How do I have sprites repeatedly fly across screen?

Hi,

How may I achieve this effect.

I have a series of cloud graphics I have created that I need to randomly move across the viewport during play. I know I need to set them off screen to begin with and have them move in at random time intervals and ideally and variable heights each time.

Any advice on this would be great as its been bugging me for a while.

I don't know if I really understood what do you want, but you could use the event "every X seconds" changing the seconds by round(random(the_range_that_you_want)) and include after a "create object" event to create your clouds randomly too (X: random(range), Y: (random(range)). I would like to suggest you to try to use the "sine" behaviour for the clouds movement to make it more natural.

Great idea, thanks again!
