🎮 How to Use

In-Game Testing:

  1. Open Browser Console (F12)

  2. Access Systems:

    const visualCues = game.scene.scenes[1].visualSoundCues;
const inputSystem = game.scene.scenes[1].inputRemapping;

  3. Test Subtitles:

    // Change size
visualCues.setSubtitleSize('large');

// Show subtitle with speaker
visualCues.showSubtitle('Hello!', 3000, 'NPC', 'left');

// Adjust opacity
visualCues.setSubtitleOpacity(0.5);

  4. Test Input Remapping:

    // Switch profile
inputSystem.switchProfile('left-handed');

// Rebind action
inputSystem.startRebinding('interact', (action, key) => {
    console.log(`Rebound ${action} to ${key}`);
});

// Check binding
console.log(inputSystem.getBindingDisplay('move_up'));

  5. Run Automated Tests:

    • Copy content of test_accessibility.js
    • Paste into console
    • Watch 40-second automated test
