I was having trouble with assigning a more general chemical_spray ammo-type. I wanted something like this:
{
"type" : "ammunition_type",
"id" : "chemical_spray",
"name" : "sprayable chemical",
"default" : "gas_fungicidal"
}

But it throws a debug-message, saying gas_fungicidal is not a valid ammo.

Sounds like you only changed it in ammo_types, but not in ammo.json: "gas_fungicidal" had the old "ammo_type" field.

"ammo" field refers to the ammo type id. So if you're changing ammo id to "chemical_spray", the fungicidal gas needs "ammo_type": "chemical_spray".

That's it! Also, it makes much more sense, now that I think about it.

Fire 100 is quite a lot. With flamethrowers you can acquire the ammo easily by siphoning it from cars. Here you've got to craft every shot.

Fire 20 or 50 should be fine, unless you intend to make the gas very powerful.

I thought that one canister filling of 2000 units (so 20 uses) should be enough to eradicate one large patch of fungus. I can't really tell how the gas will spread by only looking at the code though, so I don't know when it would be considered overpowered. This thing shouldn't be the end-all anti-fungus tool.

You could also alter the time here. The MINUTES(30) is the average time it takes for the field to decay by 1 density.

You need to have separate check for furniture. Otherwise when a fungal terrain has a non-fungal furniture, it will be destroyed too.

What if you've crossed a fungal threshold like mycus or marloss? Shouldn't it be doing extra damage/poison to you?
