Handling reloads

so I noticed array lists don’t save on reloads/restarts.

What’s the best way of saving these lists And retrieving?

If I save the list to a config and get it back on the onEnable, does my list automatically add the players from the config list back into the array?

I see, google searches haven’t helped me much for what I’m exactly trying to understand.

So if the onDisable loops all players inside of array and saves it, should it be deleted after it reloads to free up memory?

And secondly with adding the array back to each player will I need to get each player uuid from the list and assign it back accordingly? If so, would a for each loop work?

Thanks @timtower, with the static and non static modifiers, I’m unsure how this would be used in the config list, if I put all the players in the list into the config and save it, then how will it be deleted after I’ve grabbed the list back in the onEnable?

sorry if this sounds confusing, my theory is there will always (most likely) be a player that contains this list as it’s a spawn protection list, so stacking up multiple uuids is not what I want, after the players get grabbed from the list after reload, how do I clear it for the next onDisable?

Public void onDisable() {

For (Player pl : Bukit.getOnlinePlayers()) {

If (util.myarray.contains(pl.UUID){

This.getConfig.set(“templist”, pl.UUID);

}
}

Sorry for the rough copy I’m not with my laptop, is this the right way to go?

Sorry for the mess, I ended up finding a YouTube video showing me exactly what I was looking for. Although since this is a array holding all protected players, I need to also save the cube location (spawn cube).. when I reload my server I stay in my array but as soon as I move it doesn’t detect my cube and instantly removes me due to my Boolean check method. Is there a way of saving a list of blocks being my cube and get it back on reload?

But it’s a Location and I put it into a location array but I am stuck with setting/getting the location object into a config

It’s a Cuboid location too I’m im more confused

@timtower

Code:

public ArrayList<String> cubelist = new ArrayList<String>();

//util class list

Code:

public class Cube {
public Main pl;
public Cube(Main ins) {
pl = ins;
}

World world;
double minx;
double maxx;
double miny;
double maxy;
double minz;
double maxz;

 public void setCube(Location loc, int size) {
 world = loc.getWorld();
 this.minx = loc.getBlockX() - 5;
 this.maxx = loc.getBlockX() + 5;
 this.miny = loc.getBlockY() - 1;
 this.maxy = loc.getBlockY() + 5;
 this.minz = loc.getBlockZ() - 5;
 this.maxz = loc.getBlockZ() + 5;

 for (double x = minx; x <= maxx; x++) {
 for (double y = miny; y <= maxy; y++) {
 for (double z = minz; z <= maxz; z++) {

 Location area = new Location(world, x, y, z);
 
 String blockcoords = "world " + world.getName() + ".x " + x + ".y " + y + ".z " + z;
 
 if (y == miny) {
 area.getBlock().setType(Material.GLASS);
 
 }
 
 pl.util.cubelist.add(blockcoords);
 pl.getConfig().set("cubeloc.coords", blockcoords);
 pl.saveConfig();
 }
 }
 }
 return;
 }
return;
}

Main class:

Code:

public void onEnable() {
util.registerCommands();
util.registerListeners();
this.getConfig().options().copyDefaults(true);
this.saveConfig();

for (String arealoc : this.getConfig().getStringList("cubeloc.coords")) {

util.cubelist.add(arealoc);

}

@timtower ive realised something in my cube class todo with my varibles. the Boolean check doesn't know where the min and maxs are after a reload, im guessing.
so how would I reconstruct this if im going on the right path

Code:

public boolean isInSpawn(Player p) {
Location loc = p.getLocation();

if (loc.getBlockX() >= minx && loc.getBlockX() <= maxx &&
loc.getBlockY() >= miny && loc.getBlockY() <= maxy &&
loc.getBlockZ() >= minz && loc.getBlockZ() <= maxz) {
return true;
}

//MY CLASS VARIABLES
World world;
double minx;
double maxx;
double miny;
double maxy;
double minz;
double maxz;

So, where do I grab the min/max from?

 

@timtower sorry I don't understand

Bump
I know after I reload my server it doesn’t remember where my cuboid location is, and it’s because the min and max are unknown how do I fix this
