know how. I tried a lot of ways and failed each time. How can I incorporate a list into my scratch.mit.edu cash tycoon game? I am thinking of having an investment feature but I do not know how to use a list for something like that. I attached an image of my current code: https://i.stack.imgur.com/xbjmo.png

Answer 1

have three lists:

1. a list of all investment options(names)
2. a list of their price incressis(the same order as the first list)
3. a list on what investments you have(the names)

repeat every ? seconds:
now loop over the last list and based off of the item number of the first list add $ based off the second one

Answer 2

Here's a simple way to write it (scratchblocks format):

[scratchblocks]
forever
add (foo) to [list1 v]
...
add (foo1) to [list2 v]
...
add (foo2) to [list3 v]
...
end
[\scratchblocks]

Here's an image:

The foo, foo1, and foo2 operators here are defined as:

foo	foo1	foo2
Adding the list of all of the investment options that there are in your tycoon game	The list of their increasing prices (which would be in the same order as which foo is defined	The list of the investments that you currently own (doesn't necessarily have to be in the same order as foo/foo1)

Hope this helps!
