Sorry, spine-cpp (that spine-ue) in the 4.2-beta branch is currently a WIP. We will have it working in the next few days, as we will release 4.2 as non-beta soon!

Cream The spine-cpp and the spine-ue runtime have been updated to use skeletons created with Spine 4.2-beta! It also supports physics as shown in the video below:

May I ask if your project is spine-runtimes-4.2-beta on Git？
I downloaded this project，But it say:

vs Error:
SkeletonJson.cpp
C4703 Potentially uninitialized local pointer variable 'keyMap' used

@jackar Sorry to hear you're having troubles. Please always post the complete unabbreviated compile error message. Your message is missing important details like the line number.

jackar Yes, the video I uploaded was recorded by importing celestial-circus into the SpineUE project in the 4.2-beta branch of the spine-runtimes repository.

The error message you uploaded is actually one that I have seen many times, but this error message is quite vague. As far as I know, the error is caused by the following factors:

• The spine-runtimes/spine-cpp/spine-cpp folder is not correctly included in Plugins/SpinePlugin/Source/SpinePlugin/Public/. (This procedure is also required even if you open the official sample project.)
• "SpinePlugin" is not included in the PublicDependencyModuleNames in the Build.cs file of your project.
• Your installed version of Visual Studio or Xcode is not compatible with UE5.3.

I hope this helps you.

Misaki
I apologize for my vague description earlier. Let me detail my experience.

First, I used spine-runtimes 4.1.00 on GitHub. Then, following the official documentation process, I opened it with Unreal Engine 5.3.2. It was able to compile successfully and run perfectly.

Next, I will attempt to use spine-runtimes 4.2Example on GitHub, because I noticed that only this project contains "celestial-circus".

I am using Windows 11, Unreal Engine 5.3.2, and Visual Studio 2022 17.9.4 .
I have prepared according to the official procedure:

Then I right-clicked on SpineUE.uproject to generate SpineUE.sln, and opened SpineUE.sln to run Local Windows Debugger, the following error popped up:

Then I opened SpineUE.uproject, and the same error occurred.

I'm not sure if my description is detailed enough, please contact me if you need more details. I hope to use the physical effects of spine4.2 in the Unreal Engine as soon as possible. Thanks for the reply!

Apologies! It looks like UE added a new set of "this warning is now an error" compiler flags. Please pull the latest changes from the 4.2-beta branch, and make sure you also update your copy of spine-cpp in the UE project.

Thank you for your kind words! I have employed the 4.2-beta version, which functions flawlessly!
