I feel tanks should be invader only. As you have set up a fort, you are a defending force, so instead of tanks I'd recommend stationary defences such as pill boxes (maybe a unit/workshop that runs a syndrome stone reaction giving access to a rapid for "throw" attack?) Or stationary artillary

Posting to watch, ponder and abuse.

Also, there where a few hand held MGs in WWI, mostly lewis guns and the hotchkiss...

Is there a way to add siege weapons? i know that with dwarf hack you can choose the target z-level...
and it might be nice to still be able to dig stone, just have it take an age and a half and leave behind some near-useless item?

[Sergarr]

So I just looked on bronze colossus raws and there's the tissue definition:

Code: [Select]

[TISSUE:BRONZE]
[TISSUE_NAME:bronze:bronze]
[TISSUE_MATERIAL:INORGANIC:BRONZE]
[MUSCULAR]
[FUNCTIONAL]
[STRUCTURAL]
[RELATIVE_THICKNESS:1]
[CONNECTS]
[TISSUE_SHAPE:LAYER]
Try adding some of these and see if that helps.
(Obviously replacing bronze with steel)

[Brilliand]

I don't think there should be tanks in this mod, except possibly in some enemy faction that invades very late.  Tanks were basically the antidote to the horrors of trench warfare, because machine guns didn't do much to them.

Is there a way to add siege weapons? i know that with dwarf hack you can choose the target z-level...

No, but perhaps DFHack could make ballistas smaller (or transform a small building into a ballista that sticks partway into the ground) and make ballista bolts more similar to machine gun bullets.  There's also the option of DFHacking in a moving projectile every time a particular reaction is completed.

Getting the enemies to dig trenches and actually hide in them will probably be the hardest part of this mod.

[Aseaheru]

Good point...
Perhaps in the next version...

[Brilliand]

Good point...
Perhaps in the next version...

I don't think the next release of DF will help with this any.  However, a "digging enemies" DFHack plugin has been released recently, and with a bit of work it could be modified to handle trenches.  Doing something to the "no man's land" terrain to make it unwalkable (floor tiles with really high temperature?) would help with keeping both dwarves and enemies from stupidly walking to their deaths, and might be a reasonable alternative to having machine guns that actually shoot.

[sackhead]

you could use puntams itim sydrome script for machine guns.
when the dwarf sees an hostile it transforms into an imobile creature with a projectile reaction with low cooldown, or the Mg could just be supper heavy so it would be slow moving

Replace the tank's current tissue listing with this, and it should hold up against anything other then profuse whipping and AP crossbows.

I'm quite interested in this mod, and would like to ask if I could borrow and modify the tank's body code for a little side project of mine.

[Just Some Guy]

I've worked on artillery. Artillery relies on weapons called field guns. Here's the raw:

Code: [Select]

[ITEM_WEAPON:ITEM_WEAPON_ARTILLERY]

[RANGED:PIKE:SHELL]
[SHOOT_FORCE:1000]

As you can see, field guns fire shells:

Code: [Select]

[ITEM_AMMO:ITEM_SHELL]
[NAME:shell:shells]
[CLASS:SHELL]
[SIZE:3648]

Notice that shells do not have and attack token. This is because shells can't be forged like normal ammo, but made at a new workshop called a munitions factory. There are two types of shells so far: high explosive and incendiary. Since I used Putnam's Modder Utilities, I had to make seperate materials for shells. Raws here:

To make high explosive shells, you need to make TNT at a laboratory from tallow:

Then you need an assembly line worker (AKA strand extractor) to take the TNT and some steel to make 25 high explosive shells.

Or at least the munitions factory should do all that. None of the reactions work for some strange reason. The shells work fine, I just can't make them.

Yes, I did. They show up, but don't produce anything.

In addition, METAL is a pretty old material token which might get deprecated any day now. It's better to use INORGANIC.

Chlorine is an aspiring war criminal's best friend. It's an essential ingredient in both phosgene and mustard gas production. This is how it's produced at a laboratory:

Code: [Select]

Rock salt + bucket of water + steel barrel + empty bucket = chlorine (in steel barrel) + bucket of lye
To produced phosgene, you need carbon monoxide and activated carbon:

Code: [Select]

barrel of carbon monoxide + steel barrel of chlorine + block of activated carbon + steel barrel = barrel of phosgene.
Then you use the phosgene to make phosghene gas shells at the munitions factory:

Code: [Select]

barrel of phosgene + steel bar = phosgene gas shells [25]

Mustard gas is a bit more complicated. First you need to produce sulfur dichloride at the lab:

Code: [Select]

brimstone + barrel of chlorine + barrel = SCl2
Then you combine it with ethylene:

Code: [Select]

Barrel of SCl2 + ethylene + steel barrel = Mustard gas
To make ethylene, you have to make ethanol at the still:

Code: [Select]

Dwarven sugar + steel barrel = barrel of ethanol

Then you have to combine it with sulfuric acid at the lab:

Code: [Select]

ethanol + sulfuric acid + steel barrel = ethylene

The first of two problems pop up here. I can't decide how to produce sulfuric acid.
Since this mod is inspired by the First World War, any technology developed after 1920 is out of the question, so the wet sulfuric process is eliminated, so I's stuck with the contact and the lead chamber process, both of which, oddly enough, require sulfuric acid.

You may have noticed the second problem already. Note how none of the reactions are in RAW format. That's because I can't decide which item token to use. Any ideas?

I finally got around to doing that, and it holds up pretty well. I just tested how a tank would fare against 24 grand master kobold lashers. It had a few dents, but left no survivors.

As for borrowing the code... go ahead.
