Walkthrough

Adds a complete 3D gem-tilt game with scene setup, WASD controls, physics, win and loss handling, gallery registration, and English and Spanish translations.

Changes

Gem Tilt Game

Layer / File(s)	Summary
Scene and gameplay setup examples/gem_tilt_game.flock	Configures the sky, lighting, camera, instructions, floor boxes, physics-enabled ball, textured gem, scene objects, and UI text variables.
Controls and animated floor examples/gem_tilt_game.flock	Maps WASD actions to floor rotation and enables animated physics for the assembled floor.
Game state and gallery registration examples/gem_tilt_game.flock, main/examples.js, locale/en.js, locale/es.js	Displays loss and win messages, hides the gem after contact, registers the example in the games gallery, and adds English and Spanish labels.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to da42e

The PR adds a playable gem-tilt example, but the current scene setup may allow the ball to escape through the four walls, making the demo fail during play. This concrete correctness issue should be fixed or explicitly accepted before merging.

824-875: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Verify the tilt step and the tilt axes.

Each handler rotates floor by 1 degree. If when_action_event with pressed fires once per key press, the player needs many presses to tilt the floor enough to move the ball. Confirm the event repeats while the key is held, or increase the step.

Also confirm the axis choice. floor is already set to x = 90 at lines 1117-1152. LEFT and RIGHT then rotate around Y, so the two tilt directions may not stay perpendicular in world space.

Run the following script to check the event repeat semantics and the rotation axis convention:

#!/bin/bash
# Description: Inspect when_action_event 'pressed' repeat behaviour and rotate_model_xyz axis handling.
set -euo pipefail

fd -t f -e js -e ts | xargs rg -n -C 10 'when_action_event' | head -n 120
fd -t f -e js -e ts | xargs rg -n -C 10 'rotate\b.*addRotation|rotateModelXYZ|rotate_model_xyz' | head -n 120

when_action_event handlers for pressed actions to ensure held keys repeat often
enough to produce the intended floor tilt; if they fire only once, increase the
rotation step or use the established repeat behavior. Confirm rotate_model_xyz
axis semantics against floor’s initial x rotation, and update the LEFT, RIGHT,
and related handlers so their world-space tilt directions remain perpendicular.

- Around line 337-410: Add STATIC physics bodies for all four wall boxes, box1
through box4, so each wall mesh is included in collision detection;
alternatively, update the existing add_physics setup to create one compound
shape containing the floor and child wall meshes. Preserve the current floor
physics while ensuring the ball cannot escape the play area.
