How do I Create Random Sprite size layout

Hello everyone.

I have a layout size: 1500,700, and this event:

[attachment=0:11xwe935][/attachment:11xwe935]

it works, but i would like that the creation of the object was only between 100 and 600 on Y axis, and not the total size o Y axis.

How can i do that?

By using the wonderful random(A,B) function, thus random(100,600)

Or, if you are allowing resize, random(LayoutHeight * x%, LayoutHeight * y%), where x% and y% are the minimum and maximum %of the height they should appear.

For example:

In a 480 x 640 layout if you'd like to have they appear between 100 and 600, you should use random(LayoutHeight * 0.16, LayoutHeight * 0.94), so, if the layout resizes to double its original size (960x1280), instead of having sprites appearing only in the upper half of the screen (100-600) they'd still be distributed proportionally as you expected (200-1200)...
