Hi, I am a computer science student working on a project to make gaming experience more realistic. I am currently stuck as I cant find a way to determine the body part where the bullet was shot. I need to locate the body part like hand, arm, head, chest etc as the bullet hits the user.

Do anyone knows if there are currently any mod available for a good FPS game like CS:GO, Battlefield, Call of duty etc. that can fulfill my requirement.

If currently not available, can anyone let me know if there is a possible way to develop such mod in these games.

I would be grateful if you can help me with these issues.

Thank you :)

So as in you want what to happen in the obituary there is a line that says player1 killed player2 hitlocationhere ? there are many mods that can make this happen. Cod 4 i couldnt tell ya but for cod uo it is as simple as adding the hitlocs to the obituary. If you need something to search for to help search call of duty 4 detailed obituary mod. You should find something that can help you.

i think CoD uses Hitbox for the character. i
found a multiPlayer_HitBoxModelChar in
CoD4/Model_export/base_character.
this model is added in asset manager
when you make an Xmodel, under
hitBoxModel, so my guess is that this is
how the game knows what part of the
character has been hit.
you can open this hitbox model in maya or
blender (need xmodel_export addon) and
you will see how it is made.
every part/bone has it's own name, like j_
head, j_neck, etc...

Thanks alot DrBiggzz, I am looking at it.

@trinkx, thanks for your detailed reply. But I cant figure out how using the model I can detect the part and send signal to a background process running.

If I can able to find that model, then how can I actually detect that this body part was hit, If I can print it in the console or anywhere from where I can detect easily. Can you help me with anything?

Thank you :)

that is done by scripting. you should find yourself a good modder, they do that kind of stuff in mods, when you make a headshot it displays a message on the screen. i'm a mapper so i don't need to script a lot.
hope you will find someone who knows how to do it.

in call of duty uo the hitlocations are as follows

Code:
getHitLocName(hitloc)
{
	switch(hitloc)
	{
		case "right_hand":	return "Right  Hand";
		case "left_hand":	return "Left Hand";
		case "right_arm_upper":	return "Right Upper Arm";
		case "right_arm_lower":	return "Right Forearm";
		case "left_arm_upper":	return "Left Upper Arm";
		case "left_arm_lower":	return "Left Forearm";
		case "head":		return "Head";
		case "neck":		return "Neck";
		case "right_foot":	return "Right Foot";
		case "left_foot":	return "Left Foot";
		case "right_leg_lower":	return "Right Lower Leg";
		case "left_leg_lower":	return "Left Lower Leg";
		case "right_leg_upper":	return "Right Upper Leg";
		case "left_leg_upper":	return "Left Upper Leg";
		case "torso_upper":	return "Upper Torso";
		case "torso_lower":	return "Lower Torso";
		case "none":		return "Pelvis";
		default:		return hitloc;
	}
}


^^now im not sure but i believe most cods use these body tags.^^


Code:
	// If the player was killed by a head shot, let players know it was a head shot kill
	if(sHitLoc == "head" && sMeansOfDeath != "MOD_MELEE")
		sMeansOfDeath = "MOD_HEAD_SHOT";
		
		
/*=============Added By C()D3R=============*/
//		Shows All That A Player Got A Headshot, Bash Kill Or Grenade/Satchel Kills. 
//		Sets The Points For A Headshot To Be Worth 2.
//		Shows All That A Player Committed Suicide.
	{
		if(sMeansOfDeath == "MOD_HEAD_SHOT")
		{
			attacker.score++;
			attacker.pers["headshots"]++;
			iprintlnbold(attacker.name + " ^3Scored A HeadShot On " + self.name + "");
			attacker iprintln("^1[^3HeadShot^1]^2Gained ^12^2Points!");
			maps\mp\antic\_antic::popHead(damageDir, damage);
		}


here is also a snippet of my headshots script this gives the player 2 points and displays that he scored a headshot.




there are easier ways to bring up the hitlocations but this is the method i currently use. I will post another method using the obituary to give detailed information about kills. once i script one up and get it working correctly.

You will have to make a mod that prints to a log file (using the logPrint() function) whenever a player is hit and then have your program monitor that log file.
The log file it prints to is set by the g_log setting, usually set to "games_mp.log" and located in the mod directory. You also need to make sure g_logSync is set to "2" so that data is written immediately.

Thanks alot guys, you guys are best people ^_^

Dr.Biggzz, your suggestion also helped, thats what actually I am looking for, when a person gets shot any where in the body, I want to locate where(body parts) the bullet was hit and print it to a file(or anything from which I can keep track of hits) and process it accordingly. What you suggested seems like what I am trying to do.

@Killer, your comment also helped me.

I am currently learning how to mod COD4 and will try to implement on your suggestions and will let you know. :)

I will let you know if any further supervision of yours is required. :)

Please let me know if there is anything else that could help me in this regards.

Thank you :)
