Hi ! It's indeed specific to iracing, I never used this data as Simhub just pass automatically the data from the SDK with no post processing when it comes to GameRawData,
From what I see the values should be in thory like this (it's implicit due to the enum) :
irsdk_LROff=0,
irsdk_LRClear=1, // no cars around us.
irsdk_LRCarLeft=2, // there is a car to our left.
irsdk_LRCarRight=3, // there is a car to our right.
irsdk_LRCarLeftRight=4, // there are cars on each side.
irsdk_LR2CarsLeft=5, // there are two cars to our left.
irsdk_LR2CarsRight=6 // there are two cars to our right.
maybe the spotter is disabled ? From what i have read in the IR "docs" (changelogs
) it's intended to replicate the spotter calls.
