Bilup extras

Bilup is built on TurboWarp, which is built on Scratch. Along the way both projects added blocks that stock Scratch does not have. This page collects those extra blocks in one place. Each one lives in its normal category and is also linked from that category's page. For extension blocks (Pen, Music, and so on) see Extensions instead; this page is only the built-in extras.

Some of these blocks are shown in the palette by default; others are compatibility or advanced blocks that come from imported projects or from turning on the right addon. They all run the same way in the compiler and interpreter.

Motion​

  • point towards x: 0 y: 0 faces a specific coordinate instead of a menu target.
  • point towards x: 0 y: 0 from x: 0 y: 0 faces from one coordinate toward another.

See Motion blocks.

Control​

  • while <condition> loops while a boolean stays true (the inverse of repeat until).
  • for each item in 10 loops a set number of times, setting a variable to 1, 2, 3, and so on.
  • all at once runs its wrapped blocks in a single frame with no screen-refresh yielding. Kept for compatibility with older projects; ordinary scripts under warp behave the same.
  • switch expression / case value / default / break build a switch statement. switch picks a branch by matching value; a plain case runs its branch and stops; default runs when nothing matches; break and case fall-through control let one case continue into the next.
  • counter (reporter), increment counter, set counter to 0 are a simple built-in counter carried over from Scratch 2, so you can count without making a variable.

See Control blocks.

Operators​

  • letters 1 to 3 of apple returns a substring between two positions.
  • item in apple returns the position of a substring (case-insensitive), or 0 if not found.
  • replace a with - in apple replaces every occurrence of a substring (case-insensitive).
  • ab repeated 3 times repeats a string.
  • upper / lower case of Apple changes the case of text.
  • trim apple removes surrounding whitespace.
  • clamp 5 between 0 and 10 limits a number to a range.
  • min / max return the smaller or larger of their operands.
  • pi reports 3.14159...
  • newline reports a line-break character.

See Operators blocks.

Sensing​

  • online? reports whether the device has a network connection (navigator.onLine).
  • stage width / stage height report the stage size in pixels.

See Sensing blocks.

Variables and data​

  • list as JSON reports a list as a JSON array string.

See Variables and lists.

My Blocks​

  • return value ends a custom block and hands a value back to the caller, letting a custom block act as a reporter.
  • is compiled? / is bilup? are special boolean argument-reporter names: is compiled? reports true when the compiler is running, is bilup? always reports true here.
