Head Blend Data

Vespura · 2018-12-25T12:18:31.920Z

Iirc, it’s:

(int) dad shape
(int) mom shape
(int) third (unused) shape
(int) dad skin color
(int) mom skin color
(int) third (unused) skin color
(float) shape mix
(float) skin color mix
(float) third (unused) mix
(bool) isParent (usually false)

Ye, the first code I posted in my topic wasn’t working as I had the blends not changing and the head types were the same

Vespura · 2018-12-25T12:21:50.344Z

Also probably best to set the floats to 0.5 at first if you’re testing, otherwise you probably won’t notice changes if you set it to 0.0 or 1.0 and you only change dad or mom values.

If I remember to do this later I’ll update the reference with some more info.

Any idea on how GetPedHeadBlendData works?
Whenever I try it, all it returns is 1
Also tried passing a table for its second argument, but then I get an error expecting an integer.

You can’t use this in lua. You can only use it in javascript or using the C# API set in which I’ve made a function for this.

Do exports work over different languages?
So if I used the function using JS and created an export that would parse the gained data in JSON, would I be able to execute the export in a Lua script to get the data?

Vespura · 2018-12-26T16:45:52.630Z

Yes that would work. However, in JS, the floats will be packed floats. So you need to convert them to real floats before you can use them afaik.

alberto2345 · 2018-12-27T09:59:57.297Z

How would I go about doing this in JS?

This is what I have currently:

function blendData(shapeFirst, shapeSecond, shapeThird, skinFirst, skinSecond, skinThird, shapeMix, skinMix, thirdMix){
	this.shapeFirst = shapeFirst;
	this.shapeSecond = shapeSecond;
	this.shapeThird = shapeThird;
	this.skinFirst = skinFirst;
	this.skinSecond = skinSecond;
	this.skinThird = skinThird;
	this.shapeMix = shapeMix;
	this.skinMix = skinMix;
	this.thirdMix = thirdMix;
}


RegisterNetEvent("getHeadBlendDataJS")
on("getHeadBlendDataJS", () => {
	var headBlendData = GetPedHeadBlendData(GetPlayerPed(-1), new blendData());
	console.log(headBlendData);
});

I’m triggering the event in Lua just using a command.
All I get in the console is

[
   1,
   32,
]

Which 32 is the ID of my first shape of head, but it isn’t getting everything else.
I’ve never done this before so I’m not sure what I’m missing?

Take a look at this old code that I never ended up using in vMenu but it works just fine:

github.com

TomGrobbe/vMenu/blob/f7f37ccfb4ae00ae9235b99140b6e526e98abef0/vMenu/mp_ped_data.js

function Export_GetPedHeadBlendData() {
    var arr = new Uint32Array(new ArrayBuffer(10 * 8)); // int, int, int, int, int, int, float, float, float, bool
    Citizen.invokeNative("0x2746BD9D88C5C5D0", GetPlayerPed(-1), arr);
    return JSON.stringify(arr);
}

on('GetPedHeadBlendData', (cb) => {
    cb(Export_GetPedHeadBlendData());
});

alberto2345 · 2018-12-27T11:55:30.751Z

Thanks for the code.

I have tried to use it but all I get is 0 for the values.
Code:

function Export_GetPedHeadBlendData() {
    var arr = new Uint32Array(new ArrayBuffer(10 * 8)); // int, int, int, int, int, int, float, float, float, bool
    GetPedHeadBlendData(GetPlayerPed(-1), arr);
    return JSON.stringify(arr);
}

RegisterNetEvent("getHeadBlendDataJS")
on('getHeadBlendDataJS', (cb) => {
	var data = Export_GetPedHeadBlendData()
	console.log(data);
})

Output:

{"0":0,"1":0, etc all the way to "19":0}

I also tried changing it to 10 * 4 instead of 10 * 8 and 10 * 4 produces from 0 - 9 instead of 0 - 19 (as there is only 10 values to retrieve from GetPedHeadBlendData), and still same result with it only having 0’s.

I have made sure that my character has had some form of Head Blend data changed, so I know that it should be returning something.

Vespura · 2018-12-27T14:15:59.433Z

you need to use the snippet exactly like i did it. You can’t just call the native by name, you have to use invoke because it passes that array view directly. Like a pointer to a struct in c++.

alberto2345 · 2018-12-27T14:41:35.401Z

Vespura:

Citizen.invokeNative(“0x2746BD9D88C5C5D0”, GetPlayerPed(-1), arr);

Ok no problem.

So now the output I get seems to have a value in between that is always 0.
And the decimal numbers are not decimals, but very long integers. Is this what you meant by having to convert them to real floats? Or is this something different?
Here is a picture of my output. Top line is what my current head blend values are and bottom line is what was created in the array by the native.

Vespura · 2018-12-27T14:43:41.476Z

only look at the ‘even’ key/value pairs. (0, 2, 4, 6, etc). the other ones are just padding and unused.
those very long integers are indeed the packed floats i was talking about. If you want to use them like decimal numbers, you’ll need to find a way to unpack them. This is a lot easier in c# because the function I made just outputs a correct struct.

alberto2345 · 2018-12-27T15:25:22.496Z

I found that if you create another array that is of Float32Array, it will output the correct floats for the mix values.

At the end of the day, like you said, it will be easier and cleaner to use C#, however this method does work if you purely want a JS version.

function Export_GetPedHeadBlendData() {
    var arrForShape = new Uint32Array(new ArrayBuffer(10 * 8)); 
    var arrForMix = new Float32Array(new ArrayBuffer(10 * 8));

    Citizen.invokeNative("0x2746BD9D88C5C5D0", GetPlayerPed(-1), arrForShape);
    Citizen.invokeNative("0x2746BD9D88C5C5D0", GetPlayerPed(-1), arrForMix);

    return [arrForShape, arrForMix];
}

RegisterNetEvent("getHeadBlendDataJS")
on('getHeadBlendDataJS', (cb) => {
	var result = Export_GetPedHeadBlendData()
	console.log(result[0][0] + ", " + result[0][2] + ", " + result[0][4] + ", " + result[0][6] + ", " + result[0][8] + ", " + result[0][10]);
	console.log(result[1][12].toFixed(2) + ", " + result[1][14].toFixed(2) + ", " + result[1][16].toFixed(2));
})

Made a c# wrapper for it here:

Small C# export/event wrapper for GetPedHeadBlendData() Releases

Continuing the discussion from Head Blend Data: Just made a small c# ‘export’ wrapper for this: [image] Also works by using an event: [image] The export simply returns it, and the event requires you to use a callback function in which the data will be passed as an argument. It’ll be a table in lua, in c# it’ll just be a dynamic object, possibly an expando object or maybe the actual PedHeadBlendData struct, but i’m not sur…

alberto2345 · 2018-12-28T12:35:18.972Z

Very nice.

One thing I’ve noticed is it creates a jump in CPU latency. I think this is a current issue with C# scripts that is being investigated.

E.g. Current resource I have is 0.04 ms. Put the C# script in it and it jumps to 0.36 ms

Vespura · 2019-01-21T09:20:28.436Z

If that works then great, but when I asked the elements they said that strings would break like that. But if you’ve tested it and it works then that’s nice!

I did make a wrapper for it but I guess that’s not needed then.

What’s wrong with GetPedHeadBlendData?
I’m using this func for ~1 year, everything is fine.

function GetHeadBlendData()
  return Citizen.InvokeNative(0x2746BD9D88C5C5D0, PlayerPedId(), Citizen.PointerValueIntInitialized(0), Citizen.PointerValueIntInitialized(0), Citizen.PointerValueIntInitialized(0), Citizen.PointerValueIntInitialized(0), Citizen.PointerValueIntInitialized(0), Citizen.PointerValueIntInitialized(0), Citizen.PointerValueFloatInitialized(0), Citizen.PointerValueFloatInitialized(0), Citizen.PointerValueFloatInitialized(0))
end

local data = {GetHeadBlendData()}
local dadShape = data[1]

Probably this func can be simplified

samarium · 2019-01-21T10:09:52.013Z

that’d break if the internal layout for pointer values ever were to change however

JiminyKroket · 2022-04-10T04:16:44.558Z

The issue with GetPedHeadBlendData is that in Lua it returns one single value instead of an array/object/table whatever your language wants to consider them. Has there ever been any update on if this can or will be fixed? Really gonna suck having to have a .js or c# file for one single function, or iterating all the frameworks ped skin tables
