Using the same key to toggle a state.

Hello all,

Im trying to get my each around this event based programming and I can't seem to solve this problem of using the same keyboard button to toggle a state on or off.

Attached is my implementation:

http://dl.dropbox.com/u/5760424/lol.capx

What it is suppose to do:

When the black square moves (using the w,a,s,d keys) to a grey square and presses the space button (while facing the square) a message pops up and the black sprite is frozen until the interaction message is terminated with the space button again. However I am unable to terminate the interaction message with the space button and I am temporary using the control button to terminate the interaction message. This is because the space triggers both popup and termination of the message at the same time. This is where I need help. If you don't get what I mean please download the file from the dropbox link.

Use the boolean instance variable that you've already set up for the player: 'interact1'

keyboard 'space' - toggle boolean 'interact1'

• player boolean 'interact1' true? - do stuff
• player boolean 'interact1' false? - do other stuff

or something like that.

Although, I haven't gone through your example very closely... as long as you only toggle it once per tick, you shouldn't have any problems.

edit: Here you go.

Toggle? Simple:

+ On some key pressed

• somevariable = 1 - variable

Thanks, I'm so blind I completely missed the 'toggle' action. This is exactly what I was looking for.
