alice-teacher Lists in Alice 3

[Vanderhyde, James]

Are you asking about removing items programmatically, or from the interface? In the interface, you can remove items, but it is hidden. If you click on an item in the array, the item changes color and an X appears in the corner. Click the X to remove the item.

There is no way I know of to remove items from an array programmatically, although you can change items. I suppose you could put a dummy value in to show nothing is there. Like Java, you can’t change the size of an existing array.

Hi,

We found an old post online explaining that items can't be removed from a list in Alice 3. Is that still the case? Should we keep on building new lists?

Best,
