How To do toggle.

I'm making a game where i need to toggle a value, when player presses space bar value changes to 0 and when he again presses the value the value changes to 1, how to implement that please help!!!

Event 1:

Spacebar pressed - add 1 to value

Event 2:

Value higher than 1 - set value to zero

[QUOTE=Mipey] Easiest way would be:
variable = 1 - variable

With variable being either 0 or 1, it will always toggle (1 - 0 = 1, 1 - 1 = 0)[/QUOTE]

can you make me a small example file for it?
