Raw
This is an ambitious architectural project. You aren't just building a game; you are building a **cross-platform layout engine** based on a custom logic language.
To make this work, you need to separate the **Logic (The Graph)** from the **Representation (The Scene Tree)** and the **Implementation (The Platform).**
Here is a breakdown of how to approach this architecture:
### 1. The App Graph DSL (The "Source of Truth")
Your DSL should not describe *where* a card is on screen, but *what* the card is and *how it relates* to others. Since you mentioned a requirements graph, your DSL is essentially defining a **Directed Acyclic Graph (DAG)** or a General Graph.
**Suggested DSL Structure:**
Instead of writing raw code, think of your DSL in terms of:
* **Nodes:** The entities (Company, Employee, Department, Tech Stack).
* **Edges:** The requirements/dependencies (Employee > needs > Desk).
* **Attributes:** Metadata (Cost, Efficiency, Risk level).
**Example Conceptual Syntax:**
```hcl
node "Server_Rack" {
type = "infrastructure"
cost = 500
}
node "Junior_Dev" {
type = "talent"
requires = [Server_Rack] // This creates the graph edge
}
connection "Junior_Dev" -> "Server_Rack" {
relationship = "depends_on"
}
```
### 2. The Translation Pipeline (The Transpiler)
You need a middleware layer that converts your Graph DSL into a **Scene Tree**. A scene tree is hierarchical, whereas a graph is networked.
**The Process:**
1. **Parser:** Reads the DSL > creates an **Abstract Syntax Tree (AST)**.
2. **Graph Resolver:** Analyzes dependencies and "complications." It determines the state of the game logic.
3. **Scene Tree Mapper:** This is the critical part. It maps graph nodes to visual objects.
* *Example:* A "Node" in the graph becomes a "Card UI Component" in the scene tree.
* *Example:* An "Edge" (requirement) becomes a "Connecting Line" or a "Status Icon" on the card.
### 3. Target Implementations
Since you want this to work in Godot and the Web, you should implement a **Platform Adapter Pattern**.
* **Godot Adapter:** Translates the Scene Tree into `Node2D` or `Control` nodes. It uses Godot's internal tree for rendering and input handling.
* **Web Adapter:** Translates the Scene Tree into HTML/CSS (DOM) or a Canvas-based system (like React Flow or PixiJS).
### 4. Handling "Complications" in the Graph
Since your game revolves around complications, the graph isn't just for layout—it's the **game engine**.
* **Validation Pass:** Every time a user stacks a card (adds a node), the engine runs a validation pass across the requirements graph.
* **Propagation:** If a "Power Outage" complication node is added to the graph, it propagates down all edges to any "Server" nodes, marking them as `inactive`.
* **Visual Feedback:** The Scene Tree reflects this state change (e.g., the card in Godot turns red or shakes).
### Summary of the Technical Stack
| Layer | Technology/Concept | Responsibility |
| :--- | :--- | :--- |
| **Language** | Custom DSL > JSON/YAML | Defining entities and requirements. |
| **Logic** | Graph Theory (DAG) | Calculating dependencies and complications. |
| **Intermediate** | Scene Tree IR | Converting networks into hierarchies. |
| **Frontend A** | Godot (GDScript/C#) | High-performance game rendering. |
| **Frontend B** | Web (TS/React/Vue) | Accessibility and browser distribution. |
### The "Killer Feature" Opportunity
By building the DSL first, you've essentially created a **Modding Tool**. Anyone can write a text file in your DSL to create new "Company Packs" or "Complication Sets," and those files will work identically across both Godot and the Web without you having to rewrite any game logic.
