Oliver Iking 3 years ago • updated by Lazlo Bonin (Lead Developer) 3 years ago • 7 • 1 duplicate

Windows Standalone x64 Build, Bolt 1.4.3, reproduced on Unity 2018.3 and 2019.1

Bolt seems no longer be able to deserialize graphs at runtime:

Failed to deserialize behaviour.
System.Runtime.Serialization.SerializationException: Deserialization into 'Bolt.FlowMachine' failed. ---> System.PlatformNotSupportedException: Operation is not supported on this platform.

I have a very simple reproduction project at hand:

BoltNotRunningAtRuntime.zip

Just add Bolt 1.4.3 to it.

- In the editor, open "Boot", press play. A flow graph will automatically load the scene "Second"
- Make a Windows x64 standalone build
- Start the build. Build will be stuck in the "Boot" scene

Bolt Version:
1.4.3
Unity Version:
2018.3 / 2019.1

Scripting Backend:

I replaced 1.4.3 with 1.4.0f11 and it works again, so that's probably a regression?

Edit: 1.4.2 also still worked, so that's good news for me because I can easily downgrade ;-)

Same here (https://support.ludiq.io/communities/5/topics/3129-bolt-143-runtime-broken)

Working on Fix
Lazlo Bonin (Lead Developer) 3 years ago

Hi Oliver,

Are you building for standalone using the IL2CPP runtime? If so, I think that may be the issue. The check to detect whether Bolt is running on IL2CPP changed in 1.4.3, and might be too permissive now.

You can check this here:

Either way, I'll look into fixing this ASAP and maybe even issuing a hotfix (1.4.3f2).

Oliver Iking 3 years ago

The repro project runs on Mono, which makes this really puzzling for me.

Lazlo Bonin (Lead Developer) 3 years ago

Interesting. I wonder if they removed JIT support from standalone altogether in recent versions. Will do some tests.

Fixed in Hotfix
Lazlo Bonin (Lead Developer) 3 years ago

I'm temporarily disabling JIT on all Standalone builds, even Mono, until I figure out what changed in the underlying Unity API that makes System.Reflection.Emit fail on this platform. This will be pushed in a hotfix, v.1.4.3f2, which I'm uploading now.

This is obviously a small drawback for performance, but most of the performance optimizations of Bolt are intact, as we can still convert reflection calls to delegates.

v.1.4.3f2 available here: https://ludiq.io/bolt/download/1.4.3f2
