Yeah, I'll continue with things as they are. It's not as bad as it looks.

[Angle]

Alright, so I'm using CM for size measurements, and g/cm^3 for density. How do I measure the impact yield, impact fracture, etc? probably newtons or centinewtons, but shouldn't I take the thickness of the object into account? Also I have no idea where to find those values.

Use DF values. Ask Urist Da Vinci for how to use them.

Aaargh this is complicated! I'm thinking I might just use a simpler damage system, most of the combat code will be in the raws, so people can edit it anyway. Right now, I think it'll just determine the damage based on a formula depending on the attack type.

Thrusting Damage = Raw Damage / Contact Area

Cutting Damage = Raw Damage * Sharpness

Piercing Damage = (Raw Damage * Sharpness) / Contact Area

or something like that. Then the material will have resistance to each type of damage, or perhaps multiple resistances (Fracture and Bending, say) and I can go from there.

[Sergarr]

"Cutting Damage = Raw Damage * Sharpness"

Is not dependent on contact area?

Also you forgot Blunt damage. Which also needs to go through flexible armor like it was not there.

[Angle]

Not for cutting, I don't think. Does it matter how long a sword is when it cuts you? Not really.

Thrusting Damage basically is Blunt Damage.

[Angle]

Alright, so that covers offensive stats, at least momentarily. For defenseive stats, I think I need something for each of the following:

Being Dented or Squished

Being Shattered

Being Cut

Being Pierced

and of course, resistances and such for the various forms of energy. I'm going to leave those out for a bit though, and focus on physical forms of damage.

Anything you think I'm missing?

[flabort]

Being torn? Like paper or hot aluminum?
Or is that part of shattered.

Once you finish focusing on the physical forms, you may want to start with how other forms of energy affect material's physical resistances. Such as fire, heat, making a material less resistant to everything but shattered. Or freezing, cold, making the material less resistant to being shattered.

[Angle]

Hmm. That'd be dependent on a things tensile strength, and it's flexibility. You could tear a paper wall by hitting it and making it flex to to the point where you overcome it's tensile strength. I think I'll hold off on adding that kind of functionality, and just not add any materials that would likely involve it.

As for the second, I have code that can do that, though I havent actually done it yet. That's what my ItemMod's are for.

[Angle]

Now that I think about it, should I just have each material get it's own script for determining damage? Cause I could totally do that.

Edit: Yup I did it. Now I just need to finish the bloody scripts...

So, for n materials you'll need n*(n-1)/2 scripts? This could lead to some problems with adding new materials.

[Angle]

Well, no, I've been using single scripts for multiple materials. Right now I have three: One for metals, one for flesh, and one for brittle materials like bone or minerals.

[flabort]

That math doesn't feel right, Sergarr.
For one material, that's (1*0/2)=0 scripts. For two materials, that's (2*1/2)=1 script. For three, that's (3*2/2)= three scripts. Then 6 for 4, 10 for 5, etc. Yeah, you have exponential growth, but in the lower ranges it doesn't feel right.

[Angle]

I don't see how you have exponential growth. At best it's linear, when each material gets it's own script. There's only one script for determining offensive properties.  Here, do you guys want me to release another demo so you can see the potential of the system I currently have in place?

[Sergarr]

That math doesn't feel right, Sergarr.
For one material, that's (1*0/2)=0 scripts. For two materials, that's (2*1/2)=1 script. For three, that's (3*2/2)= three scripts. Then 6 for 4, 10 for 5, etc. Yeah, you have exponential growth, but in the lower ranges it doesn't feel right.

Oh right, I was wrong.

It's n*(n+1)/2. And it is not exponential, it is quadratic.
