Perhaps if:

1) You separate all continents and move them around appropriately

2) Make all continents a single family and scroll the family around, resetting it's position when ever needed.

3) The whole thing should exist on a layer set to opaque, with a Sea-blue color and the sphere effect added to the layer..

?

You need to add the "Play (by name)" action and on the "Name" field type either "S & round(random(5))" or choose("S1", "S2", "S3", "S4", "S5") and give it a tag name

Don't forget to add the "On Ended" condition and add the tag name you just gave.

Sorry, I have no idea

Can you share the capx or the image in question?

You can also use the abs expression to always get a positive value.

e.g. abs(-127) = 127

There you go. You can always find the latest release here.

For some reason the physics behavior ignores the sine behavior movements. If you script the movements then the box moves along the platform, but not quite at the same speed. If you use a pin behavior then the box sticks to the platform but other problems rise. Here is an example capx to display some of the above.

What you basically need is a way to trigger actions upon specified timed cues. You can use the "system---> compare 2 values" and pick the playback time.

The thing is that C2 or HTML5 sound isn't reliable when it comes to timing or synchronizing audio. Take a look on the attached example. While I use a "All preloads complete" condition to trigger the music, it takes half a second for it to actually start. That's making syncing a tedious an unreliable task.

Of course, you have to figure out a different system to trigger actions than the one I have on the example, because otherwise you will lost count after just a few seconds/events...

Perhaps adding a shortcut to the Startup folder (on Windows)?

You are welcome

It was a bit of trial and error, but I had confidence that somehow it should work since blackhornet suggested this way.

Anyway, you are welcome!

Oh ok, I missed that part. You need a global variable (e.g. FallingSpeed) to control the speed of the falling stuff and you increase it as the score gets higher.

I took the liberty to add an invisible "Bucket" sprite to collect the fruits and made the player take damage if the rocks fall on his head instead of the bucket. Also I added a flashing 2second invisibility when he gets hit. Finally, now there are 2 hearts on the top right that reflect the player's remaining life. These are but a few of many-many things you can do. Keep what ever you feel it fit's your needs.
