Hi This is a very good project.

Whenever I load the fmu file, there will be a crash

I am very sincerely seeking help.

@xiaoyang666 thanks for bringing this to our attention.

It looks like we didn't add in the requisite .dlls - I have added them in. Can you check these out and let me know if this resolves your issue?

Additional note: We have the source/x64 third party libraries - fmikit, libzip, zlib - bundled for convenience. In some cases it may be necessary to obtain/build these from source.

@greenwoodms06 - One additional note, it looks like we get a crash when attempting to open a non-existent file. The project opens with the test.fmu from your local path. Presumably if a user picks a file and (re)moves it then tries to run there will be a crash rather than a helpful message.

@tnorby hmmm. Yes I think I came upon a similar crash too... was busy so I didn't think much about it at the time. Seems like we need to add some exists() check or something such that it fails elegantly on beginplay()

greenwoodms06 commented 3 years ago

@tnorby I added a simple catch to hopefully catch the common situation where the extracted fmu is missing

Thank you very much for your help. After the change, the running program does not flash back.

greenwoodms06 commented 3 years ago

@xiaoyang666 are you saying it works now?

xiaoyang666 commented 3 years ago

@ xiaoyang666您是说现在可以使用吗？

No problem at the moment. The task I am doing now is to import the Adams model into UE4 for real-time simulation of vehicle dynamics. Create a vehicle class parent class in UE4 and let FMU as a child class. This is my current idea, I hope it will work through this plugin.

@xiaoyang666 Excellent. That sounds great. We would love to know how it goes or see a demo of anything you use it for. I'll go ahead and close this issue.
