📱 POCKET CODE FNF ENGINE (The Ultimate Mobile Modding Tool)

Stop waiting for a PC to build your dream FNF mod. Create, code, test, and export your Friday Night Funkin' mods directly on your Android phone!

The Friday Night Funkin' modding scene has been heavily dominated by PC frameworks for years. Meanwhile, mobile creators were left with limited choices or terrible workarounds. Pocket Code FNF Engine is here to shatter that PC monopoly. Built entirely from scratch using accessible block coding logic, this engine transforms your smartphone into a fully functional game development studio.

⚡ THE POWER OF A VARIABLE-BASED ARCHITECTURE

Most mobile frameworks are rigid, hard-coded, and nearly impossible to modify without breaking things. This engine is completely different. It is engineered with a fully variable-based architecture. Every critical game state—from accuracy and health drain to note spawning and custom events—is controlled by dynamic variables.

🚀 Key Features for Developers:

👥 Insanely Fast Character Porting: No complex sprite sheet parsers or JSON headaches. Just drop your character's .png sheet into the project, insert a quick conditional check like if player1 == 'your_character', map the animations, and your character is ready to sing.

🛠️ Built-in Developer Tools: Check the internal tools/ folder. It is packed with pre-configured developer utilities and helper scripts designed to automate repetitive asset formatting and optimize your overall development workflow.

📊 Efficient Mobile Parsing: Engineered to handle and read step hits, BPM changes, and charts smoothly without choking your device's memory.

⚠️ CRITICAL DEVELOPER GUIDELINES (PLEASE READ)

To ensure your custom mods run flawlessly at stable frame rates and stay safe from plagiarism, you MUST follow these technical recommendations:

🚀 The Ultimate Runner (Use NewCatroid): Standard Pocket Code is not recommended for this engine. You should run your project using NewCatroid and make sure to enable the "Fast2D" rendering feature. This optimizes script and graphic processing, ensuring buttery-smooth 60 FPS gameplay even on budget or low-end mobile devices.

🔒 Protect Your Intellectual Property (.APK Export): When your mod is finished and you are ready to publish it online (on GameBanana, itch.io, Game Jolt, etc.), never share the raw project files. Always export your final build as a standalone .apk file. This locks your source code and prevents others from stealing your assets or messing with your scripts.

🛑 Hands Off the Core Logic! Do not tamper with the core engine code, especially the Chart Reading (Chart Parsing) mechanisms. These blocks handle the heavy mathematical synchronization between audio and video. Altering this logic will break the rhythm alignment and invite a nightmare of unfixable bugs.

📦 RECOMMENDED MOBILE TOOLCHAIN

Want to build a masterclass mod using only your phone? We highly suggest pairing this engine with this specific mobile developer stack:

🎨 Graphics & UI: Pocket Paint (Flawless transparency and layer handling right on your phone).

🎵 Audio & Vocals: FL Studio Mobile (Essential for multi-track sequencing, vocal tracking, and instrumental mixing).

📈 Chart Editing: Psych Engine Mobile (v0.7.1) (Use its perfect built-in mobile editor to design your charts, then easily extract the .json chart data and port it right into this engine!).

💬 COMMUNITY & SUPPORT
