How Do Ragdoll Physics Work In Video Games?

Ragdoll physics is what happens when character models flop around after you shoot or hit them in games. Here's how it all actually works.

How could you do a history of ragdoll without mentioning the Euphoria engine and GTA IV? That game's physics was an amazing pioneer in blended ragdoll; with how NPCs could seamlessly enter a semi-ragdoll, semi-animation state in such a way that tries to preserve themselves. For example, bumping into an NPC with a car will have him/her extend their arms out and limp backwards a bit, trying to absorb the energy and keep themselves from being hit. Characters hit with physics objects would tumble and stumble, trying to keep upright. If you were drunk, you were perpetually put in such a semi-ragdoll state so that you could trip over curbs, cans, etc. Being hurled through the air or falling down a staircase also had the player curl up into a fetal position and put their hands over their heads in an effort to keep their heads from injury, whereas a dead body would simply go limp. There's so many little things that it's just amazing.

I love that type of video, very instructive. Could you made talk about history of heightmap in videogame to render terrain ? I'm developper and i am very interested about that kind of info, I've found no video about that. which are the first video game to use heightmap (Margic carpet ? Rogue squadron ?)

I would be more interesting if an enemy or even yourself died randomly.
4:44 if you wanna know it this is euphoria,a ragdoll physics engine that has realistic interactions,instead of bones falling off.

please write down games names as we see their gameplay in the video. thanks

I've never really been a fan of ragdoll physics, something about it just looks really fake, it's like watching an actor in a scene that gets swapped out for a crash dummy you cannot help but notice the change.

Watching this to figure out why it’s so hard for there to be rag doll physics in For Honor. Slice someone’s head off and they go to their knees? Come the fuck on...

pretty good summary for someone who doesn't know how to make games. would like to see more from that UE4 demonstration

I think you explained forward kinematics the first time, not inverse kinematics

My first game with ragdoll physics was Dave Mirra and we rented it at a sleepover and we just kept crashing the whole night laughing our asses off uncontrollably watching him let his bones loose flying through the air and then getting caught on one side rails spinning uncontrollably.

Anyone else get satisfaction from tossing enemies from high places and watching them falling down a mountainside, cliff, etc.

Using bones doeant mean your using inverse kinematics. Inverse kinematics is a way to "procedurally" animate the bones. You have have bones without ik animation.

Overgrowth has a great reaaaaally great ragdoll animations, at least for me

I don't why but as a kid I've always had a fascination with ragdoll physics ever since I played republic commando on the Xbox. I used to think it was so cool how the droids went all limp when you killed them, and didn't die with the same static animation over and over.

McGeezle (1 year ago)
Blended ragdolls in games like CoD are pathetic. What the fuck is the point in making a handful of shitty repetitive death animations and forcing them over the infinite possibilities of the physics? I cannot believe CoD is STILL fucking doing it to this day, AND they're the SAME animations as 2007

It's not inverse Kinematics it's a skeletal mesh (bones) and the stair food placement in Dark Souls Is with IK bones otherwise this was a Great Video :)

Its the Euphoria guy.the guy who has smartness that allows him to move his bones even thought he's a ragdoll!

meatball99 I thing it looks more like a media and also it don't look too much like the bipedal robots from Halo 4 that also look like MGS 4 Gecko's

"Do nothing animation" -> the common term is "Idle animations". Do not confuse the children, teach the proper terms
JaNa Joy Ramos (8 months ago)
Do you know what is the meaning of idle??? verb 1. (of a person) spend time doing nothing; be idle. "four men were idling outside the shop" synonyms: do nothing, be inactive, vegetate, take it easy, mark time, twiddle one's thumbs, kill time, languish, laze, lounge, loll, loaf, loiter; More

0:37 Isn't it how 'DO' rag doll physics work in video games not how 'DOSE'. Didn't wanna be that guy but I hate Americans getting the English language wrong
Andrey Aunmag (1 year ago)
There need more realistic physics. There's so little games that have cool engines. I'd made similar video how should a perfect game works too in my channel.

Not entirely true. Inverse kinematics and ragdoll are different things. But they can work together. Let me explain. Inverse kinematics is editing a non physics animation with code. It fires a trace from the knee, or the foot downwards to check where the ground is and then it edits the pose of a character depending on the result. No physics is needed to achieve this. Ragdoll is a set of physical bodies with mass and shape (capsules, spheres, boxes, convex meshes) stick to the character's skeleton that are connected with constraints, hinges. When it fires up it falls down dragging the skeleton and the character with it. Now, what GTA 4 and GTA 5 uses euphoria, what TruCloudGaming said. Euphoria is a toolset of creating blended animation and physics. That is, when a ragdoll fires the source animation is taken into account as a result to which a physical ragdoll should strive for. So, ragdoll actually uses motors, applies angular and linear motion to the bodies in a way to achieve the pose an animation has at the moment. So, it's actually a 100% ragdoll with motor forces applied to the physical bodies. And this also can be used with inverse kinematics. An state of the character's skeleton has it's pose altered using code, and this animation is taken into account in the motor system of a physically driven ragdoll. *flies away*

Tomb Raider Legend and Tomb Raider Anniversary make pretty good uses of Ragdoll physics. Tomb Raider Anniversary does anyway.
