Pics

Les pics peuvent permettre d’apporter un peu de challenge pour le joueur, ou de contraindre sa circulation. Un pic bien placé peut à lui seul s’avérer un obstacle sérieux.

1. Charger une image

   load.js

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

2. Charger un son

   load.js

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

3. Déclarer un objet

   config.js

   const TILE_CONFIG = {
   
     "M": () => [ // pic à l'endroit
       sprite("spike"),
       area({ scale: vec2(0.6, 1) }),
       anchor("bot"),
       offscreen({ hide: true }),
       danger({ tag: "player" }),
     ],
   
     "W": () => [ // pic à l'envers
       sprite("spike"),
       pos(0, -64),
       area({ scale: vec2(0.6, 1) }),
       anchor("bot"),
       rotate(180),
       offscreen({ hide: true }),
       danger({ tag: "player" }),
     ],
   
     "S": () => [ // pic vers la droite
       sprite("spike"),
       pos(-32, -32),
       area({ scale: vec2(0.6, 1) }),
       anchor("bot"),
       rotate(90),
       offscreen({ hide: true }),
       danger({ tag: "player" }),
     ],
   
     "Z": () => [ // pic vers la gauche
       sprite("spike"),
       pos(32, -32),
       area({ scale: vec2(0.6, 1) }),
       anchor("bot"),
       rotate(270),
       offscreen({ hide: true }),
       danger({ tag: "player" }),
     ],
   
     "#": () => [ // 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('hurt', 'alive', (obj) => colorShiftFx(obj, { color: 'ff9b9b' }))
     on('hurt', 'alive', () => play('hit'))
     on('hurt', 'player', (obj) => obj.play('worry', { speed: 2, onEnd: () => obj.play('idle') }))
     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: `
   
              ===S M  M  M  M
                  === ==== ===
                      W  W      Z==
   
                      Z==S     Z==
               #  M M  ==  M M
             ===================
   
       `,
     },
   
   ]
