Here is a condensed version designed to stay comfortably below 10,000 characters while preserving the important requirements. I am hiring an experienced Unreal Engine 5 C++ developer to build the gameplay and engineering foundation that will later integrate with a separate AI-assisted Schematic Software platform for my persistent MMO. This is a production-quality foundation, not a throwaway prototype. The purpose of this project is to build the weapon, ammunition, attachment, vehicle, physics/engineering, technology, material, and manufacturing-definition systems in a modular and data-driven way so that future player-created Schematics can configure them without requiring major redesign. The game uses Unreal Engine 5.7 for PC. CORE GOAL The future Schematic Software will allow players to design original weapons, ammunition, attachments, vehicles, and other objects. This project does NOT include building the full AI Schematic editor. Instead, it must build the Unreal gameplay foundation and standardized data interfaces that the future Schematic platform will use. Example: Schematic Definition → Weapon Definition → Unreal Runtime Weapon Schematic Definition → Vehicle Definition → Unreal Runtime Vehicle The developer should avoid building large numbers of hardcoded weapon or vehicle classes. The goal is a reusable system driven by structured definitions, reusable components, physical properties, materials, and capabilities. WEAPON SYSTEM The weapon framework should eventually support essentially every category, including: * Melee and primitive weapons * Bows/projectile weapons * Firearms * Explosives * Artillery * Missiles * Vehicle/aircraft/naval/spacecraft weapons * Energy weapons * Futuristic and fictional weapons The system should use reusable capabilities rather than completely separate architecture for every weapon. Possible configurable properties include: * Dimensions * Mass * Center of mass * Materials * Barrel/emitter properties * Ammunition * Projectile properties * Energy requirements * Rate of fire * Recoil * Heat * Accuracy * Range * Penetration * Durability * Structural properties * Handling * Attachment interfaces * Technology requirements Important performance values must be calculated or validated by trusted gameplay rules rather than accepted directly from player/client data. Players should not eventually be able to submit arbitrary values such as extremely high damage with zero recoil. Combat should be physically believable and cinematic where practical, including systems such as projectile travel, penetration, ricochets, recoil, heat, armor interaction, localized/component damage, and explosive effects. Random weapon jamming is not desired. AMMUNITION AND ATTACHMENTS Ammunition should exist as its own configurable definition and future Schematic type. Different ammunition designs should be capable of affecting weapon performance. Player-created attachments will generally be designed for specific weapon Schematics rather than being universal. Developer-created default weapons may use standardized attachment systems. Compatibility should be validated through data and relevant geometry/interface information. VEHICLE SYSTEM A reusable vehicle framework is required for future: * Wheeled vehicles * Tracked vehicles * Ground vehicles * Aircraft * Naval vehicles * Spacecraft * Futuristic vehicles This project does not require every final vehicle type to be finished. It should establish an extensible foundation and representative working examples. Possible vehicle properties include: * Dimensions * Mass * Center of mass * Materials * Structural properties * Propulsion * Energy/fuel * Steering/control * Suspension * Aerodynamics * Buoyancy * Armor * Damage * Weapon mounts * Cargo * Crew/passengers * Technology requirements PHYSICS / ENGINEERING FOUNDATION The game does not need professional engineering-software accuracy. The goal is believable and consistent game engineering. Examples: * Greater mass affects handling. * Material density affects weight. * Projectile mass and velocity affect impact. * Structural limits prevent obviously impossible designs. * Higher energy output may require greater heat management. * Powerful systems require appropriate physical volume, materials, energy, and technology. This foundation must support future validation of player-created Schematics. Players must not be able to exploit geometry or data to place impossible machinery, hidden functional systems, zero-volume components, unrealistic energy sources, or oversized systems inside tiny objects. TECHNOLOGY SYSTEM Current technology categories are: Primitive Medieval Victorian Industrial Millennium Advanced Technology Super Futuristic Super Futuristic technology is developer-restricted. Higher technology should primarily unlock better engineering capabilities, materials, precision, power density, efficiency, and manufacturing methods rather than simply applying percentage buffs. The architecture must allow additional technology classifications later. MATERIAL SYSTEM Gameplay material definitions should be separate from purely visual Unreal materials. Properties may include: * Density * Structural strength * Durability * Thermal properties * Technology requirements * Manufacturing difficulty New materials should be addable through data rather than major code changes. MANUFACTURING FOUNDATION The project should establish the data needed for future manufacturing. A Schematic should eventually be capable of producing requirements such as: * Required materials and quantities * Required technology * Machinery/facility requirements * Labor * Production time * Manufacturing difficulty * Quality/tolerance requirements The full animated manufacturing gameplay system does not necessarily need to be completed here, but the weapon and vehicle architecture must support it later without redesign. SCHEMATIC-READY DATA MODEL A major deliverable is the standardized interface between future Schematic Software and Unreal. The developer should propose appropriate production structures for areas such as: * Weapon Definition * Ammunition Definition * Attachment Definition * Vehicle Definition * Material Definition * Technology Definition * Manufacturing Definition * Performance/Simulation Definition * Schematic ID * Revision ID * Parent/Derivative Schematic ID * Validation Results The architecture should support versioning so future Schematic revisions do not break existing manufactured items or saved MMO data. SERVER AUTHORITY / SECURITY Important gameplay data must not be trusted from the client. The system must prevent manipulation of: * Damage * Weight * Range * Materials * Energy * Ammunition capacity * Manufacturing requirements * Technology requirements * Vehicle performance * Attachment compatibility * Other authoritative values These should be calculated, validated, or independently verified by trusted server/backend systems. MMO REQUIREMENTS The wider game is a persistent MMO using dedicated servers. The systems must therefore be compatible with: * Server-authoritative gameplay * Replication * Dedicated servers * Persistent item/Schematic identifiers * Future backend/database integration * Large numbers of player-created equipment definitions * Data-driven content rather than hardcoded assets This project does not include building the entire MMO backend, but clean backend integration interfaces are required. TEST IMPLEMENTATIONS I do not expect every weapon and vehicle in the game to be created during this project. The developer should build enough representative examples to prove the architecture, such as: * Configurable firearm * Ammunition * Melee weapon * Weapon attachment * Ground vehicle * Additional vehicle example proving extensibility * Material and technology definitions * Runtime spawning/configuration from structured data The developer may recommend a better test set. ARCHITECTURE REQUIREMENTS The system should be: * Unreal Engine 5.7 compatible * Primarily C++ * Modular * Data-driven * Extensible * Server-authoritative where appropriate * Suitable for long-term production * Compatible with Perforce * Documented * Designed for future Schematic, backend, faction, manufacturing, and AI integration Avoid unnecessary hardcoding and avoid tightly coupling weapon, vehicle, backend, manufacturing, and Schematic systems. EXPECTED DELIVERABLES * Technical architecture/specification * UE5.7 C++ source code * Weapon framework * Ammunition framework * Attachment framework * Vehicle foundation * Shared physics/engineering framework * Material system * Technology system * Manufacturing data foundation * Schematic-ready data interfaces * Server-authoritative validation foundation * Representative test implementations * Technical documentation * Repeatable/automated testing where appropriate PLEASE PROVIDE * Relevant Unreal Engine C++ experience * Weapon-system experience * Vehicle-system experience * Physics/simulation experience * Multiplayer/dedicated-server experience * Data-driven architecture experience * Examples of comparable work * Recommended architecture * Major technical risks * Proposed milestones * Estimated total hours * Estimated calendar duration The objective is to establish a production foundation that the future AI Schematic Software, manufacturing systems, backend, faction systems, and player-created content can use without requiring the weapon and vehicle architecture to be rebuilt later.

I can build this as a modular UE5.7 C++ foundation centered on versioned Weapon, Ammunition, Attachment, Vehicle, Material, Technology, Manufacturing, and Schematic definitions rather than hardcoded classes. Runtime instances will derive validated performance from trusted data, with server-authoritative checks for mass, dimensions, energy, damage, compatibility, technology, and manufacturing requirements. I’ll separate visual assets from gameplay materials, support stable IDs and revisions for persistent MMO data, and expose clean serialization interfaces for future Schematic and backend integration. The framework will be proven with configurable firearms, ammunition, melee weapons, attachments, ground vehicles, and extensible vehicle examples, including replication, dedicated-server compatibility, automated validation tests, documentation, and Perforce-friendly C++ organization.

Approach Weapon & ammo framework: Capability-based components (fire modes, projectiles, recoil, heat, penetration, durability) driven by structured definitions. No per-weapon hardcoding. Performance values calculated/validated server-side. Vehicle foundation: Extensible base with propulsion, mass/CoM, armor, mounts, and damage. One ground + one additional type (aircraft or tracked) as proof. Shared engineering layer: Materials, technology tiers, structural limits, energy/heat, manufacturing data. Geometry + data validation to block impossible designs. Schematic-ready interfaces: Versioned definitions (Weapon/Ammo/Attachment/Vehicle/Material/Technology/Manufacturing) with IDs, revision tracking, and clean backend hooks. Server authority: All critical values (damage, weight, range, capacity, compatibility) calculated or verified on dedicated server. Client data never trusted. Test set: Configurable firearm + ammo + melee + attachment + ground vehicle + second vehicle type + materials/tech definitions + runtime spawn from data. Everything stays modular, Perforce-friendly, and ready for the future AI schematic platform, manufacturing, and MMO backend. Relevant experience

The hard part here isn't modeling weapons or vehicles - it's making sure every object in the MMO comes from **validated data** rather than hand‑crafted classes. If that pipeline isn't solid, the future AI Schematic editor will constantly hit engine limits and the server won't be able to enforce authoritative physics or engineering rules. I've built modular, capability‑based systems where runtime objects are assembled from definitions instead of deep inheritance. For this project, I'd structure weapons, ammo, attachments and vehicles around shared C++ components: physical properties, propulsion, energy systems, structural limits, projectile behavior, and manufacturing metadata. Server‑side rules would compute mass, recoil, penetration, heat and compatibility so players can't inject impossible values. I'd start by defining the Schematic‑Ready data model: IDs, revisions, material definitions, technology tiers, geometry constraints and validation steps. Then build representative examples (firearm + ammo, melee, attachment, ground vehicle) to prove extensibility. One early risk is geometry exploits - zero‑volume components, hidden oversized systems, unrealistic energy sources - so engineering constraints must be part of the core. A few questions: 1. Should validation run fully server‑side or partially client‑side for immediate feedback? 2. Do you already have a preferred data format for Schematic definitions? Happy to outline milestones and estimated hours. Juan Pablo

Hi, I’ve carefully reviewed your requirements. The main focus should be a modular, data-driven foundation that allows future Schematic definitions to configure weapons, vehicles and other systems without rebuilding the core architecture. I can structure the UE5.7 C++ framework around reusable components and versioned data definitions for Weapons, Ammunition, Attachments, Vehicles, Materials, Technology and Manufacturing. My approach would cover: • Modular UE5.7 C++ architecture • Data-driven weapon and vehicle systems • Shared physics/engineering validation • Material and technology definitions • Server-authoritative validation of critical values • Versioned Schematic/Revision IDs • Dedicated-server and replication support • Clean interfaces for future backend/Schematic integration • Representative test implementations • Documentation and automated testing where appropriate I would begin with the architecture and data contracts, then implement representative firearm, ammunition, attachment, melee and vehicle examples to prove the framework is extensible. Key technical concerns I’d address early are client-side manipulation, persistence, validation of impossible designs, replication performance and compatibility between Schematic revisions. I’m ready to start with the architecture milestone and provide regular source updates and documented progress.

Consider this ✔️The key here is creating a modular system driven by structured definitions, ensuring the gameplay foundation supports future player-created Schematics without major redesign. A common issue is maintaining performance values that are calculated by trusted gameplay rules rather than accepted directly from player/client data. I understand the importance of building a reusable weapon and vehicle framework that allows for diverse player-created content. What usually matters most here is ensuring compatibility through data and geometry validation, preventing exploitation of unrealistic systems. Your need for a robust weapon system, extensible vehicle framework, and a solid physics foundation is clear, ensuring future scalability. With years of experience in Unreal Engine 5, I've helped bring complex, data-driven systems to life. You can expect a stable architecture, low risk of future redesign, and streamlined integration with backend systems. If you want, I could take a look at your existing files and give you some direction? Best, Kurt.

I've built data-driven systems for multiplayer games where the architecture had to survive player-created content without redesign, which is exactly what you're doing here with Schematics. The non-obvious part is that you're not building a content editor—you're building the foundation that a future AI tool will *use*, which means every weapon and vehicle framework needs to support validation and server authority from day one, not bolted on later. I'd start by mapping out the Schematic-ready data interfaces first, then build the weapon and vehicle frameworks around those contracts. That way everything stays loosely coupled and the backend integration becomes straightforward. I've done similar work on faction-based progression systems and physics-backed gear that needed to prevent client-side exploits. Worth a conversation to talk through the architecture approach and break down the milestones. Corné

Hello, Major risk is coupling gameplay logic to ephemeral data formats from the AI-assisted Schematic Software, which will block extensibility and server-authoritative validation. I propose a strict separation: canonical runtime C++ structs and a lightweight import layer that maps external schematics into validated, versioned data assets consumed by Unreal Engine 5.7 servers. I have 12+ years building game-grade systems in Unreal with C++, including modular weapon frameworks (melee, hitscan, projectile, ballistic), vehicle systems (wheeled, tracked, VTOL prototypes), and deterministic physics simulation layers tuned for multiplayer. I built server-authoritative replication and rollback for a PvP title and authored data-driven manufacturing pipelines that allowed designers to add materials and part classifications without engine changes. I can provide code samples and engine excerpts on request. I will begin by defining the core data model: classifications, material table, schematic import contract, and server validation rules. First step is a small prototype that demonstrates a weapon category, one ammunition type, and a manufacturing recipe round-trip from schematic import to replicated gameplay effect. Recommended architecture: Unreal Engine 5.7 C++ modules for GameplayFramework, DataImport, PhysicsSim, and ServerAuthority with JSON/YAML import adapters and UDataAssets for runtime. Major technical risks: divergent schematic schema changes, floating point nondeterminism across dedicated servers, and latency-sensitive vehicle physics on authoritative servers. Mitigations: versioned import adapters, fixed timestep deterministic substepping, and authoritative interpolation with server-side correction. Estimated total hours: 600-900 hours depending on depth of simulation. Estimated calendar duration: 4-6 months with a 2-person core team. - Do you have an initial schematic schema or sample files to validate the import contract? - Which dedicated-server hosting and authoritative rollback requirements must I target first? Thank you, Christopher
