This page documents the user interface enhancements added by Taj’s Mod. These improvements focus on making the game’s interface more functional, informative, and customizable without altering core gameplay mechanics.

For visual customization features like Extra Glow and Group Colors, see Visual Enhancements. For gameplay-modifying features like Node Limits and Buy Max, see Gameplay Features (Opt-in). For quality-of-life utilities like the Command Palette, see Quality of Life Features.

6-Input Containers

The mod extends inventory containers (storage nodes) to support 6 input slots instead of the default 5. This is an opt-in feature that requires a restart to take effect.

Implementation

The extension is implemented in window_inventory.gd by intercepting the node construction process:

Early Injection - The _enter_tree() method calls _add_sixth_input_early() before the parent class initializes
Config Check - Reads user://tajs_mod_config.json to check if six_input_containers is enabled
Scene Instantiation - Loads res://scenes/input_container.tscn and adds it as the 6th child
Property Cloning - Copies properties from the first input to ensure consistency
Signal Connection - Connects resource signals in _ready() for proper functionality

Sources: extensions/scenes/windows/window_inventory.gd L1-L102

Configuration

The feature is controlled by the six_input_containers configuration key and requires a restart. The settings UI displays a ”⟳” symbol to indicate this requirement.

A navigation panel that allows players to quickly jump to any node group on the board. The feature adds a button in the bottom-left corner of the HUD that opens a popup list of all existing groups.

end

subgraph subGraph0 ["Manager Layer"]

end

Sources: mod_main.gd L342-L386

Positioning and Layout

The Go To Group panel is positioned in the bottom-left corner, above the bottom toolbar:

Anchor Point: Bottom-left (0, 1)
Offset Top: -150px (to avoid toolbar overlap)
Offset Bottom: -80px
Size: 70x70px minimum

This positioning ensures the button doesn’t overlap with existing game UI elements while remaining easily accessible.

Sources: mod_main.gd L368-L385

Configuration

The feature can be toggled on/off without a restart via the goto_group_enabled configuration key:

Setting	Effect
Enabled (default)	Button visible in HUD
Disabled	Button hidden, manager remains active

Sources: mod_main.gd L499-L503

mod_main.gd L330-L331

Settings Panel Organization

The mod’s settings are organized into four tabs for better usability: General, Visuals, Cheats, and Debug. Each tab uses a different icon and contains related settings.

Sticky Notes

The Sticky Notes feature allows players to place editable text notes directly on the canvas. This is useful for annotating complex circuits or leaving reminders.

Manager Setup

The StickyNoteManager is initialized during the main setup phase:

Features

Editable Text: Click to edit note contents
Draggable: Move notes anywhere on the canvas
Persistent: Saved with the game state
Debug Logging: Optional verbose logging when debug mode is enabled

The manager is passed a reference to mod_main to access the _debug_mode property for logging control.

Sources: mod_main.gd L447-L457

Disconnected Node Highlighting

This feature visually highlights nodes that are not connected to the main graph for their connection type (e.g., electricity nodes not connected to a power source).

export() - Same as save(), for blueprint export
_load_custom_data() - Restores pattern and color from metadata

Pattern settings persisted:

pattern_index
pattern_color (as HTML color string)
pattern_alpha
pattern_spacing
pattern_thickness
custom_color (if set)

Strategy Details

Round Robin (290-323):

Groups panels by currency type
Processes each currency group independently
Buys one level from each panel in rotation
Continues until no more purchases possible

Cheapest First (326-351):

Refreshes all panels each iteration
Finds cheapest can_purchase() panel
Purchases and repeats
Optimal for maximizing total purchases

Most Expensive (354-379):

Finds most expensive affordable upgrade
Purchases highest cost item first
Useful for quick progress on expensive upgrades

Top to Bottom (382-398):

Processes panels in UI order
Maxes out each upgrade before moving to next
Predictable and systematic approach

Sources: extensions/scripts/utilities/buy_max_manager.gd L290-L398

UI Styling

The Buy Max button matches the game’s theme:

Theme: Dark blue-grey background (Color(0.086, 0.102, 0.137))
Border: Light blue-grey (Color(0.270, 0.332, 0.457))
Font Size: 28px for main button
Variation: "TabButton" theme type
Popup Styling: Dark theme with rounded corners and proper margins

Z-Order Fix for Node Groups

The NodeGroupZOrderFix ensures that fully contained node groups always render on top of their container groups. This prevents visual issues where nested groups appear behind their parents.
