Life-Simulator

A program that simulates life in a defined area. It is written in Java and uses JavaFX for its GUI. You can download and run the "Life Simulator.jar" file if you want to try it out.

Simulator Rules

• Simulation starts with a number of creatures and food spawned in.
• Food spawns every second and does not expire till eaten.
• Creatures lose energy when moving. Amount depends on the size, sight, and speed of the creature.
• Creatures die when their energy reaches 0.
• Creatures cannot move outside the defined area.
• Creatures obtain energy from eating food/prey.
• Creatures 1.2 times larger than another will consider it as food/prey.
• Creatures move randomly until food/prey enters their sight radius which they will move towards it.
• Creatures will move away from predators within their sight radius. Takes priority over food.
• Creatures whose energy reaches the replication threshold will spawn another creature and lose half their energy.
• Newly spawned creatures have the same properties as their parent but has a chance of one property being modified.
• Creatures spawn with a set amount of energy. Amount is half the replication threshold.

Simulation Settings

Entities

• Food energy: Amount of energy provided when eaten.
• Prey energy: Amount of energy provided when eaten.
• Replication threshold: Amount of energy needed to spawn a creature.

Environment

• Area width: Width of the simulation area.
• Area height: Height of the simulation area.
• Food spawn rate: Amount of food spawned per second.
• Mutation chance: Percent chance of a mutation occuring when spawning a creature.

Initial Values

• Creature count: Number of creatures spawned at the start of a simulation.
• Food count: Number of food spawned at the start of a simulation.
• Size: Starting size of creatures.
• Speed: Starting speed of creatures.
• Sight: Starting sight of creatures.

Mutations

• Speed: When enabled, creatures now have a chance of spawing with speed modified.
• Size: When enabled, creatures now have a chance of spawing with size modified.
• Sight: When enabled, creatures now have a chance of spawing with sight modified.

Note: This program has no scientific backing. It was made for fun and learning/practicing programming.
