Bug: Behavior with Bootstrapper (response to jhmaverick)

Hey @jhmaverick,

You posted on a different thread which is now locked so I moved the thread here. Original post:

Behavior Package 1.0.1 is released! Update: 1.0.3 is out

Sure, you can reproduce it by following these steps: Create a new project (in my case, I used Unity 6000.0.24f1). Install the Behavior Demo package. Add the SceneBootstrapper script. Check if the “Bootstrapper” scene is the first in the Scene List. Open a different scene, as the script will not run if it is already loaded. Press play, wait a moment, and then press stop. Close the project and open it again (the issue can happen without restarting, but restarting increases the chances). Press pl…

• Create a new project (in my case, I used Unity 6000.0.24f1).
• Install the Behavior Demo package.

• Check if the “Bootstrapper” scene is the first in the Scene List.

• Press play, wait a moment, and then press stop.
• Close the project and open it again (the issue can happen without restarting, but restarting increases the chances).
• Press play again, and the errors should start to appear, with several NullReferenceExceptions showing up in the console.

Thanks!

I’ve investigated it and as you found out, the bootstrapper modifies the isPlaying parameter which I believe interacts badly with RuntimeBlackboardAsset because UnityEditor.EditorApplication.isPlaying is now false. I’m looking to see if there is an alternative way to handle the situation for RuntimeBlackboardAsset in this case, this will unfortunately not be out today.

Hi, @ShaneeNishry,

No problem! After I commented out those lines, it’s working fine for me. I decided to report it because it might happen to other people using a script with similar behavior.

Thank you for your attention.

Hi jhmaverick,

Thanks for reporting the bug, we have created a public issue for it (should be visible in a few days): https://issuetracker.unity3d.com/product/unity/issues/guid/BEHAVB-9

BootStrapSceneLoader.cs (842 Bytes)
You could just use this very simple version that just makes sure the Bootstrapper scene is loaded no matter which scene you have opened in the editor.
The comment above the OnFirstLoad method is a bit quirky since I pulled this from here and modified it to just handle the initial loading of the Bootstrapper.

I tried using the script, but since I’m using VContainer, I get a lot of errors until the bootstrap scene is loaded. I think opening the scene during ExitingEditMode is still the best option.

SceneBootstrapper.cs (6.3 KB)
Could you try this modified version of the SceneBootstrapper and let me know if it resolves your issues?
(It seems to resolve the issues regarding the replication steps but just making sure)

With this script, it worked perfectly.
