THANK YOU. I'm doing my masters thesis on Project Management in a virtual space using only hand tracking, and I needed to be able to write on sticky notes in VR, and was freaking out that I wouldn't be able to do it before testing. This tutorial literally saves my paper. So again, thanks from the bottom of my heart.
Not sure why I don't have Enumerable as an option. At 11:30 in video. Using Hurricane VR. Only have IEnumerable as an option with no .Repeat. Solved from discord member. Add "using System.Linq;" to start of script
100% true. But I like having answer on youtube also. Because much easier for me to find again if I have the same problem in the future. Thanks for all your work.
Your tutorials are SO good! I can't believe you don't have tons more subs. You've inspired me to get back into VR programming after a few years break! Thank you!
For everyone that's having the jittery marker issue, first check and make sure that the handle and marker tip transforms are reset to zero so they are in the same position as the marker object ( with the exception of the tip which has to be moved along the y axis to be at the end of the handle). Another thing, is if you have a character controller on your player, that will cause the marker to jitter when it hits the capsule collider. I know adding one wasn't in the vid, but I wanted to interact with objects so I added one myself, and it caused problems so it's worth mentioning.
Any idea how to make the whiteboard grabbable so it can be moved around? I tried adding a XR grab interactable component and rigidbody, but for some reason the markers then don't write on the whiteboard.
@JustinPBarnett I followed the instruction in this video and it worked perfectly fine. However, When I add a material with a texture like the outline of a picture to the canvas and I enter playmode, the canvas automatically turns back to being blank. Any ideas on how I can make this work?
Thanks Justin, you are always my teacher! I tried your code, but I find that the plan of "setPixels() + Apply()" are too slow especially when I use a big texture size.And it get worst when I made a blackboard eraser in this way-- I have to use many small square to approximate the shape of blackboard eraser Now I find a way to improve it that we can send an extra "trial texture" to a shaderGraph, then mix it with original texture, and the way to draw the trial texture is using the `rendertexture` and `Graphics.DrawTexture`. After that, almost all the calculation happened in GPU, I finally get a fps improvement for nearly 300%!
@@emirhanyilmaz9695 firstly you can see this video: th-cam.com/video/ftCyZ7F5q9E/w-d-xo.html this video is about a "snow trail”effect，it create the "trial texture" using VFX system, but it still not fast enough. I change the method in this video on how to create the "trial texture" by create a `RenderTexture` and call the `Graphics.DrawTexture()` to draw a small pen texture(a sample penSize*penSize texture created in runtime) on the `RenderTexture` when the pen hit the board----instead of setPixels() and Apply()
Another thing you could do is calculate the distance between last pos and current pos, and scale the number of interpolations with this value. Otherwise, you're doing 100 steps regardless of the distance between frames.
Subscribed simply because you are a fellow Rider user :D Great tutorial by the way - it has helped me understand the logic behind realtime painting for my own project. Thank you :)
great video. suppose I have a multiple amount of whiteboards in the world would I have to attach this script to every single whiteboard in order for the marker to draw on them? What would be the easiest way to do this?
@@fernandocgi3874 Hi! How did you do this? When i tried to make an eraser (basically by making a marker with a color set to the color of the board) it didn't come out right. Even if both materials were the exact same (ex. pure white), the eraser always acts like a highlighter, showing up brighter than the board (maybe because it doesn't obey shadows? Unsure.
Hi my marker is all jittery when I pick it up and it still shakes when I try to draw on the whiteboard with it. I have the lines of code for freeze rotation in place, what else could possibly be the issue?
@@JustinPBarnett thanks I’ll try that. I ended up just ditching the marker all together and made it so that it drew when your hand raycast hit the whiteboard and you were holding the trigger, made things a lot easier
Hey man, thanks a lot for this! Could you possibly give me a quick idea on how to make the drawing only apply to the surface in front, and not to both sides of the object? (I wanted to be able to paint a 3d object, like a vase)
very informative tutorial, can anybody give me a direction as to where I should look or how to go on about making a circle instead of 5x5 squares from marker
did you get it?I still need help because i figured out how to do the circle but i'm having problem with setting the background color for the corners of che square that wraps the Circle
Whenever the marker touches the board, it bounces around like crazy(it also jitters a little when I grab it), so I cannot draw it properly, any suggestion for solving the problem? Thanks.
@@JustinPBarnett Hi everyone that's don't really solve the problem.. Have you got any other idea? is there something to do about the physic of the pen?
Another great tutorial. I was wondering how to get rid of those red pointers linked to hands and swap hands with some nice prefabs. Would it be simply add hands as prefabs to left and hands controllers ,or is it something more tricky to set up. Thanks
Nope that's the easy way to do it! You can even set up a trigger to close/open the hands there too! To prevent the pointers from showing, just change the valid/invalid colors to transparent in the XR Line Visual
Sorry, I got one trouble when I type the code which that I cannot find "Enumerable.Repeat". As when I put the cs folder into unity, it shown error. Can I get any help here? Thanks
Thanks Justin! Just wondering if you would make a quick video just explaining how to setup Hurricane VR and Hexabody VR? I bought both and got disappointed when I realized that it wasn't so simple as clicking a button to setup😂
Do you want to set Hurricane VR up for this or just in general? For this it seems to work. Using Hurricane VR and Final IK integrated. If having a problem setting up Hurricane VR the discord for it is great. Lots of help there and a few videos.

Hey man, not sure if you read these but worth a shot. Currently trying to navigate the new XR Input system and I gotta say. It is fucking me up. It seems pretty simple to set up normal functions that are included. But trying to create unique functions seems so difficult. I am curently just trying to transfer some old code I had from a SteamVR game that used GetStateDown and GetStateUp and I have no clue how to just check for trigger pressed and trigger released on this XR input system. It is really frustrating the hell out of me.
Hi! thank you for your great tutorial. But, unfortunately, I can only draw a diagonal, straight line with the marker. Does anyone have a same problem like me? I follow the exact same script what Justin wrote, but can't draw it properly.
I had that same problem...it was because I had different capitalization on the name of the WhiteBoard.cs .... and followed Justin's code with the 'B' in Whiteboard being lower case.
Hey Justin, this is working great for me, thanks a lot! I still have a weird issue though, maybe it's a quick fix: On my Markers Tip, when I try to draw something on the whiteboard, only one edge of the tip can actually draw, the others won't do anything. Kinda hard to explain, it's like it can only draw with the bottom side of the tip. The one edge on the tip, that is working also slightly clips into the whiteboard - the other edges don't do that. I did try to adjust the colliders on the tip, but it didn't help. ^^
On the line 'if (Physics.Raycast(_tip.transform.position, transform.up, out _touch, _tipHeight))', try change the 'transform.up' to 'transform.forward' or 'transform.right' (or rotate the tip)
@@sneakyfox03 It took me a while but I finally implemented your fix and yeah you're right. The problem was that my marker was rotated and that lead to problems with the actual drawing so I could fix it by just rotating the marker! :D Thank you :)
@@sneakyfox03 Just wanted to say thanks. This helped resolve my issue with the marker not drawing except when a specific corner was touching the whiteboard too!
I ran into this issue too. In my case, it was because I was using my own marker model which threw things off. The pen drawing before touching the whiteboard was due to the ray cast being longer than the model's tip height. The length of the ray cast is set by the length of the tip in this line: _tipHeight = _tip.localScale.y; This works in the tutorial because Justin created the maker tip from a 1x1x1 cube and then scaled it down to 0.05. So when the script is grabbing the local scale, it creates a ray cast that's only 0.05 meters/units long. I modeled my own marker and then froze all the transforms, so my local scale was 1. This meant that the ray cast was being thrown a full meter in front of the marker. Oops. To fix this, the _tipHeight needs to equal the actual size of the tip. Which you can do by either hard coding in the length of the tip, if you know it (or stumble on it by trial and error). In my case, that would have been: _tipHeight = 0.012f; Or better yet, use the mesh collider on the tip to get the length: _tipHeight = _tip.GetComponent().bounds.size.y; Since my pivot was in the center rather than the bottom of the tip, this still cast a little too far in front. To compensate, divide by 2 to get the distance from the center to front edge of the tip: _tipHeight = _tip.GetComponent().bounds.size.y / 2; That did it for me. Don't know how much help it is to you 9 months later, but there it is. And thank you Justin for this and all of your other great tutorial! Much appreciated!

Great tut! I changed the raycast a bit to allow the full height of the tip to be used to draw, otherwise inserting the tip past the midpoint would not result in a raycast hit: Physics.Raycast(_tip.position - transform.up * _tipHeight, transform.up, out _touch, _tipHeight * 2);
the marker script has some incompatible code if written in visual studio. I am unable to do Enumerable.repeat, so i tried IEnumerable.repeat, but repeat won't work because there is no contained definition for repeat, apparently.
Using ( _whiteboard.texture.Apply(); ) is very expensive and causes my 200FPS scene to drop down to 28FPS. Really bad for VR! Are there better methods to get the same result?

The one edge on the tip, that is working also slightly clips into the whiteboard - the other edges don't do that.
I did try to adjust the colliders on the tip, but it didn't help. ^^

On the line 'if (Physics.Raycast(_tip.transform.position, transform.up, out _touch, _tipHeight))', try change the 'transform.up' to 'transform.forward' or 'transform.right' (or rotate the tip)
@@sneakyfox03 I will try it, thank you :)
@@sneakyfox03 It took me a while but I finally implemented your fix and yeah you're right. The problem was that my marker was rotated and that lead to problems with the actual drawing so I could fix it by just rotating the marker! :D
Thank you :)
@@sneakyfox03 Just wanted to say thanks. This helped resolve my issue with the marker not drawing except when a specific corner was touching the whiteboard too!
the rotation lock doesnt seem to work. any idea why ?

Bro! Did you made the script for the eraser? It would be super healpfull for my vr project! So i would really aprecciate a tutorial c: ,Thanks!
u got the script brother ?
Anybody else has the problem that this just works in the Unity Editor Play mode, but when you build the project the marker just doesnt work?
Yea I've heard that mentioned a few times now... join the discord if you can't figure it out and we can help you troubleshoot
yes i am
did you solve it
My pen is detecting the wall too soon, and draw before i even touch the whiteboard, and yes I checked the colliders... any help???
I ran into this issue too. In my case, it was because I was using my own marker model which threw things off.
The pen drawing before touching the whiteboard was due to the ray cast being longer than the model's tip height.
The length of the ray cast is set by the length of the tip in this line:
_tipHeight = _tip.localScale.y;
This works in the tutorial because Justin created the maker tip from a 1x1x1 cube and then scaled it down to 0.05. So when the script is grabbing the local scale, it creates a ray cast that's only 0.05 meters/units long.
I modeled my own marker and then froze all the transforms, so my local scale was 1. This meant that the ray cast was being thrown a full meter in front of the marker. Oops.
To fix this, the _tipHeight needs to equal the actual size of the tip.
Which you can do by either hard coding in the length of the tip, if you know it (or stumble on it by trial and error). In my case, that would have been:
_tipHeight = 0.012f;
Or better yet, use the mesh collider on the tip to get the length:
_tipHeight = _tip.GetComponent().bounds.size.y;
Since my pivot was in the center rather than the bottom of the tip, this still cast a little too far in front. To compensate, divide by 2 to get the distance from the center to front edge of the tip:
_tipHeight = _tip.GetComponent().bounds.size.y / 2;
That did it for me. Don't know how much help it is to you 9 months later, but there it is.
And thank you Justin for this and all of your other great tutorial! Much appreciated!
I aint reading allat but thanks
Can You make how To Make a gun which shoots?
Yea that's in the pipeline!
Oh ok
Where that
How can I use it in a multiplayer game?
All you really need to do is sync the markers. Then the whiteboard texture should update locally based on marker position no matter who's writing.
Could you put the code on your patreon
It's there! Here's the link if you need it: www.patreon.com/justinpbarnett

Same here! Anyone? Thanks
you should addd code in description as well its a good practice
The code is available!
@@JustinPBarnett sorry i didn't find it where is can you send me link
@@JustinPBarnett Ever since Half Life: Alyx, I KNOW you've imagined playing around with a whiteboard in your games. Well today is the day! In this tutorial I'll show you how to set up whiteboards and markers using Unity VR. (This will work for any Unity VR framework too!)

Enumerable isnt working in the code
Just add "using System.Linq;" to the top of the script :D
👆
I am from Vr super jam. I created veat sager
👋
Great tut! I changed the raycast a bit to allow the full height of the tip to be used to draw, otherwise inserting the tip past the midpoint would not result in a raycast hit: Physics.Raycast(_tip.position - transform.up * _tipHeight, transform.up, out _touch, _tipHeight * 2);
Hey what do you do when it says "Enumerable" doesn't exist
using System.Linq
Is there a way to pre-draw something on the whiteboard that appears every time you load the game?
the marker script has some incompatible code if written in visual studio. I am unable to do Enumerable.repeat, so i tried IEnumerable.repeat, but repeat won't work because there is no contained definition for repeat, apparently.
Huh, that's a C# thing not a visual studio thing so it should work regardless of editor
@@JustinPBarnett I found the answer on your Discord server. Thanks for the great tutorials.
@@kelleyintegritysafetysolut484 awesome!
@@JustinPBarnett I'll be supporting you over on your Patreon within the next few days. Thanks a million.
"using System.Linq"
Using ( _whiteboard.texture.Apply(); ) is very expensive and causes my 200FPS scene to drop down to 28FPS. Really bad for VR! Are there better methods to get the same result?
I'm having the same issue right now. Have you found a solution or alternative methods yet?
