Made an update of this:

Hope it helps anyone!

check with Mlie, They normally do great support on mods out of support.

I hope this gets an update; i haven't seen another mod that does something similar.

Is this mod presently being worked on for 1.5? Not trying to pressure and be one of those "Hey where is the 1.5 update already!!!" people, but wonder if the project is being actively worked vs potentially open for someone to try and make a fork/alternate version. Thank you....

From description:
Future Ideas?
* Options for everything"

I'm not sure if you're still planning to expand on this mod. But, I do know of two mod libraries for RimWorld that are supposed to make the addition of Mod Options to a mod a breeze:

XML Extensions has in their description: "Extends functionality of XML patch operations & allows for easy creation of Mod Options. This adds many new patch operations for modders to use. These operations are much more powerful and dynamic, and allow you to basically do programming in XML; you have access to if-statements, for-loops, mathematical operations, etc. Now you can easily create mod settings for your mod, all in XML!"

ToolBox (Continued) says, "XML based framework for making mod settings that allow changes to ThingDef"

I love this mod for Hegemonic Pawns, but I have a problem where pawns will only eat the Hemogen Packs if they were starving.

@FrozenSnowFox how did you make that patch? (blood pack preferability). I'd really love to do something similar. Please help!

Not sure if this would be in scope of this mod or if it needs VSE attention - a blood-type alcohol or alcohols = bloodwine / bloodbeer, etc. This would also hit the hemogen and food gained hediffs, plus chemical satisfaction just like vanilla alcohol does and now your food options do. Would also lower consciousness levels and move and aim, so the drunken / coked up raider sanguophages can be appropriately ready for their oncoming event. That would also perhaps ameliorate the overpower that sanguophages might have vs. my naked brutality guy.

Does this work with Vanilla Expanded Sanguophage bloodfeed types added?

I love this mod's thumbnail. Made me chuckle.

Vanilla expanded sanguophages adds in new sanguo sub types one a pretty vamp feeds on normal peps and other sanguophages giving mood boosts

another the Strigoi can feed on animals and people

While the third eikman (or somehting like that) feed on corpses

@ShadowX I'm not sure I understand what you mean. While you cannot feed on, say, a trader, you can feed on pawns you defeat. If you down someone, you can feed on them, so you don't have to imprison the raiders that attack you in order to feed on them. In fact, that's how I tend to finish off any raiders who survive.

can vampires survive without hemogen and only food with this mod?

@ShadowX That would have been ideal. I'm not a big fan of how vamps were imagined in this DLC. There might be some xenotype mods around on the workshop that have genes that remove hunger, then you can just add that gene to the sanguophages.

like, they should be able to feed on someone they just defeated, say

I wish vampires could feed on things other than prisoners, colonists and slaves

Wouldn't a better way to handle this mod be to remove hunger for vampires entirely, rather, make blood their new hunger bar?

I don't know why I didn't think of this earlier. I patched the blood pack food preferability from DesperateOnly to MealAwful to match paste meals and now they eat blood packs without waiting until they're dying of malnutrition. As a side effect they even put a blood pack in their inventory to eat for later just like normal meals.

@Imoja
One way you could make vampires feed regularly is by creating some custom meals that are only made with hemogen packs or simply allow hemogen packs in meals. Then if possible you could even add a "blood" tag much like the "Meat" and "Vegetables" tags. Its a little silly in some ways but it would prevent the major issues of messing with other areas.

It does say it's based on body size, so maybe it has something to do with the body size genes mods added.

Blood feed doesn't see to fulfill the food need even though I set it to 1.00 in the mod settings. Is there something I am missing? I am pretty dumb, so I wouldn't be surprised.

You can change how frequently pawns drink hemogen by adjusting the hemogen refill slider bar gizmo. Sadly, this is the only way i have found to make pawns drink hemogen, I tried playing with the diet/food priorities but it was very complex and more often than not it would break numerous other mods that work with this.

Man this is a great mod, I literally bought this game because of biotech. The fact that vampires need food and blood is basically just an addiction is just straight tardy. Unfortunately, in it's current state, it's nearly unusable on higher difficulties and/or with large colonies because pawns don't like to actually drink the hemogen until they're malnourished, so unless you want to manually feed 10-20 people every 2 minutes, you're going to be swimming in mental breaks. Or let them eat other things too, which defeats the purpose. Gonna have to unsub for now, will keep an eye out if you fix that issue.

Glad you like the mod. Adjust the food gain in the options.

I love this! Only issue I have is that it seems when I make them only drink hemo they end up getting malnourished

I'd love an option that increases how much hemogen you get per feeding/pack. Currently it really feels like you get too little per feeding given how long it takes for blood loss to recover.

can we get a version, or options later for removing the mood changes for drinking it?

Removed the patch operations that now perform vanilla behaviours. Sorry about the delay.

The new hotfix removed the need for medicine when doing the hemogen extraction surgery so your patch is erroring.

What changed with the update? My game errors on launch now (and quite frankly I've never had to send an error log would love to know where and which file to put on pastebin if that would be helpful)

Great to hear!
Now my vamps can enjoy a nice cooled sip, while no longer being euphoric from their daily biting :)

@Ads: I've added a checkbox for enabling/disabling the mood buff from Blood Feeding, I cant make any options for the Hemogen Pack yet because I don't know how to do so lol. I'm working on that though.

Having my lil biters get sustenance from their human snacks is great, but would it be possible to add a slider to edit the mood gains, or even just an option to disable them entirely?

@KAiFoLoG: If your pawn likes to eat human flesh, they will not be satisfied by drinking human blood. Modifying the way cannibalism works would be outside the scope of this mod, my apologies.

@ZuluFox: Great catch, I likely would never have noticed this. I will see what I can do about it but I'm honestly a bit concerned that Skill XP is calculated based on the Work Amount, I had a look today but couldn't find it, but its going on the board.

What about idealogy?) If my colony has cannibal idealogy, does Sanguophage need eat human meet?)
Also u can add rarity of blood depends on medcine skill, or gene like blood type, so if Sanguophage take bad blood so he get minus mood buff
but it's just а suggestion

You might want to consider making the blood extraction surgery give less experience, in Vanilla it's already op even with the requirement of 1 herbal medicine, so without it you are just getting a huge amount of medical experience for basically no cost

@winternallyscreaming: already spotted it and said hi to the Dev. If they don't play well together I will try to patch support myself, thank you for your support. Hope this mod improves the fun you have

Also, there’s a mod 'hemofungus' which adds a fungus that creates hemogen, which sounds like it would be great for 'ethical' sanguophage playthroughs or when their colony's ideology includes vegetarianism. For simplicity's sake I will stick with just yours for now, but I wonder if both mods would play nice together out of the box, or if a patch might be needed. Could be something to look into maybe?

Thank goodness! Just got Biotech, been looking for this mod since my first 5 minutes of playing. Sanguophages going after normal food was equal parts startling and irritating when I first saw it. It makes zero sense for them to have BOTH food and blood needs. There are already considerable disadvantages to sanguophages that serve as balance (weakness to daylight and fire, need to rest) without them going after the others’ food.

Lack of medicine requirement is also great; blood donation doesn’t need anesthesia in real life, so why here? Good touch. Definitely rooting for your idea of hemogenic pawns preferring hemogen too.

Latest update has a slider in the mod options so you can decide yourself how much food bloodfeed rewards, stay tuned.

FUCK YES, THIS MOD IS NOW A MUST-HAVE

I tested it at about 2:00 and it worked fine. I have to say this mod is pretty great. Thank you for listening to player feedback, I hope more people use this mod.

Quick update, The surgery to Extract Hemogen Packs no longer requires medicine, nor anaesthetises pawns. I was considering adding a debuff, but the -20% consciousness from the blood loss seemed severe enough.

@Gafronkis: I have double checked BloodFeed with many different xenotypes and body sizes now and im unable to recreate the problem you had where drinking resulted in less than 1.0 Food. If you continue to experience it after this little update let me know.

@Ms KarMagick: Whilst this does seem like an interesting idea, I'll be honest I have no idea how simple or complex it will be to implement. Its going on the board though so time will tell.

@ZuluFox: This is happening because when Hemogenic pawns are hungry for FOOD, they dont consider HemogenPacks, because they still arent a "Food" yet (to avoid many other issues).
I personally resolved this by increasing the % at which they seek to top up hemogen. It varies but I have it set to 80% currently. I will look into fixing this.

I did, yes and I love it so far. One small note is that if I make a food restriction where they are restricted to only hemogen they seem to not want to eat until they have -20 for malnourishment, any chance it could be related to this mod?

With the planned features you've got, this seems like it's going to turn into a hemogen pack overhaul right? Have a suggestion for you; Feeding on (or making a blood pack from) a sick pawn (infection, food poisoning, tox, etc) resulting into food poisoning for the sanguo feeding on said pawn, or consuming blood packs made from them

You could copy and rewrite the anesthetic effect, as it's similar to what you're going for dizzy wise.

Firstly, thank you for your feedback regarding improvements and balancing.

I have just updated the balance again to provide 100% food on BloodFeed and HemogenPacks, whilst very slightly lowering the mood buff.

I will look into removing the medicine requirement, and the anaesthetic effect from the extract HemogenPack option soon, and perhaps replace it with a custom debuff called "Feeling Woozy" or something similar that makes pawns dizzy and uncoordinated after an extraction, perhaps it can apply to BloodFeed too.

Im also going to look into creating an options window that will allow everyone to define the balance they would prefer, this is all very new to me. (Coding, not C#. lol) so bear will me and hopefully together we can have lovely little QoL mod that might stand the test of time this game will undoubtedly endure with ease.

Please keep up the feedback, it is very much appreciated.

blood feed i think also takes the same amount of blood out of the person as extracting a blood pack so does make sense it would be equal, could always adjust balance by making seperate genes though, like a gene that makes it so u get less nutriton or more nutrion from blood feed, lots of ways to balance this

These are just suggestions, I'm sorry if it seems like I'm barging in here being rude, I just liked the mod and wanted to understand the reasoning behind design decisions and maybe suggest improvements.

Also to clarify, when I say hemogen packs having more nutrition might be reconsidered, I am not saying lower the nutrition value, I am saying to keep it the same but raise the value for bloodfeeding to either close to the same value or the same to reflect that they are essentially the same amount of blood.
