Summary

Target Dummy Tracks and Target Dummy cause constant errors and stop working erratically

Steps to Reproduce

Add a few target dummy tracks to map. Run test session. End session. Repeat and save project often. Eventually you will get errors every time you save or try to push a new session. Also, when they do work in a session they will eventually stop working randomly in some future sessions.

Expected Result

Placed devices should work as expected and not cause errors.

Observed Result

Will get constant: “Illegal property modification: Property value differs from default” errors for all or most Target dummy Tracks and also Target Dummy devices. Also, the Target Dummy Tracks will not let the player knock them down in random sessions - this occurs when no changes were made to them.

Platform(s)

windows

Island Code

0000-0000-0000

Additional Notes

No code, non-published map.


Example of errors I get on all saves of the map. Some times the errors don’t appear but they will start appearing after a save or two again.

@PixelandPoly can you elaborate a bit on how the devices “stop working”? Thanks

Yes, This only applies to the ‘Target Dummy Track’ devices.

At some point during a new session the player will not be able to knock down the targets any more. This occurs when no changes are made to the player or the target settings.

The ‘Target Dummy Track’ devices move and look as expected, they just can not be knocked down. The ‘Target Dummy’ devices don’t stop working.

If I disconnect uefn from FN and close out uefn and reopen the project and then open a new session targets behave as normal for that first session anyway.

How did you fix this?

I would end up replacing a lot of them with brand new devices others would work on later sessions. No easy solution, unfortunately.

They give errors when saving on a non consistent basis still.

Hi! Did you check and repair it? I have the same problem

Still having this exact issue. In fact, after deleting the target dummies throwing the errors, I was left with random character references in my editor which I could not simply delete. I had to check everything into revision control, compile my editor, and only after receiving the error message was I able to finally delete these random character references that were still attached to already deleted target dummies.

Furthermore, I added 5 new target dummies and didn’t do anything to them and was immediately greeted by the Illegal Property Modification shown above.

Can you please keep working to fix this error as this minigame is a considerable part of the progress of my island.

Thanks
