Hey guys, I've got a bit of a problem with a script I'm making. It doesnt seem to want to work. It compiles fine and i dont get any errors in the log, so i don't know what's going on.

Heres the code I've come up with:

CODE

using System; using System.Windows.Forms; using GTA; namespace DisabledAutoReverse {    public class DisabledReverse : Script    {        bool bEnabled = false;        Vehicle vMyVehicle;        public DisabledReverse()        {            Interval = 100;            this.KeyDown += new GTA.KeyEventHandler(DisabledReverse_KeyDown);            this.KeyUp += new GTA.KeyEventHandler(DisabledReverse_KeyUp);            this.Tick += new EventHandler(DisabledReverse_Tick);        }        public void DisabledReverse_Tick(object sender, EventArgs e)        {            if (bEnabled)            {                vMyVehicle.Speed = 0.0f;            }        }        public void DisabledReverse_KeyDown(object sender, GTA.KeyEventArgs e)        {            if (e.Key == Keys.S)            {                if (Player.Character.isInVehicle())                {                    vMyVehicle = Player.Character.CurrentVehicle;                    if (Exists(vMyVehicle))                    {                        if (vMyVehicle.Speed < 1.0f)                        {                            vMyVehicle.Speed = 0.0f;                            bEnabled = true;                        }                    }                }            }        }        public void DisabledReverse_KeyUp(object sender, GTA.KeyEventArgs e)        {            if (e.Key == Keys.S)            {                bEnabled = false;            }        }    } }

And could someone possibly explain to me how to use GameKey please?

Thanks.

It probably just jumps past 1f, try raising this limit or set it up different:

CODE

using System; using System.Windows.Forms; using GTA; namespace DisabledAutoReverse {   public class DisabledReverse : Script   {       bool bEnabled = false;       public DisabledReverse()       {           Interval = 100;           Tick += new EventHandler(DisabledReverse_Tick);       }       public void DisabledReverse_Tick(object sender, EventArgs e)       {            if (isKeyPressed(Keys.S)) bEnabled = true;            else bEnabled = false;                        // or use here >> .Speed = 0f;            if (Player.Character.isInVehicle()) Player.Character.CurrentVehicle.FreezePosition = bEnabled;            else bEnabled = false;        }    } };

The above way you don't need the Key*** events etc, just the tick and AFAIK it should stop you reversing.

[lindsayslorach]

Thanks for the reply, but my understanding of the code you've given, is that when i press S it will freeze the car in its current position?

I'm just having a bit of fun making this, but i was really after, when braking, it would brake like normal, and then come to a complete stop.
Then to reverse you would have to take your finger off S and press it again.

I know I probably should have specified that in the first post, sorry.

I'll try raising the check from < 1.0f to something higher.

Thanks.

Good luck with the script.

I'd be interested in something like this, although I would prefer to have a dedicated button for switching from 'drive' to 'reverse'. That would be cool.

[lindsayslorach]

Thats a very good idea, I might try to impliment that when i get this code running properly.

I've been testing a car mod, and I've noticed that when i get in a car, and try to reverse, it tries to stop me, so the script kinda works, just not in the intended way.

[AngryAmoeba]

Perhaps using isKeyPressed like in Donny's code would work better. It seems the vMyVehicle.Speed lines in the KeyDown procedure won't run if your speed is above 1.0f when you press S.

[Donny78]

I didn't even think of the breaking, I can see what you mean now and yes that would be a problem.

What about checking the velocity of the vehicle, if it's relative to it's angle then the y axis would have a positive value for driving forward and a negative for reversing so you could check the value and respond to it.

CODE

// bound keypress S custom {    Vector3 vel = Player.Character.CurrentVehicle.Velocity;    if (vel.Y < 0)    {        if (!DoublePressed)        {            Player.Character.CurrentVehicle.FreezePosition = true;            DoublePressed = true;        }        else        {            Player.Character.CurrentVehicle.FreezePosition = false;            DoublePressed = false;        }    }    else DoublePressed = false; }

Again that could be buggy though, if you get into a crash or something and try correcting it by reversing like when you're spinning out then it would freeze it but it's a base to work on.

[AngryAmoeba]

I thought of a way you might be able to implement a button to switch gears between drive and reverse.

I don't know the language you guys used (is it C#?), but I tried to put my idea into code. There might be syntax mistakes and that kind of thing... and I'm sure this could be optimized.

See below for updated code.

I like the idea of having a gear effect dude and yes it's c#.

Edit:

Is that on purpose the "== 0f" so it only works when you're static ?

[AngryAmoeba]

Yeah that's on purpose. If the car is moving and you press S, you don't want the car to be frozen. Instead, S will brake until the car stops, then it will freeze the car.

I also realize now that you should only be able to switch gears when the car is stopped.

EDIT: And now I've realized that this will probably break boats and helicopters.

Yeah good point, damn my brain isn't turned on today.

I'm not on my main computer so no IV to check it out but I do think the velocity check would be better as then you could directly check if it's reversing, this is ofcourse if it works how I think it does (negative velocity for reversing, y-), it would be much easier to code then:

CODE

public bool IsVehicleReversing(Vehicle vehicle) {    if (vehicle != null && vehicle.Exists())    {        if (vehicle.Velocity.Y < 0) return true;    }    return false; }

Then you can do stuff like:

CODE

// tick if (IsVehicleReversing(Player.Character.CurrentVehicle)) {    if (!isKeyPressed(Keys.Tab)) Player.Character.CurrentVehicle.FreezePosition = true;    else Player.Character.CurrentVehicle.FreezePosition = false; } else Player.Character.CurrentVehicle.FreezePosition = false;

[AngryAmoeba]

I did some testing, but I couldn't get .Velocity to work. I encountered several problems using .Speed as well.

Here's the best thing I could come up with. I discovered that using Player.CanControlCharacter = false instead of FreezePosition works better. But unfortunately, this conflicts with C06alt's First Person mod. When playing with that mod and CanControlCharacter is set to false, the camera switches from first-person to the hood cam.

If you don't play in First Person, this script is almost fully functional now. However, if you drive backwards and then spin around 180º, you don't have to switch gears to drive forward because your speed never drops below 1.0f. So a velocity check would be better, if I could just figure out how to get it to work right.

CODE

using System; using System.Windows.Forms; using GTA; public class ManualReverse : Script {    bool bFrozen = false;    bool bReverse = false;    public ManualReverse() {        Interval = 100;        Tick += new EventHandler(ManualReverse_Tick);        KeyDown += new GTA.KeyEventHandler(ManualReverse_KeyDown);    }    public void ManualReverse_Tick(object sender, EventArgs e) {        if (Player.Character.isSittingInVehicle()) {            if (Player.Character.CurrentVehicle.Speed < 1.0f) {                if (bReverse) {                    if (isKeyPressed(Keys.W)) freezeCar();                    else unfreezeCar();                }                else {                    if (isKeyPressed(Keys.S)) freezeCar();                    else unfreezeCar();                }            }        }        else if (bReverse) bReverse = false;    }    public void ManualReverse_KeyDown(object sender, GTA.KeyEventArgs e) {        if (e.Key == Keys.Tab && Player.Character.isSittingInVehicle()) {            if (Player.Character.CurrentVehicle.Speed > 1.0f) {                Game.DisplayText("Stop car to switch gears");            }            else {                bReverse = !bReverse;                if (bReverse) Game.DisplayText("Switched gears: REVERSE");                else Game.DisplayText("Switched gears: DRIVE");            }        }    }    public void freezeCar() {        if (bFrozen) return;        GTA.Native.Function.Call("SET_CAMERA_CONTROLS_DISABLED_WITH_PLAYER_CONTROLS", 0);        Player.CanControlCharacter = false;        bFrozen = true;        if (bReverse) Game.DisplayText("Switch gears to drive forward");        else Game.DisplayText("Switch gears to reverse");    }    public void unfreezeCar() {        if (!bFrozen) return;        GTA.Native.Function.Call("SET_CAMERA_CONTROLS_DISABLED_WITH_PLAYER_CONTROLS", 1);        Player.CanControlCharacter = true;        bFrozen = false;    } }

Hey, thanks for the replies guys!

Thanks for the code, AngryAmoeba! I'll give it a test soon.

Cheers.

Edit: Just tried the script, works like a charm, thanks!

[Hypertenzion]

Could one of you guys build the script for me (us)?

I can't seem to make it work when I try to make the dll file from the script in Visual Studio 2010?

[AngryAmoeba]

Hi, you can just copy the script code into Notepad and save it as ManualReverse.cs in the 'scripts' folder of the .NET scripthook. No compiling necessary.

Thx AngryAmoeba. I thought that method was only possible with VB scripts.

[Hypertenzion]

I can't seem to make it work.

I use Scripthookdotnet v1.7.1.4 + GTA Version 1.0.6.0

I created a file "Reversescript.cs", put it in the "Scripts" folder for .NET scripts and loaded it with this:

CODE

using System; using System.Windows.Forms; using GTA; public class ManualReverse : Script {   bool bFrozen = false;   bool bReverse = false;   public ManualReverse() {          Interval = 100;          Tick += new EventHandler(ManualReverse_Tick);          KeyDown += new GTA.KeyEventHandler(ManualReverse_KeyDown);   }   public void ManualReverse_Tick(object sender, EventArgs e) {       if (Player.Character.isSittingInVehicle()) {           if (Player.Character.CurrentVehicle.Speed < 1.0f) {               if (bReverse) {                   if (isKeyPressed(Keys.W)) freezeCar();                   else unfreezeCar();               }               else {                   if (isKeyPressed(Keys.S)) freezeCar();                   else unfreezeCar();               }           }       }       else if (bReverse) bReverse = false;   }   public void ManualReverse_KeyDown(object sender, GTA.KeyEventArgs e) {       if (e.Key == Keys.Tab && Player.Character.isSittingInVehicle()) {           if (Player.Character.CurrentVehicle.Speed > 1.0f) {               Game.DisplayText("Stop car to switch gears");           }           else {               bReverse = !bReverse;               if (bReverse) Game.DisplayText("Switched gears: REVERSE");               else Game.DisplayText("Switched gears: DRIVE");           }       }   }   public void freezeCar() {       if (bFrozen) return;       Player.CanControlCharacter = false;       bFrozen = true;       if (bReverse) Game.DisplayText("Switch gears to drive forward");       else Game.DisplayText("Switch gears to reverse");   }   public void unfreezeCar() {       if (!bFrozen) return;       Player.CanControlCharacter = true;       bFrozen = false;   } }

Hmm strange, I don't see the reverse script anywhere in your log.

Are you absolutely sure the file is named and located correctly? If so, I'm not sure what the problem could be... All I can think of is some kind of version conflict. I use version 1.7.1.6 of the scripthook and GTA4 1.0.4.0.

Neither do I?!
I am absolutely sure that I named it correctly and put it in the right folder.

The version conflict would be the best suggestion
I use 1.7.1.6, but Scripthook states that the version is 1.7.1.4. The author of Scripthook probably missed the "version" part in the output of the log

[AngryAmoeba]

Well, I'm not so sure about that. Here's my log file. You'll notice that it says version 1.7.1.6.
