Seamless auto scroll and looping (clouds)

[darkmanx_429]

Can someone explain to me how I would go about coding a seamless auto scroll? In my example, I would like to assign my active object (an image of clouds) to a background layer and have them scroll and loop in the background. It is merely for an effect purpose.

What I have been doing is giving a pinball movement to the active object in the direction I want it to go in and then making a 2nd active object that is a duplicate of the first also giving it the same movement pattern.

I then just add an always function to create endless duplicates that meet at the action point of the first object. I then assign another timer condition to destroy the duplicates after a set number of seconds to avoid endless duplications. I added a fade to the 2nd duplicate upon destroy so it looks seamless.

Just curious is there an alternate way to have seamless auto scroll?

Active picture if you don't need collision detection. Although, people have said Collision detection works with this. I have yet to see it or get it to work properly with a transparency. For me, the ACTIVE picture just acts as a whole so making sun flares and such, just never work.

X Offset of( "Active Picture" ) + 1

Now if you want what I use that allows for Collision Detection and allows you to make sun flares. I make two identical Actives called Clouds ( COPY the first ). Then set them both in the same direction and when one meets a certain -x Value. Reposition it to outside on the right ( Clouds moving left ). I use an always event and set it like this.

X Position of( "Clouds" ) - 1

So basically the clouds you see are always on the frame viewing area but swap over and over.

Both ways work for making Daytime and Night Time cycles too.

This video shows both of the ways I described.
