# Genome and player
This document describes principles I have came up with. I don't think I'd be angry if you use them in your projects.
This document is mostly for me to remember things.
## Used terms
MC - Modification Currency. Currency that player spends on modifications
## The core principles are:
- Every plant that is represented as graph can be drawn.
- Player should have all necessary instruments to create anything he likes by the end of his playthrough.
- Player's tools should progress through game
## Progression
- Player should start small
- Player starts with somewhat of a currency to spend on modifications each level
- Player starts with allelic crossingover and "combine" tools
- Progressing through the levels, player gains the most important instruments
- Optional instruments and template plants are bought through shop
## Levels
- Before level, player may adjust his plants collection through experimentation.
## Planned tools
Early game:
- Allelic crossingover
- Player picks two plants, and they exchange genes that are on the same places.
- As an output, player gets two plants.
- Upgrades to "Swap places" tool
- Costs 1 MC
- Categoric crossingover
- Player picks two plants, and they exchange genes that hold the same label.
- As an output, player gets two plants.
- Upgrades to "Swap" tool
- Costs 1 MC
- Combine tool
- Player picks donor and recipient plant. Then, algorithm decides whether to replace one node or to add as a child. Then, algorithm picks subgraph from donor, and applies it to recipient.
- As an output, player gets two plants - recipient and donor.
- Upgrades to "Add" tool
- Costs 1 MC
- Random deletion tool
- Player picks one plant, and algorithm randomly deletes genes from it.
- As an output, player gets one plant.
- Upgrades to "Remove" tool
- Costs 1 MC
- Random mutation tool
- Player picks one plant. Then, algorithm mutates it randomly and uncontrollably.
- As an output, player gets one plant.
- Upgrades to "Batch mutation" tool.
- Costs 1 MC
Midgame
- Remove tool
- Player picks one plant. They might pick one or more nodes to delete. Then, selected genes are deleted.
- As an output, player gets one plant.
- Costs 1.5 MC
- Add tool
- Player picks donor and recipient plant. Then, player selects one or more genes. Then, player selects to replace or position subgraph.
- As an output, player gets two plants - recipient and donor.
- Costs 2 MC
- Upgrades to "Create" tool
- Swap tool
- Player picks two plants. They must pick first and second genes.
- As an output, player gets two plants with swapped genes.
- Costs 0.25 MC
- The cost is low because it was meant to be applied multiple times
- Swap places tool
- Player picks two plants. Then, player selects one or more genes that will be swapped.
- As an output, Player gets two plants with swapped genes.
- Costs 1.5 MC
- Batch mutation tool
- Player picks one plant. Then, player selects amount of mutations.
- As an output, Player gets one plant.
- Upgrades to "Batch controlled mutation" tool
- Costs 3 MC
- Batch controlled mutation tool
- Player picks one plant. Then, Player selects genes to mutate.
- As an output, player gets one plant.
- Costs 5 MC
Endgame
- Create tool
- Player has genes dock. Player constructs tree from them, and then attaches it to selected plant, or creates new.
- As an output, player gets one plant.
- Costs 10 MC
