Vehicles

[CapY]

Just some vehicles can be upgraded by spoilers, paintjob, etc,...

I want set it to be available on all vehicles

What functions do i need to do that ?

[JR10]

There is no function for that, that's something in GTA not MTA.

However you can use this function to get the vehicle compatible upgrades:

getVehicleCompatibleUpgrades

So i can't set all upgrades available for all vehicles ?

[JR10]

Yes, you can't.

You can't apply some upgrades in a way that would make GTA see them as upgrades, but you can create objects yourself and attach them to vehicle with these functions:

createObject 
attachElements
