I have a game with two main states: with a menu open and with it closed. I
switch between these two states by popping one set of handlers and pushing
the other (and turning a visible flag on and off on the menu elements, and
unscheduling or scheduling my update functions). However, I've found that
when I pop the handlers the following happens:
- scheduled updates don't occur
- event handlers don't trigger, including on_draw (custom mouse cursor is
frozen in one place, animations are frozen)
This continues until I press a key or click the mouse. Using win.activate
does nothing. I attached a toy script the demonstrates the problem.
Thanks for any help!
