Drug addiction modding

[NielsNederlands1]

Hello all,

Since a couple of weeks I'm interested in modding Rimworld. I succesfully made some mods for myself for learning and to avoid making simple errors for a future more complex mod which i would like to release on the steam workshop. The mod I'm working on adds some more common drugs to the game such as Nicotine (tabacco) and Caffeine (coffee). This all works except for one thing and that is where i need help.

When a colonist gets an dependence/addiction to an added/modded drug it will perfectly show the current need for the drug in the colonist "need tab" and it will fill after the colonist consumes the drug. if the colonist doesnt has access to the drug the withdraw symptoms will kick in.

But the colonist will never automatically consume the modded drug he/she is addicted to, probably this is the case because the drug is not in the drug policy menu and so the colonist doesnt know its actually is allowed to consume it. when the need of the drug is under 30% (and the withdraw symptoms start to effect the colonist) an error will popup (error is provided below) which says some things about the priority.

Can someone help me with this? I would highly appriciate any help i get, i searched through alot of files and topics but was unable to find any information which could help me.

Thanks in advance!

Although I honestly have no idea what that error log really means, couldn't it be that you forgot to add or edit the line

in your drug's ThingDef?

My More Drugs mod adds two new drugs to the game, one of them can addict. Feel free to inspect the xml, you can find it here with the rest of my stuff.

Thanks for the reaction!

I've downloaded you mod and changed my listOrder a couple of times but the error message doesn't change. I also compaired the 2 files together to see if i missed something, but this doesnt seems to be the case.

Do you have another idea why this error might be here? Could it be the colonist doesn't know that a cigarette will satisfy its need for nicotine?

Greetings, Niels.

Interesting. Could you please post your drug's Defs so I can take a look?

Checked it, everything seems fine.

Copy-pasted into my mod, changed costlist to Smokeleaf Leaves so it doesn't throw an error since I don't have the defs for Tobacco, strapped the closest Texture file I had lying around to it and tested it in-game. Cigarettes shown in drug policy, pawn reaches 30%, goes for Cigarettes. No error whatsoever.

Have you actually tested this in a NEW game? Just enable dev mode and test stuff that way. Existing games aren't a good way.

Have you actually tested this in a NEW game? Just enable dev mode and test stuff that way. Existing games aren't a good way.

The problem isn't the old game itself, but using an already existing drug policy because they aren't automatically updated.

For example, the "No drugs" policy still allows addicts to use a drug in order to avoid withdrawal. However, if you add a drug via a mod, said drug will not be part of "No drugs".

You just have to create a new policy and all enabled drugs will be part of that new policy.

There are a few things that behave like that, I'm sure about that. Which is why I simply make a new game every time I test stuff; a lot more convenient than remembering every damn game mechanic that doesn't properly update. And since Dev Mode allows me to generate a planet with only 5% coverage, it takes roughly the same amout of time to generate a new game than to load up a save file.

I didn't know drug policy didn't properly update, though. The more you know.

Thanks alot! This fixed the problem, i am really thankful!
