How to track destroyed creature spawners?

Is it possible to have a tracker for destroyed creature spawners?
I don’t want to count the eliminated creatures itself but the spawners, as a goal of my game would be to destroy all 40 creature “nests”(=spawners)…
Besides that, I have 4 guards hat need to be eliminated, so I want to track/count those 4 too…
I was able to make a tracker for my coins with custom hud, but the other 2 goals, I am stuck…
I have made the trackers and their hud but don’t know how to connect the trackers to the 40 creature spawners and the 4 guards…
Besides that the tracker huds tend to disappear after a while. They also suddenly were not as bright as a few days ago. But I see no option to change brightness.
Not sure how that happened. Also my post process is not enabled when launching from UEFN.
As soon I quit the game it appears and when I restart the game post process works…

EDIT
The creature spawners get counted when I use “Prop Destroyed” but every other prop will be counted too. So, can I determine which prop to count?

EDIT
I made everything except the spawners indestructible, so this might work.
Though now I have another issue, coins raise without a reason! 64 out of 20 :wink:
In the second image you also see the brightness issue of the huds, two are bright, one is fade, at game start all 3 were fade.
And weirdly the coin pic on tracker is bright, text not…
And tracking elimination of guards (wildlife/creature mode) does not work, neither with elimination nor eliminated…

Hey,

Use the tracker to track events, then use the guard elimination trackers increment function with the guard spawners on eliminated event.

Same for coins, use events and track the collectibles on collected event.

The creature spawner if its counted as prop destroyed, then it should work with a prop manipulator, Drop a prop manipulator over each creature spawner, use the zone settings, they work better, make a little box around each one.
Then track the event of each of the 40 prop manipulators on destroyed event.
