kalakala If I'm understanding, you're wanting to have random items spawn? You could do a "System > Every X seconds" with however many you want, or random, and then in that do a "System > Create object" with the x as random( smallest x, biggest x) and the same for y. Just make sure you check what range you'd like the items to appear in and put that in the parenthesis after random. Does that make sense?
Since you probably want it to always appear in front of your player, maybe you could do "player.X + random(10,100)" or something similar.
