HI there,

I have World Space UI that is a child of a phone that I can pickup with my Vive controllers. When I am moving around the phone the UI of the phone screen lags behind the phone. I know this can be solved by just building the game and running it from an exe, but I want this to work in the editor as well. Any suggestions?

Thanks,

Dan

Hi,
I just found a bug that causes this Graphics.PresentAndSync. It really causes a huge performance drop.
I hope someone from Unity will help us.
IMPORTANT: This bug is obvious in Galaxy Tabs. In two of them that I used was a nightmare (FPS drop from 60 to 30)

I have attached a small video here for all to see the problem.

The animation is done by MapController script in the update function under Key Down 'J'

This is driving me up the <bleeping> wall.

I have a terrain. I have a canvas set to world space so that I can use UI elements on top of the terrain.

When I click somewhere on the terrain a UI Canvas button pops up. I am using the mouse's world location and converting it to the canvas location for the button. I use anchoredPosition for setting its location.

The first time I click the mouse button everything works perfectly. The UI button's anchoredPosition is changed to where I want...

Hello All,

I try to instanciate a GameObject ( I mean a gameobject with a transform position, there is no canvas on it) => it's a dice Prefab for example

And I do have in my project a Canvas (screen- space overlay) with a Panel => deviceContainer

Si I do not have issue to instanciate dices from the prefab :

diceClone = Instantiate(dice, new Vector3(x, y, 0), Quaternion.identity);

But how I can be sure that my diceClone will be randomly inside the panel DeviceContainer (even if I...

Hi all!

I'm working on a game that uses Unity's (2017.1) multi display feature. While testing it out in the editor (macOS Sierra 10.12.3) I noticed very strange behavior, and I'm reaching to you guys to see if we can determine it to be a bug so that I can report it.

1.- Create a new Button in your scene (will autogenerate a basic UI setup with a canvas)

2.- Have more than one GameView tabs open in the editor.

3.- Click play.

4.- UI input (both mouse and keyboard) will completely cease...

I'm using an out of the box UI button and all I changed was the "Highlighted Color". When I run the game, the button highlights correctly with mouse over and reverts to normal when mouse leaves but when I click on the button, the highlight color stays on even when the mouse leaves the button area. I have to click "somewhere outside the button area" to get the highlight removed. Is this intentional? Anyone else have this problem?

I don't know if i'm at the right place, but here's what i'm trying to achieve :

I have an image, which is just a plain menu background. I want this image to fill the whole screen, but keep it's aspect ratio.
I don't mind if the image is truncated in one of the axis. that's actually what I want it to do.

Problem is, I have no idea how to achieve this with the new UI.

Here's my actual set-up :

- Canvas -
set to Screen Space - Overlay (With pixel perfect enabled)

- Image -
Anchors set to...

I have an app (iOS, Android) to which I'd like to add networked text chat. Since our audience is sensitive, and we don't want to introduce profanity filtering etc, and since most of our audience seems to write all of our Google Play reviews pretty much entirely in emoji (yeah, seriously...) we'd like to offer emoji-only voice chat.

Is it possible to display a textinput field that only accepts and displays emoji characters?

Hey guys,

I have a list setup as follows:

ScrollRect / Mask
--Content Size Fitter / Vertical Layout Group
----LayoutElement 1
...
----LayoutElement N

Now, I want to be able to drag one item and pull it up or downwards in order to change its position in the list.
I don't know how to do this. I tried a lot of things, but It would be great if someone could point me to the right direction. I googled a lot, nobody seems to have this desire?

I'm updating the position of a panel via script. If I set the panel to active then set the position at the same time this happens.




Here the rec transform is in the correct position (the white square outline) but the image on the panel is in the old position (black square).

If it is already active and I set the position then everything updates correctly.

How can I get the image to update when setting the position?

Hey,

I'm working with the hololens and it is very sensitive to performance.

Is there anywhere I can read on best practices with TMP in regards to performance?

Anything I definitely shouldn't do? like with ugui best fit option

My first toe dip into performance has shown there are different prices for TextAlignmentOptions.

For a year or two now, there's been a bug where UI that uses layouts or anchors in a scene causes it to constantly overwrite the position and size values in the scene whenever entering or exiting playmode or opening or closing the scene. It makes source control super annoying since the scene files are constantly being edited and changed even though there are no actual changes. Is there any way to stop it from doing this? I haven't narrowed down exactly which components cause it, but I'm...

Hello all,

Please excuse my question, but I am a beginner with unity 3D and I need your help.
At run-time, I want to put some text on 3D object.
I find this old post
http://blog.almostlogical.com/2010/...time-in-unity3d-without-using-render-texture/
but I think that textMesh is probably the best solution.
Do you have a snippet or a short example ?
Thanks a lot
