Key Features
- Add Mining Efficiency technology that reduce the ore consumed by all mining drills
- 7 levels
- Reaching the max level effectively multiplies ore yield by ×100
- Each level improve efficiency by 2
- Quality does not affect the resource drain percentage
- Quality affect the speed of drills:
speed = base_speed * (1 + (QualityLevel * 0.3))(Default vanilla) - Quality affect energy usage
energy = base_energy * (1 + (QualityLevel * 0.3))(Default vanilla) - Quality affect mining radius
- Quality affect module slot count up to 9 for legendary.
- All Mining drills have a starting 100% resource drain
Gameplay Impact
- Solves the issue where mining productivity makes output rate of drills insane
- Mining drills must actually work - ore patches size matter
- Makes extra oil mining outpost relevant in late game
- Makes productivity modules in mining drills meaningful
- Design proper beaconed mining setups
- Productivity is multiplicative with resource drain. At max level and +100% productivity that would results in ×200 total ore. So legendary module + legendary big mining drill would give +225% prod that result in max x325 total ore. So max with this mod alone is equivalent to +32500% productivity.
Stats
Comparison cost between Mining Efficiency and Mining Production.
| Mining Efficiency Level | cumulative | Mining Production Level | cumulative |
|---|---|---|---|
| 1 | 729 | 10 | 137 500 |
| 2 | 7 290 | 40 | 2 050 000 |
| 3 | 66 339 | 80 | 8 100 000 |
| 4 | 597 780 | 160 | 32 200 000 |
| 5 | 5 380 749 | 320 | 128 400 000 |
| 6 | 48 427 470 | 640 | 512 800 000 |
| 7 | 435 847 959 | 1000 | 1 251 250 000 |
It's less but I nerfed base mining drain of big mining drill and quality doesn't increase mining drain so I feel that normal it's cost less. I still need testing to see if I need to lower it again.
Technical Notes
- Removes the vanilla Mining Productivity technology by default
- UPS impact is almost zero
- Only runs on research completion (
O(n)) - Or when an entity is built (
O(1))
- Only runs on research completion (
- This version is close to what I want for 1.0.0, tested a bit.
Known issue
- Special Mining drills are not hidden: https://forums.factorio.com/viewtopic.php?t=132058
Also, if they were hidden you would not be able to use planner so... in the end while this annoyed me at first, this issue force me to have better idea for the mod, improving icons, localization text, help the user to understand what is what and so user can use planner upgrade way more easily. The noise of not hide mining drills is minimal.
