আসসালামু আলাইকুম টেকবাসী। আজকের পোস্টে আমি দেখাবো কীভাবে খুব সহজেই এইচটিএমএল, সিএসএস এবং জাভাস্ক্রীপ্ট ব্যবহার করে কীভাবে একটি নরমাল এবং সুন্দর একটি রেসিং গেইম বানানো যায়। ইন্টারেস্টিং লাগছে? আপনার কৌতুহল দমন করতে এই পোস্টটি পড়ুন! এবং

দেখুন, কীভাবে কোনো প্রোগ্রামিং দক্ষতা ছাড়াই আপনি একটি গেইম তৈরী করতে পারবেন।

কমবেশি সবাই নিজেদের একটা গেইম বানাতে চান, কিন্তু ভালো মানের গেইম বানানো ব্যয়বহুল এবং গেইম বানাতে প্রচুর প্রোগ্রামিং দক্ষতা এবং আরো অনেক বিষয়ে জ্ঞান থাকতে হয়। তাই কীভাবে আপনি সহজেই একটা গেমের মালিক হতে পারেন, তা আমি আজ আপনাদের দেখাবো। তাহলে শুরু করা যাক।

#০২ ⇒ এবার এই কোডগুলো একটি .html ফাইলে পেস্ট করে সেভ করুন। চাইলে .html ফাইলটি ওয়েব সার্ভারে আপলোড করতে পারেন।

নিচে কিছু ডেমো ফটো দিলাম দেখুনঃ

অনেক সহজ ছিলো তাই না? গেইমটি খেলে দেখুন, কেমন লাগে। যদিও এটি হাই লেভেল গেইমের মতো ফিল দেবে না। তবুও আপনার তৈরী প্রথম গেইম হিসেবে ভালোই বলা চলে। গেইমটি যখন আপনার বন্ধুরা খেলবে আর আপনাকে বাহবা দেবে, তখন কেমন ফিল হবে বুঝতে পারছেন? আপনি ভাবতে থাকুন, আমি পোস্টটা শেষ করছি। খোদা হাফেয।

HTML / CSS দিয়ে তৈরী করুন অসাধারণ কার রেসিং গেইম !!
