# Project Towny Mechanics System - Design Doc

*For Project Towny Update 0.7 (Research Update), Version 1.0*
*Currently in early planning stages, nothing seen below is final!*

## Basic Mechanics
In the tech tree there are two paths to go down, basic circuitry and basic mechanics. You have to pick both to reach the end but you can pick which one you focus on first.
The idea behind circuits is the only way to produce them is in large multiblocks in large volumes, while mechanical parts are created by hand in smaller volumes.

## Mechanical Parts
Mechanical Parts fall into 3 categories, mass produced parts, advanced parts, and hand made parts. Mass produced parts can be made with machines in bulk. Advanced parts are made out of mass produced parts. Hand made parts are made by hand in a 5x5 crafting table (giving us 25 slots to work with).

Below are some examples of each:
#### Mass Produced Parts
- [x] Gears
- [ ] Belts
- [ ] Screws?
- [ ] Rotors

#### Advanced Parts
- [x] Electric Motors
- [x] Mechanical Components

#### Hand Made Parts
* Engines
* Rocket Parts
* Pollution Scrubber (Item that goes in the infinte filter)

## Gear Tiers
Gears are sorted into tiers based on when they are unlocked and how difficult they are to produce:

| Gear Material | Tier | Tech |
| -------- | -------- | ----- |
| Wooden | 1 | Basic Engineering
| Stone | 2 | Basic Engineering
| Iron | 3 | Electricity
| Steel | 4 | Replaceable Parts
| Platinum | 5 | Space Exploration
