使用html+javascript實(shí)現(xiàn)金幣落袋效果實(shí)例代碼

 更新時(shí)間:2026年06月04日 10:12:44   作者:蠟臺(tái)  
想在自己的網(wǎng)站首頁搞點(diǎn)喜慶的氣氛,在網(wǎng)上找素材無意中發(fā)現(xiàn)有一個(gè)掉金幣的JS特效,感覺挺好玩的,也是我想要找的效果,這篇文章主要介紹了使用html+javascript實(shí)現(xiàn)金幣落袋效果的相關(guān)資料,需要的朋友可以參考下

如圖:

金幣飛入頂部金幣欄的動(dòng)效,支持多金幣同時(shí)飛、帶拋物線 + 3D 旋轉(zhuǎn) + 落地反饋

要讓金幣落袋效果更逼真,我們可以從物理軌跡(拋物線 / 貝塞爾曲線)、細(xì)節(jié)反饋、音效與特效、性能優(yōu)化這幾個(gè)維度入手,把 “簡單的直線飛” 升級成 “像游戲里一樣的真實(shí)感動(dòng)畫”

  • 拋物線軌跡:金幣飛出時(shí)先向上 “拋” 一下,再落向目標(biāo),模擬重力和初速度。
  • 隨機(jī)偏移:每個(gè)金幣的起點(diǎn) / 落點(diǎn)有微小偏差,避免 “復(fù)制粘貼式” 的僵硬感。
  • 初速度與加速度:前半段快,后半段減速,模擬空氣阻力。
  • 3D 旋轉(zhuǎn) + 透視:金幣在飛行中繞不同軸旋轉(zhuǎn),配合大小變化模擬近大遠(yuǎn)小。
  • 光影變化:飛行時(shí)的亮度 / 透明度隨角度變化,模擬光照。
  • 尾跡 / 拖影:短暫的淡金色尾跡,強(qiáng)化速度感。
  • 落地反饋:金幣到達(dá)目標(biāo)時(shí),錢袋 / 數(shù)字有輕微的 “抖動(dòng) + 放大” 效果,增強(qiáng)交互反饋。

音效與震動(dòng)

  • 金幣飛行的 “咻” 聲、落地的 “叮” 聲。
  • 移動(dòng)端可以加輕微震動(dòng),強(qiáng)化 “落袋成功” 的爽感。

性能與體驗(yàn)

  • 金幣復(fù)用池:避免頻繁創(chuàng)建 / 銷毀 DOM,提升流暢度。
  • 限制最大同時(shí)動(dòng)畫數(shù)量,防止卡頓。
  • 響應(yīng)式適配,不同屏幕下軌跡不跑偏。

</html>

尾跡 / 拖影效果

在金幣飛行路徑上生成短暫的淡金色小圓點(diǎn),模擬速度感:

// 在animate函數(shù)里添加
if (progress < 0.9) {
    const trail = document.createElement('div');
    trail.style.cssText = `
        position: fixed;
        left: ${x-6}px;
        top: ${y-6}px;
        width: 12px;
        height: 12px;
        border-radius: 50%;
        background: rgba(255,223,79,0.6);
        pointer-events: none;
        opacity: 0.6;
        z-index: 998;
    `;
    document.body.appendChild(trail);
    // 尾跡逐漸消失
    setTimeout(() => trail.remove(), 100);
}

音效反饋

添加金幣飛行和落地的音效,這里用 Web Audio API 簡單實(shí)現(xiàn):

// 初始化音頻上下文
const audioCtx = new (window.AudioContext || window.webkitAudioContext)();

// 飛行音效(高音調(diào))
function playFlySound() {
    const oscillator = audioCtx.createOscillator();
    const gainNode = audioCtx.createGain();
    oscillator.connect(gainNode);
    gainNode.connect(audioCtx.destination);
    oscillator.frequency.value = 800;
    oscillator.type = 'sine';
    gainNode.gain.setValueAtTime(0.1, audioCtx.currentTime);
    gainNode.gain.exponentialRampToValueAtTime(0.001, audioCtx.currentTime + 0.1);
    oscillator.start(audioCtx.currentTime);
    oscillator.stop(audioCtx.currentTime + 0.1);
}

// 落地音效(清脆的叮聲)
function playLandSound() {
    const oscillator = audioCtx.createOscillator();
    const gainNode = audioCtx.createGain();
    oscillator.connect(gainNode);
    gainNode.connect(audioCtx.destination);
    oscillator.frequency.value = 1200;
    oscillator.type = 'sine';
    gainNode.gain.setValueAtTime(0.2, audioCtx.currentTime);
    gainNode.gain.exponentialRampToValueAtTime(0.001, audioCtx.currentTime + 0.15);
    oscillator.start(audioCtx.currentTime);
    oscillator.stop(audioCtx.currentTime + 0.15);
}

// 在createFlyingCoin里調(diào)用飛行音效,在動(dòng)畫結(jié)束時(shí)調(diào)用落地音效

另一種效果如圖:

先上代碼

        * {

            padding: 0;
            box-sizing: border-box;
        }
        body {
            height: 100vh;
            background: #0b1020;
            overflow: hidden;
            user-select: none;
        }
        /* 錢袋 */
        .bag {
            position: fixed;
            bottom: 60px;
            left: 50%;
            transform: translateX(-50%);
            font-size: 120px;
            z-index: 10;
        }
        /* 金幣 */
        .coin {
            position: fixed;
            width: 32px;
            height: 32px;
            border-radius: 50%;
            background: radial-gradient(circle, #ffdf4f, #ffb700);
            box-shadow: 0 0 12px #ffd000;
            pointer-events: none;
            transition: all 0.8s cubic-bezier(0.15, 0.6, 0.3, 1);
        }
    </style>
</head>
<body>
    <div class="bag">??</div>

    <script>
        const bag = document.querySelector('.bag');
        let bagRect;

        // 更新錢袋位置
        function setBagPos() {
            bagRect = bag.getBoundingClientRect();
        }
        window.addEventListener('load', setBagPos);
        window.addEventListener('resize', setBagPos);

        // 點(diǎn)擊生成金幣
        document.addEventListener('click', e => {
            createCoin(e.clientX, e.clientY);
        });

        function createCoin(x, y) {
            const coin = document.createElement('div');
            coin.className = 'coin';
            coin.style.left = x - 16 + 'px';
            coin.style.top = y - 16 + 'px';
            document.body.appendChild(coin);

            // 目標(biāo):錢袋中心
            const targetX = bagRect.left + bagRect.width / 2 - 16;
            const targetY = bagRect.top + bagRect.height / 2 - 16;

            requestAnimationFrame(() => {
                coin.style.left = targetX + 'px';
                coin.style.top = targetY + 'px';
                coin.style.transform = 'rotate(1080deg) scale(0.1)';
                coin.style.opacity = 0;
            });

            // 銷毀節(jié)點(diǎn)
            setTimeout(() => coin.remove(), 800);
        }
    </script>
</body>
</html>

自定義參數(shù)調(diào)整效果代碼

/* 金幣大小 */
width: 30px; height: 30px; 

/* 動(dòng)畫時(shí)長(越快數(shù)值越?。?*/
transition: all 0.6s; 

/* 錢袋大小 */
font-size: 100px; 

/* 金幣顏色(金色系可修改) */
background: radial-gradient(circle, #ffd700 0%, #ffcc00 50%, #e6b800 100%);

連續(xù)點(diǎn)擊批量生成金幣,可修改代碼:

// 點(diǎn)擊生成5個(gè)隨機(jī)金幣
document.addEventListener('click', (e) => {
    for(let i=0; i<5; i++){
        // 隨機(jī)偏移位置
        const offsetX = (Math.random() - 0.5) * 50;
        const offsetY = (Math.random() - 0.5) * 50;
        createCoin(e.clientX + offsetX, e.clientY + offsetY);
    }
});
