Casters’ gargantuan mischievous misadventures in the virtual world

[scenic shoal]

I successfully translated this Unity tutorial to Godot, used some tricks and got a working Physics XR rig wihout any tools of the XR toolkit !

[solemn herald]

I'm really looking forward to your tutorial or more info on this stuff! I'm wanting to do something using a VR physical body in my game as well.

[scenic shoal]

So what i have to do,

• Add direct movement
• Fix grabbing rotation
• Force grab ?
• Fun stuff lol
• Tutorial + Devlog
• Back to work(Tools,Ragdoll,Map) 🤠

I got exams tomorrow and Tuesday so this will take time

[solemn herald]

On the direct movement I've noticed that having some ramp up/acceleration is good for reducing motion sickness.

I've been trying to make walk in place/jog in place locomotion but it's pretty complicated. Malcom Nixon created one that's halfway there using arm swings for the GodotXR toolkit but I'd really like it to be based on head movement like what Nimsony figured out in Unity. Sadly there's no tutorials on how to do it so I'll just have to figure it out on my own. When I do I'll share it with the community.

What i did so far

Its not perfect, its Godot

[solemn herald]

That's really cool great work

[scenic shoal]

So what i did so far

Adjust body,make it match body and scale
Make hands match controllers
Make body move according to actions ig
Grabbing
Interaction with rigid
Fix grabbing offset
Fix grabbing rotation
Force grab ?
Add direct movement
Fun stuff
Tutorial + Devlog
Future(Tools,Ragdoll,Map) 🤠

[sand cliff]

stupid question but how do you attach grabbed objects? I'm working on my own hands/interaction system and so far all i can manage to do is make the hands(rigidbody) follow the controller(apply_force/apply_torque)

[scenic shoal]

I use pinjoint, the regular one not the jolt one, but there is an issue with that and im fixing it

[scenic shoal]

Ill see

I have literally the exam to get middle school diploma tomorrow and im working on vr physics interaction in Godot 😭(Tears of laughter)

[scenic shoal]

Main issue, probably wont be fixed, hands can’t follow at high velocity but ill try to like adjust the force according to the velocity

[solemn herald]

Please study for now! This stuff will still be here when you get back. Good luck on your exam!

[scenic shoal]

Thanks !

[scenic shoal]

Imagine if someones sneak to my computer and takes everything 👀

[scenic shoal]

I will try using joints instead of velocity tomorrow, may fix many things for later

[scenic shoal]

Exams are over, i will start working on it right now

[scenic shoal]

Bad idea, hands won’t be affected by objects weight

[solemn herald]

I think to fix this you need to do something where the pose/position of the joints is where the limb is trying to head towards. I believe bone works did something like that but actually using forces that get applied to each limb. I think a sort of active ragdoll approach is what it should use rather than just applying velocity but I'd have to see what you were doing code wise to know for sure.

Here's some stuff that might be helpful

[scenic shoal]

Ill read that later but thanks

[scenic shoal]

Yes thats the arms, didn’t add arms for now but ill try to do the nimso studio thing

The second video tho is very helpful ill try it thanks @solemn herald

[solemn herald]

Sadly he doesn't explain how the arms work with code there and how he says it's not IK but I think he uses IK to direct where the joints should move using forces.

[scenic shoal]

@solemn herald Have you ever tried that active ragdoll technique for vr in godot ?

[split lake]

actualy i did in godot 3.5 we tested this with the active ragdoll addon, since it was pretty cumbersome to create we actualy abandoned the idea or well sybiote left, so i wasnt rly into gettin this done alone but yes it is doable and verry much possible

this 2 are from the old dojo days^^

[split lake]

but in a nutshell as long as you have physical collision on your hands, you can manipulate an active ragdoll

[scenic shoal]

Yup

But my physics rig is more than that

Its like everything is interactible

[split lake]

thats good so that means that in reverse one could code to grab the player and hold its wrist for example by using the active ragdoll with ik

[scenic shoal]

Wdym ?

[split lake]

what i mean is just an example what could be done with ur rig and active ragdolls, anyways

[solemn herald]

I haven't tried active ragdoll in VR but I've been planning to.

[scenic shoal]

My rig does more than just interaction with rigid bodies

[solemn herald]

He was saying that in theory something in the game could grab onto a part of your player skeleton and prevent you from moving around very much.

[split lake]

right as mittens said, anyways it is to be seen what your rig can do or not and that is ok, take your time... the game jam might be a good oppertunity to test it in action and expand it

am probably not gonna join the jam but i do have a suggestion to make regarding it, take the ppl in this thread and ask em if they wann join the jam with u as a team, this way you could get some help testing things and maybe even get things done for the rig

[solemn herald]

If you'd like to collaborate for the jam I'm working on a walk in place/jog in place locomotion system but I'd also like to help make the rig better or help make it into an actual game.

[split lake]

theme is to be announced but since your talkign place/jog in place... a horror type a la slenderman would make pretty much sense

[solemn herald]

Yeah I was actually starting work on a horror VR game but I hadn't gotten too far. We'll just have to see what the theme is I guess.

[scenic shoal]

Collaboration with me ?

Ill prefer do it alone this time to like see what can i do alone

[scenic shoal]

So the idea is to like connect a skeleton to the player and make an active ragdoll that targets the skeleton

🤔

[solemn herald]

Yeah I that's pretty much what I was thinking too

[scenic shoal]

Mittens this is genius !

Casters’ gargantuan mischievous misadventures in the virtual world

[solemn herald]

It's not completely my idea I've just been researching solutions for a while lol

[solemn herald]

I was wondering if you've made any more progress on this project? @scenic shoal

[scenic shoal]

Its open source on github do whatever you want with it, for now i am working on multiplayer with godotsteam and i also started music producing

[solemn herald]

That's awesome, thanks for sharing the project.

I hope your future projects go well. I've always liked the music production side of development as well.

[scenic shoal]

Also working on something bigger than ever

[solemn herald]

Sometimes when I'm tackling a large project I like to break it up into smaller projects that build on top of each other so I feel accomplished with each step rather than looking at the mountain still left to work on.

[scenic shoal]

https://github.com/Godot-Dojo/Godot-VR-PI

[solemn herald]

Like I want to make a large multiplayer rogue like so I'm first building a dungeon generator then working on combat and movement then finally working on NPCs and itemization.

Then after I've learned lessons from those projects I'll combine them into something good enough to sell.
