Ragdolls - Creation, Transitioning to, and Optimization | Unity Tutorial

Learn the creation workflow for Ragdolls in Unity, how to toggle between an Animator and Ragdoll, and think through some optimization ideas when you have a large number of potential ragdolls in your game!

Ragdolls are a hugely popular mechanic in games that add, usually a funny mechanic into your game. What they always do though, is allow you to have models go limp and flop around procedurally!

While the tool we look at for auto-attaching Colliders, Rigidbodies, and CharacterJoints to the Transform "bones" of our 3d model, you can manually add these and have any model go into a Ragdoll by following the same process we followed to set up the hands and feet!

Hi if I leave the Animator On the collisions with the ragdoll colliders don't work well, they are very buggy... do you know how to fix this problem and use the same colliders in order to shoot and kill the zombie while the animator is On?

[Ignaciodev]

This video was absolutely great, thank you so much!!

[audemkay]

This is the best ragdoll tutorial I've seen. I've never been fully satisfied with my previous implementations. Thanks for the great video!

[ronigleydsonvilasnovas]

I needed a Ragdoll tutorial like this, one with all its special tips that make all the difference

[regys]

What a video, this makes everything clear AF!

[TimeFlierGames]

No way! I just started using your videos a couple days ago to help with my new VR zombie game (demo on my channel) and we're using the same free asset :)

finally a replacement for Brackey's, thanks for your help!

If your character's joints are stretching and moving in odd ways when being animated, make sure to set every rigid body to kinematic and then set kinematic to false when going into ragdoll

[CleanDay]

Truly a fantastic tutorial. Thank you for concise, fast, clean, and accurate information. Subbed and will be watching all your other videos :D

[realinfinux]

You can fix the head by manually adding a neck joint between the torso and the head. 😊

Is it possible to add ragdoll (just on death) to enemies in existing unity games (Turbo Overkill)?

[OndrejL]

as the saying goes: the devil is in the details. and those cruicial details presented here are missing in most of the other tutorials ive seen. thx chief

Hi Liam, , if im using unity's build up character controller, how can I dissable and enable ragdolls?

[Dehakuzo]

Any tips for the ragdoll>animator transition? Specifically with getting the positions lined up, and maybe even smoothening the transition so it doesn't snap.

For the positions... The ragdoll doesn't carry the game objects position, so if it gets blown away 10 meters, and then the animator is turned back on, it snaps back into it's original position, instead of it's new position.

As for the smoothing... Yeah, it's an instant snap, any ideas on how to transition from ragdoll to animator smoothly?

[TwoFahOfficial]

When I activates the animator again mai character was teleported to old position

[KonradGM]

... how did you made the 3 buttons at top left xD ? i often see unity debug buttons with this graphic but i was never able to find how to make those

[EliasArnn]

How would i ragdoll only the legs but not the upper body?

[KonradGM]

I got curious, is it possible to blend between Animation and ragdoll? By certain interpolation maybe mixed with weight strength for animation?

[milizfs]

there is a problem now the ragdoll enabler doesnt exist
