Shipyard
Shipbuilding
The handle_build_ship function is at 0x0052A360.
Build Capabilities
A shipyard's current quality level of each ship type is stored in the town's current ship quality level array, indexed by the ship type.
The u8 values range from 0 to 3.
HP and Capacity
A ship's HP and capacity depend on the respective quality level.
At 0x00673838 there is a table that holds the structure base values for every ship type and quality level:
| Type | Quality Level 0 | Quality Level 1 | Quality Level 2 | Quality Level 3 |
|---|---|---|---|---|
| Snaikka | 15 | 19 | 23 | 25 |
| Craier | 28 | 31 | 34 | 35 |
| Cog | 45 | 48 | 52 | 55 |
| Hulk | 55 | 59 | 65 | 70 |
To the structure base value an unknown value is added, which appears to be always zero. The resulting structure value is capped at the value of QL 3.
HP and Capacity scale linearly with the structure value:
capacity = 2000 * structure_base_value
health = 2800 * structure_base_value
For a QL 3 hulk, this yields the expected capacity of 140.000 (700 barrels).
Resources and Price
The calculate_ship_build_cost function is at 0x0052B2C0.
The shipyard charges a utilization markup that increases when the shipyard is in use, and decreases if it is not.
At 0x0066DEB0 there is a table that contains the requirements of every ship type and quality level, capped at QL 2 (QL 3 does not increase cost):
| Type | QL | Timber | Cloth | Hemp | Pitch | Iron Goods | Unknown | Base Price | Unknown |
|---|---|---|---|---|---|---|---|---|---|
| Snaikka | 0 | 7 | 3 | 3 | 3 | 20 | 17 | 7,650 | 11,414 |
| Snaikka | 1 | 9 | 3 | 3 | 3 | 20 | 20 | 8,200 | 12,074 |
| Snaikka | 2 | 11 | 3 | 3 | 3 | 20 | 24 | 8,800 | 12,784 |
| Craier | 0 | 12 | 5 | 5 | 5 | 30 | 29 | 18,260 | 24,450 |

| Cog | 2 | 22 | 3 | 4 | 4 | 40 | 53 | 17,490 | 23,446 |
| Hulk | 0 | 30 | 16 | 16 | 8 | 50 | 58 | 22,968 | 34,442 |
| Hulk | 1 | 33 | 16 | 16 | 8 | 50 | 64 | 23,040 | 34,579 |
| Hulk | 2 | 36 | 16 | 16 | 8 | 50 | 69 | 24,840 | 36,664 |
Wares are consumed as listed in the table. The ship price is calculated as follows:
def structure_markup(structure):
if structure < 20:
return 900
if structure < 30:
return 840
if structure < 40:
return 780
if structure < 50:
return 720
if structure < 60:
return 660
else:
return 600
price = base_price
+ structure_markup(structure_base_value)
+ utilization_markup
