[Code Plugin] Feedback Event Factory

[sweetdardo]

@Ryan_Darcey

The 4.23 update is now live!

This includes a significant optimization pass that opens up new “Fast” spawn variants. The TLDR is that these new “Fast” variants don’t spawn a new Feedback Event Factory actor; they just spawn the events associated with the factory and populate a struct handle (FActiveFactoryInfo) with information about the newly spawned events.

I did my best to ensure that there would be minimal work required to upgrade to this new version, but please note that this update may require some changes to your project. Specifically, info about active events (e.g. audio components, particle system components, etc.) now live in a FActiveFactoryInfo struct on the Feedback Event Factory rather than directly on the Feedback Event Factory actor itself.

More details on how to simply spawn these “Fast” variants can be found here:

Hello Ryan,

I have being on an older version of UE for a while and while updating to 4.23, I have a repro crash out of PIE play session or in build with Feedback Factory plugin mentioned. I implemented some simple events on Hit so that I have rumble, some camera shakes. It always crashes whenever a FFevent is triggered (after a few 2 /3 to be clear).
Since you mention some changes in 4.23, I do not remember having to add anything on begin play previously, it could just be that or somethign else?
This is the crash log:
