New Device Simulator (preview)

Very nice. Congrats.

 

Very important feature, this is going to save lots of time and help avoid surprises!

What about DPI simulation, does this package support it?

 

+1

 

Looks like a great feature! We are restricted to LTS releases though, so can this be back-ported to 2018.4 LTS please? It would save a huge amount of time for us!

 

Hello @JC-Cimetiere this looks like a really cool feature. I installed 2019.3 and can't find it in the package manager.
Also the link to the documentation has been removed.

Is this package really available today ?

 

Unfortunately we cannot in this case. To build this feature we had to make some changes to some core Editor code which allows us to inject a mocking layer. This is then used by the Device Simulator package. To ensure we maintain the stability of LTS builds we do not backport changes of this scale. On the plus side 2019.4 will be here before you know it

 

Make sure you have turned on 'Preview Packages' by pressing the Advanced menu button, see screenshot below:

 

Pretty cool feature @ScottF , thanks!

One thing though, the link to the package in the blog post is dead.

The simulator will accurately report the screen DPI so for example things like Unity Canvas Scalar will properly reflect the DPI and any user gamecode should also properly be reflected.

Seems to be working now, at least it resolved for me to: https://docs.unity3d.com/Packages/com.unity.device-simulator@1.0/manual/index.html

 

Hi,
Does Device Simulator supports Linear workflow? Right now it seems it doesn't apply the gamma to the output we seen in the simulator.

Cheers,
Daniel

 

Looks great! It'd be nice to have some preset scaling options similar to Xcode's simulator (pixel-accurate, point-accurate, physical size). I know physical size can be tricky on some platforms where the editor DPI isn't known/accurate, but a manual override for that value would be fine.

 

@ScottF I still get a 404 error. I tried in private browsing, same thing.
Not a big deal, since the package is available through the editor manager.

 

This looks great.

For those who are working on a version lower than 2019.3, or people who want a larger quantity of devices with their picutres, we made a similar asset for previewing phones and tablets, that works for all Unity version from 5.0 to 2019.2.

It is called “Multi Device Preview & Gallery”.

You can preview more than 200 device presets and more than 50 full phone and tablet preview, including phones with notches. It also include popularity presets to target the popular phones of your target platforms. You can preview multiple devices at once in the gallery.

You can find the list of more 200 phone and tablet presets in the asset store page: https://assetstore.unity.com/packages/tools/utilities/multi-device-preview-gallery-82015

 

How about simulating a specific device’s DPI?

 

it would be great to be able to simulator multiple screens (multiple camera views) easily

 

Awesome package, will it also be possible to take screenshots?
Will it eventually also be able to simulate Google VR overlay?

Would be nice to have an in editor way of making screenshots Automated so that if for instance you have a template app you can create screenshots for all resolutions required by Apple without having the device in-house.

It would also make it possible to do runtime testing then by generating screenshots of an automated process and compare them to check for differences. So that when you do an update for UI code or UI package or Unity Engine update that you can easily check if all is still working as expected or that it requires a fix in code.

 

You can do that with both my assets, Ultimate Screenshot Creator or Multi Device Preview

 

Yes I've seen your self advertising post. But I'm not looking forward to purchase and use more packages from the asset store. No offence. I just have multiple terrible experiences with the Unity Asset Store, that I want to refrain as much as possible from purchasing and using them.

Hence I ask if there is going to be functionality from Unity's own device simulation package for this. Like is the Device Simulator compatible with

ScreenCapture.CaptureScreenshot

. If it is then possible to overlay it with a Google VR overlay then it would be perfect.

 

Mouse input on the device simulator is not working with the new input system

 

Thanks !!! This is a first step to improve our mobile projects.

 

I understand your desire to focus on Unity included features instead of purchasing assets.
Note however that not all publishers are terrible, most of us try to provide good assets with an efficient customer support.

 

This is on the roadmap, including ability to simulate newer use cases like fold/unfold on those newer foldable displays. This is not our highest priority (we want to build out database of more prevalent devices first) but is coming!

Heard this request a few times at Unite. Will discuss internally the best way to do this. For example we could make a button & API thats specific to simulator or perhaps as you mentioned it working directly with the existing CaptureScreenshot API might be best. I didn't test it yet but *fairly* certain if you call that API in simulator today you would get the entire editor window.. Thanks for the feedback!

 

Thanks

 

How do we create a new device definition? It doesn't seem like you can just copy/paste a new JSON file in the DeviceDefinitions folder...

 

Quick feedback after using the feature today -

We develop for portrait mode, when developing in "game" mode and switching to "Simulator" mode the game view is super tiny because of the Specs tab
It would be great if I could hide the tab, that way wouldn't need to enlarge the Simulator view every time I need to change to simulator mode

Also the colors are different in the Simulator view, is that intended?

 

Hi.
Is it possible to use ARFoundation capabilities in the Device Simulator?

 

I just tried out preview 1.1 on OSX, Unity 2019.3.0b5, and the simulator view was inverted, it looked like it was scaled (-x, -y)

 

Whats wrong? I just want previews to be the same.

 

Why I don't have it device simulator? I turn on preview package but nothing appear

 

I understood, my unity version it is old for this package

 

Device Request: Nintendo Switch

 

Hi.
Thank you for the awesome tool.

It would be great if you could minimize the window in such a way that only a device would be visible.
Something like that:




Thank you!

 

The actual performance/memory/etc characteristics of that particular hardware. Most likely not feasible, but you asked

 

DPI/PPI, im not sure if thats handled

 

Make the return value of

Application.internetReachability

configurable in the simulator. This would allow me to test if my game detects internet reachability changes correctly and properly updates its UI.

 

Unstable and slow frame-rate simulation.

We have to support rather old mobile devices where the game is to be expected to run at 20fps from time and is overly stuttery, eg 200ms spikes when UI opens etc. This bad performance obviously never happens in the editor. So we had the problem that several "delta time" issues only occurred on the device.

We then implemented "random sleeps" on the main thread to poorly simulate this behavior in the editor. This helped us to detect various frame-rate depended issues in the editor, where we had to run on the device previously.

Our S***ty frame-rate simulation look like this:

Code (CSharp):

1. var threadSleepMin = Commandline.GetInt("-ThreadSleepMin", 0);
2. var threadSleepMax = Commandline.GetInt("-ThreadSleepMax", 0);
3. if (threadSleepMin > 0 && threadSleepMax > 0)
4. {
5.     var threadSleep = UnityEngine.Random.Range(threadSleepMin, threadSleepMax);
6.     System.Threading.Thread.Sleep(threadSleep);
7. }

 

Make

Application.systemLanguage

configurable in the Simulator. So I can properly test if my game picks up the correct system language on the first start.

 

Add simulation of device behavior like:
- switch to another app and go back
- press of power button to make device sleep and go back

 

With the latest version 1.2.0-preview which supports setting a customized device folder, you can copy/paste the existing json files to any folder and modify as you want. You can find the setting at Preferences->Device Simulator.

 

Are you using URP or HDRP? We have a bug with the shader we used in device simulator, we're working on a fix.

 

What kind of DPI simulation are you talking about? In this package, we considered the Fixed DPI option in player settings, you can set the dpi with this option on. Let me know if you're talking about something else.

 

Thanks. We discussed the physical size scale while developing, will have it in discussion again.

 

Bug report?

 

Do you have a place to enter the PPI as shown in the screenshot below?

 

Same thing im requesting
This will show our ugui different based on these devices with different ppis.
