Intro

101 - How to set up a ship for Arma 3

What's the difference between a boat and a ship? Well, a ship is usually large enough to carry a boat. Subs are also called boats, regardless of size. :)

For Arma purposes, lets call boats anything shorter than 60m (the apparent geo lod limit of Arma) and ships over 60m. Subs are subs!

There are 2 approaches to ships and boats in Arma 3. Typically boats are modelled and implemented as "vehicles" where as ships historically have been implemented as "static" objects.

A few very brave modders have attempted to mix the two. USS Iowa (mod by AusSnipe73) - http://www.armaholic.com/page.php?id=27109 - defines a ship vehicle but then attaches many different static objects and turrets to the ship to build out a 270m long vessel.

Similar efforts have been used to attempt to get a driveable LHD (from Arma 2).

Comparison to A2/OA ships

  • PhysX support (ShipX, SubmarineX)
  • Improved penetration materials
  • More detailed Fire Geometry LODs
  • Improved tweakability of HitPoints LODs

Model requirements {p3d}

  • LODs (included in Arma 3 boat p3ds)
    • Fire Geo
    • View Geo
    • HitPoints
    • Land Contact
    • Memory
    • Physx
    • Bouyancy
    • Geo
    • View Cargo
    • View Pilot
    • View Gunner
    • Resolution LODs 1-8
    • ShadowVolume 0, 10, 1000, 1010
  • A new PhysX LOD
    • There needs to be a lod (4e13) consisting of convex components as simple as possible.
      • Requires the latest Arma 3 Tools to binarize
    • This lod should contain ship’s hull, and ...
  • Bouyancy LOD
  • Memory LOD
    • See Model.cfg for a list of memory points

About shipX and submarineX

New config parameters {config.cpp}

Base class is Ship. There are 4 child classes FloatingStructure_F, Ship_F, SmallShip and BigShip.

FloatingStructure_F uses simulation ShipX.

Submarine_01_F inherits from FloatingStructure_F but is defined as vehicleClass="submerged" and does not appear to be implemented as a "vehicle".

C_Boat_Civil_04_F inherits from FloatingStructure_F is defined as vehicleClass="submerged" and does appear to be implemented as a "vehicle" but you cannot interact with it (get in etc).

Boat_F inherits from Ship_F and is the basis of most of the "boats" in Arma 3.

Boat_Armed_01_base_F inherits from Boat_F and uses simulation shipX.

Boat_Civil_01_base_F inherits from Boat_F and uses simulation shipX.

Rubber_duck_base_F inherits from Boat_F and uses simulation shipX.

SDV_01_base_F inherits from Boat_F and uses simulation submarineX.

SDV_01_base_F is used as the basis for all SDVs in Arma 3.

Submarine and Ship Config Detail

Collins class submarine that uses submarinex simulation class:

http://www.freeuploadsite.com/uploads/13725721431.rar

There you have a working example.

Now, for the config:

The behaviour of the ship in the water does not depend anymore on the Landcontact points, but on the GEO and PHYSX LODs. The PHYSx LOD seems to represent the water displacement of the ship. If you put too much mass (a value over the displacement) the ship sinks. The PHYSx LOD must be similar in form and size, to the ship's hull. It must also follow the Geometry LOD rules (closed and convex) and must be composed of only one component (that's what BIS says in the VSB2 editing wiki)

GEO is very important. It has given me a lot of problems. You must balance the mass in all axis (plural axes? ) and keep the weight down so the ship doesn't turn and sinks. In subs it is specially important because it controls how it moves once submerged and how it mantains depth


Code: 

airCapacity = 1209600;

Quite important for submarines. Determines the time the crew inside the ship can be below the surface before dying suffocated for lack of air. It seems that when using class submarinex, the engine sets the crew as if they were below the water


Code: 

verticalTurnCoef = 20.2;

This line seems to control the speed for ascending/descending.

Code: 

waterSpeedFactor = 3.0;

No idea of what this does. I have tried a couple of values and I haven't seen changes

Code: 

periscopeDepth = 15.5;

This is the depth the sub mantains when you activate the "Mantain periscope Depth" Action. It is important to know that for big models (not a SDV sized submarine) that this depth DOES NOT coincide with the depth marker in the left upper corner of the screen

Code: 

idleRpm = 1000;

Selfexplaining

Code: 

redRpm = 4000;

Idem

Code: 

thrustDelay = 2;

Delay after we start executing a movement and the ship/submarine starts the actual movement


Code: 

simulation = "submarinex";

simulation = "shipx"; PHYSx simulation classes

Code: 

overSpeedBrakeCoef = 0.8;

Brake effectivity. If you follow VBS 2 explanations, this value is (overSpeedBrakeCoef*enginePower). The higher the value, the better it brakes

Code: 

enginePower = 3278;

Engine power in HPs

Code: 

engineShiftY = 2;

This lines tells where the engine applies the force related to the origin of the model. Esentially what one mus calculat is the distance in the vertical axis between the Y value of center of mass of the model and the Y Value of the propeller, waterjet or whaterver moves the shipcuando pegamos un acelerón y valores positivos que se hunda. Negative values tend to make the bow rise when you accelerate and positive values tend to make it dive

Code: 

waterLeakiness = 1000;

This parameter determines the quantity of water (M^3 x S) that will fill the volume of the PHYSx LOD per second. Tipically lower vaues for boats, higher for bigger ships. Modifies the sinking rate of a ship when this suffers damage.


Code: 

waterResistanceCoef = 0.01;

Represents the resistance if the hull. The higher the value the higher the resistance. This affects acceleration and maximum speed.

Code: 

waterLinearDampingCoefX = 10.0;

This value represents lateral movements produced by waves. Higher values will make the ship corner better and slide less to the sides.

Code: 

waterLinearDampingCoefY = 1.2;

This one represents vertical movements depending on the waves. Higher values will modify how much the ship sinks/goes down depending on the waves. It can also affect the flotation line mantaining the ame Ship mass. Higher values will also make a ship sink slower

Code: 

waterAngularDampingCoef = 8.0;

Smooth the angular movement in all axis, higher values will reduce swinging/swaying, but may cause strange behavior in turns/rolling over waves.


Code: 

rudderForceCoef = 12;
     rudderForceCoefAtMaxSpeed = 15;

How the rudder works. The higher the value the more the ship will turn, BUT the more it will incline when turning. Values to high could even make a ship turn upside down (and sink) when turning. If you are transporting non scripted vehicles the can easily fall if this value is set too high.

There are two values. The first one is for low speed (usually ships turn better when sailing faster than a certain speed) and the second one when going at MEDIUM or FAST speed.

Code: 

     memoryPointsLeftWaterEffect = "waterEffectR";
     memoryPointsRightWaterEffect = "waterEffectL";
     memoryPointsLeftEngineEffect = "EngineEffectL";
     memoryPointsRightEngineEffect = "EngineEffectR";

These are points in the memory LOD that represent the spawning points for water particle FX. The first ones represent bow FX, the last ones represent the foam generated by the engine propeller

Damage handling

Boats/Ships offer differing protection levels for themselves and crew inside, depending on place you hit them. Balancing damage is usually most time-consuming task for armored vehicles.

Basic config


		armor = 30;

		class Damage
		{
			tex[] = {};
			mat[] = {"A3\boat_F\Boat_Armed_01\data\Boat_Armed_01_ext.rvmat","A3\boat_F\Boat_Armed_01\data\Boat_Armed_01_ext_damage.rvmat","A3\boat_F\Boat_Armed_01\data\Boat_Armed_01_ext_destruct.rvmat","A3\boat_F\Boat_Armed_01\data\Boat_Armed_01_int.rvmat","A3\boat_F\Boat_Armed_01\data\Boat_Armed_01_int_damage.rvmat","A3\boat_F\Boat_Armed_01\data\Boat_Armed_01_int_destruct.rvmat","A3\boat_F\Boat_Armed_01\data\Boat_Armed_01_ctrls.rvmat","A3\boat_F\Boat_Armed_01\data\Boat_Armed_01_ctrls_damage.rvmat","A3\boat_F\Boat_Armed_01\data\Boat_Armed_01_ctrls_destruct.rvmat","A3\Static_F_Gamma\data\staticturret_01.rvmat","A3\Static_F_Gamma\data\StaticTurret_01_damage.rvmat","A3\Static_F_Gamma\data\StaticTurret_01_destruct.rvmat","A3\Static_F_Gamma\data\staticturret_02.rvmat","A3\Static_F_Gamma\data\StaticTurret_02_damage.rvmat","A3\Static_F_Gamma\data\StaticTurret_02_destruct.rvmat","a3\boat_f\Boat_Armed_01\data\Minigun.rvmat","A3\boat_f\Boat_Armed_01\data\Minigun_damage.rvmat","A3\boat_f\Boat_Armed_01\data\Minigun_destruct.rvmat","a3\boat_f\Boat_Armed_01\data\Minigun_Boat_Armed_01_add.rvmat","A3\boat_f\Boat_Armed_01\data\Minigun_Boat_Armed_01_add_damage.rvmat","A3\boat_f\Boat_Armed_01\data\Minigun_Boat_Armed_01_add_destruct.rvmat","a3\Data_F\Vehicles\Turret.rvmat","A3\Data_F\Vehicles\Turret_damage.rvmat","A3\Data_F\Vehicles\Turret_destruct.rvmat"};
		};

Armour plates setup

Hitpoints

Hitpoints represent weak points in structure of ships: turret servos, ammo storages, engine. They can also improve internal penetration handling.

Example from Boat_Armed_01_base_F 

class HitPoints
		{
			class HitBody
			{
				armor = 0.7;
				material = 50;
				name = "karoserie";
				visual = "zbytek";
				passThrough = 1;
			};
			class HitEngine
			{
				armor = 0.12;
				material = -1;
				name = "Engine";
				visual = "";
				passThrough = 1;
			};
			class HitTurret
			{
				armor = 0.7;
				material = -1;
				name = "otochlaven";
				visual = "otochlaven";
				passThrough = 1;
			};
		};

Hitpoint categories

There are 3 common hitpoint categories in Arma 3's vehicles:

  • HitHull, handling internal penetration - when damaged over 0.9, vehicle will explode.
  • HitEngine, handling damage of engine

Turrets have their own class HitPoints, coontaining info about how easy it is to damage given turret:

  • HitTurret, horizontal rotation
  • HitGun, vertical rotation - this should handle any event that renders tank guns inoperable, f.e. hit to servos

New attributes

Hitpoints gained two important config attributes in Arma 3:

  • radius, defining size of “hitpoint sphere” around each vertice in Hit Points LOD assigned to given hitpoint’s selection
  • explosionShielding, multiplying damage inflicted by indirect damage. The smaller it is, the less damage hitpoint will receive.

Internal damage

Internal damage is handled by HitHull class. When KE round penetrates the armor plates, it passes the damage to HitHull hitpoints array as seen in example model. The hitpoint vertices are set up in such way that the nearest distance between them equals RADIUS attribute in HitHull class, and they cannot be activated by rounds that fail to penetrate armor.

During implementation of internal damage handling it is important to tweak following attributes:

  • armor
  • explosionShielding
  • radius

If the results of config tweaking are not satisfying, consider adding greater detail to Hit Points and Fire Geometry LODs.
