The search couldn't help me. In Island Defense 2 I use a model swap to switch the sentry with the dark sentry when a certain upgrade is completed with these actor events - and it works fine.

Upgrade.XXX.Add

Model Swap Dark Sentry

In another map I do the same, but this time with the zergling and the raptor strain - it doesn't work though. I also use an actor event for units that are not already made this time, since the Sentry is a hero unit and you will never get the upgrade without the Sentry already being there - but for the zerglings this is not the case.

ActorCreation

-> Validate Raptor Strain

Model Swap Raptorling

And this works - just not the swap on upgrade. I don't get it. Especially since it works fine on the other map and it seems to work for all the original blizzard actors.

So in short - when I get the upgrade, zerglings that are already on the map do not get their model swapped despite the actor event - newly trained ones have the new model.

Typical case of GalaxyEditor.png or am I doing something wrong?

Okay, I've been trying around for hours and I can't seem to find the issue. The sentry has nothing special about it and I can't remember adding anything to make the model swap work in particular. Yet it works for the Sentry but not for my zerglings (and by now also roaches - same issue).

I found the issue. You need to set the units affected in the upgrade in the "Affected Units Array" otherwise the actor doesn't get the Upgrade.xxx.Add message.

I forgot that this field in the upgrade actually had a purpose.

Yes.

I added a wiki entry for the upgrade event.
