I don't know that one, but let's try …
Basically your game engine should have a main loop something
like this:
update(dt)
draw(...) -- sets up the new screen but does not show it yet
eventhandler(...) -- check keyboard, mouse, joystick etc
render() -- finally show the screen
"update" gets told how much time has elapsed since the last
time it was called. It's in here that you can put code like:
delay=delay+dt
if delay > too_long then pass=false; delay=0
else pass=true
end
Then in "draw" you skip everything if "pass" is on.
In "eventhandler" you check for slowdown and set "too_long"
to something positive, or set "too_long" back to if the slowdown
is cancelled.
