Spatial / Grid
Grid
Grid systems organize space into orthogonal cells that support discrete simulation, pathfinding, line-of-sight rules, and compact tactical reasoning.

Program And Scale
Browse this topic by program branch and operating scale.
This topic now keeps program branches and scale lanes visible inside the module, so local reading paths can stay aligned with the same branch-and-scale language used elsewhere.
Spatial Structures
Explain how topology, region graphs, corridors, map abstraction, and scale determine movement and leverage.
Start in Spatial, reduce the map into region graph and corridor logic, test topology under disruption, then return through a spatial design guide.
Cross-Scale · 1Local Scale · 1Network Scale · 1
World Foundations
Explain what the world is materially built from before politics, balance, or style are discussed.
Start in Worlds, read the anchor framework, open one regional model, validate with a complete study, then finish with a world assembly guide pass.
Regional Scale · 2
Flow and Logistics
Explain how resources, goods, labor, information, and force circulate, stall, buffer, and break.
Start from the resource-flow loop, trace storage and throughput models, compare one logistics study, then run a flow audit worksheet.
Network Scale · 1
Show scale lanes
Regional Scale
Use this scale when the region is the main leverage unit for settlement, extraction, governance, or conflict.
Network Scale
Use this scale when routes, relays, buffers, and linked nodes matter more than territorial bulk.
Cross-Scale
Use this scale when the strongest explanation depends on several levels staying visible together.
Local Scale
Use this scale when precise local occupancy, blocking, or interaction geometry is the right lens.
What It Governs
This topic gives the module a usable operational frame.
Grid logic matters when the design benefits from orthogonal movement, exact occupancy, and explicit local constraints.
Orthogonal Constraint
The grid privileges horizontal and vertical relations, which can be a feature rather than a flaw.
Tile Semantics
Each cell can encode occupancy, cover, visibility, cost, and simulation state with high precision.
Path Clarity
Grids make local path and blocking logic explicit, especially in built environments.
Scale Fit
Grid systems work best when the space being modeled already behaves as rooms, streets, lanes, or discrete parcels.

Reading Stage
Stage 1: Find the underlying adjacency structure

Grounding Route
Ground grid logic in occupation and route control.
Use grid logic when local blockage and exact occupancy matter, but keep the abstraction tied to real street, room, corridor, or defense structure.
Choose the local scale the grid is actually representing.
Return to geography when the grid is hiding the real route and terrain logic that should shape a district, fortress, or street network.
Use route and reach vocabulary instead of tile-only language.
The grid should still express controlled lanes, defended approaches, and exposed edges rather than anonymous cells.
Connect the grid to force projection and denial.
Open combat systems when the grid's real job is to make occupation, blocking, and approach windows legible.

Design Checklist
Use these prompts to keep the page actionable.
Open this when you want to pressure-test the topic instead of browsing for orientation.
Open the topic checklist
- What does one tile represent in-world?
- Why is orthogonal movement useful for this problem?
- How do diagonals, cover, and chokepoints behave inside the lattice?
- Check whether tile scale matches the intended tactical decisions.
- Make blocking and line-of-sight rules consistent with movement rules.
- Test whether local geometry creates interesting constraints or just clutter.
- Using a grid where the world really needs corridor or graph logic.
- Tile detail so fine that pathfinding overwhelms strategy.
- Orthogonal restrictions that feel arbitrary because the environment does not support them.
Cross-model Handoff
Move from local grids to broader spatial frames
Grid is strongest when it is paired with a clear larger-scale abstraction.
Alternative lattice
Hex
Compare to hex when range and territory matter more than orthogonal occupation.
Simulation scopeAOI
Open AOI when the real challenge is simulation density and attention management.
Tactical useCombat Systems
Open combat when the grid is primarily a force-resolution surface.
View designMaps
Return to maps when representation and readability are the main issues.
Grid matters because discrete local simulation only feels satisfying when its constraints are intentional and tied back to a larger spatial logic.
