Memorias Ao Mar DevBlog & Release

The Game:

Memórias ao Mar is a story-driven sailing game, where you battle against winds and uses old locating methods.

You'll have to use landmarks in your environment as references to locate and guide yourself to solve what happened to your distant relatives.

 

The game is only available in Brazilian Portuguese, and we have no plans to translate it.

The Story:

After forty years away, Kai returns to his home island, upon arriving, realizes that things are no longer as they used to be. Now, he is forced to investigate to understand what really happened.

Devlog:

The game started out as an ocean simulation, I was trying to simulate buoyancy on water, and experimented with moving objects on top of the water surface. Buoyancy force is calculated by the depth that each node is in multiplied by the buoyancy value, that way we can have complex shapes simulating buoyancy defined by their outlines and mass.

 

 

Next, I experimented with adding wind forces, which are basic boxes that apply a force to the object inside it.

 

Next it was time to add waves, I needed to create a custom shader that would offset the plane's vertices by the wave height at that location. Also, the buoyancy mechanic now gets its water height from the OceanManager script that controls both the shader and water height.

Now I wanted to test sailing, for this the craft calculates the velocity to be applied forward by multiplying the base velocity by how perpendicular are the sails to the wind. Don't worry, the current wind implementation is much more involved and actually calculates drift and drag, so you also need to keep in mind the angle of approach.

I won't bore you with every detail, but this is the basics of the game and if you'd like to learn more about it go download and play it on itch.io, or message me via email or any other means you'd like.
