VRChat Avatar Dynamics Tutorial - Contacts

ko-fi.com/sippbox
With the avatar dynamics system of features, Contacts allow you to drive animations on your avatar when you or other players interact with them! This allows many features like grabbable objects, or having your avatar's face react when headpatted! This tutorial will show you how Contacts work, and also show you how to set up a high five particle effect using them!

Precise, detailed, and straight to the point. Your tutorials are always super helpful

[@koi7035]

Awesome tutorial. I love how concise your videos are. Thank you for the help! I look forward to more tutorials on this new cool feature.

[@3PeoplePlayVidya]

Thank you so much for putting in the effort to make these videos. Just started learning the basics, and this helps a lot.

[@X1erra]

I'm eager to get my own Quest one day to use with PCVR, and I'll be making the most of your tutorial! Thanks :)

[@Artorikus]

As always, excellent tutorials, clear and precise. Thanks for making this tutorials, please continue this way!

You are awesome my man. Wish I had this knowledge in my head like you do but atleast you share it so I can if I put in the work!

[@boneitch]

I can't believe how easy this was. Somehow, I looked at the documentation a year back and thought "meh, maybe later". Now I watched this video and literally screamed "Wait. That's IT??". Thank you so much!!

[@ajaxsakaraplayz4070]

I think the documentation is just a little in-depth

[@Ratboycure]

Such good information really well done thanks fella

[@purples1501]

amazing tutorial as always!! worth mentioning that the Motion Time in the animator's Blend Tree must be active for the value of the Proximity Contact Receivers to correspond dynamically along the dopesheet* of the desired animation. *Edited for vocab, thank you @Lhun!!

[@LhunVideo]

In the context of unity, use the term "dopesheet" and the "animation transistion crossfade" since timeline is something else entirely (and doesn't work on avatars) if people try to search for it. :) Also worth mentioning that write defaults was left on here.

[@mcwifithethrd2714]

Can you simplify Im confused is it for each animation in the clap layer and if so do you turn on motion time on both and which parameter do I use

[@swifter46ter]

Oh my god I have got to do that pip-boy now. I love fallout!

[@Cazra-VaporwaveWitch]

I didn't know about this colliders system before seeing this video. I'll need to try playing around with this later! :D (It's too bad Quest avatars are automatically marked as "poor" if they have any kind of particle system though, so I'll need to come up with some kind of creative blendshape animation for high-fives)

[@Dante02d12]

So how many people used this tutorial to make the "pull my finger" joke? No one? Oh bummer :(. Great tutorial! You're by far the best to follow for anyone wanting to dive into Custom Avatar making. Have you considered making tutorials for specific but advanced examples? For example, in the Avatar Dynamics official trailer, they showed a magician changing her outfit with the tip of her wand. It also doesn't just switch between them, there's a cool animation during the change.

[@MetaPlay23]

Perfect tutorial as usual! Now I need to figure out how to do all of that with a gun and constraints oof

[@War_Beetle]

I love u so much, thx for this video

[@deprecatedaccount8027]

Thanks for uploading this - I've been trying to do something similar to this, except instead of it being a high-five I plan to have a giant BONK sound or something play whernever I slam a Splatoon roller against someone's head or body. x3

[@fufu2316]

I love your tutorial style its not only detailed but also very easy to understand too. And how do i make it toggle with contact? Trying to make a prop that my avatar can grab

[@nitorik1578]

Hello Sippbox, just wanted to say you're the best of the best, thanks to you i've been able to learn a lot in unity and has made my experience way better, your videos are so helpful and the music you choose is also the best, just finished trying out the clap tutorial and it works amazing in my new avatar. just one question tho do i have to delete the duplicate of my avatar after i'm done with recording the animations?

[@SippsAvatarBox]

You don't have to keep it, the duplicate is only for recording animations on. Alternatively, you can enter play mode and animate directly on the base instead of making a duplicate, then exiting play mode when you're done animating. I explain the duplicate method in my videos cause i find it easier for beginners to understand.

[@redinkdemon]

ths was helpful

[@carloguerrero6583]

Appreciated ^_^

[@seven2z964]

is there any way for me to make actual toggles with these (pressing a button and having it act like an actual button that stays down then when pressed again comes back up?)

[@mistiee-9946]

im eager for this. I am too lazy to find a way to make it quest compatible but one day... one day.

[@planetpaddys]

will you do a tut on how you did the "grabbing crowbar" with the reciever/senders?

[@fallouthunter026]

can you do a guide on how to make particle effects or particle effects that are triggered from gestures when holding something like a weapon?

[@rainhightz]

Hey great tutorial your video's have helped me out alot in avatar creation , however i have one question about this one is there anyway to make it so when you press the contact after moving your Collider away the animation or toggle stays on until you put your hand back in the contact and move it away? , so like an actual button you press it once it stays on until pressed again

[@HikikomoriDev]

Yay it's Karin!

[@coffeebeenzz]

For anybody having issues with the capsule not giving you a height setting, this is a bug. Go to the settings of your inspector tab and turn on debug mode to have it appear.

[@acyiz]

nice i used this to make a axe that spews blood

[@Airbomb]

Heya, I used this tutorial to make a Half Life crowbar that makes the "Clang" noise whenever it hits an avatar, however I want it to be able to overlap itself, so I can hit it as fast as I want without having the sound cut off whenever I stop, and I can't quite figure out how to do that.

[@aamuchii]

I've seen some avatars where on contact like touching a prop on their side it switches to the hand holding it. It would be awesome if you could do a tutorial on that!

could you ever so possible do a tutorial on avatar world object? like when you do a toggle on an avatar a world object spawns.

[@Flur-E_Fury]

so idk if you have ever encountered one of the musketeer safe house avatars but they have it to where you could pull the night vision goggles down and up. i was wanting to know how to do this because i am making an avatar with nvgs on it.

[@VrmastermindOffical]

could you possibly show how to make something like this but where the contact of a person stepping on the ground activates a audio sound or an animation cause I have no idea on how to do that.

[@antoniocruz-xd4us]

Could you make a tutorial on proximity switches I've been trying so hard to make one but keep failing

[@thelivingcat0210]

Is there a way to get it to detect literally anything when it is touched? I have an idea for an avatar where he produces so much heat that steam/smoke will emit from the point of contact when ever he touches something

[@planetpaddys]

is their a way to toggle the slap on or off as in when toggled off, when you hist someone head it doesnt do the efcct, and while toggled on it does ???

[@infernothegreat1041]

[@thelazymelon9783]

Can we do toggle button by using contact?

[@ZorgyBabyVR]

I always love your tutorials! I have a questions this time. What is the benefit of duplicating your avatar to make the animation? I haven't been doing that, but it doesn't seem to have created any problems for me.

[@SippsAvatarBox]

It's to prevent your avatar from getting stuck in the "Bicycle Pose" that happens when recording animations. Alternatively, you can enter play mode and animate directly on the base instead of making a duplicate, then exiting play mode when you're done animating. I explain the duplicate method in my videos cause i find it easier for beginners to understand.

[@ZorgyBabyVR]

​@@SippsAvatarBox Great thanks! My avatar has an "Idle" animation so I use that to switch back to the typical relaxed T-pose. Just playing around with it now, my avatar would automatically go back to the relaxed T-pose after turning on and off play mode. Thanks again for the great videos!

[@hugetoystorynerd]

hey sip, is it possible to make an actual button with contacts? like have a button push in when touched and then have the button go to the default state when not being touched? like how buttons work on a buzz lightyear toy?

what if you dont have vrc contact sender or reciever as a thing, how would you make a contact, because mine apparently doesnt have those scripts

so ive followed this tutorial perfect what i am trying to do is, ive got an arcade machine on my back and ive added contacts to each button and when they come in contact with senders they do not work ive added everything. btw can you update your discord link

[@redmaster12251]

I know I'm a little late to the party but is there a quick way to make this work for both hands? I tried to mirror what you did for the right hand, but the left hand doesn't want to react for some reason....

[@MrTooncat]

Is it possible to put the VRC Contact Receiver component on an game object in a world so that when anyone's avatar touches it the object would play a sound or animation? Or does this only work for avatar to avatar collisions?

[@shantabrown9465]

soo when it came to doing a boop for a contact receiver it works in unity when I test it but don't work in VRC its set up but just saying naah XD is it just a avatar thing or something else

[@GreenSoup2HoT]

how do you make it so Both hands can clap? i tried duplicating the contact to the other hand and it doesnt work.

[@ObsequiousV4]

I have a question regarding a particular scenario: If I want to turn off the mesh of a large hat on my head for anyone who happens to clip into it with their face, I think I can do it with contact receivers. The caveat here is everyone will see it, right? I would like it to be local to only the person triggering it. Otherwise the hat will turn off and on at random as people bump into me which I would rather not happen. I would like to avoid poking people with it since it's a bit large. My solution up until now has been making myself small enough not to be in the way. Is it possible through contact receivers to do this, and if not is there another way?

[@Star-gg6ur]

You dont need to make a secondary avatar anymore?

[@Doc_2BDamned]

I can't seem to figure out how to make it so when someone presses the contact receivers the change is permanent and doesn't go away when me or someone pulls their finger away, can anyone help me out? It uses and avatars blendshapes btw

[@OrganicKourts999]

I need a pip oh I. Vrchat exactly like that.

[@Qushey]

can this be test first in unity before upload?

[@MisterDonut420]

I have an issue with the On Enter receiver type. It doesn't set the parameter to 1 when the contact receiver is activated. Any suggestions?

[@ImSemmi2711]

My contact receiver won’t turn on, I have the filtering allow others turned on but it won’t activate when someone touches it. What do I do?

[@KaimaiTinsnake]

I have a problem with testing my contacts in Unity and nothing on google apparently has information on this issue so I've come back here to ask; My receivers and animations work fine ingame, but on Unity's side when testing with a Sphere that has a Sender with the proper values (finger, hand, etc) in it, it simply does not trigger the animation to play that's supposed to, even if the parameter itself changes from 0 to 1 in the inspector of the receiver object. I've tried with blank animator controller and also using the FX animator in the controller field, neither works. This makes testing receivers extremely hard since every time I make a slight change or something doesn't seem to work I have to tweak it, build the whole avatar, go ingame and try to find someone to press my buttons just to try them out. Obviously entering the game in desktop mode while working with unity, so I have no hands with which to try it. I've had this issue ever since the avatar dynamics update, could never get the sender test sphere to work in my avatar project. Does anyone have any way to fix this or any insights on what might cause this? If you need additional information I'll gladly provide it. Unity version 2019.4.31f1 with SDK ver 3.2.1.

[@eatitboiiissss8344]

will it work for quest

[@kl9043]

1) so does this mean if I set the parameter as something generic sounding like "weapon", ANYONE elses avatar with the same naming scheme for theirs will interact with it? if this is the case it would be really cool if there was like a collaborative database for parameter names so people can make sure theyre setting things up to work with the most avatars possible (or even use it for help avoiding accidental interactions). 2) random optimization question: "is animated" on physbones is supposed to be reserved for objects that are animated since it uses more processing power to constantly update. thing is, you can actually animate "is animated" to on or off in animations themselves. would it technically be more optimized to never use "is animated" at all and instead just set it to animate to active during the animations themselves?

[@SippsAvatarBox]

1. If you set one of the *tags* on your contact receiver as something like "Weapon" for example, anyone with a contact sender on their avatar with the tag "Weapon", will be able to have it interact with your Contact Receiver. So let's say I have a sword on my avatar with a contact sender on it with the tag "Sword", and on your avatar you have a shield with a contact receiver also with the tag "Sword", which when interacted with plays a sound effect. If I hit your shield with my sword, it will play the sound effect. 2. I don't believe using the Is Animated checkbox in animations is supported behavior, so I wouldn't reccommend using it that way.

[@undermoons7799]

If I were to want the expression in my avatar to change when clapping/headpat, what should i do?

[@SippsAvatarBox]

if you want to add a facial expression to the clap thing, just add the blendshapes into the clap animation. If you want to make a headpat contact, put a contact receiver on the head with the Hand tag, set it to constant, set a parameter name. Then in your animator set up a facial expression toggle like you normally would, but use the parameter you set in the contact.
