How to make a reverse "switch on enum" macro?

Right, it does work! Thanks

But from the CustomNodeProject that you uploaded, how exactly do I compile this plugin for future engine versions so I don’t need to ask here every time a new version is released?

copy it over to the c++ version of a project into the plugin folder (you need to create it). Compile the basic project => open the plugins panel, enable the plugin. Once enabled you can see an option to pack the plugin on the bottom left of the plugin’s panel.

Then you can copy the packed version to the engine folder to use it with blueprints.

This worked perfectly, thanks.

now, sort off topic, sort not, but I’ve asked before and nobody answered, so if that’s not asking too much, could you help me packaging this open source plugin?

I’ve created a new c++ project, created a plugins folder inside of its root, downloaded this plugin from github and pasted the folder inside the “plugins” folder, generated visual studio files from my .uproject, ran the project from visual studio, went to the plugins window and clicked packaged. however it fails

Lots of plugin packaging seem to fail from 5.3 upward.

I’ve noticed that it does create a host project on pack. Maybe it packs the client version ok but for some reason tries to pull in portions of the editor? (might be a bad/ deprecated target setting)

So I need to recompile this plugin for 5.5 and I’m getting an error on packaging it, and I have absolutely no idea what’s going on.

I was afraid something like this would happen, now I rely on being able to recompile this plugin in order to update my game’s engine version.

any ideas how to fix?

Maybe you have the wrong IncludeOrderVersion set in your target files? (needs to be Unreal5_5)

My 5.5 version packs ok. Just make sure you pack it onto your target project separately from the plugins window.

fael097 · December 12, 2024, 3:04am

Somehow it doesn’t work. I downloaded your project and when packaging I get this:

3dRaven · December 12, 2024, 8:55am

Are you running vs and unreal as admin?
Seems like you have insuficient access from the warning message.

Things to look into:

Did you install the 5.5.1 hotfix?
Have you updated your msvc?
Does a default project compile correctly?

fael097 · December 12, 2024, 1:49pm

So I think the deal is, I had perforce installed, and just the other day I updated windows to 24H2, which totally broke perforce. so I had to uninstall it, but it had every file in my main project set as read-only.

it’s weird cuz I wasn’t using version control with the plugin project, and even though I unchecked read-only for everything in that project, I suppose perforce also got something in the unreal engine folder as read-only.

so I uninstalled everything, UE 5.4, 5.5, epic launcher, visual studio, and then installed everything again. VS is a PITA so I followed these tutorials:

and Setting Up Visual Studio Development Environment for C++ Projects in Unreal Engine | Unreal Engine 5.5 Documentation | Epic Developer Community

hit a brick wall since there’s no Visual studio integration tools for UE 5.5 yet, but then searching online people said you don’t really need that, so I went ahead with everything fresh, and it compiled somehow.

can’t pin point what exactly was causing the error, but it works now.

thanks again for helping out every time something comes up!

Unreal can be a finicky beast Glad you got it running on your end.
