   ]

5. Lancer une animation

   game.js

   function events() {
     return {
       add() {
         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') }))
   
         // personnages
         on('respawn', 'alive', (obj) => (obj.flipY = false));
         on('hurt', 'alive', (obj) => {
           play('hit');
           colorShiftFx(obj, { color: 'ff9b9b' });
         });
         on('death', 'alive', (obj) => {
           obj.flipY = true;
           wait(0.2, () => {
             if (!obj.isAlive) {
               obj.hidden = true;
               obj.collisionIgnore = ['*'];
               obj.isStatic = true;
             }
           });
         });
   
         // joueur
         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) => {
           play('wooosh');
           obj.play('jump', {
             speed: 4,
             onEnd: () => obj.play('idle'),
           });
         });
         on('drop', 'player', (obj) => {
           play('off');
           obj.play('worry');
         });
         on('hurt', 'player', (obj) => {
           obj.play('worry', {
             speed: 2,
             onEnd: () => obj.play('idle'),
           });
