Description
This allows you to set desired upgrades for an SACU and add it to the build queue on the gateway.
The enhancements are selected via the same tabs as you would for an SACU when selecting a gateway.
You can then queue it by pressing the button added to the gateway's orders panel.

Note: this demo now contains 4 main factions.

Testing done on the proposed changes.
Basic testing that the upgrades show on the sacu.
Repeat and pause buttons still work.
Energy cost and mass scale with what is selected.

Animation

Build time seems to increase accordingly.
Multiple gateways build different units.

Please let me know of any optimisations I can make.

Disclaimer: AI was used to assist in creation.

This exists as a mod on the faf mod vault as "Custom SACU's"

📝 Walkthrough

Walkthrough

The change generates hidden SACU loadout presets for UEF, Aeon, Cybran, and Seraphim. It adds faction-generic construction and queue handling, combo unit display support, a tooltip, and a restored local development path template.

Changes

SACU loadout feature

Layer / File(s) Summary
Generate hidden SACU presets
lua/system/Blueprints.lua, lua/system/blueprints-sacu-combos.lua
The blueprint pipeline generates hidden enhancement combinations for four SACU factions and marks generated units with SACULOADOUTCOMBO.
Select and queue loadouts
lua/ui/game/sacuLoadout.lua
The module tracks selections per SACU faction, resolves prerequisite chains, finds matching presets, and queues factory commands.
Integrate the construction UI
lua/ui/game/construction.lua, lua/ui/game/layouts/construction_mini.lua, lua/ui/game/orders.lua
Gateway selections use faction-generic enhancement handling, slot clicks, repeat queue controls, and the SacuLoadoutQueue order.
Present combo units
lua/ui/game/unitview.lua, lua/ui/game/unitviewDetail.lua, lua/ui/help/tooltips.lua
Combo units use base faction SACU icons, display their generated names without the standard description suffix, and expose loadout queue help text.

Local development configuration

Layer / File(s) Summary
Restore repository path template
setup/bin/init_local_development.lua
The local development configuration uses the documented repository path placeholder and ends with a newline.

New SACU loadout names and queue help remain untranslated for non-English users. This is a bounded user-interface issue, but localization should be completed before release.

Move sacuLoadout.lua imports to file scope.

The applicable lua/ui guideline requires module-singleton models and controllers to be imported at file scope. lua/ui/game/construction.lua already defines SacuLoadout at line 7; reuse it at the four callback sites. Add the same file-level binding to construction_mini.lua and orders.lua. import caches modules, so this is a dependency-tracking and code-structure correction, not a repeated-module-execution fix.

- Around line 130-140: Update the SACU loadout tooltip title and description
entries in lua/ui/help/tooltips.lua to use stable localization keys matching the
surrounding tooltip definitions. In ComboUnitName and InjectSacuLoadoutPresets,
generate stable <LOC ...> keys for each combination while retaining localization
tags in enhancement fallback labels so the UI’s LOC pass resolves the complete
loadout name.

In `@lua/ui/game/construction.lua`:
- Line 2284: Update the Cybran Gateway enhancement handling around
IsCybranGatewaySelection so the result of EnhanceCommon.GetEnhancements is
defaulted to an empty table before enhancementQueue or existingEnhancements is
indexed. Preserve existing behavior for units with enhancement data and ensure
AddEnhancement can safely access slots when no data exists.

In `@setup/bin/init_local_development.lua`:
- Line 4: Restore locationOfRepository to the documented template value rather
than a personal absolute path, and ensure the template uses a placeholder such
as your-fa-repository-location. Keep any user-configured repository example in
forward-slash form so LuaPlus preserves the intended path separators.

8-8: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Clear or scope selectedBySlot when the active Gateway changes. QueueSelected validates the current Gateway but builds its blueprint from the module-global selections. After selecting a loadout on Gateway A and switching to Gateway B, it can queue Gateway A's combination on Gateway B. The enhancement panel itself does not read selectedBySlot, so this issue affects the queue path only.

Added other factions. Shortened names of generated presets.

Balance:

  • Requires an option to disable an enhancement from being queued in the gateway. This would apply to teleport enhancements.
    UI-wise, the enhancement should appear in the gate but be greyed out as unvailable, with a tooltip explaining that the enhancement cannot be built in the gateway.
    Alternatively, the cost of teleport enhancements has to be made higher and its contribution to sacrifice needs to be disabled. The cost increase would be in proportion to the equivalent mass of mass fab income or pgen income discounted due to adjacency with the tele preset.

UI:
I think it would be good to show enhancements in the bottom bar (the queue) like we have with ACUs. So it would show an SACU icon, the enhancements, a separator bar to indicate it is the preset, and then the next unit.
With such a queue setup, you could create a more consistent queue where you issue a number of SACUs, then pick upgrades (this would restart construction as you are changing the currently built unit), then pick the next unit. It would not require new buttons, it would show what upgrades you have queued in the custom preset, it would allow for modification of queued upgrades instead of needing to re-define the desired preset, and players would have to learn a simpler divider bar instead of a new order button.
This would also elegantly fix the multi-faction/multi-upgradeable-unit issues since you would have a selector for the upgradeable unit in that initial queued unit, off of which you would choose the queued enhancements to determine the preset.

You should make sure the "factory queue preview" option works as intended with the SACU UI.

A lot of annotations are missing.

Put these names in the unit blueprint. Also it needs localized versions.

@lL1l1 Hi. Thanks for all the feedback and tips.
Made the changes you suggested.
Please let me know if I need to make more fixes if you get the time to check.

About the suggested change in functionality.
Its a great idea, but would rather add that as a separate PR later.
I also dont mind if anyone copies this PR and makes their own changes, since this is mostly just a prototype to get the ball rolling.
