Firefighting
You can integrate your aircraft's own firefighting method with the Mission Hub. You will need to implement the 3D model and VFX yourself.
To interact with the mission system, Lvars are used. The specific implementation differs depending on which firefighting method your aircraft uses:
Lvars to set
MMH_COMPATIBILITY_FIREFIGHTING
Always set to 1
MMH_BAMBI_READY
Set to 1 when the bucket is ready to be used (i.e. slung under the helicopter)
MMH_BAMBI_FULL
Set this to 100 when the bucket has been filled
Lvars to read
MMH_BAMBI_FULL
Use this to show/hide water inside of the bucket.
0 = bucket empty 100 = bucket full
MMH_WATER_RELEASE
Use this to drive when your water drop vfx is active.
0 = No water being dropped 100 = Water being dropped
Lvars to set
MMH_COMPATIBILITY_FIREFIGHTING
Always set to 1
MMH_FIREFIGHTING_WATER_TANK
Always set to 1
MMH_BAMBI_READY
Set to 1 when the bucket is ready to be used (i.e. slung under the helicopter)
MMH_BAMBI_FULL
Set this to 100 when the bucket has been filled
Lvars to read
MMH_BAMBI_FULL
Use this to show/hide water inside of the bucket.
0 = bucket empty 100 = bucket full
MMH_WATER_RELEASE
Use this to drive when your water drop vfx is active.
0 = No water being dropped 100 = Water being dropped
For MSFS2024, you can make aircraft compatible with the mission hub by setting up the native water drop system. We monitor the following simvars:
LIQUID DROPPING SCOOP OPEN VALUE
LIQUID DROPPING TANK TOTAL WEIGHT
LIQUID DROPPING TANK TOTAL CAPACITY
LIQUID DROPPING TOTAL DROPPED FLOW
