Play without relying on one sense

Worked example

An incoming three-lane wave blocks left and center but leaves right clear. Randomly choosing among valid two-lane combinations creates variation while preserving an escape route. Scaffold C-PAUSE — Pause with an always-processing resume control Setup: Node2D World root has CanvasLayer HUD with Button Pause, plus normal gameplay children. Set Pause button Process > Mode to Always in Inspector; leave World and gameplay as Inherit/Pausable. Attach script to World; merge into its existing _ready if present. Signal callbacks still work from the always-processing button. Label text starts Pause. ```gdscript extends Node2D func _ready() -> void: $HUD/Pause.pressed.connect(_toggle_pause) func _toggle_pause() -> void: get_tree().paused = not get_tree().paused $HUD/Pause.text = "Resume" if get_tree().paused else "Pause" ```

Pause with an always-processing resume control

GDScript (Godot 4, not Scratch, Python, JavaScript or C#). Scaffold C-PAUSE. Copy starts from this text. The desk does not run it.

Scene and node setup

Node2D World root has CanvasLayer HUD with Button Pause, plus normal gameplay children. Set Pause button Process > Mode to Always in Inspector; leave World and gameplay as Inherit/Pausable. Attach script to World; merge into its existing _ready if present. Signal callbacks still work from the always-processing button. Label text starts Pause.

extends Node2D
func _ready() -> void:
    $HUD/Pause.pressed.connect(_toggle_pause)
func _toggle_pause() -> void:
    get_tree().paused = not get_tree().paused
    $HUD/Pause.text = "Resume" if get_tree().paused else "Pause"

Checks to run in the editor

• Paused gameplay stops, including timers.
• Same button remains responsive and resumes gameplay.

Native Godot 4.7.2.stable.official.ed1daf0bf headless compile and representative node-tree/runtime tests passed; see native-qa-results.json. Visual UI, audible output, exports and website submission still need separate checks.

Play without relying on one sense — evidence task

1. 1. Add pause/resume and visible control instructions.
2. 2. Test muted play, non-color recognition and keyboard navigation of buttons.

Deliverable. Accessible arcade checkpoint and three-condition checklist.

Acceptance checks

• VGC-L044-T1. Pause stops movement and spawning but Resume responds.
• VGC-L044-T2. Required information remains available with audio off.

Understanding question. Why does a paused game need an always-processing resume control?

Include a downloadable project ZIP with project.godot, .tscn, .gd and original asset files when code changes. A private, teacher-accessible download link to that ZIP is equivalent. Screenshots or a playthrough do not replace editable source.

If this is still shaky. Tune just hazard speed and spawn interval on a copied project. Use fixed test runs before adding more mechanics. Start with the first assigned task and re-run its acceptance test before adding the remaining feature.

Optional extra. Offer an optional challenge mode while retaining a gentle default. Document one changed parameter, your prediction, and the observed effect; optional, not required for completion.

Turn in typed notes and a JPEG, PNG, or WebP screenshot. One https address is stored as text and is not opened, extracted, or run. An MP3, WAV, M4A, MP4, or WebM file up to 4 MB can show a demo. The demo does not replace editable source. Zip and code files are refused. If there is no private link, keep the project on the family computer and review the code in person.
