I have had this problem in MMF forever and my work-arounds are pretty lack-luster, so I thought I would ask the community. Here goes:
I want to use spacebar as the 'action' button. So, the character walks to a shop, presses 'spacebar' and a menu opens up. Then they look at it, and when finished, press 'spacebar' again to close the menu.
Here's the (apparently faulty) way I code it:
-----------------
'Hero' overlapping 'Shop' + User presses 'spacebar'
- Make menu objects visible
- Set Shop value A to 1.
- Pause 'Hero' Movement
If Shop Value A is 1 + User presses 'spacebar'
- Make menu objects invisible.
- Set Shop Value A to 0
- Un-pause 'Hero' movement
-----------------
When I do that, nothing appears at all. I am assuming that it counts the spacebar press in both events back to back, instead of running the first one and then leaving the second one alone until another spacebar press takes place.
Can anyone help? I've tried using a quick timer in between, but that is sloppy and doesn't work 100% of the time.
Thanks in advance!!!

I believe your code should work if you just swap the order of the two events, but I'm not sure.
If not, try using a flag, and just toggle it when user presses spacebar.

I think the flags should work. Thanks for the tip!

also.
setting a variable value of an active object on screen to contain a countdown number would help this.
for instance
-----CONDITION-------------------------------------------ACTION-----------------------------------------
-----------------------------------------Activeobject1(shop)------------menu-----------Player1----------
if hero on shop
+ space bar pressed
+ valueA(activeobject1)=0-----------set valueA to 3----------------reappear-------ignore-control--
+ menu is invisible
+ limit once per action
if valueA(activeobject1)>0----------subtract 1 from valueA-------------------------------------------
+ every 1 second
if hero on shop
+ space bar pressed
+ valueA(activeobject1)=0-----------set valueA to 3-------------make_invisible----restore-control--
+ menu is visible
+ limit once per action
this would stop the menu appearing and dissappearing so quick.

You can use toggle flags for those kind of stuff aswell.
press spacebar - toggle flag 0
flag 0 on?
open shop, pause movement
flag 0 off?
close shop, continue movement
and you can limit to only one action per event. So it doesnt repeat actions if the flag doesnt change.
Ah, i m getting blind, just noticed sketchy already pointed toggling flags.

I think by just toggling flags u can turn them off and on in one press
because the events occur in order unless something is different to the previous line
for instance
---------------------------
if key pressed
+(object) is invisible-
then
set (object)flag(0) on
set (object) visible
followed by
if key pressed
+ (object) is visible-
then
set (object)flag(0) off
set (object) invisible
--------------------------------------------
the first bit turns it on and straight away the next line would turn it back off,
doesnt matter which way round u do it unless you change a value of something on each line.
whereas
-----------------------------
if key pressed
+ (object) is invisible-
+ value A(object)=0
then
set (object)flag(0) on
set (object) visible
set value A(object) to 1
followed by
if key pressed
+ (object) is visible-
+ value A(object)=0
then
set (object)flag(0) off
set (object) invisible
set value A(object) to 1
followed by
If value A(object)>0
then
set value A to 0
-----------------------------------
because the valueA(object) was changed in the first instance the next line would be false cos a=1 so the programme would skip this event. then The last line sets A back to normal
you could even use another flag
whereas
clearer?

You can't turn them off and on in one press when toggling.
because action is not
set flag 0 on
its
toggle flag 0
