Just to make things clear:

A timer can't continue to count down when the program is closed. A closed program does no calculations, so actually while closed nothing can be changed.

But on startup you can compare the timer with the system time and see how much time has passed. You would then have to make events to change everything that would have changed in the time past.

The plugin gets the time from your system. you should be able to get that on start of your first layout so after that the program takes over the time.

If you put the time into a variable and save it when closing the program on restart you could compare the saved time with the system time on startup and discover how much time has past.

That is what system time means, the plugin I linked to gets the time from the system it is on (be it phone, tablet, pc).

So this should get you running in the right direction.

What time it is where?

If you want to know the system time you could try using the system time and date plugin

Did you follow these steps?

Layer or layout?

For second layout it would be as simple as

system go to layout

For a layer it could be more difficult, because you'd have to make sure the events for that layer aren't active when the other layers are and only set them to active at the right time. This would probably mean working with groups and/or is layer visible conditions.

I've been very busy working on my own project.

Did make some attempts but wasn't working as well as I'd hoped.

have an idea to fake it though, but will take some tweaking to get the feel..

NaN means not a number.

Webstorage is saved as a string.

You are forgetting to convert the string into an integer.

if you put int() around the webstorage like in the above example by anata, you convert the string into an integer.

Choose new project, scroll down untill you find infinate jumper, and click to open the example.

You should check if the webstorage key exists before setting ismuted.

add a subevent to the on start of layout and set it to

Local key exists "ismuted" - and add the events to set from webstorage as actions to that event.

you can't set ismuted to a value that doesn't exist.

example

I used:

platform is overlapping gravzone - platform set angle of gravity : gravzone.angle

and rotated the gravzone so it's angle was in the direction I wanted the gravity to go.

It still has some issues, primarily in switching between gravityzones, but It should be possible with lerp.
