Assuming 'Platform' is the name of your platform object, the last one should be Platform(Platform.count - 1). You can pick it this way, and make it spawn at an offset. If you use a tilemap, i have to think some longer. Its very handy if you make a .Cap with the basics covering your question, so someone can alter it for you.

i triyed with platform count but don't work, the object spawn in other position...

(I don't post capx file because the forum don't authorise me)
