Variables and lists

The Variables category (internally called "data") holds two kinds of storage: variables, which each hold one value, and lists, which hold many values in order. You create variables and lists with the "Make a Variable" and "Make a List" buttons at the top of the category; Bilup also has a dedicated variable manager for editing them in bulk.

A variable or list can be for all sprites (global) or for this sprite only (local to one sprite and its clones).

Variables​

  • variable (reporter) reports the variable's current value. Checking its box on the palette shows a monitor on the stage.
  • set variable to 0 stores a value.
  • change variable by 1 adds a number to a numeric variable.
  • show variable variable / hide variable variable shows or hides the stage monitor.

Lists​

  • list (reporter) reports the list's contents.
  • add thing to list appends an item to the end.
  • delete 1 of list removes an item by position (the menu also offers last and all).
  • delete all of list empties the list.
  • insert thing at 1 of list adds an item at a position, shifting the rest down.
  • replace item 1 of list with thing overwrites an item.
  • item 1 of list returns the item at a position.
  • item # of thing in list returns the position of an item, or 0 if not found.
  • length of list returns how many items the list holds.
  • list contains thing ? reports whether the list holds an item.
  • show list list / hide list list shows or hides the list monitor on the stage.

Bilup and TurboWarp extras​

  • list as JSON (data_listjson) reports the whole list as a JSON array string, useful for saving or sending list data as text.
