I am planning a mod based on X-COM: ufo defense. I'm planning to do all of the aliens, their weapons, and their terror units. I will probably try and do the units from Terror From The Deep also. I probably won't do much past the basic anatomy since the new version promises to allow quite a few interesting things.

This thread also serves a few other purposes, the first is allowing you to suggest things for this mod. The other is me asking for help.

With these done you just need to make a new metal for the alloy, like so (template is the iron entry in inorganic_metal, unchanged except for the names):

   [BENDING_FRACTURE:310000]
   [BENDING_STRAIN_AT_YIELD:73]

With these in place, you need to add all of the new reactions to the alien entity. Look in entity_default and search for PERMITTED_REACTION to see where they go within an entity.

Code: [Select]
   [PERMITTED_REACTION:MAKE_ALIEN_ALLOY]
   [PERMITTED_REACTION:MAKE_ALIEN_ALLOY2]
   [PERMITTED_REACTION:MAKE_ALIEN_ALLOY3]

We need a research center!

First we take an alien artefact (dropped by random enemies) and decide in the building what would we like to get from it.

[flieroflight]

as dwarfs cant breath underwater, the tftd uns will need to be amphibious.
laser and plasma can probably be simulated by giving high temp ammo or syndromes

OMGWTFBBQ

[kerlc]

one thing: FINALLY!

[Kilroy the Grand]

I was wondering if I should make the terror units into cavern civilizations, so you can find them someplace other than seiges and ambushes. What do you guys think?

[kerlc]

i agree. there should be some left for HFS, though! 

[Kilroy the Grand]

I justed tested my Chryssalid in the arena. A no skill chryssalid, can easily kill a no skill dwarf in full iron armor. The chryssalid more or less opens the dwarf like a can of meat, then snip off body parts. Or it just injects venom into the dwarf, killing him almost instantly. I'm thinking instead of using the standard chitin, I should make it as strong as copper.


Also, at 20 tiles, 20 dwarves with crossbows and iron bolts couldn't bring a single one down, out of 20. When I tested a grandmaster crossbowdwarf, he ALMOST killed one, but the chryssalid closed the distance far to quickly, and lopped his head off. To be somewhat fair, I'm not letting the chryssalids have weapons or armor, because that would be crazy.

[StephanReiken]

Ha, with the next version you could get your Chryssalid mutating its targets into a Chryssalid or hopefully close.

Personally I'd throw them all into a single race as castes and have the only male/female caste as a machine creature. They are after all, all genetically created creatures iirc.

True, but wouldn't I have to set the litter size to something crazy big? To ensure that each alien wouldn't get out competed.

[kerlc]

*reads about the testing procedure*

glee!

*a muffled squeal*

[Kilroy the Grand]

I haven't modded in a lot of weapons, but I was thinking of making a material just below the ignition point of dwarves, but slighter higher for for all the aliens

[Alternatecash]

Oh, with the transforming syndromes, this will rapidly become made of win.

[Kilroy the Grand]

My thoughts exactly, this will make marksdwarves the only option.

Also, I modded in an "Raw Elerium" as a gem, since I couldn't think of a way to make invaders carry it with them... and I didn't want something silly happening like "elerium-115 maces".

To make most alien equipment you are going to need to refine elerium, then use it with Alien alloys (Which I haven't modded in). For laser rifles I was thinking of using clear glass and maybe aluminium... I could just make a reaction that spits out free ammo for it, but then I'd need to nerf the damage.

[StephanReiken]

If you do TFTD's races they can manufacture Zrbite unlike Elerium which can't be crafted. But if you are including TFTD you mine as well let the original races manufacture it too.

True I might as well! Now for the alein platic and alloy, I was thinking of making a reaction to turn any two metal into either of them. But I am sadly lacking in experience, might someone care to help?
