Prop manipulator doesn´t work with spawned props

Development Programming & Scripting Verse

I am prototyping a Fortress defense map, where I have an amount of custom enemies spawned at runtime and running to my tower. In order to count the player eliminating the enemies I placed a prop manipulator in the scene to trigger the DestroyedEvent().

The device works perfectly with objects already present in the scene, but it fails to trigger the event with the enemies I have spawned at runtime. I don´t know if this is a bug or the device only works with props that are already in the scene.

If anyone could shine some light on this it would help me a lot.

Spawned props are creative_prop_assets so maybe it doesn’t work?

I actually generate a list of creative props when spawned. I dont know if it may be because they are of type ?creative_prop (According to documentation)

Prop manipulators and prop movers are assigned a prop on game start. So I’d say that, you’re right! It can’t work that way.

What you could do is to not spawn those props in Verse but rather place them in your map (hidden somewhere), and teleport them on round start.

If your number of prop is dynamic, then you’ll have to do some more code :shrimp:

I might be wrong, but that’s what I concluded when doing my tests, but you can go ahead and try yours.

Yes, what I have ended up doing is a loop where I check the IsValid attribute for each prop in the array. This way I know if the player has eliminated an enemy.

This is actually smarter than what I told you, gg!

I am trying to do something similar. However, my spawned props seem to be invulnerable (they don’t break when shooting them). How did you manage to use the IsValid attribute?

In my case I was using custom props with a skeletal mesh and animation. I had to create a blueprint and set it up, there are plenty of tutorials around that show you how to do it. For me I didn´t have to do anything special to delete them from the scene, just shooting at them. (Check you have everything set up correctly)

The way I used the IsValid attribute was in a loop, just to check if the prop is still in the scene. If it´s not valid that would mean the player eliminated the prop if that makes sense, so I would update the score.

I’d be interested to know how to make a blueprint prop destructible and setting its health. Without using a prop manipulator.

Thanks

I cover part of that here, skipping past the creation of the prop

Thanks for the video. There is something weird with the SpawnProp function in verse. It seems to remove the flag “can be damaged” from the blueprint.

Finally coming back to this, I agree, seems to remove the ability to destroy the prop

You’re totally right there. I found out the best solution is to place them inside the manipulator volume, and disable “Is Spatially Loaded” if you’re working with assets streaming, otherwise teleporting them might not work if they’re not loaded.

hi I have same issue, with spawned prop not being able to take damage no matter that I do, did you find out a solution? thanks

This is still happening as of 2025.

It would be essentially important to have an update on this device, since the maximum amount of spawned props was increased in a recent update.

My game spawns hundreds of props on a Grid, and checking isValid becomes very costly, so I need to limit the checking to locations close to the player. However, this limits some gameplay functions, preventing me from using explosives from a distance, for example.

Another possible update would be a DestroyedEvent directly in the creative_prop, which would solve the performance problem as well.
