make an object never appear again

[Scissors]

I just would like to know if there's a way for the player to get an item an make it never appear again in the game

What determines that the player has the item? Check for that before creating the item.

Sorry but I don't understand completely what you mean, isn't there a variable that just makes it never appear? I'm kind of a beginner tho

 

[CloseRange]

what do you mean by "never appear again"?
i'm going on a limb and assume you mean that you want the object to just go away?

instance_destroy();

this will destroy the object that it's called in.
however if anywhere else you say to create another one of those objects then it wills till be made.
in that sense the object WILL appear again but only if you say to create a new on.

Create a list of all objects and shuffle it with ds_list_shuffle. When you create a new object, just get the first item in the list and delete it

You can't make it NEVER APPEAR IN THE GAME AGAIN unless you never create the object in the game.
Also as @CloseRange said,you can destroy the object with the piece of code he wrote.

Yes, I knew that. What I mean is if for example there's a level with a certain item you can get once but if you enter the level again it won't appear never again

just store the state of the item in a variable.

global.SwordAlreadyPickedUp = true/false;
objInventoryManager.SwordAlreadyPickedUp = true/false

Then in your room start code, or the create event of some room controller object, check that variable and delete or add the item as necessary

I know a guy who knows a guy that can make that happen

I would store a small text file or simple data file storing whether that item has been picked up or not, then at the start of the room or level make the item check the file

No, and you just solved your problem. Create this variable. Then save it to a file. Before you call for the object's creation, verify this variable, and don't create it.

Create a list of all objects and shuffle it with ds_list_shuffle. When you create a new object, just get the first item in the list and delete it

Not only this is not related to the problem, but you also inject a new one: Controlling the existence of all the items in the entire game at the same time.
Both problems are solved the same way: Save the game.
By the way, though this is a very bad system, it's as close as one can get to unhackable. I use a system like this in my project, and basically if a hacker hacks a weapon into a room, by leaving the room it disappears because it was not acquired. xD

You can't make it NEVER APPEAR IN THE GAME AGAIN unless you never create the object in the game.

Wrong, you can create an object only once. Just like you can get to any event only once.

Yes You could create it once and never create it again.
