Les objets rebondissants peuvent être l’occasion de confronter le joueur à de nouveaux challenges sollicitant sa précision et son sens du timing

1. Charger une image

   load.js

   const PNG = [
     "mushroom",
     "grass",
   ]

2. Charger un son

   load.js

   const MP3 = [
     "boing",
     "wooosh",
     "off",
   ]

3. Déclarer un objet

   config.js

   const TILE_CONFIG = {
   
     "C": () => [ // champignon
       sprite("mushroom"),
       area(),
       anchor("bot"),
       body({ isStatic: true }),
       offscreen({ hide: true }),
       scale(),
       spring(),
     ],
   
     "#": () => [ // player 1
       sprite("bean"),
       platformerController(),
       jumpController(),
       sleep(),
       alive(),
       opacity(),
       scale(),
       health(1, 4),
       area(),
       body(),
       respawn(),
       falling(),
       rotate(),
       pos(0, -20),
       anchor("center"),
     ],
   
     "=": () => [ // block
       sprite("grass"),
       area({ collisionIgnore: ["agent"] }),
       body({ isStatic: true }),
       anchor("bot"),
       offscreen({ hide: true }),
       tile({ isObstacle: true }),
     ],
   
   }

4. Lancer une animation

   game.js

   scene("game", () => {
   
     const tiles = { ...TILE_CONFIG, ...LEVELS[CURRENT_LEVEL].tiles }
     const config = { ...LEVEL_CONFIG, ...LEVELS[CURRENT_LEVEL].config, ...{tiles:tiles}}
     const map = LEVELS[CURRENT_LEVEL].map.split('\n')
     const level = addLevel(map, config)
     const utility = add([
       multiplayerCamera(),
     ])
     setGravity(config.gravity)
     setBackground(config.backgroundColor)
   
     on('spring', 'spring', (obj) => squishFx(obj))
     on('spring', 'spring', () => play('boing'))
     on('jump', 'player', () => play('wooosh'))
     on('drop', 'player', () => play('off'))
     on('respawn', 'player', (obj) => obj.play('idle'))
     on('sleep', 'player', (obj) => obj.play('sleep'))
     on('awake', 'player', (obj) => obj.play('idle'))
     on('jump', 'player', (obj) => obj.play('jump', { speed: 4, onEnd: () => obj.play('idle') }))
     on('drop', 'player', (obj) => obj.play('worry'))
   
   }

5. Placer les objets

   level.js

   const LEVELS = [
   
     {
       map: `
   
             ===       === ===
   
   
                   C      C
   
                               ===
   
             #    C       C
           =====      C
   
       `,
     },
   
   ]
