Diverse Artillery Mod (DAM) for NTW. 13/4-2010 New version 1.4

[에바1호기]

The Diverse Artillery Mod version 1.4 is now released 13/4-2010.

This mod adds diverse Artillery units and changes existing units to give a more (IMO) realistic representation of Napoleonic era Artillery and also to diversify the different faction roosters. The mod is meant to be played on top a vanilla installation or among compatible mods. Therefore I try to construct it in a modular manner so it doesn’t overwrite unnecessary tables/files. That allows it to be easily included in mod compilations like the “Napoleon all in one mod” by ToonTotalWar.


In short I have:

• Adjusted projectiles table
• Implemented new projectiles.
• Increased distance for ½ chance hit.
• Added DAM Artillery units to the several factions roosters (quick battle and European/Coalition campaign)

Before release the build goes through a simple engineering test and files are under configuration control.

Changelog:

Version 1.0

1. Ranges for projectiles increased to more realistic values including Canister (12pdr=900/400). The bigger the barrel, the bigger propellant it has and thereby longer range. See http://napoleonistyka.atspace.com/artillery_tactics.htm for further information.
2. Velocity lowered to give more bouncing shots. Might be lowered to much, therefore feedback appreciated.
3. Number of Canister pellets adjusted to increment with munition size.
4. Damage model differentiated for Howitzers taking munition size into account.
5. Base reload time adjusted with 12pdr=60seconds as baseline. 6pdr. is thus 30seconds. Also See http://napoleonistyka.atspace.com/artillery_tactics.htm for further information.

Version 1.1: Test version only.

Version 1.2

1. Implemented 4-lber projectile.
2. Added 5 new units to French rooster:

• 4-lber Foot Art.
• Artillerie à Cheval‎ de la Garde Imperiale, Young Guard (4-lber Horse Art.)
• Artillerie à Cheval‎ de la Garde Imperiale, Old Guard (8-lber Horse Art.)
• Artillerie à Pied de la Garde Imperiale, Young Guard (4-lber Foot Art.)
• Artillerie à Pied de la Garde Imperiale, Old Guard (12-lber Foot Art.) All with unique properties/values.

Canister range decreased to 300meters due to gameplay issues.
Other minor adjustments to Projectile table.

Version 1.3 and 1.3.1

1. Implemented 3-lber cannon projectile.
2. Implemented 5.5” howitzer projectile.
3. Implemented 10-lber howitzer projectile.
4. Adjustments to projectile table.
5. Added 16 new units:

• 5.5-In Howitzer Foot Artillery, France
• 5.5-In Howitzer Horse Artillery, France
• 10-lber Unicorn Horse Artillery, Russia
• 10-lber Howitzer Foot Artillery, Austria
• 10-lber Howitzer Foot Artillery, Prussia
• 7-lber Howitzer Horse Artillery, Austria
• 7-lber Howitzer Horse Artillery, Prussia
• 6-lber Horse Artillery, Austria
• 3-lber Foot Artillery, Austria
• 3-lber Foot Artillery, Prussia
• 12-lber Foot Artillery, Britain
• 9-lber Horse Artillery, King's German Legion, Britain
• 5.5-In Howitzer Foot Artillery, King's German Legion, Britain
• 5.5-In Howitzer Horse Artillery, King's German Legion, Britain
• 9-lber Hanoverian Foot Artillery, Britain
• 6-lber Foot Artillery, King's German Legion, Britain
• All with unique properties/values.

Version 1.3.1 added. Based on 1.3 with Artillery missile half chance hit increased to 325 meters in "kv_rules" table giving a better accuracy at longer ranges.

New in current version 1.4:

Current version

Current Version 1.4

Projectile table reworked:

Round shot damage (Kinetic energy) now linked linear to projectile “mass” based on the formular for kinetic energy, under the assumption that projectile speed does influence the kinetic energy of a projectile in NTW game engine:

Projectile mass now correlated with cannon/howitzer bore diameter using this formula (rearange to isolate "r") to calculate the radius of a sphere (and ultimately calibre). The density of a cast-iron cannonball is approximated to 7.6g/cm3:

Using the formula gives the following values (rounded):

mass in Lb........diameter in Inches
3-lber............. 2,8
4-lber............. 3,0
6-lber............. 3,5
8-lber............. 3,8
9-lber............. 3,9
10-lber........... 4,1
12lber............ 4,4
18-lber........... 5,0
20-lber........... 5,2
24-lber........... 5,5
30-lber........... 6


So a 5 inch howitzer actually fires a projectile with the size of an 18-lber cannonball and a 6 inch with the same size as a 30-lber cannonball. I don’t think that is modelled correctly in Vanilla NTW and possibly also in other mods.

I have used these values to increase the lethality of explosive shells and explosion “size”. So prepare for more lethal howitzers.

Further projectile changes:

• missile_distance_for_half_chance_hit_artillery lowered to 290
• Reload times for every projectile changed based on weight and projectile complexity. Setting the fuse on an explosive shell requires some time by the loader.
• Number of pellets adjusted to source information values and due to howitzer barrel length their canister shots contain 33% less pellets (source information).
• Pellets are modelled as musket balls (distinction between small and large lead balls not possible in current table) and will inflict similar damage.
• Howitzer canister shot changed to low trajectory.
• Projectile ranges changed to source information values. Minimum explosive shot distance increased to 180meters.
• Projectile velocity values overhauled.
• Carcass and limestone damage differentiated. Limestone now more lethal.

New projectiles:

• 1-lber round shot.
• 20-lber Howitzer
• 14-lber Cannon
• 20-lber Cannon

New units:

• 1-pundige Amusetter, Danske Artilleri Brigade (quick firing 1-pounder cannon with a listed double reloading speed as a musket). Denmark
• 3-pundige kanoner, Danske Artilleri Brigade. 3-lber Denmark
• 6-pundige kanoner, Holstenske Artilleri Brigade. 6-lber Denmark
• 12-pundige kanoner, Norske Artilleri Brigade. 12-lber Denmark
• 10-pundige Haubitsere. 10-lber How. Denmark
• 20-pundige Haubitsere. 20-lber How. Denmark
• 3-pundige kanoner, Göta artilleriregemente. 3-lber Sweden
• 6-pundige kanoner, Svea artilleriregemente. 6-lber Sweden
• 12-pundige kanoner, Vendes artilleriregemente. 12-lber Sweden

• 5-In Howitzer Foot Artillery. Added Portugal
• 5.5-In Howitzer Foot Artillery. Added Portugal, Netherlands and U-Netherlands.
• Experimental Howitzer. Added Portugal, Spain, Netherlands and U-Netherlands. (Portugal and Spain will need better Howitzer Info cards in the future)
• 4-lber Foot Artillery. Added Spain,
• 8-lber Foot Artillery. Added Spain
• 6-In Howitzer Foot Artillery. Added Spain
• 6-lber. Added Spain
• 3-okka Foot Artillery. Ottomans 4-lber
• 5-okka Foot Artillery. Ottomans 6-lber
• 9-okka Foot Artillery. Ottomans 12-lber
• 11-okka Foot Artillery. Ottomans 14-lber
• 16-okka Foot Artillery. Ottomans 20-lber

What's next: Implementation of further Artillery units and rework of minor faction’s roosters. Possibly some retexturing and other changes.

The mod is mod packed and I noticed a wish in this forum for 8 cannons per unit on ultra settings so the 8 cannon/howitzer version will be maintained (NTW_DAM1.4_8).

I have intentionally not down scaled the number of Howitzers in a unit to 1 or 2 as it would probably not be worth wasting an army/stack slot on. Instead I have capped the units in the range from 1 to 8.

To play use the attached script file (Alter it if playing with 8 cannon file) and place the .pack file in "Data" folder. Attached .loc file shall also be placed in the Data folder for proper text in game. Remember to have only 1 .loc file in the folder.

It is based on the UPC1.8 file with last five lines being the DAM units.

Enjoy and have a great week.
