Zombies

Zombies is a JALSE example project. Is is a small simulation in which a healthy person or people can be "infected." Infected people chase and "bite" healthy people, until the entire population is infected (and eventually dies).

Building and running with Gradle

1. Build using ./gradlew build (see Building Java Projects with Gradle)
2. Run using ./gradle run (See The Application Plugin)

Simulation details

1. Initially, 100 Healthy people (white circles) are spawned and wander randomly about the screen.
2. To start a simulation, click a person. That person becomes Infected (red circle).
3. Infected people move 1.5x faster than Healthy ones, but Healthy people see 1.5x as far. Healthy people always move away from the nearest visible Infected (or randomly if no Infected people are visible), and Infected always move toward the nearest Healthy person.
4. When an Infected person touches a Healthy one, the Healthy person is bitten and becomes a Carrier. Carriers move randomly and are ignored by both Healthy and Infected people as they transition from Healthy to Infected.
5. If an Infected person does not bite a Healthy person within 10 seconds, they starve to death and become a Corpse (gray circle). This timer resets every time they bite a Healthy person.
6. Eventually, all Infected will die off; usually, at this point, all that remain are Corpses.

Controls

Various properties of the simulation can be adjusted using the sliders on the right. All changes take place immediately, but you can click Reset Simulation if you'd like to start a new simulation with your selected settings.

• Population: The total number of people in the field.
• Infected Relative Speed (%): The speed of Infected, as a percentage of the speed of Healthy people.
• Healthy Sight Range: How far Healthy people can see, in pixels.
• Infected Sight Range: How far Infected people can see, in pixels.
• Infection Time (s.): How long it takes a person to transition from Healthy to Infected. Nominally in seconds, but may be longer depending on performance.
• Starvation Time (s.): How long it an Infected person can go between bites without starving.
