True. I think it'd be more elegant to use a method that didn't require a dummy unit on the map, though:
- Always:
Wait X milliseconds; Set switch 1.
- Elapsed time is 2 game seconds; Switch 1 is set:
Display "You're on fastest speed!".
- Elapsed time is 2 game seconds; Switch 1 is cleared:
Display "You're not on fastest speed!"; End game.
X is determined by trial and error, and chosen such that trigger 2 fires on fastest speed, but not on any slower speed. It would be approximately 1333 milliseconds in this case, I think. If it's inconvenient to test the speed at the very beginning of the game, use a countdown timer instead of elapsed time.
