Part Transmission Function - Fexcraft/FVTM GitHub Wiki

# Function Overview
Name: TransmissionFunction
Function: marks the part as Transmission and stores transmission related values
From FVTM: yes

The Transmission Function allows you to set a part as Vehicle Transmission.
If you want your vehicle to work in the BasicSystem it needs a Transmission installed!

Example config:

{
    "__comment": "Part JSON file.",
    "Function": {
    	"id": "fvtm:transmission",
    	"gear_ratios": [ -3, 0, 3, 2, 1, 0.5 ],
    	"automatic": false,
    	"throttle_ratios_up": [ 0.35, 0.5, 0.75 ],
    	"throttle_ratios_down": [ 0.25, 0.4, 0.6 ],
    	"efficiency": 0.7,
    	"shift_speed": 40
    }
}

Here an overview of the available fields:

• id - the id of the function, it is fvtm:transmission
• gear_ratios - optional, custom gear ratios, no limit, please specify
  from highest (reverse) gear to highest (forward) gear, including "0" (neutral)
• efficiency - optional, transmission efficiency, default 0.7
• automatic - optional, if this transmission is automatic, default false

All bellow are for when the transmission is automatic:

• throttle_ratios_up - optional, json array with 3 values
  throttle-to-rpm ratio based on which auto-gear-shifting is shifting UP,
  • first value is for throttle bellow 30%
  • second value is for throttle bellow 70%
  • third value is for throttle above 70%
• throttle_ratios_down - optional, json array with 3 values
  throttle-to-rpm ratio based on which auto-gear-shifting is shifting DOWN,
  • first value is for throttle bellow 30%
  • second value is for throttle bellow 70%
  • third value is for throttle above 70%
• shift_speed - optional, interval between auto-gear-shift attempts, default 40
