Thank you Kevin,

the bugfix in version 14.10.29 solved our issue. It’s working fine now!


We were using GME 14.10.10. Sorry for any inconvenience.

What version of GME are you using? There was a bug fixed in 14.10.29 that prevented addons from getting some events.

Hello everyone,


We have an issue with GME-Interpreter working as Add-On.


What we want to do:

Set an Objects Registry-Value “nameColor” according to this Objects Attribute named “Color”.



It works fine for the FIRST time, but when we change the Attribute a second time, nothing happens (the Interpreter doesn’t start at all).

After restarting GME it works, but again just for one time.


You’ll find our Interpreter-Code attached.



If we comment the lines where Registry is set, the Interpreter works even several times (but nothing happens in the model for sure).

otherFCO->getRegistry()->setValueByPath("/nameColor" , "0xff0000");



Any idea?

Thanks in advance.
