Design and implementation of a simulation of a fictitious world called “Planisuss”, inspired by Wa-Tor and Conway’s Game of Life.
- requirements.txt file for pip
- requirements.yml file for anaconda
Run the planisuss_main.py file in python
python your-path/planisuss_main.py
For modifying all the constants present in the simulation just edit the file planisuss_constants.py. Here we can find all the lower and upper bounds for the values of the stats of Erbast and Carviz, constants for the initialization of the code like the number of rows and columns of the grid, and other ones used for the decision function presents in the code.
key_press_event interactivity with the simulation (keyboard):
- “escape”: close the simulation;
- “spacebar”: play/pause the simulation;
- “r”: visualize only the Carviz on the grid;
- “g”: visualize only the Erbast on the grid;
- “b”: visualize only the Vegetob on the grid;
- “a”: visualize the complete grid;
- “u”: update manually to the next day (only while pause is True).
button_press_event interactivity with the simulation (mouse):
- “click” in the plot in which is visualized the world (the grid): select the cell in which zooming in and the cell chosen to be analysed in the table. You can click either in the complete grid, or in the zoomed one.
The Planisuss world is constituted of a single continent which is populated by three species: Vegetob, Erbast, and Carviz. In the simulation, several individuals of the species interact evolving their population.
Planisuss is regularly structured in geographical units called cells. Cells are organized in a regular grid structure. The cells can be occupied by water or ground. Each ground cell can host individuals of the three species, while water cells are uninhabitable. All the Erbast in a cell constitute a herd. Similarly, all the Carviz in a cell constitute a pride. The basic events on Planisuss happen in discrete time units called days.
Three species populates Planisuss:
- Vegetob is a vegetable species. Spontaneously grows on the ground with a regular cycle. Vegetob is the nutrient of Erbast. The density can have a value between 0 and 100.
- Erbast is a herbivore species. Erbast eat Vegetob. They can move on the continent to find better living conditions. Individuals can group together, forming a herd.
- Carviz is a carnivore species. Carviz predate Erbast. They can move on the continent to find better living conditions. Individuals can group together, forming a pride.
Erbast and Carviz are animal species, and are characterized by the following properties:
- Energy: represents the strength of the individual. It is consumed for the activities (movement and fight) and can be increased by grazing.
- Lifetime: duration of the life of the Erbast expressed in days.
- Age: number of days from birth. When the age reaches the lifetime values, the individual terminates its existence.
- Social attitude: measures the likelihood of an individual to join to a herd.
The time on Planisussis structured in units called day. A day is articulated in the following phases:
- Growing: Vegetob grow everywhere of a fixed quantity.
- Movement: The individuals of animal species (Erbast and Carviz) decide if move in another area. Movement is articulated as individual and social group (herd or pride) movement.
- Grazing: Erbast which did not move, can graze the Vegetob in the area.
- Struggle: Carviz insisting on the same area can fight or hunt.
- Spawning: Individuals of animal species can generate their offspring.
