Hello mentors ( Nikhil Ranjan Rajhans, Abha Kumari) ,
I have completed the entry task and made a fish with skeleton in blender and given it prodecural animations like swimming, fleeing , idling & Turning .I also added a few of my own to the code based on the actual projects requirement :
1) Animation based on environment ( Avoids terrain while swimming )
2) Animation based on behaviour (We can pick a target and the fish will swim to that target while avoiding the terrain and if there is a predator selected then the fish will run away from that predator till the distance between them is 50m).
