Use a string variable named chainStep, default it to an empty string (“”).
If button A is pressed and chainStep = “”, set it to “A Pressed”
If button B is pressed
→ subevent chainStep is not “A pressed”, then set chainStep to “”
→ subevent chainStep is “A Pressed”, set it to “B Pressed” (or play sound)

EDIT: MrMen’s answer is much better & simpler!
Hey @masterh1! This is super simple to do! All you need to do is make it so when you click A, it changes a variable from false to true. Then, when you click B, it checks if the variable is true, and if it is, then plays the sound!
If you don’t want it to be able to happen more then once, then add another variable to “lock it” like this…
There might be a simpler way to do it, but this is the simplest way I could think of! Hope this helps!

this worked so far
i click A then B and the sound plays
but when i click A then C and then B it still plays
that was not intended. i want to setup a riddle
whre you have to click the buttons in an exact order.
couldnt figure out the other method. pictures help alot
Currently, the set up I gave you was “When you press A, Unlock B.” That’s why when you press A, then C, B is still unlocked. Here is what I think is the best way to fix this.
Since you have multiple buttons, (at least 3), the best way to do it is to assign each button a variable, and then check variables.
But wait a second! That means you can click them in any order! You could click CBA or BCA and get the same result! I decided to think about it a different way and combined my knowledge with @MrMen’s and came up with this:
This way, every time a button is pressed it gets added to a variable! So if you press A, then A, then B the variable says “AAB”! This method does require a reset button but can work with any number of buttons!
Hopefully this helped and thanks so much @MrMen for letting me borrow some of your knowledge
Edit: For context, Pressed is a Text Variable that starts with the Value of “” which is nothing, that when when buttons are pressed it adds that button’s value to the variable.

[edit]
If you want to be able to have the button press in different sequences, then @SnowyRawrGamer’s second solution (of storing the keys in a string and a reset button) will be a better solution.

Hi all!
In classic programmation, i would use the concatenation of variable then i would sort up this variable (NB: here too with GD, you can use it)
So, regardless of value of the variable (CBA, ABC, etc. or even DBAC, BADC, etc.)
you should get ABC or ABCD.
After, it’s easy to test:
if variable = A then …
if variable = B then …
…
if variable = ABCD then …
The boolean variables are useful for binary decision.

i have sprites that act like a button
and i want to build a sequence on that.
i cant find a condition like blinkerl was just clicked 
i dont understand why you change the background colour
“Is clicked” is that action. I believe it is true once during the frame when the click and release happens for a button click.
Ah, that was an action I should have removed. It’s part of my testing and is a simple way to confirm an event is actioned.
