first key press after launching a game

Try this cap: http://tecbug.pl/pub/problem1.cap

Space should always change sprites animation.

But it doesn't do it on the first key press (space) (after launching a game). After first space press it works fine. What is wrong?

Since this is basically a toggle, you won't get get proper results with events like that. You should use an ELSE condition for this.

Or even easier:

Thanks to Shviller for pointing that one out, hehe. It's a nice and simple method for toggles.

Thanks for great advice!
