I made a drink inventory using a list. The inventory will include water, milk, tea, coffee, and beer in it when I finish it. But right now I've slammed into a mental wall.

In addition to the milk as being a drink, I want it possible for the milk to turn into cheese. Cheese, of course, is not a drink, but a food.

My problem: I don't know how to delete a "milk" item from my list when the item could be ANYWHERE. As far as I know, the list blocks almost all include the need to fill in what number, in this case, the "milk" item is in.

For example, I need something to go in this script:

when milk into cheese button
 clicked
if Drinks ▼
 contains milk
delete 1
 of Drinks ▼

I'll need something different than the "delete 1".

what you have is a good start, but I suggest using some kind of method to go through all of the list items and delete them if necessary. For example,


if drinks ▼
 contains milk
set # ▼
 to 1
repeat until not drinks ▼
 contains milk
if item #
 of drinks ▼
 = milk
delete #
 of drinks ▼
change # ▼
 by 1

This will go through all the items in the list until there is no more milk! big_smile

Use this.


if drinks ▼
 contains milk
set counter ▼
 to 0
repeat until item counter
 of drinks ▼
=milk
change counter ▼
 by 1
delete counter
 of drinks ▼
else
say There is no milk in the inventory.
 for 2
 secs

or


if drinks ▼
 contains milk
set counter ▼
 to 0
repeat until not drinks ▼
 contains milk
change counter ▼
 by 1
if item counter
 of drinks ▼
 = milk
delete counter
 of drinks ▼

I have not tested it, but it should work.

I think I'll try the first one. The second one looks like it will delete all of the milk, which I don't want to do. Either way, thanks!

This will go through all the items in the list until there is no more milk!

If you want to delete 1 milk:


set stop ▼
 to 0
if drinks ▼
 contains milk
set # ▼
 to 1
repeat until stop
 = 1
if item #
 of drinks ▼
 = milk
delete #
 of drinks ▼
set stop ▼
 to 1
change # ▼
 by 1
do other stuff

if you don't need to continue the script just use stop script instead of setting stop.

Are you just trying to get your post count up? You really didn't need to post this. And that's Splodgey.
