What's new

Colossal Reactors 2.6.0.0.0

Dependencies:

  • Requires: Iskandert's Library 1.13.0.0.0+
  • Requires: Another Config Manager 1.0.0.0.0+

Also available for NeoForge 26.1.2 (same feature set as 1.21.1).

Note: the third-party website (ModDecoded) may not be updated right away for the new mdct2 / mdcr2 seeds and builder changes, but it should be very soon. Many thanks to Mod Decoded for the changes made to the website!

Features:

  • Turbine Builder modes reworked: pattern cycle is now Website → Flow → HyperFlow → Custom → None (default Website).
    • Flow — single center shaft.
    • HyperFlow — best multi-rod grid for the footprint (same pick as ModDecoded Rod grid: odd-odd or staggered), with a rod controller on every column. Efficient / Productive rings are capped to that layout’s best ring.
    • Under Flow / HyperFlow, a long control in the Website seed slot toggles Efficient (climb rings) ↔ Productive (full rings); default Efficient when switching into those modes. Custom / None show the same slot empty and disabled; Website keeps the seed EditBox.
  • HyperFlow + Productive on the classic 9×9×9 gold / 1 coil family stays in the ~560 000 RF/t ballpark where that footprint picks stagger. HyperFlow + Efficient uses climb on the same columns (~542 000). Website seeds still drive climb (c) vs full (f) from the design code.
  • Two coil materials on the Turbine Builder: zone coil (right-block control) fills coil-zone cells that are not above rods; rod-column coil (beside Efficient / seed EditBox) fills cells above rod columns (steam flow path). Website import sets both from the seed; you can diverge them afterward.
  • Website seeds mdct2 / mdcr2: material fields can carry datapack recipe selectors (~c:storage_blocks/gold = #c:… — tilde so share URLs stay intact). Short ids (gold, …) still work via optional config CSV maps (000_coil_selector_map / 001_heatsink_selector_map); without a CSV entry the builders encode/resolve as mdct2/mdcr2 selectors from valid_blocks / valid_liquids.
  • Electromagnetic coil flow stats (flow_coe / flow_max in datapack): averaged only over coil cells in columns above Turbine Rod Controllers, then multiply the turbine’s max steam throughput. Defaults 1.0 when omitted.
    • Builtin flow ladder: iron 1.25/1.35, lapis 1.10/1.20, redstone & steel 1.50/1.65, stainless steel 2.00/2.20, crying obsidian 2.80/3.00; other coils keep flow at 1.0 when omitted.
    • Coil-depth bonus (config): extra useful coil layers add a capped steam bonus (default max +20%; target layers ≈ round(exteriorAlong / 10) × footprint factor, e.g. exterior 16→2, 32→3, 64→6; blade-count gate). Layers above the target do nothing; non-Website builder clamps coil layers to that target (Website seeds unchanged for now).
    • Efficiency tweaks on several tiers (including crying eff_coe 1.0 / eff_max 1.5). JEI / EMI / REI show Flow coefficient and Flow limit (EN + IT).
  • GuideME (EN + IT) and lang (en_us / it_it) updated for modes, HyperFlow, dual coil controls, and coil flow.
  • Builder GUIs use 250×250 backgrounds (was 230 wide); controls recentered with wider pattern buttons. Fluid tank + dump aligned with Mark Input (FLUID_BAR_Y 28). Simulation submenu still inherits the 230×240 controller texture and layout (buttons / title / close), not the builder 250 width.
  • Builder world preview upgraded: outer shell via iska InsetAreaBorder (thick 6/16 beams fully inside the footprint); rods, blades, and controllers as long through-wall prisms; turbine closure deck as one rectangle (not per-cell cubes); wrong-block occupied markers stay depth-tested and merged. MarkRenderer X-ray defaults for utils/scanner unchanged (owned-box list fix in iska 1.13).

Tweaks:

  • Turbine Website import: if the seed uses coil fill one (o), the builder still fills the whole coil zone (same contract as ModDecoded’s Builder path); GUI shows a short hint instead of simulating a single coil block.
  • Reactor Builder Simulation on 1.21.1: fuel consumption uses the same fuelRodFactor / rodFuelScaling path as NeoForge 26 (parity with CR-26).
  • Reactor Builder Website seed EditBox width matches the three right-button columns.
  • Website design code EditBox no longer capped at 512 characters; network codec allows seeds up to ~1 MiB.
  • pt_br translation and GuideME guide updated. Many thanks to Princess Stellar!

Bug Fixes:

  • Turbine Builder coil placement with tag recipes (#c:…): auto-build now places the block from the builder buffer that matches the selected coil, instead of always placing the first block in the tag (while still consuming the inventory item).
  • Turbine Builder zone/rod coil (and Reactor heat-sink) selection no longer snaps back to Air when the GUI syncs before datapack coil/heatsink options are loaded on the client (early ContainerData clamp).
  • Reactor Website Simulation: air cells count as heat sinks again (like runtime / ModDecoded), with per-cell heat-sink modifiers from the seed. Material estimates still skip air (nothing to place). Hybrid air + metal layouts no longer look like “no heat sinks”.
  • Multi-rod turbines: builder / metrics no longer pre-cap blade rings with neighbor Chebyshev clearance (that forced ~400 000 RF/t on the classic Hyperflow / Website full seed). Rings follow pattern / seed + shell limits; placement still stops on real collisions.
  • HyperFlow follows ModDecoded bestLayout (not a fixed stagger-only grid), so sizes that prefer odd-odd match the site Rod grid.
  • Reactor Builder Frame pattern: places true 1-block-wide concentric rings with heat-sink gaps (plus optional center), scaling ring count to rod-space size — not a hard cap of three rings, and not thick filled bands with a hole.
  • Reactor rod inside tint: when fuel lives on the controller and rods are empty, tint is pushed from the controller so rods no longer stick on the uranium-green fallback for every fuel.
  • Turbine Builder right-click (decrement / previous) on size and option controls plays the UI click sound.
  • Coil-depth target: useful layer count uses exterior rotor length (interior + casing), not bare interior — a 16×16×16 turbine correctly allows 2 coil layers again (was stuck at 1).
  • Builder Simulation submenu: steam / coolant / fuel controls, title, and close button use controller 230 geometry after the builder widened to 250 (no overflow past the controller panel).
  • Builder Offset (« / ») buttons now show their existing lang tooltips (were defined but not wired).
