Dump noob timer question

[oswald]

I know, this might be a dump question... but checking the tutorials and some demos did not really brighten me up.
How can I have objects appear at random x-positions on the top of the screen. While the amount of objects and object-speed increases the more time is going by...

VERY Rough and DIRTY
Put an invisible actor that holds a code that looks something like this :
On Draw actor > Create Timer A
On Timer A > Create actor (yourActor)
And finally on yourActor, put something like this :
On Create actor > Script >

x = rand(xscreen) ;
y = rand(yscreen)

Not sure of the vocabulary
