Design - Horizontal Grammar

[thisandagain]

To Do

• Define subset of blocks for initial design pass
• Initial design pass
  • Flag
  • Event receipt
  • Event emitter
  • Move right [int]
  • Reset
  • Say [string]
  • Repeat [int]
  • Forever
• Design review
• Second design pass
• Handoff for implementation

Questions

• Should the "forever" block continue to be an end-cap? No (see below)
• Should we have a template for a block w/o an icon (text-based)?
• How do we handle use-cases like the "Mic" block in Scratch Jr?

Note: Meeting tomorrow to define block subset for initial design review.

[thisandagain]

Initial set of block "primitives" defined. Couple questions regarding iterators / "C" blocks, but otherwise moving forward as planned.

[thisandagain]

Follow-up from design meeting yesterday:
Yes, we will drop the "end cap" style block and migrate the "forever" iterator to follow the "repeat" block's implementation. This should help smooth the transition between the horizontal and vertical grammars.

Round 1.1 — Horizontal Blocks

Larger notches

Round 1.2 — Horizontal Blocks

Smaller notches

Blocks are sketched on a 4px grid. These PNGs are exported at 2x for HI-DPI screens. Colors are still a WIP.

Round 4 – Horizontal Blocks

• Larger Notches
• Smaller 40px icons
• 4px border-radius
• Rounded Event Cap / Forever Loop

Still Needs work

• Icons
• Colors

Standard Block - Reset

Standard Block with Int Input - Move Up

Standard Block with String Input - Say

Event Cap - Green Flag

Event Cap with Dropdown Input - Broadcast Message

Control Loop with Int Input - Repeat

Control Loop - Forever

Primitives have been defined and broken out into their own issues as listed above.
