fishtank sim

Unity version: 2020.3.26f1

Environment

Tank Assumptions: Consistent ambient temperature cycle, Consistent water level, Consistent filter maintinence, 75 liters of water.

Nitrogen Cycle

Carbon Cycle

• Fish (- oxygen, + co2)
• Plants (+ oxygen, - co2)

Bacterial Cycle

Nutrient Cycle

General Plans

• Should fish have happiness?
• Come up with a SOLID system for units of measurement.
• Should fish be able to reproduce?
• System for plants growing dynamically? (simple random patterns?)

Fish Size (Sprite Size)

Three fish sizes small, medium, and large.

Three stages baby, juvenile, adult.

• small / baby : 32x32 sprite

• small / juvenile : 48x48 sprite

• small / adult : 64x64 sprite

• medium / baby : 64x64 sprite

• medium / juvenile : 80x80 sprite

• medium / adult : 96x96 sprite

• large / baby : 96x96 sprite

• large / juvenile : 128x128 sprite

• large / adult : 160x160 sprite

Animation plans

One script for each type of movement that can be easily reused with a few ambiguous variables like speed.

• Schooling fish (swim with others of same size class)
• Territorial Fish (avoid others of same size class or larger)
• Benthic fish (sticks to the bottom mostly)
• Snail (slow edge bound movement)
• Water Bug (irratic movement)

Design Plans

• Each Fish is an entity
• Each plant is an entity
• Simulation consists of updating a series of environment parameters each step based on all the other entities
• Control light
• Control tank flow (filter bandwidth)
• Control filter medium (Carbon filter)
• Control temperature
