Wa-tor is a computer program that simulates an ecosystem of creatures living in an underwater world. Think of it like a virtual ocean, where different animals live, eat, and reproduce.
In this virtual world, there are two types of creatures: fish and sharks. The fish are orange, and the sharks are gray.
The fish swim around the ocean, looking for food. They can only move in four directions: up, down, left, or right. They can only move one square at a time, and they can't move through walls.
The sharks also swim around looking for food, but they eat the fish. The sharks are faster than the fish and can move two squares at a time.
As time goes by, the fish will eat seaweed to stay alive, and the sharks will eat fish to survive. The fish can reproduce, and they will do so if they find a mate and if there is enough seaweed nearby.
As for the sharks, they will also reproduce if they find a mate, but only if they have eaten enough fish. If the sharks don't eat enough fish, they will starve to death.
The wa-tor program has different modes where you can adjust how many fish and sharks there are, how fast they move, and how many squares are in the ocean. You can also turn on a visualization mode that shows you what's happening in the virtual ocean in real-time.
Overall, wa-tor is a fun and educational way to learn about ecosystems and how different animals interact with each other in a virtual world.
