use an array and make it global to the game.

you just need to store the data in a way that the game will remember across frames. If you have global values to spare you can easily use them like flags. (0 or 1)

So when you don't have a particular gun, the global value it's related to is 0 and when you do the global value is 1 (even better if you can collect multiple you can still use just the one global value)

so say you want to code it so

Pistol = Global value A (0 or 1 have or don't have)
uzi = Global value B (0 or 1 have of don't have)
grenade = Global value C (0 up to 99)

then when you go to your gun collection frame make events to check what the current global values are set to. Then if they aren't 0 display the gun. and put a counter next to the ones that can have more than 1.

easy!

well i dont know how to use arrays...
you missunderstood me, though what you said was helpful for something else, but i just want it to display that youve picked up that weapon before, that its been discovered, like in the megaman battle network games your library of chips, or in sonic unleashed how you pick up secret documents and pictures and what not

Neatos! I Didn't think about using the array object for that!(probably because I've never tried it. ) I'll have to try that sometime. Thanks for the advice I never even asked for!

What AndyUK had previously said was exactly the answer to the question you asked. You want your game to remember that you've picked up a gun and show it on a separate frame; Global Values are the most simplest and easiest way to do so. If you didn't understand him;

If you have the gun, set a global value to 1.

If you are on that extra frame, and global value = 1, display information about that gun you have discovered.

If you are trying to do this for, say above 10 or more objects (where you don't have enough global values to use separately for each one), then you will probably want to use a save/load system where you can externally keep the data that will tell your game what you have and have not discovered.

There's an extension called Global Store X aswell. It's very handy as it stores values and strings globally and can save the data to INI or binary files.

they all work. an array is not the simplest but its probably the most efficient and flexible. it allows for not just that you have the gun but you can also store how much ammo and any other info you may need to store across frames. and yes you can save it externally as well.

The only problem is that just telling him to use an array isn't very helpful. You need to show him step by step.

Go check the articles. They might have a tutorial for array objects. If not, someone really should make one. It would solve some good number of problems and answer a large number of queries. I can't make one because I tried it. I'm braindead when it comes to array objects.
