Entities 0.8 Compile Error in android platform

Hello Unity!

there is a Compile Error when the Entities 0.8 Package and switching to Android platform.(reproduced in an empty project)

Errore:
Library\PackageCache\com.unity.entities@0.8.0-preview.8\Unity.Scenes.Hybrid\LiveLink\LiveLinkPlayerSystemGroup.cs(53,48): error CS0103: The name 'bootstrapFilePath' does not exist in the current context

Library\PackageCache\com.unity.entities@0.8.0-preview.8\Unity.Scenes.Hybrid\LiveLink\LiveLinkPlayerSystemGroup.cs(32,59): error CS0117: 'SceneSystem' does not contain a definition for 'GetBootStrapPath'

 

Found temporary fix:
Need to modify LiveLinkPlayerSystemGroup.cs and SceneSystem.cs

LiveLinkPlayerSystemGroup.cs

Spoiler: LiveLinkPlayerSystemGroup.cs Modification

In "LiveLinkPlayerSystemGroup.cs" (Library\PackageCache\com.unity.entities@0.8.0-preview.8\Unity.Scenes.Hybrid\LiveLink\LiveLinkPlayerSystemGroup.cs)

Move var bootstrapFilePath = GetBootStrapPath(); above #if UNITY_ANDROID
Before:

Code (CSharp):

1.         protected override void OnCreate()
2.         {
3. #if UNITY_ANDROID
4.             var uwrFile = new UnityWebRequest(SceneSystem.GetBootStrapPath());
5.             uwrFile.SendWebRequest();
6.             while(!uwrFile.isDone) {}
7.  
8.             if (uwrFile.isNetworkError || uwrFile.isHttpError)
9.             {
10.                 Enabled = false;
11.             }
12.             else
13.             {
14.                 Enabled = true;
15.             }
16. #else
17.             var bootstrapFilePath = GetBootStrapPath(); //<----- This (Line 45)
18.             Enabled = File.Exists(bootstrapFilePath);
19. #endif

After:

Code (CSharp):

1.         protected override void OnCreate()
2.         {
3.             var bootstrapFilePath = GetBootStrapPath(); //<----- To here (Line 31)
4. #if UNITY_ANDROID
5.             var uwrFile = new UnityWebRequest(SceneSystem.GetBootStrapPath());
6.             uwrFile.SendWebRequest();
7.             while(!uwrFile.isDone) {}
8.  
9.             if (uwrFile.isNetworkError || uwrFile.isHttpError)
10.             {
11.                 Enabled = false;
12.             }
13.             else
14.             {
15.                 Enabled = true;
16.             }
17. #else
18.             Enabled = File.Exists(bootstrapFilePath);
19. #endif

SceneSystem.cs

Spoiler: SceneSystem.cs Modification

In "SceneSystem.cs" (Library\PackageCache\com.unity.entities@0.8.0-preview.8\Unity.Scenes.Hybrid\SceneSystem.cs)

Add static internal string GetBootStrapPath() method and add k_BootstrapFileName string variable
Before:

Code (CSharp):

1.     public class SceneSystem : ComponentSystem
2.     {
3.         public const string k_SceneInfoFileName = "catalog.bin";
4.  
5.         static internal string GetSceneInfoPath()
6.         {
7.             return Path.Combine(Application.streamingAssetsPath, k_SceneInfoFileName);
8.         }

After:

Code (CSharp):

1.     public class SceneSystem : ComponentSystem
2.     {
3.         public const string k_BootstrapFileName = "livelink-bootstrap.txt"; //<------ This line
4.         public const string k_SceneInfoFileName = "catalog.bin";
5.         //This function below
6.         static internal string GetBootStrapPath()
7.         {
8.             return Path.Combine(Application.streamingAssetsPath, k_BootstrapFileName);
9.         }
10.         //-----------------------------
11.         static internal string GetSceneInfoPath()
12.         {
13.             return Path.Combine(Application.streamingAssetsPath, k_SceneInfoFileName);
14.         }

Tested using my current project, I'm not using LiveLink, so not sure if that's working, but it builds and runs successfully.

Edit: Just found out that packages revert themselves when you close then reopen the editor, so you have to modify these every time you reopen the editor

 

it works! thanks

 

Can you show me how to fix it "
Entities 0.8 Compile Error in android platform
Library\PackageCache\com.unity.entities@0.8.0-preview.8\Unity.Scenes.Hybrid\LiveLink\LiveLinkPlayerSystemGroup.cs(32,59): error CS0117: 'SceneSystem' does not contain a definition for 'GetBootStrapPath'


thanks

 

yes ...
its definitely horrible :[

 

Open the SceneSystem.cs and LiveLinkPlayerSystemGroup.cs files (by searching in the Project tab for "SceneSystem" and "LiveLinkPlayerSystemGroup" with In Packages selected), then do the solution I provided my previous post:

You have to change both files every time you reopen your project, until this is updated.

 

Or just move it to Packages folder from PackagesCache and it will made package local and would't change it automatically.

thanks for your sharing
it works for me.

 

Which one are you suggesting to move from PackagesCache to the Packages folder?

 

Most likely

Library\PackageCache\com.unity.entities@0.8.0-preview.8

?

 

Just reported this (case number 1232718)

 

If you're not interested about LiveLink functionality ( I'm not using it too ), you could only remove "SceneSystem.", just after #if UNITY_ANDROID.

The file then would looks like so:

Spoiler: LiveLinkPlayerSystemGroup.cs Modification

Code (CSharp):

1. protected override void OnCreate()
2.         {
3.          var bootstrapFilePath = GetBootStrapPath(); // <--as said, this is moved from below.
4. #if UNITY_ANDROID
5.             var uwrFile = new UnityWebRequest(GetBootStrapPath()); // <-- here the "SceneSystem." is removed.
6.             uwrFile.SendWebRequest();
7.             while(!uwrFile.isDone) {}
8.  
9.             if (uwrFile.isNetworkError || uwrFile.isHttpError)
10.             {
11.                 Enabled = false;
12.             }
13.             else
14.             {
15.                 Enabled = true;
16.             }
17. #else
18.          Enabled = File.Exists(bootstrapFilePath);
19. #endif
20.             if (Enabled)
21.             {
22.                 if (!UnityEngine.Networking.PlayerConnection.PlayerConnection.instance.isConnected)
23.                     Debug.LogError("Failed to connect to the Editor.\nAn Editor connection is required for LiveLink to work.");
24.              
25.                 using (var rdr = File.OpenText(bootstrapFilePath))
26.                 {
27.                     var buildConfigurationGUID = new Hash128(rdr.ReadLine());
28.                     LiveLinkSessionId = long.Parse(rdr.ReadLine() ?? throw new Exception("Expected line in bootstrap containing session id!"));
29.                     World.GetOrCreateSystem<SceneSystem>().BuildConfigurationGUID = buildConfigurationGUID;
30.                 }
31.             }
32.         }
33.  

 

annoying issue\\ 1 month and no official fix (

 

I think updating to 0.10+ should work

 

Im on 2019.3.14 f1 but project is old/ maybe smth happening with scripts or you mean downgrade to 2019. 0.10 / maybe its an idea

 

He meant updating the entities package to 0.10.

 

that helped no errors now ty nicolasgramlich brunocoimbra / for people like me with " alternative" brain entities 0.10 is in package manager
