Water Pea Care and Instructions

Please treat your water pea like a real pet fish. Feed daily!

 You will receive a single water pea egg. Drop the egg in the water and your baby pea will hatch. If your water pea is alive after 1 day, it will produce an egg that you can harvest.

Care and Instructions

Birth

When you place the water pea egg in water, it will take a few seconds for the egg to dissolve. Initially, the newborn water pea will be tiny and hard to see. Take care not to accidentally pick it up and drop it out of the tank.

 Water peas live for about 3 days if properly fed.

Feeding

Your water pea must be fed every day, or it will die. To be safe, feed it once in the morning and again at night.

 Water peas recycle vitamin B by producing caecal pellets. Wait for your water pea to produce the pellet and then collect it so you don't run out of food. This is their only source of nutrition!

 To collect the pellets, drag them to the top of the screen.
  • It's very hard to see baby pea pellets
  • Collect the pellets or you will quickly run out of food!

Habitat

Water peas live in water and surface periodically for oxygen. Without oxygen, a water pea will die within minutes. The longest a water pea has been observed to survive without oxygen is around 10 minutes. Yours probably won't last that long.

 You can help a baby water pea by moving it near the surface when you see it swimming up for air.

Disease

Water peas are highly susceptible to disease and aquatic illnesses. If your water pea gets sick, it needs to be dried out. Hold the pea outside of the tank until you see a message saying that the pea has been cured.

 When the pea is healthy, drop it back in the tank.

 Old food and waste can harbor parasites which can harm your water peas. Be on the look out for them.


Social

The most interesting thing about water peas is their social behavior. They sometimes appear to be aware of each other. Watch closely and you may see this yourself.

 Though they appear simple, the way that water peas move and interact is not predetermined, and appears to be random.

Reproduction

Reproduction is possible, but unlikely. Water peas become mature after a day or two, and produce a single egg. Reproduction requires a male and female.

 During reproduction, the female pea's egg will fall out and hatch a baby pea. You must harvest the egg from a male water pea, as it will never be used for reproduction.

Have Fun!

Take care of your water peas every day and make sure you harvest your daily egg. Once you stop taking care of them, your water peas will be gone for good.

Collisions with line intersections

Collisions can be determined by testing for line intersections. Imagine a line representing the ground and an object above, falling down. At time t1 , take the center point  p1  of the object. At time t2 , move the object down and take the center point p2 of the object. If the line formed by endpoints (p1, p2) intersect the ground line, a collision has occurred. On a collision, reset the object to its original position before the movement. When a collision occurs, be sure to reset the object by the same point used to determine the line intersection. In this example, I use the center point, so the object should be reset by the center point, not its actual x, y (usually top left) coordinate. It is not always the case that resetting by the x, y coordinate is sufficient. This can be seen in the following picture. It can be seen that even if the object isn't moving, but its size changes, a line intersection can occur, and resetting the object to its x, y position will...

Momentum transfer

This image shows different possible paths that result in a collision. Intuitively, we know which way the object should continue along the wall. Determining this mathematically is a bit more challenging. The object could go in one of two directions. That is, it could follow the wall one way or the other. But why should it prefer one direction over another? We need a generalized rule that applies for every wall and every angle of approach. The rule is that momentum is transferred along the path of least resistance . Least resistance is the difference between the wall angle and the angle of approach that is less than 90 degrees. This raises the issue that a line's angle is determined by its direction. This means that the end point we start with determines the angle of the line. See the line below. Is it a 45 degree line, or a 225 degree line? It depends on which point you start from. But, for a generalized rule of momentum transfer, the answer shouldn't matter. ...
