Transport_Drones_Continued support by andrevdm · Pull Request #74 · GregorSamsanite/nullius

Summary

Adds support for Transport_Drones_Continued
Transport_Drones_Continued seems to be the most actively supported transport drone fork. Meglinge fork says that it can corrupt save games, so I think Continued is the safer target.
The Continued fork is close enough to the old Transport Drones setup that most of the Nullius compatibility work is mechanical.
Continued does add a few new items and capabilities though, e.g active-depot, storage-depot, drone-dispatcher, depot priorities, and depots that can act as logistic containers. But the new items are similar enough to make recipe selection easy.

Changes & Notes

Supersedes Support Transport_Drones_Meglinge_Fork #73
Added support for Transport_Drones_Continued.
Disallowed Transport_Drones_Meglinge_Fork and Transport_Drones. Given the names are so close, this makes it clearer to users what is currently supported. I also don't think its worth the effort to try support Transport_Drones_Meglinge_Fork yet until it looks active again.
Made the Nullius recipe overrides code more explicit. It is a bit more code, but should be more robust if the mod changes again or if other forks need support later.
Added recipes for the Continued-only items: active-depot, storage-depot, and drone-dispatcher.
Made fast-road its own tech, matching how Transport_Drones_Continued handles it.
Kept fast-road expensive because this matches the existing Nullius recipe choice, though it might still be worth discussing whether it should use regular boxed concrete instead of boxed black concrete. TODO
Continued currently has a quality GUI item & minor road mining bug. I've got a patch I'm trying to submit there to get those fixed.

Detail

Logistics Support

Continued lets depots act as logistic containers. The tech placement now follows the Nullius logistics progression rather than making those capabilities available too early.

transport-active-supply requires transport-buffering and nullius-distribution-2.
transport-logistics requires transport-active-supply and nullius-logistic-robot-1 when active/storage depot unlocks are enabled.
If transport-active-supply has no effects because the relevant depots are disabled (in Continued's settings), transport-logistics falls back to requiring transport-buffering, nullius-distribution-2, and nullius-logistic-robot-1.
Moving logistics after distribution 2 makes the most sense because that is where the matching Nullius logistic chest types become available.
It could be argued that logistic depots should take equivalent logistic chests in their recipes, but that means people who do not enable logistics support still pay for that cost. I left the recipes simpler, and matching the original Nullius ones, rather than adding setting-dependent recipe branches.

Tech / Recipe Gating

transport-system unlocks transport-drone, supply-depot, and road.
transport-system requires nullius-robotics-1, nullius-personal-transportation-1, and nullius-checkpoint-compressed-nitrogen.
This covers hangars/control components and also nullius-car-1, which is needed for the transport-drone recipe.
transport-fluids unlocks fluid-depot and request-depot.
transport-fluids requires transport-system and nullius-pumping-2.
This covers the base depot path and the Nullius fluid-handling parts.
transport-buffering unlocks buffer-depot, fuel-depot, and optionally drone-dispatcher.
transport-buffering requires transport-fluids, because buffer-depot takes request-depot, and fuel-depot takes buffer-depot.
transport-depot-circuits unlocks road-network-reader, transport-depot-reader, and transport-depot-writer.
transport-depot-circuits remains after transport-system and nullius-broadcasting-1.
fast-road unlocks fast-road.
fast-road requires transport-drone-speed-3, transport-depot-circuits, nullius-packaging-4, and nullius-aesthetics-2.
This covers speed progression, road-network-reader, boxed black concrete, and colored concrete production.

Those tables are a bit hard to read with then narrow github rendering. I've copied the comment it to her too: https://www.andrevdm.com/temp/nullius_pr_74.html

rebased on 2.0.6

Try to match the existing nullius recipies for the original transport drones mod. There are a few new items (e.g. drone dispatcher) but they are similar enough so the recipe seemed reasonably obvious. The code is a bit more explicit than before. I.e. more copied inline vs just updating. Hopefully this makes updates later or even possibly supporting different transport drone forks possible if it becomes important. Despite the number of lines changed here, this change was very mechanical and hopefully not to painful to review

… logistics The logistic related transport drone research should come after `distribution 2`, i.e. after the relevant nullius tech is researchd

…sane Disabling transport drone features in the settings should not result in research that unlocks nothing

We assume fast-road exists as its own tech in other places. So conditionaly setting it up does not make sense anymore.

Dissalow Transport_Drones_Meglinge_Fork and the origin Transport_Drones. They wont work as-is. Better to dissalow and make it clear.
