I’ve been trying to locate information on pathfinding for AI objects inside a volume (freely move in both the X and Y axes) but am not seeing any information to steer me in the right direction. Most of what I’ve found relates to NavMeshes placed on a surface.
I’m trying to create an underwater environment with AI controlled fish, that can move freely in the volume occupied by the space between the ocean floor and the water surface; the depth of this volume can vary at certain points. Is there a best practice for implementing such a movement behavior? I’m not concerned about obstructions at this time…just moving to predefined locations within this volume and also wandering at varying depths/following bottom contour.
