mc plugin hardcore grace period

[pearl dune]

I am really new to java and I am trying to code a spigot 1.21.8 plugin but I need this done before friday for a minecraft server for my friends.

This is how the plugin works: The world is on hardcore. When a player first joins the world, they will have a 1 hour grace period where they can respawn. If a player leaves during their grace period the timer keeps on running. And after one hour, they player is now fully in hardcore mode and if they die, they are dead.
As you see this is per player meaning it's local. So I want it that every player gets a 1 hour grace period at their FIRST join.
(CODE IS IN THE CHAT, NEEDS HELP!)

I recommend starting with some basic tutorials on Java programming and Spigot plugin development to get a better understanding of the process. Since you are on a tight deadline, it would be helpful to focus on simple functionalities for your plugin. Here are 3 useful links to guide you in coding your Spigot plugin:

in my opinion, you should try chatgpt for quicker plugin code or grok for heavier logic in your plugin. If it doesn't help, then get back here

[pearl dune]

The code is sadly made with chatgpt. I had to use 3 different google accounts before I gave up on chatgpt 😭

[magic karma]

use grok instead

[pearl dune]

Alright, thanks a lot.

[magic karma]

he's a bit smarter

just give him good response

[haughty tartan]

this code is literally useless

[pearl dune]

how so?

[haughty tartan]

the grace period starts at the beginning of the plugins lifecycle

and loops through all online players... ... while nobody is online

[pearl dune]

Can you take a look for me please? I truly need help

[pearl dune]

ohhhh

[haughty tartan]

youre welcome

[pearl dune]

how long do you think it's gonna take u to create this plugin? Just asking (help is always needed)

[haughty tartan]

not very long

as soon as the player dies and their grace period is over... you just ban them

[pearl dune]

Or do you know if this plugin already exists? 🙏 I did at least 12 hours of research

[haughty tartan]

I've not looked

[pearl dune]

Ohh well I am very new to java lol. I know absolutely nothing

[haughty tartan]

https://www.spigotmc.org/resources/hardcore-lives-plugin.79254/

[pearl dune]

I just really want this plugin so me and my friends can play

[haughty tartan]

look at this

[pearl dune]

Players will have lives which means that they can respawn a custom set amount of times, not a grace period. We really need a plugin that gives a grace period of 1 hour, not lives.

Thanks a lot tho

For helping me, it truly means a lot

But idk man, there's just nothing I can find

[haughty tartan]

take a little longer to understand what the plugin does

bceause that is not it

[pearl dune]

oh huh... what do you mean?

[haughty tartan]

look at the commands & config

[pearl dune]

yea but it only gives a certain amount of lives. Not a time period

[haughty tartan]

yeah, so you just disable it when you decide grace is over

its based on their no. of lifes

[pearl dune]

But we have like 80 players 😭 and everyone joins a different time

[haughty tartan]

then yeah, you will have to make your own

[pearl dune]

ye great

[dull folio]

hardcore isn't a game mode

you'd have to mess with both the respawn mechanic and the packet that the server sends to the client saying that the game is in hardcore mode
