colonizer's Issues

Game Map Structure

Define a container structure for the game map. the structure i design should satisfied below need.

1. Have trigger system like Age of empire
2. Have heightmap and sea level definition
3. Have landmark (Player spawn place)
4. Support unit / building / env init placement
5. Can define items
6. Can import resources

Grid

The base of the map will use grid to store the data. so those information can be encode to an image
Such as terrain type, terrain height

Basic Mods Support System

This will become a long document as the time pass by...

Why

In order to enriching quality of the gameplay. easy to answer. but difficult to implement.

Concept

The game will have mods support. this includes new system, texture replace, model replace, script to run.
I decide to use moonsharp to support lua runtime machine in the project.

Fundation

In order to make most the game mod support. We need to think a system that can be dynamically change.

Property Part

The game object have property and dependent property, kinda like C# field and property. one is value that actually live in the object. another is calculate result. If every unit or building have this system. and the field and property store in a array. access them by key, it will become alot easy for mod to increase the number of property. you can do thing like create a entire new property and assign to unit and have system in the background checking it.

The calculate property will have Lua runtime attach a class object that access the source object's all property data. it sounds complicated. but it just means the calculate property can take other calculate property or field to calculate another result. this must be careful implement. And it should have loop prevent mechanism.

Mods Loading Flow

Extract all mods zip files from game folder to temp folder.
And load the manifest.json first to get the module info.

After all the mod is loaded
It will check the conflict and lack of dependent module. base on every module's manifest.

Mods Structure

Multiplayer System

I decide that i should use Mirror network plugin to save development time.
The game will contains host mode and server mode network structure.

Host mode can be done in the multiplayer mode
Server mode can be done by enter game with command argument

RTS Development Mechanic (Gameplay)

This will define how the gameplay works. detail explains the concepts.

Resources System

• Food
• Water
• Common Mineral
• Rare Mineral
• Gas
• Population

Resources Transportation

The road will be the import connection hub for the entire city you built.
The structure you build will provide a resources connection to each other.
For example the water generator station or powerplant can only supply the next block building
For the powerplant you can of couse build the Electric Tower for long distance traveling and it's cheaper than building entire road system for it.

Engineer

Can build everything. if precondition is satisfied such as tech is research.

The Base

Base will provide the food and water coverage
And you can spawn engineer here, as the time pass. the base upgrade will be popup one by one.
