IV Released C++ Script Hook

[pinky]

Is there some way to check if a vehicle exists(not model)? I'm asking this, because of my Car Spawner. I added the DLC bikes to the spawn list, but if someone without the DLC mod spawns any of them, it crashes.

 

I *think* checking for the models won't help, because HasModelLoaded returns true, since the model files are there, but not in the default.ide.

I was thinking if there was a way to apply another one of the existing bikes handling to them instead of using the .ide as it causes other problems in the game if you add the vehicle.ide or any of the .ide files to be exact. You end up with random map object spawning and sometimes crashes in worst cases.

having trouble to get DisplayTextWithLiteralString to display dynamic information.

Such as u32and f32 values.

I was trying to format a string and convert it to a char but not much luck.

Has someone found a way?

[the hubster]

someone want to explain to me on how to Spawn a Vehicle and change your character, I'd like to play as Roman

? Example code for spawning a vehicle and changing character are included with the source.

[L0uNGeR]

How would I do this in C++?

 

function BeepOn()   PushInt(3)   CallNative("PREVIEW_RINGTONE")   Wait(1300)   CallNative("STOP_PREVIEW_RINGTONE")end

 

Thanks

Doesn't explain

 

...Unnecessary long code...

 

Yes it does

 

   m_SkinModel = MODEL_IG_JOHNNYBIKER;  RequestModel(m_SkinModel);  // Change our state so that we can change skin when available  m_State = StateChangeSkin;......................case StateChangeSkin: // Change the player skin when its available{ if (HasModelLoaded(m_SkinModel)) {  OutputDebugString(L"Skin model available... spawning it!\n");  u32 playerIndex = ConvertIntToPlayerIndex(GetPlayerId());  ChangePlayerModel(playerIndex, m_SkinModel);...........

 

 

That is for player model.

Ok this is out of my head, check it first!

 

Add these to your Scripting.h

 

 

static void PreviewRingtone(u32 tone) { NativeInvoke::Invoke<scriptVoid>("PREVIEW_RINGTONE", tone);}static void StopPreviewRingtone() { NativeInvoke::Invoke<scriptVoid>("PREVIEW_RINGTONE");}

 

 

Then you can use then in your code.

 

PreviewRingTone(3);Sleep(1500) // C++ wait command if im correct (google it). Although Sleeps in Tick isnt coolStopPreviewRingtone();

Yah I know how to put the natives in my code, but

 

Although Sleeps in Tick isnt cool

That's the problem.

Use a timer... something like:

 

 

switch( m_State ){  case StateDefault:     if (someCheck)     {        PreviewRingTone(3);        SetTimerA(0);        m_State = StateBeep;     }     break;  case StateBeep:     if (TimerA() > 1500)     {        StopPreviewRingtone();        m_State = StateDefault;     }     break;  }

 

 

Maybe I'll get around to implementing a context switching solution for working with Wait(...) etc.

So,How To Use Display Text?

[L0uNGeR]

Ah thnx for the reply aru.

I have nearly put everything I had in LUA into C++ now.

All but the things that require Wait(), since it's kinda tricky.

 

I don't dream in C++ yet, but I did create my own files and a class.

But when it comes to certain things, I must go back to the RunTick() and do stuff like this:

 

       if(TimerA() > 720 || TimerB() > 1300)  // TimerA() = LouNGeRCrap::BeepOff()              StopPreviewRingtone();         // TimerB() = LouNGeRCrap::BeepOn()

 

 

How would I do stuff that needs a lot of waits, like this:

 

// Gently upApplyForceToPed(c, 1, 0.0, 0.0, 4.0, 0.0, 0.0, 0.0, 7, 1, 1, 1)Wait(100)ApplyForceToPed(c, 1, 0.0, 0.0, 4.0, 0.0, 0.0, 0.0, 7, 1, 1, 1)Wait(100)ApplyForceToPed(c, 1, 0.0, 0.0, 4.0, 0.0, 0.0, 0.0, 7, 1, 1, 1)Wait(100)ApplyForceToPed(c, 1, 0.0, 0.0, 4.0, 0.0, 0.0, 0.0, 7, 1, 1, 1)Wait(100)ApplyForceToPed(c, 1, 0.0, 0.0, 4.0, 0.0, 0.0, 0.0, 7, 1, 1, 1)// Wait a bitWait(700)// Smash downApplyForceToPed(c, 1, 0.0, 0.0, -20.0, 0.0, 0.0, 0.0, 7, 1, 1, 1)

 

 

(yes this code does what you see in the YT video)

I also have all my stuff from Lua (alice) into this hook. It still has to crash, which is pretty impressive, alice sometimes crashed on me (and always the first time when launching GTAIV).

 

 

All my stuff except for one

 

I would like to write the char's coordinates on keypress to a file, I know how to get them, but I'm not sure how to output them.

 

I googled, and found a piece of code that would write something to a file, which indeed works.

 

 

ofstream myfile;  myfile.open ("Coords.txt");  myfile << "Writing this to a file.\n";  myfile.close();

 

 

Now, the question would be, how to write the float values from this into this file:

 

 

Char c; 	 	u32 playerIndex = ConvertIntToPlayerIndex(GetPlayerId()); 	GetPlayerChar(playerIndex, &c); 	f32 x,y,z; 	GetCharCoordinates(c, &x, &y, &z);

 

 

Any help would be appreciated.

 

 

Okay, I now know how, but it replaces whatever is there, each time I press the button, I would like it to append not replace.

@sjaak327: I'm trying to do the same, but with a nice filewriting code.

I doesn't give any compiler errors/warnings, yet the game crashes when I press the button.

Here's a snip:

 

 

void LouNGeRCrap::Log(char text) {       FILE *pFile;       errno_t err;       if( (err = fopen_s(&pFile, "LouNGeRCrap.log", "a+")) == 0 ) {               fprintf(pFile, "%s\n", text);       }       fclose(pFile);}void LouNGeRCrap::LogPlayerCoords() {       Char p = PlayerChar();       char buff;       f32 x, y, z;       GetCharCoordinates(p, &x, &y, &z);       sprintf_s(&buff, 70, "%f, %f, %f", x, y, z);       Log(buff);}

 

 

fprintf works fine when I put some static string in the place of "text".

"Log(char text)" is probably wrong.

 

NOTE: "a+" for fopen_s = Opens for reading and appending; the appending operation includes the removal of the EOF marker before new data is written to the file and the EOF marker is restored after writing is complete; creates the file first if it doesn't exist.

 

 

Thanks, that would come with the models' textures as well?

I'm pretty sure it does, I don't think you can spawn a existing model without it's textures.

"fprintf" works fine when I put some static string in the place of "text".

"Log(char text)"  is probably wrong.

This is the code that I'm using now:

 

 

else if ((GetAsyncKeyState(VK_NEXT) & 1) != 0) 	{ 	Char c; 	 	u32 playerIndex = ConvertIntToPlayerIndex(GetPlayerId()); 	GetPlayerChar(playerIndex, &c); 	f32 x,y,z; 	GetCharCoordinates(c, &x, &y, &z); 	 	using namespace std;  	ofstream myfile ("Coords.txt", ios::app);        myfile <<"x=" <<x; 	myfile <<"\n"; 	myfile <<"y=" <<y;  	myfile <<"\n"; 	myfile <<"z=" <<z; 	myfile <<"\n"; 	myfile.close();    	DisplayTextWithLiteralString(0.5f, 0.25f, "STRING", "Coordinates Written !");

 

 

This works fine, when I press Pagedown, the coordinates are written to the file, I'm now searching for a way to write this to the end of the file, affectively apending the file instead of writing it at the beginning. Apparently seekp might be able to do the trick, I'm trying now.

 

Edit: it works, the following code will get the x,y and z coordinates to the file specified with append.

 

it will put the coordinates in the file in just the way I prefer:

 

x=-606

y=-753

z=65.9908

I am not sure how to get the "Char *pChar".

*pChar is a pointer, call the function and add "&" to the variable.

 

Char myNewRandomChar;CreateRandomChar(0.0, 0.0, 0.0, &myNewRandomChar);

 

myNewRandomChar now contains (hopefully) data, that is of type Char (not Char as in text but Char as a person ofcourse)

Aru: how do i declare a var of type Car in my .h file?

 

If i do:

 

Private: Scripting::Car myCar;

 

 

I get error C2039: 'Car' : is not a member of 'Scripting'. Although Car is shown in the autocompletion... Wierd.

[GAK]

I think you should add

#include "Scripting.h"

or

#include "ScriptingTypes.h"

at the beginning of your code

Yeah, it now works. But im not allowed to make a vector of cars somehow, i get massive errors. Anyway, time for beer

Can someone give me a pointer as to how to call GetCarColours, (c, colour1, colour2) how do I declare the last two parms ?

but I'm having trouble with the two colour parms.

Just declare them as normal, in this case, ints.

 

int color1, color2;

 

Then when using them in the native, slap an ampersand (&) in front of them (&color1). When you use whatever to read the values to another native (like SET_CAR_COLOURS, without the ampersand), they will be filled with the info you "got" previously.

[aceship]

how to use this

if (IsCharInAnyCar© = 1)

is this right?

if in lua

 

Pushint(PLAYER_CHAR)

Callnative(is_char_in_any_car)

If ((Getintresult)=1)

Like this, How to use like that in c++

 

Edit : Nothing, Just a secret

New version: 0.2.0. Download on first post.

 

Features:

 

- Solution reorganized... ScriptHook now compiles as a .lib, and the samples are in separate projects that compile to a .dll linking against that .lib. Full source is still included.

 

- New NativeFiberThread base class lets you do linear programming instead of tick-based programming. This should allow you to use things like Wait(). See the SampleCustomFiber project for more details.

 

- Reorganized Scripting types... Char is now Ped (like it should be), and Car is now Vehicle (like it should be), and PlayerIndex is a real type now (Player) instead of just a u32. You don't have to replace the declarations in your existing code if you're porting to the new version of the hook... they should still compile as is.

 

- Cleaned up new native functions in Scripting.h totaling about 650 natives now (still lots more to go). Each sample project has its own Scripting.h allowing me to update the main Scripting.h going forward without messing up your own declarations.

 

- Added basic logging functionality. See the sample projects for more information if you would like to consume this in your own code.

 

-------

 

@Intosia

 

#include <vector>

#include "ScriptingTypes.h"

 

then:

 

std::vector<scripting::Car> vectorOfCars;

 

@L0uNGeR... Try the NativeFiberThread thing in 0.2.0 for your code with lots of Wait()s

 

@Sacky... I thought about it for a bit... I think an approach like this should do:

 

1. Change NativeInvoke::Invoke(ch *, NativeContext *) to store the name/context somewhere, and then go into a loop until the code is executed.

 

2. Create a NativeThread that properly invokes the stored name/context (if available) and sets a flag for the parent thread to exit the loop.

 

Its somewhat hacky, and it blocks the caller thread but thats probably the best approach.

Woooohh, PURE AWESOMENESS Thanks Aru!

[aceship]

Im not using the 0.2 now, Its make your script messed up(If you are editing the script.h) when you are building it and not done yet, I think you must use it AFTER your Script done(If you are editing the script.h), am i right?

[klanly]

I tested the 0.2.0, SampleCustomFiber.asi. It seems all function would become unavailable when I reload the game from gamesaves. Will you fix this?

And I'm getting the following error:

 

Scripting::ChangeCarColour' : cannot convert parameter 2 from 'int' to 'Scripting::eColour and

Conversion to enumeration type requires an explicit cast (static_cast, C-style cast or function-style cast)

 

So This must have to do with the enumeration in scriptingenums.h. I guess I have two options, either do that enumeration, or change the native to not include enumeration.
