Logic Brick 'Property' fields with that black 'dot'?

I know we were told to not build anything with the BGE because it will change a lot in 2.8 or so.
But I am just getting a feel before anything serious.
What is the field circled in yellow with the black dot for? I can’t paste anything there and no menu drops down.
As you can see I can edit other Properties without the dot such as at the far left.
thanks


Not sure the reason for black dot, maybe means drop down menu? I just added a game property, a property actuator with the mode set to toggle, and the property name shows up in a menu drop down. Maybe you don’t have any game properties added, for it to show up in the drop menu?

This.

The property actuator scans the object, and creates a drop down menu containing them.
if you don’t have any property on the object the drop down menu will be a dot, saying its empty.

Thanks, that makes total sense.

What will happen from 2.8 on?

i think they plan on using upbge? but 2.8 is still a ways out, and learning this version definately wont hurt. many of the concepts will carry over, along with general game making experience for other engines.

i personally will probably stick with 2.74 until the 2.8 bugs are smoothed out.
