Mobile-optimized grid city builder with low-poly assets, efficient AI traffic, smart grid placement, and compressed save/load system for smooth performance and scalability.🏙️ Grid City Builder – Mobile-Optimized Unity TemplateBuild, expand, and simulate your own living city with a powerful, fully optimized grid-based city builder system designed specifically for mobile performance.This asset gives you everything you need to create a complete city-building experience, from intelligent placement systems to dynamic traffic simulation, all wrapped in a clean and scalable architecture.🚀 OverviewGrid City Builder is a complete Unity template built for developers who want to create mobile city-building games quickly and efficiently.With a strong focus on performance, scalability, and modular design, this system allows you to construct cities using roads, buildings, and zones while maintaining smooth gameplay even on low-end devices.It combines intuitive gameplay mechanics with advanced backend systems like optimized grid logic, AI traffic streaming, and compressed save/load systems.🧩 Core Features🏗️ Grid-Based Building SystemFully functional grid placement system with precise snappingSupports multiple building types:HousesRoads (with drag-based placement)Scalable buildings (variable sizes)Smart validation ensures:No overlapping objectsAccurate placement feedbackReal-time ghost preview system with valid/invalid indicators🏙️ Zoning SystemQuickly paint entire areas with zones:ResidentialCommercialIndustrialAutomatically populate zones with appropriate buildingsIdeal for rapid city expansion mechanics🚗 Advanced Traffic System (Highly Optimized)Fully grid-based traffic simulationCars follow structured paths and:Never overlapMaintain spacing intelligentlyIncludes:Road traffic (cars, vans)Water traffic (boats)Lightweight directional path system instead of heavy pathfindingDynamic spawning based on camera proximity for performance💾 Powerful Save & Load SystemComplete city persistence systemSaves:All buildingsRoadsLayoutsRotations and sizesUses optimized bit-packing compression for minimal storageInstantly reconstructs the entire city exactly as it was🔄 Demolishing SystemRemove any structure dynamicallyAutomatically frees grid spaceFully integrated with placement and save systems⚡ High Performance ArchitectureBuilt from the ground up for mobile:Uses Non-Alloc physics checks (no garbage memory)Array-based systems instead of dynamic listsEfficient grid occupancy trackingDistance-based AI spawning/destructionOptimized update cycles using coroutines🎮 Smooth & Modern UI System🎵 Centralized UI Audio (ButtonPlayer)One system controls all UI soundsNo need to assign audio per buttonClean hierarchy and lower memory usage🪟 UI
