Mods for Oxygen Not Included, built with Harmony 2.0 and PLib.
RimWorld-style colonist bar for ONI. Always visible, always watching your dupes.
A persistent bar showing every duplicant on the current asteroid — stress-colored borders, expression-driven portraits, health bars, alert badges, and detailed hover tooltips. Click any widget to snap the camera to that dupe. Does not affect steam achievements.
- Expression-driven portraits — dupes show contextual facial expressions with periodic blinking
- Stress-colored borders — 5-tier gradient from green to pulsing red, with configurable thresholds
- Health fill bar — vertical drain with green-to-red gradient and damage overlay
- 13 alert types — suffocating, low HP, incapacitated, scalding, hypothermia, irradiated, starving, diseased, bladder, overstressed, overjoyed, stuck, idle
- Animated tooltip — stats with color gradients, active alerts with animated text, rainbow cycling for overjoyed dupes
- In-game Sort/Filter popup — sort by stress, calories, name, or job role; filter by alerts, stress level, job role, or individual dupes
- Multi-row layout with scroll — wraps into rows automatically, scrollbar when rows exceed limit
- Draggable, collapsible, resizable — drag header to reposition, resize grip for portrait size, all persisted
- Respects game UI scale — scales with Options > Graphics > UI Scale slider
- Mod API — other mods can register custom alerts, hook tooltips, and listen to events (API Guide)
- 7 languages — Chinese, Korean, Russian, Japanese, German, Spanish, French
Replace existing buildings with upgraded versions without deconstructing first. Supports tiles, doors, ladders, fire poles, and more — including modded doors (e.g., Fast Insulated Self Sealing AirLock).
- Footprint-strict replacement groups (same width x height only)
- Vanilla replacement pipeline integration (
TryReplaceTile,ReplacementTags) - Multi-cell tile cleanup for non-anchor cells
Build and deconstruct through walls. Transpiler-based patching of the offset table to bypass solid cell checks.
In-game performance profiler toggled with backtick/F8. Instruments 29+ game systems, PlayerLoop phases, 193 bulk Update methods, and coroutine census. Zero overhead when closed.
- Spike capture with pre-allocated pools (zero GC)
- Data recording to CSV with interval accumulation
- Stopwatch-based frame timing (fixes one-frame offset bug)
Alloc-gated garbage collection — triple-gate system (frame budget, cooldown, alloc threshold) to reduce GC stutter spikes. Proof of concept for mitigating Unity Mono's non-incremental GC pauses.
