Underground Pipes v0.9.22

The whole interface now ships with 12 languages including Russian, and it picks up your game language automatically. Thanks for the suggestion! 🙂

What's fixed:

• X-ray invisible after the first save load. On a fresh game start the buried-pipe x-ray (and the hover read-out) stayed hidden until you clicked any build tool. Integer overflow in the tool-active check — fixed, shows right away now. (Thanks warrenc for the repro.)
• Settings gear button missing. Two causes: on save loads the mod grabbed the HUD too early and gave up; and with Speed++ installed the button was placed but instantly hidden by its speed-bar cleanup. Both fixed — the gear now always appears in the top speed bar.
• "From → to" block showed on conveyor belts. The game uses one inspector for all transports; the block now shows only on fluid pipes.
• "From → to" block duplicated after loading a save. The mod re-applied its patches on every load, stacking a copy each time. Patches now apply once.
• Stale from → to info. If you re-plumbed the network while the inspector was open on the same pipe, it kept showing the old source/destination. Now re-checks automatically.

This update fixes the missing settings gear button (the one in the top game-speed bar) - reported on the forum, much appreciated! Two root causes, both fixed:

Fixed: gear button missing when loading a saved game. The mod resolved the game's HUD during early init, which works on a new game but fails on a save load (the HUD is built a few seconds later there). It gave up permanently, so the button never appeared. The mod now resolves the HUD lazily and keeps retrying until it's ready - the gear shows up a few seconds after the save loads.

Fixed: gear button hidden when Speed++ is installed. Speed++ replaces the vanilla speed buttons by hiding every standard icon-button in that row - and the gear matched its filter, so it was placed and instantly hidden (on new games too). The gear is now a dedicated button type that isn't affected, plus a watchdog re-shows it every couple of seconds in case any other mod hides it.

Nothing else changed in this release - if 0.9.15 works for you and you always saw the gear, there's nothing new to see. If you ever lost the settings button, this one's for you.

As always: if something looks wrong, post in the forum thread and I'll fix it.

🔎 Pipe inspector, built right into the game's panel
Click any pipe (buried or on the surface) and the game's own pipe panel now gets a "source → destination" section: it shows the real building that feeds the pipe and the one it feeds — clicking either icon flies the camera straight there. If an end is a storage tank, it also shows how full it is (e.g. from 4/400 (1%) → to 320/400 (80%)), updated live.

It's smart about routing, too: the trace walks through connectors, balancers, zippers and distributors (including Gameplay++'s Pipe Balancer/Connector) and stops at the actual machine or tank — so you see where the fluid really comes from, not the junction in the middle.

🖱 Richer hover read-out
Point at any pipe and you get a clean read-out at the cursor: the flowing product, the real amount, how full the pipe is, and the source/destination building icons on either side. No jitter, no clutter.

⚙️ Proper in-game settings
There's now a gear button slotted into the top game-speed bar (next to pause/play). It opens a native window (title bar, close, pin, draggable) where you can toggle everything, pick a colour scheme (click a swatch), and — by popular request — adjust the overall x-ray brightness with a slider if the pipes look too bright.

🎨 Colour & visibility

• Pick from several ready-made x-ray colour schemes, or set your own hex colours.
• Global brightness/opacity slider for the whole overlay (defaults are dimmer now, so pipes sit nicely in the background).
• Colour the buried network by product instead of by depth.

🧰 Compatibility & fixes

• Full Cheat++ coexistence (one button frees both mods' delete protection).
• Fixed the hover amount (it used to read half), fixed tank fill readings, rounded pipe length, and a pile of alignment/polish fixes.

As always — no new buildings or assets, just your normal pipes routed underground.

Update 0.9.1 — Cheat++ compatibility

• Fixed the conflict with Cheat++ over deleting buried pipes — before, you had to enable it in both mods; now one button frees both, and pipes stay protected by default.
• The "delete buried pipes" toggle now always starts OFF when you load a game, so you can't accidentally bulldoze pipes by leaving it on.

0.8.1 — stability fix
🪲 Fixed an internal error ("collection modified during iteration") that could fire while building or connecting buried pipes — the overlay was reading the game's live pipe list at the same moment a pipe was being placed, which interrupted the toolbar's input handling and made underground connections unstable. The overlay now draws from a safe snapshot, so building and connecting buried pipes is solid.
🔍 Fixed the hover read-out spamming an internal assert when the cursor was near the map edge.

🔧 Depth now scales with your pipe tier (vanilla-style progression, not a free cheat):
• Tier 1 pipe → 1 level underground
• Tier 2+ pipe → 2 levels underground
Since pipe tiers are unlocked through research, deeper routing is something you earn. (A pipe still can't be built below sea level.)

🎨 Colour-coded placement — while routing a buried pipe, the preview is tinted by validity: green = OK, amber = at the depth limit, red = invalid (e.g. it would dip below sea level). The limit is now visible, not guesswork.

🔍 Hover read-out — point at any pipe (buried or on the surface) to see what's flowing through it as a big product icon at the cursor, without digging or opening it.

🪲 Polish — toolbar buttons now line up flush with the rest of the bar, plus stability fixes.
