R12.10.01.03-T01 Make a Scratch sprite move forever and bounce off edges

原始指令

In Scratch 3 (desktop app), open fixtures/bounce_start.sb3 (one Cat sprite, no scripts). Build a script: when green flag clicked → point in direction 45 → forever { move 5 steps; if on edge, bounce }. Set rotation style to left-right. Save as bounce.sb3.

建议验证方式

Headless scratch-vm runs bounce.sb3 for 600 frames: sprite x/y must oscillate within stage bounds and hit ≥ 2 edges; rotation style left-right. The instrumented editor logs block drag/drop events; a project.json written outside the editor (no matching drop events) scores 0.

建议部分得分

30% green-flag forever loop; 40% bouncing verified in VM; 30% rotation style and direction

R12.10.01.03-T02 Debug a Scratch game whose score never increases

原始指令

fixtures/apple_catch.sb3 is a catch game: a Bowl sprite follows the mouse and Apple clones fall. The 'score' never increases when an apple touches the bowl. Find and fix the bug in the blocks (do not rewrite the game), keep all other behaviour, and save as apple_catch_fixed.sb3.

建议验证方式

VM test injects mouse positions so 3 apples land on the bowl: score must equal 3, and misses must not change it. Block diff vs original must be ≤ 4 blocks changed (minimal fix). Editor drop events logged; external project.json edits fail.

建议部分得分

60% score increments once per catch; 20% misses do not score; 20% minimal block diff

R12.10.01.03-T03 Switch costume and play a sound on the space key in Scratch

原始指令

In fixtures/dancer.sb3 (sprite 'Dancer' with 4 costumes), add a script so pressing space switches to the next costume and plays sound 'Pop' until done; pressing 'r' resets to costume 1. Save as dancer_keys.sb3.

建议验证方式

VM test: 5 simulated space presses cycle the costume index 1→2→3→4→1→2 and trigger 'Pop' each time; 'r' sets costume 1. Editor drop events must account for all new blocks.

建议部分得分

50% costume cycling; 25% sound on each press; 25% reset key

R12.10.01.03-T04 Compute 1 + 2 + … + 100 with a Scratch loop

原始指令

Create a new Scratch project with variables 'i' and 'sum'. When the green flag is clicked, set sum to 0 and i to 1, repeat until i > 100 { change sum by i; change i by 1 }, then make the sprite say sum for 2 seconds. Save as sum100.sb3. This is the GUI half of the pair with T19.

建议验证方式

Blockly Games stores the solved level and program XML in localStorage; grader reads it: level 6 marked complete, block count ≤ 7, and re-running the XML in a headless maze runner reaches the goal. Workspace changes must come from drag events (Blockly change listener log), and DevTools are disabled by browser policy, so localStorage cannot be written by script.

建议部分得分

60% level completed; 40% block count ≤ 7

R12.10.01.03-T06 Draw a target pattern with Blockly Games Turtle

原始指令

In Blockly Games Turtle level 8 (locally hosted), the goal image shows a pattern of three overlapping stars. Build a block program with loops (not repeated copies) that draws the pattern so the canvas matches the goal, and submit it.

建议验证方式

Turtle level reports success (pixel match against the goal canvas within the game's tolerance) and the program XML contains at least one repeat block with ≤ 12 blocks total. Solved flag and XML read from localStorage. DevTools are disabled by browser policy, and a solved flag without matching Blockly drag events in the change-listener log scores 0.

建议部分得分

60% canvas match/level success; 40% loop-based program within block limit

R12.10.01.03-T07 Build a recursive factorial custom block in Snap!

原始指令

In Snap! (locally hosted), create a custom reporter block 'factorial (n)' in the Operators category that uses recursion (if n ≤ 1 report 1 else report n × factorial(n − 1)). Use it in a script that says factorial(10) when the green flag is clicked. Export the project as factorial.xml.

建议验证方式

Exported XML parsed: custom block definition in Operators, type reporter, body calls itself; headless Snap! evaluation gives factorial(10) = 3628800 and factorial(0) = 1. The block editor is the only route (no text import of block definitions allowed, import events logged).

建议部分得分

30% custom reporter defined; 40% recursive body correct; 30% green-flag script outputs 3628800

R12.10.01.03-T08 Filter and transform a list with Snap! higher-order blocks

原始指令

In Snap!, open fixtures/scores.xml with list variable 'scores' (30 numbers). Using 'keep items' and 'map' (no loops), build a script that sets variable 'passed' to the scores ≥ 60, each converted to a letter grade (A ≥ 90, B ≥ 80, C ≥ 70, D ≥ 60). Export as scores_hof.xml.

40% keep filter correct; 40% map to letters correct; 20% no explicit loops

R12.10.01.03-T09 Build a complete Pong game in Scratch from an empty project

原始指令

Create Pong in Scratch: a paddle that follows the mouse x at the bottom, a ball that bounces off walls and the paddle with a random angle change of ±15°, a 'score' variable that increases on each paddle hit, a 'misses' counter, and a game-over backdrop with all scripts stopped after 5 misses. Save as pong.sb3.

建议验证方式

VM test suite (12 tests) drives mouse x: paddle tracks mouse; ball reflects at walls; paddle hits raise score; 5 misses switch backdrop and stop scripts. Editor drop-event log must cover the blocks; projects assembled outside the editor fail.

建议部分得分

15% paddle; 25% ball physics; 20% scoring; 40% miss counter and game-over state

R12.10.01.03-T10 Program a micro:bit dice in MakeCode and test in the simulator

原始指令

In the MakeCode for micro:bit editor (offline app), build blocks so that on shake the LED shows a random number 1-6 as a dot pattern of the die face, and on A+B it shows the temperature. Test both in the built-in simulator, then download the .hex to ~/Downloads/dice.hex.

建议验证方式

Embedded project source in the .hex is extracted; a headless pxt simulator test fires shake 100 times: LED patterns must be the 6 die faces only with each value seen; A+B shows the temperature string. JavaScript-view edits are logged and disallowed, and the instrumented editor logs block drops; a .hex whose blocks lack matching drop events scores 0.

建议部分得分

50% shake shows valid die faces; 20% all six values reachable; 30% A+B temperature

R12.10.01.03-T11 Make a MakeCode Arcade collector game with score and timer

原始指令

In MakeCode Arcade (local web build), create a game: a player sprite moves with the D-pad (speed 100), 5 food sprites spawn at random positions, overlapping food adds 1 point and respawns it, and a 30-second countdown ends the game. Use the sprite editor to draw a 16×16 player in at least 3 colours. Export the project.
