In the 14th puzzle, we made the maze look like a forest, so we added lights like fireflies that flutter around in the maze.
For the behavior of the light, we first considered NavMeshAgent, which is a function of Unity, but the preparation (collider and baking work) was difficult.
So we created a simple script to hang around the prefabs. The script wobbles randomly through the registered points, sometimes going backwards and passing through.
However, since it is a prefab with a built-in spotlight, it is not possible to generate many due to the limit on the number of lights.
Particle systems are also considered.
