Developer Uses Claude AI for C++ Game Development in Unreal Engine

A developer on r/ClaudeAI shared their experience using Claude AI for game development in Unreal Engine with C++. After switching from Gemini, which "shat the bed after 1 week," they used the lowest paid tier of Claude with Opus extended for planning and Sonnet for implementation.

Project Details

The developer is working on their second game, a cyberpunk city-builder using fully procedural generation, all coded in C++ through the web interface. Their first game was built entirely with Unreal Engine blueprints since they couldn't code in C++ previously.

Workflow and Results

They report making "months of progress in just weeks" using Claude. Specific implementation details include:

• Replacing Epic's Fab Marketplace assets with Claude-generated code
• Building an AI traffic controller with distance-based ticking
• Implementing frustum culling (removing what you can't see)

The developer notes they were able to do this for free through Claude, raising concerns about the future of game asset sales.

Usage Patterns

Initially, they frequently exhausted daily and weekly limits. Now with Claude Projects and starting new chat windows for every new topic (even small ones), they haven't reached limits with the 4.6 models. They also mention Claude occasionally acknowledges its ignorance and warns not to trust it.

Important Context

The developer emphasizes they're a "vibe coder" with 2 years of Unreal Engine blueprints experience, which provided the fundamental knowledge needed to architect projects, manage development, and provide accurate feedback to Claude. They note this approach isn't suitable for complete beginners without UE experience.
