Although I don't know any Russian, I would be more than happy to try to make your translation or google's translation understandable once you release it.

Aha! Delta time is what I would be interested in as well, somehow I managed to skip right on past demo 01 which shows the basic setup.

Anyone interested?

Lazarus is nice, but overkill for developing ZGL apps. I started working on a little ZGL IDE a while ago. Of course it has a long way to go before an alpha release (it barely functions!), but I think I'll GPL the source and post on these forums once I feel it's stable and usable enough.
