How do I make a button that turns on when pressed then off when pressed again?

DinoBit

I am pretty new to this kind of stuff. I know how to make a normal button, but how do I make a button that turns on when pressed then off when pressed again?

You will need to have 2 different images, so you can say when you put it in a rule

when touch is pressed
do
change image to ( whatever is your turned on image)
else
change image to (the one that was already displaying when it was not pressed)

I think you misunderstand my question. I'd like it to turn on a bolean attribute when pressed, then turn off a bolean attribute when pressed again. how do i do that?

You can use a boolean but it works much better to use an integer with possible values of 0 (false) and 1 (true).

With a boolean, there can be a problem with the rule running in a loop (if touch is pressed and true, change to false; if touch is pressed and false, change to true; BUT uh oh, when it changes to false and I'm still touching the actor, it then changes immediately to true... argh!)

When touch is pressed
     Change attribute game.anInteger to 1-game.anInteger

So if game.anInteger is 0, it will change to 1. If game.anInteger is 1, it will change to 0.

thank you so much!

@Tatiang - Holy moly... I've been using GameSalad for 3 years almost all my apps have buttons that go on/off with a single tap... I never, ever came up with your simple idea of avoiding the loop problem (usually fiddled with timers!)...

Thank you!

So neat, @tatiang, I really like that too! :-)

For the record, for new users, the loop method is watertight providing it's done properly using the Otherwise section (although not as elegant as your solution, @tatiang ! )

Rule:When touch is pressed
Rule ---nested--:When BoolLoop is false
Change Attribute BoolLoop to true
--do your thing
Otherwise
Change Attribute BoolLoop to false
--do your other thing

@TomCoffee Any type of loop is only "fiddled" with timers if you want a pause before the next loop iteration; or to to give a time limit to the loop, for instance – both valid uses of timers.

Good to know @gyroscope... somehow I missed that.

And I can't take credit for the subtraction method. I always see @Socks post it. B-)
