Unleashing the Power of Debugging Tools in Unreal Engine
Debugging has become an essential skill for game developers and technical artists working with Unreal Engine, particularly as the complexity of projects continues to grow. In a recent talk at Unreal Fest Bali 2025, Matt Ostel, a Senior Technical Artist at Epic Games, shared vital insights into advanced debugging techniques that can significantly streamline the development process. Here, we explore some of those insights and the notable tools available in Unreal Engine that can enhance productivity and effectiveness.
In 'Debugging Unreal Engine Projects: Lightning Round | Unreal Fest Bali 2025,' the discussion dives into essential debugging tools, exploring key insights that sparked deeper analysis on our end.
Breaking the Habit of 'Print String'
Many developers are guilty of relying too heavily on the 'print string' method for debugging, a common approach reminiscent of rapid debugging methods in scripting languages like Python. Ostel encourages moving beyond this simplistic approach by utilizing more appropriate tools built into Unreal Engine. For example, by using the newly introduced formatted text functionality, developers can craft messages that are dynamically updated without the clutter associated with traditional print outputs. This helps in maintaining a clean user interface while minimizing spam during testing.
Discovering Hidden Potential in Console Commands
Another essential highlight from Ostel's discussion was the myriad of console commands that enhance debugging capabilities. For instance, typing 'help' within the console not only filters the available commands but generates a locally searchable webpage that enhances usability. Moreover, commands like 'stat none' allow developers to streamline their output by removing clutter from their screens, enabling them to focus on what truly matters.
Game AI Debugging – A Step Forward
Debugging game Artificial Intelligence (AI) is another area where Ostel shared practical insights. Utilizing the gameplay debugger can provide developers with access to their AI behavior trees, EQS queries, and much more. This allows for a more comprehensive understanding of AI decisions and actions within the game, significantly reducing troubleshooting time and improving overall game quality.
Enhancing Audio and Animation Insights
Ostel also discussed innovative features for debugging audio in Unreal Engine. Developers are now equipped with tools that can isolate MetaSounds or visualize sound mixes, improving their ability to pinpoint audio issues in games. The new timeline scrubber available for animations takes debugging a step further, allowing developers to replay and sync animation states seamlessly, ensuring a smoother user experience.
Preparing for a Bright AI Future
The insights provided by Ostel serve as a reminder of the ever-evolving landscape of technology and the countless tools available to aid development. As women entrepreneurs and technology enthusiasts in Africa and beyond continue to navigate the sesational world of AI and game developments, understanding these tools can unlock new potentials in their projects and innovations.
