Board Layout and Sizing

Expert knowledge of Board display layout, coordinate systems, SVG import settings, and sprite sizing for the 1920×1080 Board hardware.

Display Configuration

Target Display

Camera Settings

Calculation: Visible Height = orthoSize × 2 = 10.8 world units

Horizontal Layout (19.2 world units)

|  Blue UI  | Blue Res | Buffer |   5×5 Grid   | Buffer | Red Res |  Red UI  |
|    2.1    |   2.0    |  0.5   |     10.0     |  0.5   |   2.0   |   2.1    |

Zone Coordinates

Reserve Pool Purpose

• Holds drawn tiles before placement (visible to both players)
• Up to 3 tiles per player maximum
• Tiles can be stolen from opponent's reserve

Vertical Layout (10.8 world units)

LayoutConfig Reference

All layout constants centralized in Assets/Scripts/Config/LayoutConfig.cs:

public static class LayoutConfig
{
    // Screen dimensions
    public const float ScreenWidth = 19.2f;
    public const float ScreenHeight = 10.8f;

    // Tile and grid
    public const float TileSize = 2.0f;
    public const int GridSize = 5;

    // Grid boundaries
    public const float GridLeft = -5.0f;
    public const float GridRight = 5.0f;
    public const float GridBottom = -5.0f;
    public const float GridTop = 5.0f;

    // Camera
    public const float CameraOrthoSize = 5.4f;

    // Reserve zones
    public const float BlueReserveCenter = -6.5f;
    public const float RedReserveCenter = 6.5f;
}

Grid Positioning

Grid to World Conversion

// Grid (0,0) to (4,4) maps to world coordinates
float x = LayoutConfig.GridLeft + (gridX * LayoutConfig.TileSize) + (LayoutConfig.TileSize / 2f);
float y = LayoutConfig.GridBottom + (gridY * LayoutConfig.TileSize) + (LayoutConfig.TileSize / 2f);

Formula: Texture Size = Desired World Size × 100

Standard Settings

Import Steps

1. Select SVG file(s) in Project window
2. In Inspector:
   • Generated Asset Type: Texture2D
   • Texture Size: (calculated value)
   • Pixels Per Unit: 100
3. Click Apply

Common Mistakes

Rendering Order

Higher sorting order = renders in front.

Grid Visibility

Grid MUST have higher sorting order than tiles (1-2 vs 0) to appear above them.

Player Orientation

Players sit facing each other:

• Blue player: Views from LEFT side (x < 0)
• Red player: Views from RIGHT side (x > 0)

UI text rotation:

• Blue UI: Normal rotation (readable from left)
• Red UI: Rotated 180° (readable from right)

Edge Node Positions

Each tile has 4 edge nodes at side midpoints:

Token Snapping

• NodeSnapDistance = 0.5 world units (appropriate for TokenSize = 0.4)
• Tokens snap to the nearest edge node within snap distance

EdgeNode and Tile Rotation

EdgeNode values (Top, Right, Bottom, Left) are tile-local coordinates that rotate with the tile:

// Rotate edge node by rotation steps (each step = 90 degrees clockwise)
public static EdgeNode RotateEdge(EdgeNode node, int rotationSteps)
{
    return (EdgeNode)(((int)node + rotationSteps) % 4);
}

// Example: A path from Left to Top on an unrotated tile
// After 1 rotation step (90 CW): becomes Bottom to Right

Center Tile Special Case:

• Center tile (game-tile-13) is the ONLY tile that cannot rotate
• Blue Attack starts on Left node, Red Attack starts on Right node
• These starting positions are fixed and hardcoded per game rules

Coordinate System Summary

                    World Y
                       ↑
                       |  +5.4 (screen top)
                       |  +5.0 (grid top)
                       |
-9.6 ←─────────────────┼─────────────────→ +9.6  World X
                       |
                       |  -5.0 (grid bottom)
                       |  -5.4 (screen bottom)
                       ↓

Troubleshooting

Camera not showing full screen

Cause: Wrong orthographic size Solution: Set Camera → Orthographic Size = 5.4

Tiles too large/small

Cause: Wrong SVG Texture Size Solution: Texture Size = World Size × 100

• Tiles: 200 (2.0 × 100)
• Tokens: 40 (0.4 × 100)

Grid lines hidden behind tiles

Cause: Sorting order wrong Solution: Grid sorting order (1-2) must be higher than tiles (0)

Sprites not aligning

Cause: Not using LayoutConfig Solution: Always use LayoutConfig constants for positioning

Why 5×5 Grid?

• Balanced gameplay: Enough space for strategy, small enough for quick games
• Fits display: 10.0 world units fills the 1920×1080 display with room for UI
• Network aesthetic: 5×5 creates interconnected network paths matching cybersecurity theme

Quick Reference

PPU = 100 (ALWAYS)
Texture Size = World Size × 100
NodeSnapDistance = 0.5 world units

Tiles:  2.0 world units → Texture Size = 200
Tokens: 0.4 world units → Texture Size = 40
