About Searchlight 2
From Factorio Mod PortalBased on the Searchlight mod by DukeDublin, now made compatible with 2.0 & Spaceage! Build long range Searchlights that track enemies, especially fun with the Diurnal Dynamics mod
Searchlight 2 ========== Based on the work done by DukeDublin: <https://mods.factorio.com/mod/Searchlight> I have reworked the Searchlight mod to be compatible with 2.0.
What does the mod do?
Searchlight 2 adds a new lamp type after researching the lamp upgrade. This "searchlight" acts like a turret and will follow enemies in its range and cast a beam of light to illuminate the enemy and anything in between. This mod is fun on its own, but I highly recommend using it with <https://mods.factorio.com/mod/diurnal-dynamics> to get the most out of both mods. Feedback and suggestions are always welcome; I'll try my best to respond swiftly to any comments.
- All screenshots were taken with Diurnal Dynamics; without this mod, nighttime will be much brighter.
Updates: ======= V2.0.1
- Fixed a bug where the graphics folder was incorrectly referenced in the source code
V2.1.0
- Searchlight now switches faster between targets
- Searchlight will prioritise the nearest target
V2.2.0
- Searchlights will now avoid targeting the same targets
V2.3.0
- Improved UPS drastically by changing the retarget algorithm to run less often
