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!

CommandWarp.java

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.

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.

      REVIEW OF THE BEST BITCOIN RECOVERY TEAM - MUYERN TRUST HACKER

      By andreygagloev · Posted

      When I first heard about Bitcoin back in 2018, I was skeptical. The idea of a decentralized, digital currency seemed too good to be true. But I was intrigued as I learned more about the technology behind it and its potential. I started small, investing just a few hundred dollars, dipping my toes into the cryptocurrency waters. At first, it was exhilarating to watch the value of my investment grow exponentially. I felt like I was part of the future, an early adopter of this revolutionary new asset. But that euphoria was short-lived. One day, I logged into my digital wallet only to find it empty - my Bitcoin had vanished without a trace. It turned out that the online exchange I had trusted had been hacked, and my funds were stolen. I was devastated, both financially and emotionally. All the potential I had seen in Bitcoin was tainted by the harsh reality that with decentralization came a lack of regulation and oversight. My hard-earned money was gone, lost to the ether of the digital world. This experience taught me a painful lesson about the price of trust in the uncharted territory of cryptocurrency. While the technology holds incredible promise, the risks can be catastrophic if you don't approach it with extreme caution. My Bitcoin investment gamble had failed, and I was left to pick up the pieces, wiser but poorer for having placed my faith in the wrong hands. My sincere appreciation goes to MUYERN TRUST HACKER. You are my hero in recovering my lost funds. Send a direct m a i l ( muyerntrusted ( @ ) mail-me ( . )c o m ) or message on whats app : + 1 ( 4-4-0 ) ( 3 -3 -5 ) ( 0-2-0-5 )

      corail tombstone fire crash

      You could try posting a log (if there is no log at all, it may be the launcher you are using, the FAQ may have info on how to enable the log) as described in the FAQ, however this will probably need to be reported to/remedied by the mod author.

      corail tombstone fire crash

      By belzabel · Posted

      So me and a couple of friends are playing with a shitpost mod pack and one of the mods in the pack is corail tombstone and for some reason there is a problem with it, where on death to fire the player will get kicked out of the server and the tombstone will not spawn basically deleting an entire inventory, it doesn't matter what type of fire it is, whether it's from vanilla fire/lava, or from modded fire like ice&fire/lycanites and it's common enough to where everyone on the server has experienced at least once or twice and it doesn't give any crash log. a solution to this would be much appreciated thank you!
