[1.12] (Solved) My List won't save after I exit the world and rejoin

Hey all, I'm new to modding and just ran across a problem with the mod I'm making. 

I want to have a list of warp points that the player has created so that the player can go around the world faster (it's just tedious running out to my mob spawner 1000 blocks away from my base and running back again after I'm done). So I created a command called warp that allows the player to set warp points to places he has already visited so he can just quickly teleport back and forth whenever he wants. My problem is that whenever I enter my world, my list of warp points isn't saved from my previous session. I figured this is probably because my mod is being reinitialized every time I join the world again, but I don't know how to fix that. Any help is greatly appreciated, thanks!

    If you do not know much Java then I suggest you learn before continuing, and if you do this could be really easy. You have to save the contents of your List to the Drive of your computer. Whether this is in a text file or an NBT file. You will want to use the WorldSavedData along with some events to read and write the data.

    VANILLA MINECRAFT CLASSES ARE THE BEST RESOURCES WHEN MODDING

    I will be posting 1.15.2 modding tutorials on this channel. If you want to be notified of it do the normal YouTube stuff like subscribing, ect.

    Forge and vanilla BlockState generator.

    Isn't WorldSavedData deprecated because of capabilities ?

    Thanks for replying so fast! I completely forgot about using a text file, so I'm going to try that first. I'll also check you the WorldSavedData and read up on the Capabilities too, Thanks!!

    No, World Capabilities are implemented as a wrapper around World Saved Data but are nicer to work with.

    Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.
