PROCEDURAL RESEARCH TREE
Improvements for the research tree for modding. Full language support
Overlapping Progression lines
↓ Auto-Layout helps prevent overlapling when when two mod's register nodes on top of each other. ↑
EXTended pre-requisite details
← Click-to-Navigate forward and backwards to all connected nodes →
Filter by mod
🔍 Identify all nodes that belong to any mod.
Use only the features you want
All features can be toggled on/off using the bottom left buttons, including restoring the tree's original layout.
Auto-layout will expand the scrollable area only when it needs more space to display additional mod progression lines.
Auto Layout
• The goal is a solution for healthy mod community-research-creep so we don't end up with 100s of overlapping nodes as more mods add more custom research.
Help improve the mod
Feedback is appreciated to help improve auto layouts presentation. If any research from a certain mod looks weird you may post pictures on the forum.
You can also use PRT_Tree console command to log the tree's layout result to report any issues while using default layout settings.

Changelog
* Verifies compatibility with Captain of Industry v0.8.7d. * A special thanks to SirColibri, author of Colibri Industries, for helping brainstorm ideas during this mod's development. Now our overlapping research nodes are close cousins, once removed = ) * Adds Colibri Industries as an optional mod. * Corrects the opacity slider display so its label matches the actual 0%-50% opacity range while highlighting nodes. * Left-clicking to close the Filter Menu maintains it's gold coloring—indicating a filter is still active.

Changelog
* Adds editable English-key translations for all 21 supported game languages. * Adds small research-window controls for all features. * Adds alternative layout options, including Original Vanilla Layout to rebuild the research tree live, without needing to restart. * Adds clickable REQUIRED BY details for complete two-way tree navigation. * Adds Mod Highlighting to identify nodes belonging to a selected mod: Filter by 1 mod, all mods, or vanilla-only. * 0%-50% opacity slider appears only while filtering is active; Dims all other nodes. * Adds PRT_TREE console command for logging the auto layout's result for use in reporting issues. * Kept some testing layouts: Compact, Nearest, and Packed layouts with spacing 1 through 4; Compact 3 is the PRT default, while spacing of 1 or 2 allows some overlap to occur in exchange for less overall height. More improvements to layout can be made as needed/suggested. NOTES: If an author patches their own REQUIRED or REQUIRED BY Details, then PRT skips modifying that node's details to avoid duplications. This does not guarantee an author adds their own click-navigation.

Changelog
* Public no-Harmony alternative * Adaptive-layout foundation. * Keeps the vanilla research tree fixed as the progression backbone. * Detects connected per-mod research branches and preserves their authored shape. * Moves colliding branches only by deterministic four-grid-unit vertical offsets. * Repairs malformed overlaps inside a connected branch without changing horizontal progression. * Runs after all normal research prototypes are registered and again before the research window builds. * Never changes prerequisites, research costs, unlocks, conditions, or saved research state.
