A few weeks ago, Jack from Branta Games presented a captivating video that showcased a distinctive effect. In this video, objects animated on a randomly generated field of black-and-white pixels become visible only when they are in motion. Although the concept isn't entirely novel, as Jack was inspired by Chris Long's recent videos on this particular phenomenon in computers from the 1980s, the developer took it to the next level by experimenting with different versions and eventually transforming it into an additive cyclic noise shader for Godot.

Unlock the Mysterious World of Persistence of Vision in Gaming

Application in Horror Games

Jack realized that this persistence of vision effect is an ideal fit for a horror game, more like a "Nobody will believe you" game. In such a game, you are constantly on the edge, as you can never capture a clear picture of your enemies. It adds an extra layer of suspense and mystery, making the gaming experience truly immersive. The randomness of the black-and-white pixel field and the visibility of objects only when they move create a sense of unease and unpredictability that is perfect for horror games.

Imagine being in a dark and eerie environment, with enemies lurking in the shadows. The only way to detect them is when they move, and even then, it's a fleeting moment. This adds a whole new dimension to the horror genre, as players have to rely on their instincts and quick reflexes to survive. It's a unique and thrilling concept that sets this horror game apart from others.

Another Use Case

Another use case that immediately comes to mind is in educational games. The persistence of vision effect can be used to teach concepts such as motion, perception, and visual stimuli. By presenting objects in a random field of pixels and showing how they become visible only when they move, students can gain a better understanding of these concepts in a fun and engaging way. It makes learning more interactive and memorable, as opposed to traditional lecture-based methods.

For example, in a science game, students can explore how different objects move and interact with each other on the pixel field. They can observe how the visibility of objects changes as they move and use this knowledge to solve puzzles or complete tasks. This hands-on approach to learning can enhance students' understanding and retention of the material, making it a valuable tool in the educational setting.
