ah, so the idea behind mine is that it's super duper easy to add more items
no coding at all needed, using some nice placeholder systems

Same goes for our approach. Just something like
new CombatItemBuilder(ModelData.COPPER_SWORD)
.withStat(CombatStat.CRITICAL_STRIKE, CombatStatMod(Type.BASE, 3.25))
.withStat(CombatStat.MEELE_DAMAGE, CombatStatMod(Type.PERCENT_ADD, 25.5))
.withSkill(...)

Uhm... Not sure what you mean by that. But sure. If the items are not dynamic then you can just create an ItemStack that is used for
display purposes and simply tag the real ItemStack with a String. Then you have a Map<String, ItemStack> and simply send the mapped
ItemStack instead of the tagged one. But again: Only if you want this to be static.

Is it possible to tell that a player is in the middle of editing a book?

That's a huge bummer but not altogether surprising 😭
tall dragon
there is an event for when a book gets signed iirc, but im pretty sure you cannot tell if they are editing a book
eager sapphire
Yeah I first tried PlayerEditBookEvent but as you say, that only fires when they finish editing (signed or not)
tall dragon
actually
i might be kind of hacky, but what if you keep track of players with a book open
u can add them to a list on player interact
and remove them on PlayerEditBookEvent
though there might be some issues where the player can close the book without being removed from the list
probably by closing the game is 1
eager sapphire
not a bad idea- could also remove them if they change to a different item
eager sapphire
I think for now at least I will just prevent the menu if they are holding a book at all
tall dragon
thats alot simpler indeed.
i guess its not that annoying for players, just need to not hold a book
eager sapphire
yeah and I admit it's a little weird to open a gui for a player unprompted, I may need to just rethink the idea, it's basically a /tpa GUI, so player 1 chooses a player to TP to from a menu, player 2 gets a yes/no confirm menu pop-up
tall dragon
would you not be better off sending a clickable message?
idk what kind of server you run. but an unprompted gui could mess up gameplay too
for example someone is in the middle of a big jump xD
eager sapphire
heh yeah it's been ... kinda annoying tbh XD
clickable message is a good idea, the main idea is to avoid using chat and commands but there may not be a better way.

im afraid a clickable message is best ur gonna get without disturbing gameplay
and, still u can make it look pretty good

If its only an overworld pathfinding then you should probably use a height map of the entire world (will only be some megs)
For surrounding chunks you can still use normal pathfinding.
Doing a 2D pathfinding lets you find a path over thousands of blocks (pixels) in a ms

A hash is basically a one-way numerical representation of something

Player p = (Player) sender;
List<String> lore = new ArrayList<>();
ItemStack hand = p.getInventory().getItemInMainHand();
ItemMeta meta = hand.getItemMeta();
for (int i = 0; i < args.length; i++) {
lore.add(args[i]);
}
meta.setLore(lore);
hand.setItemMeta(meta);
let me get a pic of out put
tender shard
```java
Player p = (Player) sender;
List<String> lore = new ArrayList<>(...
okay so you want to append the command args to the currently held items lore?
young knoll
Like I said, String.join(“ “, args) should work
simple anvil
yes
young knoll
Returns a single string
tender shard
yes, as COll said:
simple anvil
Like I said, String.join(“ “, args) should work
im still lost by this
tender shard
do something like this:
String line = String.join(" ", args);
List<String> lore = new ArrayList<>();
lore.add(line);
meta.setLore(lore);
String.join(" ", args) turns all the arguments into one string
simple anvil
so i dont need a for loop
tender shard
correct
simple anvil
ok

You could simplify that with Arrays.asList

@simple anvil I have a tip for you. Create a new java project WITHOUT bukkit/spigot etc
then try out the basics like turning a String array into a simple string
then you don't have to start up a MC server everytime for basic stuff like this

Myes Cyber, crucial thing to learn (from what I can tell) is the difference between List<Something> and Something[]
tender shard
yeah if you come from python, then it's really important to understand that an array is totally different from a list
simple anvil
public class AddLore implements CommandExecutor {
@Override
public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
Player p = (Player) sender;
List<String> lore = new ArrayList<>();
ItemStack hand = p.getInventory().getItemInMainHand();
ItemMeta meta = hand.getItemMeta();
String line = String.join(" ", args);
lore.add(line);
meta.setLore(lore);
return true;
}
}
does nothing
tender shard
a list has convenient methods like .add(), .remove() etc, while an array is PRETTY STUPID. it can't do anything lol
simple anvil
so when do i use array
ivory sleet
Fast as fuck but ye sucks otherwise
tender shard
```java
public class AddLore implements CommandExecutor {
@Override

that will ALMOST work
Your current code has one problem: You forgot to tell your your "hand" item to apply the new item meta
tender shard
you will also have to use
hand.setItemMeta(meta);
at the end
otherwise you do change the meta's lore, but you don't apply it to the actual item
it works like this:
simple anvil
yea, i forgot about that
tender shard
ItemMeta meta = someItem.getItemMeta();
// change the meta now
someItem.setItemMeta(meta); // Apply it to the item
i forgot to add @EventHandler and spent 30 mins trying to get it to work
tender shard
oh yeah that happens to everyone sooner or later
simple anvil
```java
ItemMeta meta = someItem.getItemMeta();
// change the meta now
someItem....
yes
simple anvil
```java
ItemMeta meta = someItem.getItemMeta();
// change the meta now
someItem....
a week ago i did not know this.
i spent a 2or 3 hours trying to enchant somthing
tender shard
so when do i use array
you use an array if the method you want to use requires an array, OR if you do not need any of the special methods a list provides
so tl;dr: use an array unless you actually need a list 😛
I know it's a stupid explanation
simple anvil
OR if you do not need any of the special methods a list provides
its not and, why not just always use a list even if you dont need the features?
the code works @tender shard @young knoll thanks
tender shard
arrays are faster. but you don't have to worry about that in 99.999% of cases
simple anvil
ok
tender shard
you should however understand the difference between the two things anywaya
oh wait
wrong link
simple anvil
also, shoud the command be /addlore /setlore /lore /loreadd
tender shard
also, shoud the command be `/addlore` `/setlore` `/lore` `/loreadd`
well make the commands however you like. I'd do it like this:
/lore - show help message
/lore set - replaces current lore with the new args
/lore add - appends the new args to the current lore
also
tender shard
format that shit @ivory sleet
tender shard
I'll copy it
simple anvil
when i make a new package, the one highlighted, why does it do stuff.more stuff
tender shard
ClassName[] array;
//from are to list
List<ClassName> l1 = Arrays.asList(array); //fixed size
List<ClassName> l2 =new ArrayList<>(Arrays.asList(array)); //resizable (most likely you always want this)
List<ClassName> list;
//form list to arr
ClassName[] a = list.toArray(new ClassName[0]);
Thanks 🙏
simple anvil
when i was making a command open inv and open enderchest
i put it in the command package
and a made a new packing called openinventory
but then i could not add stuff to the command package
tender shard
so yeah the basic difference between array and list:
- array has a fixed size. if you have an array with a length of 5, it holds 5 elements. you can't just add a 6th element. in most lists, that's no problem, you can just append to them, etc
- list has nice methods like "add something between 2nd and 3rd element". arrays don't have that, you'll have to create a new array, copy the old content, etc
- arrays are faster though. they are "builtin" to java while lists always have some structures like an array in the background. so tl;dr: a list basically is a "wrapper" for an array that provides so you some convenient methods at the cost of more ram/cpu usage although you don't have to worry about that 99% of the time
tender shard
proper way is to restart it
lazy way is to enter /reload
lazy way MIGHT cause problems though
tender shard
spigot was not designed to reload plugins at runtime. while it might work fine, there's always a chance for it to cause memory leaks or other bad things. in the worst case, you get unexpected behaviour. your plugin might bug out and you don't know why. then you spend 3 hours debugging it while it would have worked if you would have just restarted the server
simple anvil
i will remember that
tender shard
(to test simple plugins, reload is fine most of the time)
simple anvil
well make the commands however you like. I'd do it like this:
```
/lore - show ...
also should i make a new classes for all these command or put them all in the same class
also is adding lore smp? or smp worthy?
tender shard
also should i make a new classes for all these command or put them all in the sa...
it depends. Do those commands belong together? do they share any common "dependencies" etc? Are your command classes 1000 lines long or only 5 lines? etc etc
tender shard
also is adding lore smp? or smp worthy?
"smp worthy"? wdym?
tender shard
also should i make a new classes for all these command or put them all in the sa...
Let me say something to this again pls
simple anvil
like, if i put it on a smp would people get mad
tender shard
imagine you have a command /sethome and /home. Both commands obviously have to access some List / HashMap or similar that stores all existing homes. If the sethome method already stores that list in its instance, I'd probably make both commands into one class. (Although you'd normally probably want to have a separate class manage the existing homes).
If however you have one command for /sethome and another one for /heal (so two entirely different commands), I wouldn't put them into one class
simple anvil
ok so all in the same class?
tender shard
like, if i put it on a smp would people get mad
I don't think so, changing a lore doesn't really change the gameplay at all
simple anvil
ok good
tender shard
ok so all in the same class?
If you just want to do lore stuff, I'd do only ONE command, which is /lore
and then it'd have different subcommands
/lore add
/lore remove
/lore set
I'd do all this in one class
simple anvil
how do i make sub commands
tender shard
you know, if someone enters this:
/say my name is jeff
then args[0] will be "my"
so you can just check what args[0] is

any question?

I don't really understand
what exactly is the problem?
oooh
I understand
easiest but dirty solution would be to just remove "set " from the string
like, just remove the first 4 characters from your string
simple anvil
apend?
tender shard
line = line.substring(4);
will remove everything before the 4th character
the "proper" solution would be to ignore the first array's element or to "shift" your array
but tbh that's just making things more complicated
I'd just substring(4) the string
simple anvil
I'd just substring(4) the string
how

quaint mantle
in your command class or main class if u wanna use it

you have a command executor class and you registered using setExecutor(). you can do the same thing with a class that implements TabCompleter or sth like that

yes
young knoll
Mhm
simple anvil
how do i even use that
quaint mantle
how do i even use that
intellij should generate the methods for u
let it
just implement TabExecutor and look at ur warnings
tender shard
basically you just need to override onTabComplete, like you did with onCommand. Here's an overcomplicated, incomplete, dirty example:
@Override
public @Nullable List<String> onTabComplete(@NotNull final CommandSender commandSender, @NotNull final Command command, @NotNull final String s, @NotNull final String[] args) {
final List<String> list = new ArrayList<>();
UUID uuid = commandSender instanceof Player ? ((Player) commandSender).getUniqueId() : Main.consoleSenderUUID;
if (args.length == 1) {
for (int i = 1; i <= getChests(uuid); i++) {
if (String.valueOf(i).startsWith(args[0])) {
list.add(String.valueOf(i));
}
}
if (commandSender.hasPermission(Permissions.OTHERS)) {
for (final Player player : Bukkit.getOnlinePlayers()) {
if (player.getName().startsWith(args[0])) {
list.add(player.getName());
}
}
}
}
// ...
return list;
@Override
public List<String> onTabComplete(CommandSender sender, Command command, String label, String[] args) {
return null;
}
```now whatnow you return a list with all the tab suggestions
quaint mantle
```java
@Override
public List<String> onTabComplete(CommandSender sender, Co...
using the arguments provided you do some logic and return a list of strings, being the tab complete suggestions
quaint mantle
no problem
tender shard
e.g. if you a return a list "a" "b" "c" it will suggest "a" "b" and "c" as tab completion
and stop saying "danke" if you don't understand "bitte"
