Bolt 2 A10 Setting graph variable in function breaks C# generation

Reality.Stop() 2 years ago • updated by Lazlo Bonin (Lead Developer) 2 years ago • 9 • 1 duplicate

Create a Flow function and add a graph variable.

Set the graph variable.

Check C# generation.

Getting the variable works fine, and uses the variable value as normal:

Bolt Version:
Bolt 2a10
Unity Version:
2019.3.2f1
Platform(s):
Windows
Scripting Backend:
Mono
.NET Version (API Compatibility Level):
.NET 4.x
Bolt 2 GFI

Can confirm, also happens on my end:

The following errors occured while generating scripts:

As a side note - deleting the graph variable doesn't mark the set graph variable units still present in the graph as red/missing.

Hi Matthias,

Sorry for the late reply and thanks for the report.

I'll look into this, there has been many similar reports over the last few days.

Hi everyone,

Thanks for the report, I'll have to look into what may be causing this, but it seems like I forgot to alias the graph variable in the local function body generator.

Cannot Reproduce
Lazlo Bonin (Lead Developer) 2 years ago

Hi everyone,

I can't get this to reproduce on my end. It works fine here.

I had assumed I might have fixed it already in another commit, but even reverting to Alpha 10, I can't get it to occur.

Is there any more specific information needed? Any particular type of variable, or anything particular about the flow function?

Ex-Crow 2 years ago

I can't reproduce it either anymore. 

Reality.Stop() 2 years ago

I'll see what I can get tonight.  I haven't been able to create a graph variable successfully yet, so I should be able to create a repro.

Reality.Stop() 2 years ago

Easy for me to induce!

Nothing funky, bare class with the function you see here.
