As part of a mod I'm working on, I'm trying to make a dwarven cannon, and it has to be epic. But I still have a few questions, plus it doesn't work like I want it to be: I want cannonbals to tear straight trough limbs, and, well, a dwarf shouldn't survive a shot at the torso at point-blank range either... What I've got so far:

[ITEM_WEAPON:ITEM_WEAPON_CANNON]
[NAME:cannon:cannons]
[SIZE:5000] (Will this make it very heavy, and thus slow down cannoneers?)
[SKILL:HAMMER] (Is this necessary? There is no melee attack possible with a cannon.)
[RANGED:CROSSBOW:CANNONBALL] (I guess I could use bowman skill here, but that's just a minor tweak.)
[SHOOT_FORCE:10000]
[SHOOT_MAXVEL:100]
[TWO_HANDED:0]
[MINIMUM_SIZE:15000]
[MATERIAL_SIZE:10]

[ITEM_AMMO:ITEM_AMMO_CANNONBALLS]
[NAME:cannonball:cannonballs]
[CLASS:CANNONBALL]
[SIZE:250] (This is 5 times  a bolt)
[ATTACK:BLUNT:500:10000:smash:smashes:NO_SUB:2000]

So, I have a cannon that has 10 times the force of a crossbow to propell 5 times as heavy projectiles, why doesn't it work right?

[TheDancinZerg]

Is it just not lethal enough for you or what seems to be the problem?

[Warlord255]

It may be the projectile is too heavy.

[EagleV]

Well, yes, it's not lethal enough, not even with slate cannonballs. I mostly get bruises. What I want is realism, and especially awesome and bloody realism . I don't get what is wrong, I made it extremely strong already (or so I thought).

Plus I'd like to know if a SKILL:HAMMER is necessary.

I'll try with a lighter projectile.

EDIT: first lighter cannonball tore apart the guts... Much better! Thanks!

Blunt will mostly break arms that it hits.  If you want it to chop things off, make it an EDGE attack.  You can also give weapons more than one attack now, so you could make it
[ATTACK:BLUNT:500:10000:smash:smashes:NO_SUB:2000]
[ATTACK:EDGE:500:10000:smash:smashes:NO_SUB:2000]
[ATTACK:EDGE:500:10000:smash:smashes:NO_SUB:2000]
for example, which is a cannonball that is twice as likely to slice through an arm as it is to break the arm.

Maxvel of 100 is the same as the bow and crossbow, which, historically, shot things at about 150-180 feet per second with historical weight war arrows/quarrels.  A cannon should be more in the range of, oh, 600 feet per second minimum (a modern .45 shoots at 850 fps).  I have no idea what the maxvel units correspond to, but quadrupling it would be a good start.

I also do not know the scale of the shoot_force units, but black powder burns at about 5,000 to 25,000 PSI.  Decide what caliber you want your cannon to be (near as I can figure from the raws, 200 size units = 1 pound when made from steel or iron, so your cannonballs are 1 pound 4 oz., which corresponds to a 1.8" caliber when made from iron), figure out the cross-sectional area of the barrel, then multiply by the pressure you want.  1.8" caliber and 5,000 PSI = 12,700 pounds of shootforce, but like I said, I don't know the units.  However, longbows and hand-spanned crossbows tended to be 100 to 150 pounds, so a cannon should have a shootforce of about 100x that of a bow or crossbow.

Isn't having a semi-physics-based engine great?

[EagleV]

Physics

Wow, this is great! Thanks! Where did you find this?

[Arrkhal]

Just some historical knowledge, plus my own modding ventures.

Though, I just tested a cannon that was 100x the shootforce of the Xbow and 8x the max velocity, and it didn't seem to do much.

I'm guessing the physics engine needs some debugging.
