Generic error message in Rhubarb for Spine

[DanielSWolf]

When Rhubarb Lip Sync for Spine is run from a JAR file (as opposed to a .class file), it fails to determine its binary directory. This results in the generic error message "Error performing lip sync for event ."

To fix this, a more robust may of determining the binary directory needs to be implemented.

Hello) I have a I have a problem

Thanks for any help

[DanielSWolf]

@Sergmarshall: Please let me know what operating system and what exact version of Rhubarb you're using.

In addition, please do the following:

• Open a command line window
• Navigate to <rhubarb>/extras/EsotericSoftwareSpine
• Run java -jar rhubarb-for-spine-<version>.jar
• Reproduce the error
• The command line window should now contain a stack trace. Copy and paste the stack trace into your answer.

I think I found the problem. If my understanding is correct, this error occurs if the JSON file doesn't contain at least one animation. As a quick workaround, create an empty dummy animation in Spine, re-export to JSON and try again.

Let me know if that fixes the problem. If so, I'll create a bugfix release.

[Sergmarshall]

I made some animations and everything is the same and with empty dummy animation

I'm afraid I can't reproduce the error you're getting. My guess is that there's either something unexpected in your JSON file, or your JVM behaves differently from mine.

Could you attach the Spine JSON file you're using, along with all images and sound files? Just create a ZIP file with the entire directory structure. This should help me reproduce the behavior you're getting.

Also, could you tell me the exact JVM version you're using? (Execute java -version)

Hi,

Getting same error / stack trace too.

Update:
It works if in Spine you add the dialog text to the String property of the event (in setup mode). I thought this was optional so had left it out..

[DanielSWolf]

Thank you for the detailed information! I'll fix this as soon as I find some time. And, yes, the dialog text should be completely optional!

[DanielSWolf]

I found the problem! It is a bug in my code (as expected). The real mystery was why it works on my machine. Turns out it's a bug in the programming language that would make it work in some cases, when really it should always have failed. I'll have a fix ASAP.

[DanielSWolf]

I believe I've fixed the issue. @Sergmarshall, @rich-earth: Please replace the JAR file in your Rhubarb installation with the JAR file contained within the attached ZIP file. Let me know whether that fixes your problems! If so, I'll make an official bugfix release.

rhubarb-for-spine-1.7.1.jar.zip

[Sergmarshall]

the plugin is working!
thank you!
