Impromptu Races 1.8c

This script greatly benefits from Faster AI Drivers's effects.
Consider installing that mod if you're going to try Impromptu Races to get the best experience.

Traffic variety mods would also be a good idea to install, so you have different cars to race against.

This script lets you race anyone in the GTA V world. You see a nice car you want to race against? Do a burnout near it and challenge its driver!

You will be able to decide the starting and finishing points, simply go to the starting point and wait for your opponent. If you have a waypoint set, that will be the finish line. If not, the game will pick a random place ahead.

The latest version includes bets! You can now make bets with the challenged driver! Depending on the vehicle you have and theirs, they can bet high, low or not at all. The AI actually gains the money bet! This can be useful if you want to take it back. You can either challenge them again and betting higher (they will have more money so they will allow higher bets) or, you know, you can just kill him.

Visual C++
NativeUI 1.5

Put "ImpromptuRaces.dll" and "impromptu_races.ini inside the Grand Theft Auto V/Scripts folder.

To start a race, do a burnout / honk near a vehicle.

------ "BUGS" ------
No matter how many times you challenge a driver, he will have money, due to the script giving them more money if they don't have enough to bet again.

------ CHANGELOG ------

- Drastically improved Brake AI helper, the AI cars will now actually brake instead of magic stopping them.
- Improved AI Helpers in general, granting more general stability to the AI cars.

- Fixed incompatiblity with Drift On Demand.

- Changed max betting to 2.000$ Only Supercars allow for this, lower tier cars have the bet capped to something lower.
- Added various AI helpers to make the races more fair.
- Added a Nitro ability for the NPCs, with some tweaks to allow them use it inteligently.
They will only use nitro if you have Realistic Nitro or TurboSystemV installed (auto-detected).

    @GlobalHawk_MSI Yeah, I've just updated Street Races. Both scripts have now the same stability behavior.

    @Stampede Check the scripthookdotnet log, see if it mentions any error regarding "ImpromptuRaces".

    @Eddlm anyway you can make a roll racing mode?
    As in triggering the AI drivers to just take off from you in rolling traffic with a hotkey???
    Just as if you rear end them enough and hit the horn some will speed off away from you

    Great mod but how do you stop a race?

    this really needs a way to cancel the race in case you mistakenly challenged someone etc... or how about just driving away and ignoring the guy cancels it?

    @Trucktheusa just start somewhere and set a waypoint which will be the finish line, but remember AI do not know that the stunt map is there

    @Eddlm Can you add an option for the ai to use the nitro or not to use

    Does the races work like NFS when you get a prompt to start and in order to when you have to stay in front of that person for a number of secs/minute

    Brilliant mod, but i'm wondering if there could be any way to make it more compatible with KillaTomate's RealisticDrivingV - perhaps some way of enabling AI race opponents to cheat with improved grip or something?

    I've tried simply raising the global braking forces for all vehicles, but without raising the traction too (which would totally ruin the handling mod), they simply brake too late regardless, over-cooking every turn.

    Given that the AI's racing viability depends on the R* handling defaults - especially grip, it seems - a temporary traction boost for opponents during the race could be the simplest solution..

    @MrVibrating Agreed AI is horrible at breaking with any handling mod.
    When things start to get good the AI crashes thier car and usually die or roll off a hill or cliff.
    I also wouldn't mind helpers for them when it comes to cornering and braking.
    Just don't bother acceleration and top speed.
    Since I like to race against the handling lines I create and benchmark performance specs

    @rastakilla ..similar to what i do - customise cars using a trainer, then *race against them.

    *ie. pick my way through their trail of destruction then rubberneck as they go up in flames..

    S'all good tho..

    @MrVibrating Ah you too yes??
    Check out the thread I made about an AI Recorder for GTAV.

    OMG i think you may have found the last and final mod i'd ever need..

    Circumventing the limits of AI entirely, and racing against your own 'ghost' replays?

    I already have multimonitor, headtracking, full direct car control and detailed FFB wheel via ikt and InfamaousSabre's mods... but it just means i have to race crap cars against faster ones for any competition. This would be the ideal solution, i could race supercars against each other with human precision... how cool would that be?

    Just thought of a temporary workaround, for now - gonna restore default handling to most of the DLC cars that i never drive anyway, just for something to race against..

    @MrVibrating I play GTA V in
    3D Vision
    IKT Manual Transmission
    Fast AI Drivers
    Simcade Handling
    Inverse Power
    FOV Mod
    Impromptu Races
    Better Street Races
    Drag Race Meets

    With this precise setup I actually enjoy racing in GTAV in 3D more than Forza Horizion 3
    I had stumbled upon that AI Recorder a couple years back in GTAIV.
    I actually tuned the AI files to 100 accurately playback my recordings to the T.
    Even drifting as you can see in the video.
    It worked great for roll racing on the highway and also doing vehicle fly bys in tunnels with modded engine sounds in GTAIV.

    I will do the same use default handling and copy paste the handlings lines for the cars I wanna race with. As long as you keep Fast AI Drivers to knock off the top speed cap on AI racers on straights you should be good.
    Or you can just experiment with brake force values since that is the main issue AI has driving these modded handling lines.
    Also I'm using an older version of impromptu races without any AI helpers because I like to do acceleration test me with wheel/manual transmission setup vs AI shifting directly based off my handling values.

    I've only got half those mods installed so looking up the others now, cheers for the heads up..

    Would like to try 3D by only have 60 Hz screens.. using a 2*3 array via a pair of Matrox TH2G's, F430 wheel and pedals, TrackIR via FreePIE, faster AI drivers, IKT Manny Tranny, Inverse Power, Custom Steering, Flawless for FoV, Impromptu Races, Enhanced Taxi Missions, + various trainers and speedos etc. Looking forward to playing this in VR one day, must be pretty boss in 3D tho..!

    @MrVibrating Yea I own 3D Vision and Occulus Rift.....I play it in 1440p 3D which is beautiful the car mods look amazing especially interiors at night lit up speedos.

    As for VR ehhhh....you have to use VorpX which isn't a good native experience.
    It looks like crap honestly
    Now VR in Assetto Corsa and Project Cars is amazing.

    When I do a burnout and press W+S, impromptu races starts. The flag icon appears and it sets a car to races with me. Can I make the toggle to be only the horn, E?
