Is there a compendium of NPC bones somewhere?

[HughJanus 244]

I would like to find out if NPCs are hit in certain spots, but dont know the int values of the bones.

Are they already known?

[HughJanus 244]

Maybe someone can help me if I explain what I'm trying to do: I am iterating through all the NPCs in the players surroundings and trying to check if they got hit in the leg. If they got hit in the leg, I flag the NPC. If an NPC got flagged, I compute a chance of stumbling for this NPC (so if he runs or sprints, there is a chance he stumbles and falls (I do that by setting the NPC to ragdoll and applying a light force to him, so he is pushed forward)).

 

Unfortunately until now I have not figured out how to check if an NPC got hit in the leg.

It might be easiest to run GET_PED_LAST_DAMAGE_BONE after you shoot a ped and take your own notes. For the bigger parts the results should hopefully be consistent enough. Would be great if you shared the list if you ever get around to creating one!

 

[HughJanus 244]

I might need your help there, bud :)

Because I have tried this already (and I wanted to get the int value shown on screen and not write it in a file), but I failed miserably^^

If you lend me a hand, I would be glad to create the list!

[LMS 674]

Sure, if you show me what you have so far I will see what I can do.

[HughJanus 244]

Its the DrawText method that kills me.

I have something like that:

std::string text = "Last Damaged Bone = ";
int actBone;
if (PED::GET_PED_LAST_DAMAGE_BONE(lastTarget, &actBone))
{
	text += std::to_string(actBone);
	DrawText(0.5, 0.5, text);
}

But the DrawText method (which wants two doubles and a string) is throwing an error - it says it wants a string^^

 

Edit: Wrong info - the DrawText wants two floats and a char* and I couldnt get the str to char*. Just remembered that.

 

Edit 2: I have now googled a bit and have another solution, but I think the text will only get displayed for the split second the player is shooting:

 

if (PED::IS_PED_SHOOTING(playerPed))
{
	Entity playerTarget;
	if (PLAYER::GET_ENTITY_PLAYER_IS_FREE_AIMING_AT(player, &playerTarget))
	{
		int actBone;
		std::string text = "Last Damaged Bone = ";
		if (PED::GET_PED_LAST_DAMAGE_BONE(playerTarget, &actBone))
		{
			text += std::to_string(actBone);
			int n = text.length();
			std::vector<int> temp(n + 1);
			char c[30];
			strcpy(c, text.c_str());
			DrawText(0.5, 0.5, c);
		}
	}
}

 

How would I be able to draw the text for longer? (if this works)

corrected the code snippet, added information

[LMS 674]

Could you also include your DrawText function? I am not sure where you got it from. Before calling _DRAW_TEXT you probably also need to "convert" your string to something the game accepts via _CREATE_VAR_STRING which essentially copies your string data to a game-controlled buffer. That should then show the text. As you have said correctly it will only occur for one frame though, so it would be best to loop this function.

Yesterday evening I had half an hour time and did it (i used a fixed character array as a global variable which is shown permanently and I always fill that with the latest bone the playerPed hit).

I will share the code of my solution on the weekend when I have more time.

 

Edit:

so heres the code (you can use it just like that if your project has all of alexander blades SDK stuff included):

void DrawText(float x, float y, char* str)
{
	UI::DRAW_TEXT(GAMEPLAY::CREATE_STRING(10, "LITERAL_STRING", str), x, y);
}

void main()
{
	bool modScriptState{ false };
	constexpr int toggleKey{ VK_F8 };
	int msgTime{ 0 };
	char c[40];
	int act = 99999;
	std::string text = "Last Damaged Bone = ";

	while (true)
	{
		if (IsKeyJustUp(toggleKey))
		{
			modScriptState = !modScriptState;
			msgTime = GetTickCount() + 3000;
		}

		if (modScriptState)
		{
			Player player = PLAYER::PLAYER_ID();
			Ped playerPed = PLAYER::PLAYER_PED_ID();

			if (WEAPON::IS_PED_WEAPON_READY_TO_SHOOT(playerPed))
			{
				strcpy(c, text.c_str());
				DrawText(0.4, 0.4, c);
			}
			else
			{
				if (PED::IS_PED_SHOOTING(playerPed))
				{
					Entity playerTarget;
					if (PLAYER::GET_ENTITY_PLAYER_IS_FREE_AIMING_AT(player, &playerTarget))
					{
						int actBone;
						if (PED::GET_PED_LAST_DAMAGE_BONE(playerTarget, &actBone))
						{
							act = actBone;
							text = "Last Damaged Bone = " + std::to_string(act);
							strcpy(c, text.c_str());
							DrawText(0.4, 0.4, c);
						}
					}
				}
			}
		}
		WAIT(0);
	}
}

void ScriptMain()
{
	srand(GetTickCount());
	main();
}

Good to see it's working now! Looking forward to your findings 🙂 I think for most of the bigger bones it will be quite simple but for others, such as the fingers, it could be trickier so I'd recommend starting with the more obvious ones.

[HughJanus 244]

At first I went to analyze the leg bones, but the results are weird.

Here are the IDs I noted when shooting those zones:

• bottom: 6884, 56200
• thighs: 65478
• knees: 6884, 55120
• lower legs: 43312
• ankles: 55120
• feet: 33646, 34606, 45454

I dont really know what to think of this, but it made the thing I wanted work. I check if the last hit bone is any of those and then mark the NPC and make them stumble. It works if I shoot their leg or foot anywhere.

Thanks for the research! That also confirms that they use different ids than on GTA V unfortunately. I had a closer look based on your findings and could map a few bones (mix of peds and horses it seems) and find more ids, although some names appear multiple times with different values.

How did you manage to pinpoint the IDs to certain bones when the IDs come up multiple times with different names?

What I also noticed is that the ID you got for the head (21030) I get when I shoot a dead body (no matter where) - maybe it returns the last damaged bone before death for me?

[LMS 674]

There are from some of the data files, but unfortunately are incomplete. I am not sure why there are multiple IDs for the same names, could be horse/ped again or something entirely unrelated. What happens when you shoot them in the leg until they die? Will it also return head afterwards?

[HughJanus 244]

You're right, it shows the last damaged bone before death.

Attached you find the .asi if you want to take a look for yourself (stripped away all the other stuff I am currently trying out - you can enable it with F9).

ShowLastDamagedBone.asi

[LMS 674]

Thanks! I fear we will not be able to find all bones using this way since there are so many, so hopefully we can find them in the data files.

[HughJanus 244]

I need some help.

I have been trying to apply force to certain bones, but they seem to vary for each NPC.

 

For example I tried to apply a force push to the right forearm (= 54187), when an NPC is down.

The sheriff in Valentine does work, but other NPC might be pushed in the left forearm, some even in the thigh,..

How can I make sure that I push every NPC in the right forearm - can I work with bone names somehow like this:

GET_ENTITY_BONE_INDEX_BY_NAME(Ped, "SKEL_R_Forearm");

 

Or does it need another name?

 

 

Edit: I just tried it with the bone names, but the result is the same. The Sheriff in Valentine keeps moving his arms, other NPCs mostly dont. Is that a known problem? How can it be solved?

Edited March 18, 2020 by HughJanus

[LMS 674]

I wonder if some peds just do not have these bones (or use different names). It's hard to say without the models. Can you get valid positions for the forearm bone on the other peds?

[HughJanus 244]

Havent tried. I was so frustrated after discovering that, that I moved on with something else^^

[HughJanus 244]

Has anyone figured out any other bones yet?

 

I think I found two more:

right upper arm 46065

left upper arm 37873

[jctwizard 0]

I came across this thread when searching about bones and I was wondering if either of you know is there a Native to change the scale/size of specific bones to say make the player head bigger?

[HughJanus 244]

@jctwizard I dont know, unfortunately.

 

I have the following bone IDs on NPCs I cant really tell which limb they belong to:

14283

22798

30226

34606

45454

54802

56200

 

Is there an easy way of finding out?

Do you by any chance know the ID of SKEL_R_Foot?

Or maybe even better, have a list of all the bones? :D
