The transmission_names unit class is used to define custom names for the gears of a transmission which are displayed in the UI and dashboard. Units of this type are usually defined in /def/vehicle/truck/<make.model>/transmission/*.sii or included from a Serialized Unit Includes (.sui) file and are usually nameless (the unit name is prefixed by a dot like .names or .foo.bar.names). They are assigned to a transmission accessory via the likewise-named transmission_names attribute of the accessory_transmission_data unit class.
Attributes
| Name | Type | Description |
|---|---|---|
| neutral | string | The gear name to be displayed when the transmission is in neutral. |
| reverse | string_array | The gear names to be displayed for reverse gears. The array indices correspond to those in the ratios_reverse attribute of the parent accessory_transmission_data unit. |
| forward | string_array | The gear names to be displayed for reverse gears. The array indices correspond to those in the ratios_forward attribute of the parent accessory_transmission_data unit. |
Note: While not a hard limit, it is advisable to keep the length of the gear names within three characters to avoid truncation, etc when displayed.
Example of an Embedded transmission_names Unit
The most typical usage is to embed the transmission_names within the same file as the accessory_transmission_data unit it belongs to. Here's an example of an 8LL (8 + 2 crawler gears) using custom gear names within the same SiiNunit.
/vehicle/truck/<foo.bar>/transmission/rt8ll.sii:
SiiNunit
{
accessory_transmission_data : rt8ll.foo.bar.transmission
{
name: "Example 8LL with custom gear names"
price: 8750
unlock: 0
icon: "transmission_generic"
transmission_names: .names
# RT-8908LL

# SQHD Differential Ratios: 3.70, 4.11, 4.33, 4.44, 4.63, 4.88, 5.29

}
Example of an Included transmission_names Unit
If a project is going to have a large number of transmissions using custom gear names and many will use the same custom gear names, it may be convenient to instead write a single .sui file with all unique instances of transmission_names and include it in the transmission definitions as needed. Let's say the earlier, embedded example is part of a larger set of transmissions using a handful of custom gear name sets.
/vehicle/truck/<foo.bar>/transmission/rt8ll.sii:
SiiNunit
{
accessory_transmission_data : rt8ll.foo.bar.transmission
{
name: "Example 8LL with custom gear names"
price: 8750
unlock: 0
icon: "transmission_generic"
transmission_names: .8ll.names
# RT-8908LL
# ---
# SQHD Differential Ratios: 3.70, 4.11, 4.33, 4.44, 4.63, 4.88, 5.29
differential_ratio: 4.11
# reverse gear
ratios_reverse[0]: -20.47
ratios_reverse[1]: -13.24
ratios_reverse[2]: -3.89
# forward gears
ratios_forward[0]: 19.58
ratios_forward[1]: 12.67
ratios_forward[2]: 8.39
ratios_forward[3]: 6.23
ratios_forward[4]: 4.58
ratios_forward[5]: 3.41
ratios_forward[6]: 2.46
ratios_forward[7]: 1.83
ratios_forward[8]: 1.35
ratios_forward[9]: 1.0
}
@include "gear_names.sui"
}
Note: Observe that the include occurs outside the scope of the accessory_transmission_data unit, but within the scope of the SiiNunit.
TIP: It is helpful in this case to use more descriptive (but still nameless) unit names for the transmission_names units so that it's still possible to intuit which unit is being assigned to the transmission definition without needing to open the included file.
/vehicle/truck/<foo.bar>/transmission/gear_names.sui:
transmission_names: .8ll.names
{
neutral: "N"
forward[0]: "LL"
forward[1]: "L"
forward[2]: "1"
forward[3]: "2"
forward[4]: "3"
forward[5]: "4"
forward[6]: "5"
forward[7]: "6"
forward[8]: "7"
forward[9]: "8"
reverse[0]: "RLL"
reverse[1]: "RL"
reverse[2]: "RH"
}
transmission_names: .other.names
{
# Other units can be defined in the same file as long as there are no namespace collisions!
}
Note: Because the transmission_names units are nameless, the "gear_names.sui" file can be included in many transmission definitions without fear of namespace collisions because nameless units only exist within the scope of the SiiNunit in which they are declared. However, nameless units within an SiiNunit must have unique names within that scope.
