Update : 10 Jun, 2025
v1.6.0
- Added 1.6 tag preliminarily for new DLC.

Hello Anonymous.
There are multiple mods that add android race, so which mod are you referring to specifically?

Can this mod compatible with Android for RW1.5？

Hi Discomasken.
Thank you for your suggestions, I hope update helped you enjoy RimWorld more.

Started another three week rimworld period yestorday and its nice to see my suggestion was implimented!

Hello Juanca el matador. Thank you for your comment.

Yes. Brain implants can be equipped by pawns other than the player.
In particular, sleepstoppers are cheap, so there is a high chance that they will be equipped.
Of course, they can be removed, so players can also obtain them.

You can also get it from pirates, I caught one alive who was carrying it and took it away for my own interests, good mod.

Update : 10 Dec, 2024
v1.5.1
- In this update, the Parent for the implant surgery has been changed to vanilla implant.
Switched installed sleepstopper implant to vanilla settings. With this update, the difficulty of the surgery is now the same as vanilla standards, so the chance of a surgical error is higher than before. Clean operating rooms and more advanced medicines increase the success rate of implant surgery.

Thanks to Discomasken for this suggestion.

Hello Discomasken.
Thank you for your suggestion. I will try to make Sleepstopper a brain implant, in the same way as Joywire and Painstopper, to match the current RimWorld v1.5 (no prerequisite research specified). It will take some time to update and test.

Could we have the option to either disable the need for "Bionic replacements" research being required to install the SleepStopper, or have it toggle between "Bionic replacements" and "Prosthetics"?

v1.5.0
- Update tags for Rimworld 1.5.x.

Hello Aunt Puff.
Q : Where is the production workbench?
A : Sleepstopper cannot be produced. Whether you get a quest reward, buy at another faction base, or buy from trader.

Q : There is no implant surgery on the menu.
A : 1st, "Install Sleepstopper" requires that Bionics research has been completed.
2nd, a doctor performing surgery requires more than 8 levels of Medicine skills.
3rd, the surgery requires "glitterworld medicine" and sleepstopper, and the patient must be allowed to use "glitterworld medicine".
Please check these conditions. Thank you.

Hey having a problem with the crafting of the sleepstopper. I researched bionics and see that I should've unlocked the sleepstopper from the research menu but I'm looking in every crafting bench i have and can't find out where to craft it. Also been looking in the operation menu of my pawns and cant find a way to implant it there ether. Am i looking in the wrong place to craft it or the wrong place to install it?

v1.4.0
- Update RimWorld 1.4.3509 (unstable).

Surely. The original SleepStopper is a Mod made for RimWorld 1.0, so it is a Mod before Royalty DLC. Therefore, the balance in the DLC may be correct.

I don't think people who work without sleep can be conscious without coffee.

I see sleepstopper as an upgrade, because circadian half-cycler does reduces consciousness

Hello GVLT.
"Circadian half-cycler" is an implant with the same functionality as this mod added in the Royalty DLC.

Normally, if you install Royalty DLC, this mod is unnecessary, so I didn't check it. However, HediffDef for sleepstopper and HediffDef for circadian half-cycler are different and usually do not interfere with each other.

Do you have active another surgical mods that changes brain implant surgery enabled at the same time? This may be caused by a patch that indiscriminately rewrites the contents of HediffDef or a dll that does Harmony patching.

Please confirm whether surgery can be performed only with Core, Royalty DLC, and this Mod as the confirmation method for them. If this mod is the cause, you should be able to reproduce the same issue with that mod list. Please check this method and submit the report again. Thank you.

Hi, for some reasons installing sleepstopper does not remove circadian half-cycler

You can see the market value by looking at the status of the pawn, not the usage value.

I mean, a pawn that doesn't need to sleep without penalties should be worth much more like a regular one, right? Thanks for the reply

Hello Victor!
It's certainly low valuable. Perhaps if increase the value, it will cause the transplanted pawn value to expensive.

Naturally, the asset appreciation of the colony's, which is not commensurate with its combat power, will increase, and the scale of the enemy's attack will increase.

I think it's probably necessary to actually test and find the ideal multiplier with reference to your opinion. Thank you.

I suggest increasing the price for the Sleepstopper a lot, like 5x or 10x, as it is pretty cheap for it's features.

Update : 1 Dec, 2021
v1.3.1
- Changed the sleep need setting to the Royalty DLC method. Sleep need was removed. This update works fine even with Core without DLC. This change will not cause any issues while playing your save game.

Thanks to KingSihv for suggesting this.

@KingSihv
It has already been confirmed that only Royalty DLC is available. Currently I'm testing with some mods. Thank you.

Sure thing. You can see it implemented in Royalty for the half-cycler, under Royalty\Defs\HediffDefs\Hediffs_BodyParts_Bioni_Empire.xml if you need help on syntax.

Hello KingSihv! Thank you for your suggestion.
I'll try it locally. If there is no problem, I will replace it.

Why not use "<disablesNeeds><li>Rest</li></disablesNeeds>" instead of setting the tiredness rate to zero?

Update : 9 Jul, 2021
v1.3.0
- Update for 1.3 Preview beta

Well... there is an unspoken mod that allows hookups during freetime. Or look for hand-holding in the workshop.

@deansdw17
Hello deansdw17. Unfortunately, the premise of Lovin's behavior is that they are sleeping. Therefore, characters who no longer need sleep will no longer act on Lovin.

so vanilla 1.2 now has the half cycler im looking for a way to have a sleepless colony still able to get lovin either on free time or on schedule will this allow that?

You are welcome!

Thanks a lot, and so fast too! :)

@Meownaa
Hello! It is a hairstyle called "LHS M03" included in the Lolidrop's hairshop .

Slightly off topic, but does anyone know what mod the hair with the red ribbon in the first picture is from?

@Daai
Hello Daai.

That's a good question. Probably "exotic goods trader" that handles Implant goods has it. It's not 100% either. You may also be able to purchase them at a friendly "Outlander" colony location.

Question, at which trader sell Sleepstopper? it feel like really rare to obtain

@terrantula
Welcome!

Thx

Update : 3 Sep, 2020
v1.2.3
- add Kurin patch again for 1.1.

Update : 3 Sep, 2020
v1.2.2
- Added compatibility for Androids and Rabbie The Moonrabbit race .
- Fixed the need for sleep. Right now sleep behavior is no longer required.

I'll update it after a little more testing.

@Latex Santa
Hello Latex Santa.
I was doing a test to implement it, but I wasted time because I had forgotten to do the pre-research for surgery. haha.

Androids can now install a sleep stopper.

@Proxyer Would you consider making it compatible with the Androids mod by ChJees?

Update : 23 Aug, 2020
v1.2.1
If you want your pawn to be able to sleep again, you can now remove sleepstopper.

- added new surgery of remove sleepstopper.

@NightCat
Hello NightCat.
The behavior of loving occurs during sleep, so it does not occur when sleep is no longer needed with this mod implant. This is not realistic, but it is inevitable in the RimWorld system. Don't implant your lovers.

If you want your pawn to be able to sleep again, you can now remove sleepstopper (next update: soon).

Am wondering if this mod still allows pawns to have the "Got some lovin' " mood buff as the pawns need to be in bed to do so.
Thanks much!

Update : 13 Aug, 2020
v1.2.0
- Update for 1.2 version build

Hello Spaghetti. Oh! Ok I'll check soon!
