=== Callbacks (12, 22) ===
−
==Running cost base (0A) and factor (09)==
  
  +
For ships, the following [[callbacks]] have to be enabled by setting the corresponding bit in properties 12 and 22 (certain other, not as frequently used callbacks are available without setting a bit here):
−  
−
TTD calculates all costs by multiplying a 48-bit base amount with an 8-bit factor. &nbsp;The base amount is changed according to inflation, whereas the factor remains constant.
  
−  
−
For the running costs of road vehicles, the following base amounts are available:

−  
−
Theoretically, you could use pointers to other [[BaseCosts|base amounts]] available in TTD, but these are the numbers TTD uses for road vehicles.
  
−  
−
==Cost factor (11)==
  
−  
−
The cost factor is a bit-coded value which determines how expensive a vehicle is. The table below gives you some values to use for finding the right price for your vehicles.

Bit is the bit you have to set, you do this by adding all the values for all the bits. Variable 0C value is what variable 0C will be set to, for checking it in the VarAction2 for callbacks.
−
==Realistic acceleration properties (13, 14, 15)==
  
   
  +
=== Refit cost (13) ===
−
TTDP uses these properties only if road vehicles are set to realistic acceleration in the NewCurveAndMountainHandling switch. They are ignored otherwise.
  
   
  +
Refit cost, using 1/32 of the default refit cost base. This property can be overridden by callback 15E.
−
OpenTTD uses these properties always, if they are defined and gives the speed defined here precedence over the one defined in property 08.
  
   
  +
{{ottdp|1.2|no|ottdrev=r23087}} If the refit cost factor is set to zero and bit 4 of the miscellaneous flags (17) is set, auto-refitting is allowed.
−
Using property 15 to set the speed, it is possible to achieve speeds larger than 80 mph (127 km/h), to which property 08 is limited. When setting property 15, always set property 08 as well, so that the vehicle works reasonably well whether realistic acceleration is turned on or off. If property 15 is not set, the value from property 08 is used instead.

This is a bit mask, with the following bits:

Bit is the bit you have to set, you do this by adding all the values for all the bits. Variable 0C value is what variable 0C will be set to, for checking it in the variational action 2 for callbacks.
  
−  
−
==Coefficient of tractive effort (18)==
  
−  
−
This cofficient sets what fraction of the vehicle weight is equal to the maximum tractive effort. &nbsp;This includes the effect of having some unpowered axles, as well as the coefficient of friction that is available.
  
−  
−
For a value of FF, the tractive effort is equal to the vehicle weight, for 80, it is half, and so on. &nbsp;If not set, a default of 4C is used, for a fraction of 0.30, corresponding to Wadh=W and a coefficient of friction of 0.30, which is the value used by the patch before 2.0.1 alpha 19.
  
−  
−
==Coefficient of air drag (19)==
  
−  
−
This property sets the air drag coefficient c2 used for the realistic acceleration model, from 01 (no airdrag) to FF (most air drag) in arbitrary units. &nbsp;00 means to use the default value that depends on the top speed (to simulate the fact that high-speed engines are more streamlined).
  
−  
−
The default values are the following:
  
−  
−

For higher speeds, the series is continued in the same manner.
  
   
  +
Set the vehicle introduction date, in days since the year 0. This takes account of leap years; dividable by 4, but not 100 unless 400. A start date of 1920-01-01 is obtained with a value of 701265 (51 B3 0A 00). This property must be set after property 00 to take effect.
−
Air drag in Newtons will then be c2*v*v with v in m/s, although it is probably futile to attempt to make c2 a realistic number due to the lack of TTd's consistent scaling. &nbsp;If a vehicle doesn't reach its historical top speed, you might try setting prop. 19 one or two higher than the default above, otherwise it's probably a good idea to leave it at the default.

Descriptions

Callbacks (12, 22)

For ships, the following callbacks have to be enabled by setting the corresponding bit in properties 12 and 22 (certain other, not as frequently used callbacks are available without setting a bit here):

Bit Value Variable 0C value Callback
2 4 12 Load amount
3 8 15 Set refitted capacity
5 20 19 show a suffix after the cargo type name
6 40 2D Select color mapping for vehicle
7 80 33 Sound effect callbacks
8 100 161 Supported by OpenTTD 1414Engine name
9 200 163 Supported by OpenTTD 15 (gd2496b6ec4)15 Not supported by TTDPatchCustom refit

Bit is the bit you have to set, you do this by adding all the values for all the bits. Variable 0C value is what variable 0C will be set to, for checking it in the VarAction2 for callbacks.

Refit cost (13)

Refit cost, using 1/32 of the default refit cost base. This property can be overridden by callback 15E.

Supported by OpenTTD 1.2 (r23087)1.2 Not supported by TTDPatch If the refit cost factor is set to zero and bit 4 of the miscellaneous flags (17) is set, auto-refitting is allowed.

Miscellaneous flags (17)
