In the 14th puzzle, we implemented a firefly flying through the maze with scripting, but we also tried it with a particle system.
Adjusted the size, occurrence frequency, speed, movement and fluctuation of light emission so that it behaves like a firefly. Add more lighting and check it on the actual machine. Compared to our own implementation, we can increase the number of lights without restrictions, so we adopt this implementation.
We will consider using our own creations for NPCs walking around the museum.
