Changing 99 of normal item into 1 golden item

[FemaleMarauder7]

Throughout my game, the player has a chance to find 99 Keys. By doing so they are able to unlock a "bonus room" that will basically be an in-depth credit scene (instead of scrolling text it's a room where they can interact with all the assets and read who made them). My goal is to automatically change the 99 Keys into a Golden Key once the player is transferred into a room after beating the final boss. I'm having trouble making this work.
I'm using a control variable for it to check for the 99 Keys and a conditional branch if the player doesn't have it. The event is giving me the Golden Key regardless if I have the 99 Keys or none.
Maybe I'm just not understanding how variables work? Or is there an easier way to do this?

This is how my event is currently set up:

You are setting the variable to 99, so it will always work. What you want to do is each time you find a key, have the variable add 1. In this event you should not be setting the variable.

For testing purpose, you can set the variable to a random value, I'd do probably 97-99, so it sometimes has a chance of working.

I would do it differently, but it's harder for testing purposes, I guess. You can make it in a way the variable will store the amount of an item you have. I'd do this and then check if it's = 99. (I used Beer and Map because that's what I had lol)

This is my first game so I didn't even know that was an option.
It fixed my problem. Thank you so much!

I found your problem.
I ran it on my RPG Maker and it worked perfectly. Check this out.
Cat gives me 97 Regular Keys
my inventory has 97 keys now No GoldKey
Mr Dog gives me 1 Regular Key
my inventory has 98 keys now No GoldKey
Mr Dog gives me another Regular Key
my inventory has now 1 GoldKey, no Regular keys.
Mr Chicken is the control parallel process, it should be invisible but I just left it there to see how it behaves. The moment 99 keys are substracted and 1 goldkey is given to me, The Chicken transforms into the Dark Knight to show me that I have successfully broken the conditional loop into an empty event.

You were forgetting to substract from the variable -99 keys so it stops activating the conditional. Substracting 99 keys is not enough, you must also substract 99 from the "keys" variable and set the self switch of the parallel process inside the conditional

And here it is in action:


Please notice how Mr Chicken becomes a DarkKnight the moment MrDog gives me the final key and thus me obtaining the golden key and the conditional loop breaking forever
Hope I could help a little
