also animals who have a jump lover then 1 or 2 blocks jump can't swim eaither.This will mostly apply wargs,ponies,etc. Also Rhinos and Giraffes shouldn't be able to swim since they are very heavy.

This should make the mod little bit more realistic Why can't Trolls swim?

They might be heavy, but they can't drown from their own weight, if anything, they should be very, very fast swimmers.

EDIT: I see the problem, you don't understand bouyancy.

Ponies, Horses, Rhinos and Giraffes are all very able to swim, and Wargs would probably be able to as well.

In fact, horses (and most other mounts) have the ability to carry a rider on their back while swimming. It doesn't have to do with the weight, it has to do with the weight:area ratio.

For example, the reason trolls would be able to swim is because, since their insides are hollow AND they have a large surface area, they would probably be able to swim normally. This is because the surface area splits up all the weight onto different parts of the body, and the normal force (force that stops you from falling through the floor or sinking) and because of the size of their arms, they would be rather fast similair to whales. One big sweep and they are proppeled forwards due to having more force then mass.

However, like you said, Gondorian Soldiers would probably not be able to swim because of the armor being heavy, and since it fits closely around their body, it doesn't add any surface area to make up for it, and so all the weight is pushed down in one area, and they sink to the bottom of the ocean.

Here's an experiment to prove how Trolls would be able to be bouyant in water:

Get a wide piece of wood (representing a troll), and a small piece of wood (a gondor levymen) and drop them both in water. See which one sinks.

They both should stay afloat, because the weight of the large piece of wood is being spread out into all the surface area, and so the pressure of weight is split up.

Then, take a rock (representing a armored gondorian solder) the same size as the small piece of wood, and drop that in the water.

What should happen is the rock would sink, because the surface area of the stone is small, but it is extremely dense, and so all the weight is being pushed into 1 spot.

I agree heavily armored soldiers technically shouldn't be able to swim, but that would make combat extremely annoying until armor weights are added. While yours is a good explanation you may be forgetting that trolls are supposed to be made of stone!
