MMF2 Power-up Problem, Please help if you have the ability to.

Hello everyone, I haven't really told anyone about this, but I'm making my own Mario fangame (and my first). The problem I have right now is that when Mario touches a power-up, two of him is created!

Example:

Event
"Small Mario" collides with "Mushroom".

Action
Destroy "Small Mario"
Create "Big Mario" at (x,y) relative to "Small Mario"

Then when I run the application and take the power-up(Mushroom) I sometimes get 2 Marios into the playfield at the same time. I've desperately tried to add Events like "run this event once" etc. but nothing seems to work. Therefore I am asking you guys for guidance....
Have you encountered this problem yourself before, and do you know how to fix it?
Is there some way to make an event or something that says something like "Only 1 object ofthis type is allowed in the frame, and if more delete the extra ones."?
PS: If you didn't read the title I'm using MMF2.

try switching the actions around so they go:

Create "Big Mario" at (x,y) relative to "Small Mario"
Destroy "Small Mario"

basically you're trying to reference an object that you just told MMF to destroy, which sometimes cancels the Destroy action

NObjects("Whatever") > 1
+ Pick one of "Whatever"
--> Whatever - Destroy

The small Mario is not a problem, it gets destroyed.
The problem is that when Small Mario is destroyed and the power-up, instead of 1 Big Mario, there are 2 Big Mario's really close to each other.

But the code that you wrote might help me with this. But i'll have to wait until tomorrow to find out, since MMF and the game is saved on another computer that won't be available until tomorrow.

you might not have a Start of Frame destroy action for the Marios you don't need at the time

I do have that.

What I suspect is that the power-up is there for just enough time for it to be created 2 Mario's before it is destroyed.

it could be as simple as the newly-created retriggering the event somehow

try making it destroy the mushroom before it creates the new Mario if you aren't doing that already

actually, it's possible this could happen since MMF doesn't destroy objects until the loop AFTER they've been told to be destroyed

destroying the powerup before Mario is created should destroy it before the event has a chance to be triggered a second time

Do you mean putting in a code like

When "SMall Mario" is destroyed

---> Create "Big Mario"

?

The problem with that code is that the problem would get worse Since then ther ewould be new Big Mario's coming all the time.

no

"Small Mario" collides with "Mushroom"
--> Mushroom - Destroy
--> Create "Big Mario" at (x,y) relative to "Small Mario"
--> Small Mario - Destroy
