Handling API doesn't work for some vanilla vehicles

[xxshady]

Description of the problem

Handling API doesn't working not only for custom vehicles (#1173), but also for some vanilla too, e.g. blista2, blista, issi2.

If you try to change some values directly on the vehicle object using vehicle.handling it's just won't work. When you try to get alt.HandlingData instance with passed vehicle.handling.handlingNameHash it says "model doesn't exist" (already fixed)

Some notes:

• These cars are front wheel drive
• vehicle.handling.acceleration initial value is always 0 for them
• It's not a bug from latest gta update (see comment https://github.com/altmp/altv-issues/issues/1173#issuecomment-1048057994)

Reproduction steps

1. Spawn blista vehicle

2. Try to change some handling

   alt.Player.local.vehicle.handling.acceleration = -100 // nothing changes

// UPD: this was fixed in js module

alt.HandlingData.getForHandlingName(alt.hash("blista")) // that works, though
alt.HandlingData.getForHandlingName(alt.Player.local.vehicle.handling.handlingNameHash) // ~~error: model doesn't exist~~

Expected behaviour

Handling API should work for these vehicles.

@mrgharabaghi there is no difference in that

[mrgharabaghi]

I have a list of vehicles that get the model doesn't exist error with the below snippet.

alt.HandlingData.getForHandlingName(alt.hash('blista2'));

Updated list.txt

@mrgharabaghi do you have no errors for issi2, blista?

[mrgharabaghi]

I don't have any error with blista. In fact, issi2 handling id is issi. There is no issi2 handling id in GTA V official files. Take a look at this: https://discord.com/channels/371265202378899476/748927139927031910/1003208332171034626

I thought your list was a vehicle model names

[xxshady]

I think then vehicle.handling.handlingNameHash is wrong for these problematic vehicles For example vehicle model: blista handlingNameHash should be alt.hash('blista') (as you can see here) but it is negative number for some reason

[xxshady]

Even then alt.HandlingData.getForHandlingName(alt.hash("blista")).acceleration = -100 doesn't change anything, and i tried to restream vehicle

[mrgharabaghi]

In handling.meta, acceleration doesn't exist and I don't know alt:V devs how made this. Maybe the problem of blista is related to this (alt:V internal acceleration value).

[mrgharabaghi]

These values (Official GTA V handling.meta) works for blista without any problem. mass - brakeForce - handBrakeForce - initialDriveGears

// blista == Handing ID
let hand = alt.HandlingData.getForHandlingName(alt.hash('blista'));
hand.mass = 1200;
hand.brakeForce = 0.001;
hand.handBrakeForce = 0.002;

// Needs fresh instance
hand.initialDriveGears = 3;

From what I've checked it doesn't load for these vehicles:

asea2
bison2
bison3
burrito5
cavalcade
cavalcade2
emperor3
mesa3
rancherxl2
rancher // I guess that's handling name and not vehicle model
sadler2
surfer2
tornado3
faction2
moonbeam2

Bump. This is a really big issue for us. We can't develop any custom handlings for default cars due to this and related issues. Any streaming or Handling API calls don't work correctly on AltV. @DurtyFree recommended us to push this issue.

@xxshady

As alt:V 16.2.5 says, vehicle.handling.acceleration is deprecated.

HandlingData.acceleration is deprecated and will be removed in future versions. Consider using HandlingData.driveBiasRear instead

You can use handling.driveBiasFront and handling.driveBiasRear without calling setupTransmission(). I tested this for blista and issi2, works fine.

And as I said in here and here, don't forgot to call setupTransmission() for initialDriveGears.

Time to close the issue.

[mrgharabaghi]

alt.on('enteredVehicle', (vehicle) => {
    vehicle.handling.driveBiasFront = 100;
    vehicle.handling.driveBiasRear = 0;
    vehicle.handling.initialDriveGears = 2;
    vehicle.setupTransmission();
});
