Title: Unity or Unreal Developer – Heavy Equipment Simulation (Crane Focus) Description: I’m looking for a developer to build a small, realistic prototype focused on crane operation. This is not a full game—this is a first-phase playable build that focuses on controls and physics. The goal is to create something that feels real, not arcade. --- Project Scope (Phase 1 – MVP): - 1 mobile crane (using pre-made asset is fine) - Basic crane controls: - Boom up/down - Extend/retract - Swing - Hoist up/down - Load system: - Attach/detach load - Weight affects crane behavior - Basic physics: - Load sway - Stability changes based on reach/weight - Simple tip-over or failure condition - Small environment: - Simple job site (construction-style area) - 2–4 basic lift scenarios (pick and place tasks) --- Important: This project is about gameplay feel and physics, NOT graphics or UI. --- Requirements: - Experience with Unity or Unreal Engine - Experience building gameplay systems (not just UI or menus) - Strong understanding of physics-based interactions - Ability to deliver playable builds during development --- Nice to Have (Not Required): - Experience with vehicle or equipment simulations - Knowledge of realistic physics tuning - Experience working with marketplace assets --- How I Want to Work: - Start with a small paid test task (crane movement + basic lifting) - Then continue into full MVP if it goes well - Payment will be milestone-based - I expect regular playable builds for testing --- Timeline: - MVP target: ~4–8 weeks --- Budget: - Open to proposals for MVP scope - Prefer fixed-price broken into milestones --- To Apply: Please include: 1. Examples of relevant work (especially gameplay or physics systems) 2. What engine you recommend (Unity or Unreal) and why 3. How you would approach crane physics in a simple but believable way --- Note: If you mainly do UI, menus, or basic apps, this is not the right project. I’m looking for someone who can make mechanics feel solid and realistic.

I have carefully reviewed your requirements and fully understand that this project is centered on realistic crane mechanics, physics accuracy, and gameplay feel, not visuals or UI. With 9+ years of experience in game development, I specialize in physics-driven systems, simulation-style gameplay, and responsive control mechanics. As a technical lead, I focus on delivering stable, testable builds with clean architecture and precise tuning. For this project, I recommend Unity due to its flexible physics control, faster iteration for prototyping, and strong support for custom simulation tuning. I will implement a modular crane system using rigidbody physics with constraints/joints, handling boom movement, extension, swing, and hoist with realistic weight influence, load sway, and stability logic. Tip-over conditions will be calculated based on center of mass, reach, and load distribution to ensure believable behavior. I will follow a milestone-based approach starting with your test task (crane movement + lifting), then expand into a full MVP including scenarios and environment. Regular playable builds will be delivered for validation and iteration. My experience includes developing gameplay systems where **mechanics feel responsive, grounded, and realistic, which aligns directly with your goal. Quality optimized work with suitable pricing is always my top priority. Come inbox & let’s get started. Best regards, Sohaib Pasn Games

Hi, I have strong experience in Unity and Unreal Engine, with a focus on building realistic gameplay systems and physics-based interactions. For this project, I’ll focus on building solid crane controls that feel natural, with realistic physics for load sway, crane stability, and failure conditions. I’ll ensure the crane behaves realistically based on weight and reach, using the engine’s physics system to tune behaviors accurately. I recommend using Unity for this project due to its ease of use and strong support for physics-based systems. I’ll deliver playable builds regularly for testing, starting with crane movement and basic lifting, progressing toward the full MVP. Best regards, Juan

With my diverse skill set and extensive experience in engineering and software development, I offer a unique advantage for your crane simulation project. While my core expertise lies in embedded systems, firmware development, and robotics control, your project primarily requires an understanding of physics-based interactions and the ability to create realistic gameplay systems. Having tackled complex tasks throughout my career, I am confident in my ability to create a robust prototype that closely emulates real-life crane operations. My working knowledge of both Unity and Unreal Engine equips me with the essential tools for this project. While both engines offer their own advantages, Unity’s flexible physics engine would be most suitable for your game feel focus. To approach crane physics in a simple yet believable way, I would leverage my experience with vehicle simulation projects. Rather than relying solely on marketplace assets, I believe in customizing every aspect wherever possible for optimal results. This includes tuning physics settings to ensure load sway, stability, reach-weight dynamics, and failure conditions are realistically represented.

Hello! I’m excited about your focus on creating a realistic crane simulation, and my background in physics-driven gameplay development aligns perfectly with what you’re building. I’ve worked extensively with both Unity and Unreal, especially on systems where weight, momentum, and mechanical behavior drive the feel of the experience. For your MVP, I can craft a believable crane control system with accurate sway, load interaction, and stability responses using proven physics methods. I’d approach this by tuning joint constraints, applying force-based behavior, and ensuring every movement feels grounded rather than arcade. I recommend Unreal for its robust physics pipeline, though Unity remains a strong choice depending on your long-term goals. Best regards!
