Consistent Game Content Creation via Function Calling for Large Language Models

Tools for designing content require a medium that allows the designer to efficiently express their creativity, and a system that ensures the content being designed adheres to the domain of interest. Interacting with Large Language Models (LLMs) via natural language is extremely intuitive for a human designer, although it remains largely unexplored. However, this approach has a limitation: LLMs are prone to hallucinations and they tend to ignore parts of the user request in their responses. One workaround is to let LLM use tools such as function calling to ensure consistency of the content. We formalise this approach by proposing LLMaker, a general framework for consistent video game content generation empowered by LLMs, bridging the gap between creative vision and technical execution. We demonstrate LLMaker’s application in generating dungeon crawler level layouts, comparing it against alternative LLM-based methods for content generation over multiple tests, testing for consistency of the outputs and elapsed time per request.
