Goal: To get multiple game objects to act as sea snake or tentacle segments without using Unity physics and use little CPU.
Technique: Each segment's transform is updated using LookAt and translation.
Only the red cube is AI controlled. The rest of the segments play follow the leader.
AI managed game objects showing their states. Red for avoid.
These multi-segment fish use simple physics and use less CPU.
These nettles are procedural and use simple physics.
