okay, so the area I am trying to spawn in has an x range of 71 to 744, so each object (when it spawns), will need to spawn inside that area, and not the rest of the viewable screen (which has a layout size of 854, 480. So if I understand you correctly, it should look like:

x=random(71,744) since that is the area I want it to spawn within, or x=random(71, 854 - 110) ?

Is that correct?

The object will be onscreen until another icon is clicked, at which point it will destroy and spawn another random object, up to 10 times. I have everything else down, except for the spawning randomly and the random placement of the spawning. The items will be stationary once spawned.

These objects are spawning in different places, so I'm not certain that will work...

I do have the personal license, it just doesn't show up on Scirra because I bought it through Steam. I tried the formula, but no matter how I enter it it keeps telling me something is wrong. Mostly it doesn't like the "," in the middle of the x formula...

I tried it exactly as shown above.

I have 7 notes, and I only want one to show up on the screen at a time. I think I can do that using a family, but it won't let me enter the formula. Also, how would I make a family - spawner that spawned the different notes at different y-coordinates? I think the formula would be a little different for that, right?

I have seven objects I want to spawn randomly, but I only want one object at a time to be on the screen. Anyone know how to do that?

I am making a music bar, and I want to set notes to randomly span different positions on the bar, but I want the note to stay in the correct place. I have set the correct y position, but I want it to be able to spawn anywhere between the beginning of the bar and the end (on the x scale), but not anywhere else on the view-able screen. Any ideas?

Awesome, I was looking for that plugin download link everywhere! Glad I thought to look at the end of the comments.

Okay great, thanks. It seems to be working now, although I'm not certain why the code did not work before and now does...without any changes.

I tried to post my screen shot, but it is not working....I also tried to post my screen shot from dropbox, got a message that I am not allowed to post urls? not sure how to get the screen shot posted...

So I am trying to follow the make a platform game tutorial, but for some reason my "set mirrored" to turn the enemy left when hitting the first invisible wall is not working. I have triple-checked what the event sheet says, and it looks correct. Currently for the enemy I have:

Enemy action = "right"-> enemy simulate platform pressing right

sub action: enemy set Not mirrored

Enemy action="left" -> enemy simulate platform pressing left

sub action: enemy set mirrored

Enemy on collision with Edgemarker->

sub event: action="right" -> enemy set action "left"

sub event: else -> enemy set action "right"

Is there something I missed here to make the turning actually works?
