How to add a debug filter?

What do you mean? The one in the toolbar or you’re talking about writing a custom debugger?

The one in the toolbar has a drop down that lists actor instances; run the project, pick an actor instance from the list and it will be monitored for events.

I see, i should describe my problem a bit more.
Yes, i mean that one in the toolbar but when i turn that on and run the project, the “watch values” objects keep staying at x=0;y=0;z=0;.

If this is inside of a function, it’s probably simply not in scope - not sure if this engine limitation, bug or simply a missing feature. It normally does work when in the graph.

objects keep staying at x=0;y=0;z=0;.

Did you select it in the filter?

If in doubt, attach a screenshot.
