Is it some KivEnt bug?

Are the examples up to date?

Is there any other way I can test my KivEnt installation is OK?

[Jacob Kovac]

KivEnt has largely been tested with Python2.7 and Python3.4. I have never personally ran it on 3.6, and especially not on Windows and 3.6. It is possible something has changed that has made some previously valid code no longer valid. The one error about division by 0 is very suprising.

I've found some people with the same problem

https://groups.google.com/forum/#!topic/kivent/dAqLPKm0UW8

I want participate in Pyweek and their rules require the latest libraries (not to develop, but it must run there).

I just sent an email just to see if it's allowed to use Python 2.7 or 3.4

Just for curiosity...

I read KivEnt performance is amazing (prolly the best performance) compared with other Python stuff, but was still less than Unity and Unreal Engine.

How does it compare to Godot, Game Maker and Construct 2? (I'm specially interested in KivEnt performance compared to Godot)
