How can i do switcher from 1 to 2 and back by 1 button?

How can i do switcher from 1 to 2 and back by 1 button?

i do something like

-if button pressed and variable = 1 then make variable 2

-if button pressed and variable = 2 then make variable 1

but as i can see, these events work one after one, so i always have my variable = 1

of course, i can do it by 2 buttons, but i wanna with one, is it possible? pls help me

The second event needs "Else" added.

yea, thanks, i found guide on the forum about else in this situation, but it works properly only in suck case. but i have under one event subevents about whole group of my sprites, where each has to be switched from 1 to 2 anb back. by using "else" i cant realise it, but i also found that i can do it following way:

--if button pressed and variable = 1 then add 1 to variable

-if variable >1 then make it 0

Variable=1 and the else should be subevents of on button pressed and it should work.

You can also toggle the variable between 1 and 2 with one event:

On button pressed

--- set variable to 3-variable

Just be sure the variable starts as 1 or two.
