[TUTORIAL] Modifying Vehicle Handling

If you would like to change the handling/colors for a specific vehicle, follow these steps to find the car you want. Each section begins with "DVO3", if your cursor does not land on a "DVO3" header you did something wrong. Colors are easily noticeable and have "FF" in front of each value, the first paintjob has "8F" after the color code, and an "AA AA" separator with "FF" following shortly after.

Let me know if something is unclear. Click the image to enlarge (it's a bit large, didn't want to stretch the forum).

Any questions/comments, please post them here.

I have studied the tutorial but the question is: on which file change the value ? the B03 ?

Changes are made to the .BO3 files. You don't change any vehicle ID values except for the contents inside each of the "DVO3" file chunks. The colors, which is what people are mostly interested in, are towards the end of the DVO3 section and have "FF" in front of all of them, with "AA" as a separator and "8F" being the first paintjob.

The vehicle IDs you do not change, this is merely to navigate to the proper vehicle so you can change colors and stuff.

Nope, that's another tutorial. Sorry about the title, I changed it for hopefully the last time.

in istanbul.vvs i changed 4D (calita's car) to 4C (packer transport) but something didn't work right and changed it to police car.

so then i tried to rename istanbul.vvs to mission28.vvv but something screwed up and made all the cars invisible.
for taxi i don't know becuse i was so sleepy i couldnt remember :(

Oh cool. Swap the IDs and it should work, make sure there's no duplicates.

I see that you have 29 handlings/DVO3 found.
But in the miami, i've searched for every DVO3 string, and I found 34.

I just can't seem to find a code that makes the car go faster. If it is possible, can you point me out where it is based?

Unfortunately I do not fully understand BO3 files yet, I would need to do extensive investigating to see what controls vehicle speed.

Also, just to clarify, the 29 vehicles I listed in Miami do not reflect upon the number of DVO3 entries. Those IDs were taken from the VVS/VVV files. I have mentioned before in another thread that there are indeed more BO3 entries than there are cars. I have a feeling it's related to missions, since a VVV file can basically replace any car existing in the city. So think about a VVV file being used to create a special "mission-only" car with special characteristics that never spawns in traffic, but rather is used once in the mission by the AI. Pretty cool concept, really.

Did you do the swap in the miami_boat file ? You have to do this 2 times ( it's a values swap, 2D to 59 and 59 to 2D ).

Yep, make sure you're modifying the VVV file (VVS file should never be modified for simple vehicle swapping), and replace the "59" ID with 2D so the miami dade takes over the cigarette boats ID.

Sorry, but I can't understand. I want to replace the Go-Kart with the Monorail, but in Hex I'm very Noob :oops:
In fact, i can't understand what does mean "0x2B" and how it can be switched by "0x31". In Miami.vvs, at the headset 0x0000120 (Maybe it has more or less 0) it has a 2B, but if I search for "2B" I'll get a lot of them, so I don't know which I have to change. I tried to change that 2B for 31 but in "free Drive" I still have the Go-kart. Here is a video where did I found a Monorail instead of a normal Car
Sorry for my bad or very formal english, my 1st language is Spanish :oops:

Yes. Unfortunately I can't bring back the images who were managed with a dropbox account, for example.
So a lot of images will be missing in some topics.

I would really like to edit the brake bias for the vehicles. It's too far forward, you can't brake and turn without swapping ends! Has this function ever been discovered?
