Official Project Tiny Fall update “Tiny Racing" preview.3 - 020.0 is available

i kind of figuring out why my modification does not take effect, according to ConvertMaterial.cs

Code (CSharp):

1. Entities.ForEach((UnityEngine.Material uMaterial) =>
2.             {
3.                 var entity = GetPrimaryEntity(uMaterial);
4.                 switch (uMaterial.shader.name)
5.                 {
6.                     case "Universal Render Pipeline/Unlit":
7.                         ConvertUnlitMaterial(entity, uMaterial);
8.                         break;
9.                     case "Universal Render Pipeline/Lit":
10.                         ConvertLitMaterial(entity, uMaterial);
11.                         break;
12.                     case "Sprites/Default":    // Sprite material conversion is handled by Unity.U2D.Entities.MaterialProxyConversion
13.                     case "Universal Render Pipeline/2D/Sprite-Lit-Default":
14.                         break;
15.                     default:
16.                         UnityEngine.Debug.LogWarning("No material conversion yet for shader " + uMaterial.shader.name);
17.                         break;
18.                 }
19.             });

there are only four shaders supported so far, still, i would like to know if it is possible to change the build-in shader or use one of my own.

 

thanks for the reply, right now i am developing tiny games embedded within apps like facebook instant game. while i manage to run the html version of tiny3d on that platform, i encounter some render problems. One of the problems is that the pictures seem to render a lot more brighter than they actually are. Here are screenshots illustrating the problem:
1、pc web


2、mobile embedded web


it seems to be the problem of picture color space, i look up the reference of glTexImage2D on opengl es 2.0
https://www.khronos.org/registry/OpenGL-Refpages/es2.0/xhtml/glTexImage2D.xml,
it seems glTexImage2D on opengl es 2.0 does not support GL_SRGB, so the problem should be webgl load the pictures without transforming them into linear space.
therefore, i try to parse the pixels to linear space before further processing by editing the shader.
however, it seems tiny builder would not rebuild the shader files when building.

 

Following the above reply,


finally, i have to manually change the gamma value of the pictures to make them darker to event the gamma correction, here are the result:




it looks a lot better than the previous result in mobile embedded web, but i think this is not a perfect method since pictures are not always in SRGB color space.

what do you think of this problem? how would you suggest to solve this problem? thanks

 

Thank you for your reply.
I think the game's playable ad is trending and facebook is also a very strong platform in online advertising.
I'm really glad if the tiny project support for facebook ads as soon as possible.
Thank you.

 

@AbdulAlgharbi
Using entity framework 0.4, getting the following in a webgl dots runtime build, both chrome and firefox, any ideas? Another user reported it earlier in this thread with no reply, basically it's failing to load the serialized scene. I'm hosting this on IIS, and added the application/octet-stream mime type for any file that doesn't have an extension. Is this the correct way?

Edit: further info,I downloaded the served serialized file through the browser and did a SHA1 checksum on it, compared it to the original file generated by the unity build, same checksum, so mime type doesn't seem to be the issue. I think. What else can I do?

Edit2: FIGURED IT OUT!
For anyone else having this issue: so this error happens when your serialized scene contains componentdata that exists in a separate asmdef. You need to make sure the root assembly definition of your dots runtime build references all the asmdefs that contain data types you use in your scene. Unfortunately, Tiny won't tell you what those data types are that it can't deserialize, by default, because the error that would tell you what the data type hash is is inside an exception throw, and Tiny doesn't support exceptions.

However, you can do this:
Modify com.unity.entities@0.4.0-preview.10\Unity.Entities\Serialization\SerializeUtility.cs ReadTypeArray(BinaryReader reader) method at line 263.
Right where it throws exception add these two lines right above it, like this. Rebuild and watch the console in the browser spit out the hash of the missing type. Then look it up inside your build folder, under Logs/SceneExportLogs.txt, where it lists all the types, and their hashes. It will tell you what type it can't deserialize, so you can add the asmdef reference to your core asmdef. Hope this helps someone.

@AbdulAlgharbi Maybe the way this is reported, or rather the way it's not reported now, could be improved in the future?

Code (CSharp):

1. private static NativeArray<int> ReadTypeArray(BinaryReader reader)
2.         {
3.             int typeCount = reader.ReadInt();
4.             var typeHashBuffer = new NativeArray<ulong>(typeCount, Allocator.Temp);
5.  
6.             reader.ReadArray(typeHashBuffer, typeCount);
7.  
8.             var types = new NativeArray<int>(typeCount, Allocator.Temp);
9.             for (int i = 0; i < typeCount; ++i)
10.             {
11.                 var typeIndex = TypeManager.GetTypeIndexFromStableTypeHash(typeHashBuffer[i]);
12.                 if (typeIndex < 0)
13.                 {
14.                     var typehash = typeHashBuffer[i].ToString();
15.                     Debug.LogError($"Cannot find TypeIndex for type hash:" + typehash);
16.                     throw new ArgumentException($"Cannot find TypeIndex for type hash {typeHashBuffer[i].ToString()}. Ensure your runtime depends on all assemblies defining the Component types your data uses.");
17.                 }
18.  
19.                 types[i] = typeIndex;
20.             }
21.  
22.             typeHashBuffer.Dispose();
23.             return types;
24.         }

Hi
I try to build Tiny Racing project but I got error Build Windows-DotNet failed in BuildStepRunBee after 3.59s. I try to remove dots-editor-tools follow this instructor. but it still not work. anyone have a solution for this?

 

Hi AbdulAlgharbi,
Thank you for your answer. I already install Desktop development with c++, .NET desktop development. and it still not work.

 

I can not find Tiny in Package Manager and I'm sure preview is checked.
I tried version 2018.4.6f1, 2019.3.0b3, 2020.1.0a16.
Could someone help me?

 

I can't find it either. so I use TinyRacing to be base project for my study

 

I tried to call

SendMessage("aaaaaa")

from browser's console to send message to unity from html page but got error:

ReferenceError: _SendMessage is not defined debugger eval code:89:13
_sendMessage blob:null/fa0ce938-46aa-4714-9e3a-84ab8c6c3620:95
<анонимный> debugger eval code:1

TinyRacing.js file in Builds folder contains

_SendMessage(messageOnHeap, intOnHeap.byteOffset, intArr.length, floatOnHeap.byteOffset, floatArr.length, bytesOnHeap.byteOffset, byteArray.length);

call but I can't find where this function is defined.

How can I send messages to Unity build from JS?

 

It seems

SendMessage

function from \com.unity.tiny.web@0.20.0-preview.2\Runtime\Unity.Tiny.Web\cpp~\SendMessageCallbackHandler.cpp is stripped from build.

Found workaround by removing package com.unity.tiny.web@0.20.0-preview.2 from packages and moving to Assets.
Then I added

EMSCRIPTEN_KEEPALIVE

after

DOTS_EXPORT(void)

for

SendMessage

in SendMessageCallbackHandler.cpp file.

 

Is it possible to output a single HTML file with the current version of Project Tiny?

 

Hello I tried out Project Tiny 3D and Tiny Racing to export with wasm and asmjs for the web, tested with Unity 2020.1.0a18.2166 and 2019.3.0f3, exporting was without problems.
I tested on Chrome, Edge and Opera to open the compiled project and received:

Tiny3D.html:7 Access to XMLHttpRequest at 'file:///D:/Projekte%20aktuell/Unity/ProjectTinySamples-master/Tiny3D/Builds/Wasm-Tiny3D/Tiny3D.js' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.
(anonymous) @ Tiny3D.html:7

I also used this batch code to open the html file:
start chrome.exe "%cd%/Tiny3D.html" --allow-file-access-from-files

The Screen is white, only Edge is showing a black screen with a dashed line on the borders.
What should I do to resolve this issue?

 

i try to import js libs flowing the manual:
https://docs.unity3d.com/2020.1/Documentation/Manual/webgl-interactingwithbrowserscripting.html
it works fine when build for webgl, but it failed when build for tiny wasm, and i got this error:

Build Wasm-Tiny3D failed in BuildStepRunBee after 7.17s.

warning: unexpected return type i8* in call to 'SetTempSliceHandle', should be void

warning: unexpected return type i8* in call to 'SetTempMemSafetyHandle', should be void

warning: unexpected return type i32 in call to 'Close', should be void

error: undefined symbol: Hello

warning: To disable errors for undefined symbols use `-s ERROR_ON_UNDEFINED_SYMBOLS=0`

Error: Aborting compilation due to previous errors

it seems the way of importing js libs from the manual does not work for tiny wasm, what is the correct way to import js libs for tiny wasm

 

Make a folder "js~", put .js library into it. Place the folder and the script which interacts with js next to asm.def.

https://github.com/MartinKral/tiny-one-button/tree/master/Assets/Scripts/Main/Utils/URLOpener

 

thanks a lot man, it works! another problem, since tiny wasm build does not contain a unityInstance plugin, how can the js call back to the c# script function

i guess i can use the _sendMessage to call unity script function, but i can not find the definition of _SendMessage, and it failed when i try to call _sendMessage

Code (JavaScript):

1. var _sendMessage = function (message, intArr, floatArr, byteArray) {
2.         if (!Array.isArray(intArr)) {
3.             intArr = []
4.         }
5.         if (!Array.isArray(floatArr)) {
6.             floatArr = []
7.         }
8.         if (!Array.isArray(byteArray)) {
9.             byteArray = []
10.         }
11.         var messageOnHeap, intOnHeap, floatOnHeap, bytesOnHeap;
12.         try {
13.             messageOnHeap = _allocateStringOnHeap(message);
14.             intOnHeap = _allocateArrayOnHeap(new Int32Array(intArr));
15.             floatOnHeap = _allocateArrayOnHeap(new Float32Array(floatArr));
16.             bytesOnHeap = _allocateArrayOnHeap(new Uint8Array(byteArray));
17.             _SendMessage(messageOnHeap, intOnHeap.byteOffset, intArr.length, floatOnHeap.byteOffset, floatArr.length, bytesOnHeap.byteOffset, byteArray.length)
18.         } finally {
19.             _freeStringFromHeap(messageOnHeap);
20.             _freeArrayFromHeap(intOnHeap);
21.             _freeArrayFromHeap(floatOnHeap);
22.             _freeArrayFromHeap(bytesOnHeap)
23.         }
24.     };

 

Thank you for your Answer!
I also tried it with a webserver, but it still doesn't work:
https://light-and-dance.com/Apps/ProjectTiny/Tiny3D.html

getting this on chrome:


and this on Edge:


Do you know what can cause this?
I really appreciate your help!

 

I set it to 1024 (256 looked like beeing not enough):


And receiving this on chrome:



you can test it yourself here:

I don't get it. I'm trying the Tiny3D instead of TinyRacing

I open the Tiny3D scene. It plays fine in editor it seems. Shows little island with turning windmill, clouds, all on a turning Island. I go to the builds folder, select "Wasm-Tiny3D". Upper right I click "Build and Run"

It gives me bunch of web based files, which I stick on my webserver online, I load the Tiny3D.html file, but it results in a blank white screen. Doesnt seem to load anything :-(

Also, in editor I get this:


I'm building with Unity 2020.1.0a19

EDIT:
Just tried building TinyRacing and copying the files over to my live server. Same result as Tiny3D. Just a blank white screen without anything seeming to load :-(

Tried on PC with Edge Browser, and also tried with Firefox 72.0.1 (64-bit). No errors, just white blank screen

EDIT2:
Just tried Asmjs instead of WASM, same result. Blank white screen. What am I doing wrong or missing?

 

I get this error:


What do I do with that error now?

Also, to future proof, should we be using asmjs or wasm?

 

Configuration:

Where can I send the logfile to you?

 

I faced this issue. Workaround described here https://forum.unity.com/threads/pro...020-0-is-available.792999/page-3#post-5368830

 

We're considering using Tiny mode for our next project and I've been doing some prototyping.
I've been trying out different things that are necessary for our project, but going through all of them and making a prototype myself just to see if project Tiny is viable would take a lot of time.
There was a roadmap created in mid 2018 for project tiny that listed 'landed' features and features that are not supported or still in development.
Is there an update version of a document like that which shows clearly which unity features and functionalities are and aren't usable in 020.0 preview?

One of the issues I haven't been able to solve at this point is displaying transparency on materials attached to a quad or displaying a sprite correctly.
The project I created was based on the 'Tiny3D' sample project and I just added my own objects to the scene.
I tried 3 different ways of displaying a character from a png file with proper transparency, but none of them worked.

1. Set the image to Texture Type: Sprite (2D and UI) and use a sprite rendered in the scene => The image would display correctly in the editor but would not display at all when building it out and playing in the browser

2. Leave the image on Texture Type: Default, but check Alpha is Transparency. Then make a material from it and attach it to a quad. On the material I tried both the Universal Render Pipeline/Lit and Unlit => Displays correctly in editor but the game won't even load up in the browser. Would get stuck at the green screen with an error of 'No primary surface renderer node' and 'No camera in scene'.

3. Leave the image on Texture Type: Default, but not check Alpha is Transparency. Instead I made sure to select the Universal Render Pipeline/Unlit and use Surface Type: Transparent. => Same green screen issue.

In the Tiny Racing sample i can see quads that have a png attached to it with the same settings that I used, so project tiny should be able to support this functionality. However it seems to me there must be a very specific way of making this work and if you only do one thing differently everything breaks. The biggest problem here is also that it displays properly in the editor, but once I build it out nothing works which introduces many steps to trying out different approaches.

Does anybody have any suggestions to fix this issue?

Edit:
I somehow got it to display correctly not only using the same settings as the fake ui in the Tiny Racing example, but by also using that project as a base and importing my images in there instead of using Tiny3D as the base.
I guess there is a difference in some settings with the projects?

 

I think the trick is Default Texture with material: Unlit, Transparent, RenderFace: Both

 

I seem to be getting same issue as HECer

Sooooo trying to file a bug report from within Unity:


Previewing the report before I send, results in the Bug Reporter crashing. That is hilarious. The bug reporter crashes when trying to report a crash bug

 

When can we expect a fix for the problems we ran into?

 

Hi, is there a tutorial or guid on how to create a new game from start to finish?
I found some but they are for previous versions and are not relevant anymore

 

That's right. Currently now it not publish as package in the manager. You can only use the tiny project as template and start from there

 

So, i'm confused, i come back to Unity after a year without touch it, and then i see all these new concepts about Tiny, DOTS and ECS. And videos i found on it are all already obsolet (I'm using version 2019.3.2f1). I finally followed this guide, and succeeded to run TinyRacing and tiny3D samples. I'm not afraid to learn new concepts and understand the interest of tiny, but some questions come to me:

- Will tiny solution gradually replacing totally standard unity flow for making mobile games? In others words, can i choose to go definitively to this direction.
- When must i today choose to use tiny or not(my main purpose is to make mobile apps and facebook instant game)?
- Is it today enough stable to making production games with it?
- Does the manner to do tiny games change at every new tiny package version?
- Where can i find a good place to learn this new manner to do? except this guide of course. What is the best way to learn today that solution?

I know, that's a lot of questions and i've certainly others to explain my confusion. I came back to Unity with the intention to quickly make little games with the knowledge that i've already have through many formations, but with all these changes I don't know where to start anymore without spend to much time.

Any good advices?

 

Thanks a lot elliotc-unity, for your answers very clear and precise !
