so

#

public static void makeParticleCircle() {
        for (Player p : Bukkit.getOnlinePlayers()) {
            Location location = p.getPlayer().getLocation();
            for (int degree = 0; degree < 360; degree++) {
                double radians = Math.toRadians(degree);
                double x = Math.cos(radians);
                double z = Math.sin(radians);
                location.add(x, 0, z);
                location.getWorld().spawnParticle(Particle.END_ROD, location, 0);
                location.subtract(x, 0, z);
            }
        }
    }

#

@amber cradle

#

and now?

amber cradle Mar 6, 2022, 7:33 PM

#

You need to parameterize the method with a radius and height-offset

storm lantern Mar 6, 2022, 7:34 PM

#

ok

#

public static void makeParticleCircle(double x, double z, double y, double radius) {
        for (Player p : Bukkit.getOnlinePlayers()) {
            Location location = p.getPlayer().getLocation();
            for (int degree = 0; degree < 360; degree++) {
                double radians = Math.toRadians(degree);
                x = Math.cos(radians);
                z = Math.sin(radians);
                location.add(x, 0, z);
                location.getWorld().spawnParticle(Particle.END_ROD, location, 0);
                location.subtract(x, 0, z);
            }
        }
    }
```this?

amber cradle Mar 6, 2022, 7:36 PM

#

You should not use 360 points for every circle. You should scale that based on the radius.
Btw this will create a circle for every player on the server. Do you really want that?

storm lantern Mar 6, 2022, 7:37 PM

#

no

#

i made a thing to make it run only at players wearing a custom helmet

#

but lets pretend its for all players

amber cradle Mar 6, 2022, 7:38 PM

#

You should probably add the player as a parameter too

#

So you can call that method for each player

storm lantern Mar 6, 2022, 7:39 PM

#

ok

#

 public static void makeParticleCircle(double x, double z, double radius, Player p) {

            Location location = p.getPlayer().getLocation();
            for (int degree = 0; degree < 360; degree++) {
                double radians = Math.toRadians(degree);
                x = Math.cos(radians);
                z = Math.sin(radians);
                location.add(x, 0, z);
                location.getWorld().spawnParticle(Particle.END_ROD, location, 0);
                location.subtract(x, 0, z);
            }
        }
    }

#

this?

amber cradle Mar 6, 2022, 7:41 PM

#

Looks ok.
Now we need to write a second method that generates the sin wave based on the distance from the player

#

So
input -> distanceFromPlayer
output -> heightOfWave

#

Then we step from 0 to N in steps of 0.1 or so and then generate a circle with this radius and height

amber cradle Mar 6, 2022, 7:43 PM

#

storm lantern ```java public static void makeParticleCircle(double x, double z, double radius...

Btw this method is not done. The parameters x and z are useless. You need y for the height offset.

storm lantern Mar 6, 2022, 7:43 PM

#

i put input as parameter of method right?

storm lantern Mar 6, 2022, 7:44 PM

#

amber cradle Btw this method is not done. The parameters x and z are useless. You need y for ...

so i can remove them?

#

x and z made the circle

amber cradle Mar 6, 2022, 7:47 PM

#

    public static void makeParticleCircle(double heightOffset, double radius, Player player) {
        Location location = player.getLocation();
        for (int degree = 0; degree < 360; degree++) {
            double radians = Math.toRadians(degree);
            double x = Math.cos(radians) * radius;
            double z = Math.sin(radians) * radius;
            location.add(x, heightOffset, z);
            location.getWorld().spawnParticle(Particle.END_ROD, location, 0);
            location.subtract(x, heightOffset, z);
        }
    }

storm lantern Mar 6, 2022, 7:50 PM

#

ill test it wait

amber cradle Mar 6, 2022, 7:51 PM

#

    public static void makeParticleCircle(double heightOffset, double radius, Player player) {
        Location location = player.getLocation();

            rad += steps;
        }
    }

storm lantern Mar 6, 2022, 7:51 PM

#

oh

amber cradle Mar 6, 2022, 7:52 PM

#

Usage:

createParticleWave(player, 1.0, 5.0, 0.1);

#

Creates a wave from distance 1.0 - 5.0 in 0.1 steps

storm lantern Mar 6, 2022, 7:52 PM

#

ok

#

1.0 from player?

#

1.0 blocks?

#

and what is steps

#

also

#

is there a way to make it take time?

#

like take 5seconds to complete the circle

#

um

#

was this meant to happen?

#

@amber cradle

#

@Flo | Gestankbratwurst#4120 ?

#

i wanted it to make this

#

@amber cradle ?

amber cradle Mar 6, 2022, 8:25 PM

#

storm lantern i wanted it to make this

Oh this is something completely different

storm lantern Mar 6, 2022, 8:26 PM

#

;-;

#

you know it?

amber cradle Mar 6, 2022, 8:26 PM

#

This should be simpler

storm lantern Mar 6, 2022, 8:26 PM

#

yay

#

can you tell me how?

amber cradle Mar 6, 2022, 8:27 PM

#

Try this:

    public static void makeParticleSinCircle(double radius, Player player) {
        Location location = player.getLocation();
        for (int degree = 0; degree < 360; degree++) {
            double radians = Math.toRadians(degree);
            double x = Math.cos(radians) * radius;
            double y = Math.sin(radians);
            double z = Math.sin(radians) * radius;
            location.add(x, y, z);
            location.getWorld().spawnParticle(Particle.END_ROD, location, 0);
            location.subtract(x, y, z);
        }
    }

storm lantern Mar 6, 2022, 8:27 PM

#

just it?

amber cradle Mar 6, 2022, 8:27 PM

#

Just this yes

storm lantern Mar 6, 2022, 8:28 PM

#

kk

amber cradle Mar 6, 2022, 8:29 PM

#

It might look a bit odd because its just a single sin wave.

storm lantern Mar 6, 2022, 8:29 PM

#

storm lantern um

oh wait
this made part of what i wanted

amber cradle Mar 6, 2022, 8:30 PM

#

pic pls

storm lantern Mar 6, 2022, 8:30 PM

#

i increased the steps amount and it taked time to make the circle

storm lantern Mar 6, 2022, 8:30 PM

#

amber cradle pic pls

of what

storm lantern Mar 6, 2022, 8:30 PM

#

storm lantern um

this makes only a normal circle, but takes time to make it

amber cradle Mar 6, 2022, 8:30 PM

#

The new method ive sent

storm lantern Mar 6, 2022, 8:30 PM

#

yea ok wait

storm lantern Mar 6, 2022, 8:31 PM

#

storm lantern this makes only a normal circle, but takes time to make it

would be very nice if i could mix the new method and the old one

#

so it would make the waves and take time to make them

#

amber cradle Mar 6, 2022, 8:33 PM

#

Ah i see.

#

Change

double y = Math.sin(radians);

to

double y = Math.sin(radians * 4);

storm lantern Mar 6, 2022, 8:34 PM

#

radians * number
number is waves?

amber cradle Mar 6, 2022, 8:35 PM

#

Yes the number should be the amount of waves

storm lantern Mar 6, 2022, 8:35 PM

#

so i can add it as parameter?

amber cradle Mar 6, 2022, 8:35 PM

#

sure

storm lantern Mar 6, 2022, 8:35 PM

#

 public static void makeParticleSinCircle(double radius, Player player, int waves) {
        Location location = player.getLocation();
        for (int degree = 0; degree < 360; degree++) {
            double radians = Math.toRadians(degree);
            double x = Math.cos(radians) * radius;
            double y = Math.sin(radians) * waves;
            double z = Math.sin(radians) * radius;
            location.add(x, y, z);
            location.getWorld().spawnParticle(Particle.END_ROD, location, 0);
            location.subtract(x, y, z);
        }
    }

#

ty

#

nah u pro

amber cradle Mar 6, 2022, 8:39 PM

#

nice. I would just decrease the number of points a bit.

for (int degree = 0; degree < 360; degree++) {

Could be

for (int degree = 0; degree < 360; degree += 4) {

To have 90 points instead of 360

storm lantern Mar 6, 2022, 8:39 PM

#

less particles right?

amber cradle Mar 6, 2022, 8:39 PM

#

yeah

storm lantern Mar 6, 2022, 8:39 PM

#

kk

#

not everyone has a non-potato pc

#

thanks for help

#

@amber cradle

#

how do i change the height offset

#

its too big

amber cradle Mar 6, 2022, 8:43 PM

#

double y = Math.sin(radians * waves) * height;

storm lantern Mar 6, 2022, 8:44 PM

#

ok

#

gg thanks

#

storm lantern Mar 7, 2022, 10:33 PM

#

amber cradle ```java public static void makeParticleCircle(double heightOffset, double ra...

how would i mix this

#

with this

    public static void makeParticleSinCircle(double radius, Player player, int waves, double heightOffset) {
        Location location = player.getLocation();
        for (double degree = 0.0; degree < 360.0; degree+=4) {
            double radians = Math.toRadians(degree);
            double x = Math.cos(radians) * radius;
            double y = Math.sin(radians * waves) * heightOffset;
            double z = Math.sin(radians) * radius;
            location.add(x, y, z);
            location.getWorld().spawnParticle(Particle.END_ROD, location, 0);
            location.subtract(x, y, z);
        }
    }

storm lantern Mar 8, 2022, 12:45 PM

#

@amber cradle?

#

I want to do the wave circle (that i already have) but with the steps from the other

storm lantern Mar 8, 2022, 11:15 PM

#

@amber cradle

amber cradle Mar 8, 2022, 11:15 PM

#

Oh yeah. Idk just throw some math at it...

#

What are you trying to do?

storm lantern Mar 8, 2022, 11:15 PM

#

Im not he math guy here

storm lantern Mar 8, 2022, 11:16 PM

#

storm lantern with this ```java public static void makeParticleSinCircle(double radius, Pl...

This with steps

amber cradle Mar 8, 2022, 11:17 PM

#

So you want a wave that goes outwards + has waves on a radial axis?
This will just result in random hills...

storm lantern Mar 8, 2022, 11:17 PM

#

No

storm lantern Mar 8, 2022, 11:17 PM

#

storm lantern

This

#

But it takes some time to complete the circle

amber cradle Mar 8, 2022, 11:18 PM

#

What do you mean by that? The circle should show instantly.

storm lantern Mar 8, 2022, 11:19 PM

#

amber cradle ```java public static void makeParticleCircle(double heightOffset, double ra...

This one didnt

#

Steps made it take some time to complete

#

I want it do "draw" the wave circle

amber cradle Mar 8, 2022, 11:22 PM

#

So you want it to appear over time?

#

Like a laser pointer going in a circle

storm lantern Mar 8, 2022, 11:22 PM

#

Yes

#

But waveing y axis

amber cradle Mar 8, 2022, 11:23 PM

#

Oh i wont help with that. Its basically the same thing but you create a stateful runnable.

storm lantern Mar 8, 2022, 11:24 PM

#

I think i can just mix both things u sent me

amber cradle Mar 8, 2022, 11:24 PM

#

storm lantern I think i can just mix both things u sent me

Nope

#

You will need a scheduler for that

storm lantern Mar 8, 2022, 11:24 PM

#

I mean

storm lantern Mar 8, 2022, 11:25 PM

#

amber cradle ```java public static void makeParticleCircle(double heightOffset, double ra...

I didnt need it for this

storm lantern Mar 8, 2022, 11:25 PM

#

amber cradle So you want it to appear over time?

And it still made this

#

Just increased steps

amber cradle Mar 8, 2022, 11:27 PM

#

Thats probably just lags showing. You need a runnable. Trust me on that.

storm lantern Mar 8, 2022, 11:42 PM

#

Kk

storm lantern Mar 8, 2022, 11:45 PM

#

amber cradle ```java public static void makeParticleCircle(double heightOffset, double ra...

Tomorrow ill try this with 360 steps

#

If it doesnt make the circle instantly then its not lag

storm lantern Mar 8, 2022, 11:46 PM

#

amber cradle Thats probably just lags showing. You need a runnable. Trust me on that.

And i have no idea of how to do this

#

Im probably already doing it and dont know

#

public class ArmorTask extends BukkitRunnable

storm lantern Mar 9, 2022, 8:05 PM

#

storm lantern Tomorrow ill try this with 360 steps

mhm yea it didnt

storm lantern Mar 9, 2022, 8:05 PM

#

amber cradle Thats probably just lags showing. You need a runnable. Trust me on that.

how would i do it

amber cradle Mar 9, 2022, 8:26 PM

#

You will need 2 classes.
For once the task:

import org.bukkit.Bukkit;
import org.bukkit.Location;
import org.bukkit.Particle;
import org.bukkit.entity.Player;
import org.bukkit.scheduler.BukkitRunnable;

import java.util.UUID;

public class WaveParticleTask extends BukkitRunnable {

    private final UUID playerID;
    private final int waves;
    private final double height;
    private final double radius;
    private int degree = 0;

    public WaveParticleTask(UUID playerID, int waves, double height, double radius) {
        this.playerID = playerID;
        this.waves = waves;
        this.height = height;
        this.radius = radius;
    }

    @Override
    public void run() {
        degree %= 360;
        Player player = Bukkit.getPlayer(playerID);
        if (player == null) {
            this.cancel();
            return;
        }
        double radians = Math.toRadians(degree);
        double x = Math.cos(radians) * radius;
        double y = Math.sin(radians * waves) * height;
        double z = Math.sin(radians) * radius;
        Location particleLoc = player.getLocation().add(x, y, z);
        player.getWorld().spawnParticle(Particle.END_ROD, particleLoc, 0);
        degree += 5;
    }

}

#

Then a manager:

import org.bukkit.entity.Player;
import org.bukkit.scheduler.BukkitRunnable;

import java.util.HashMap;
import java.util.Map;
import java.util.Optional;

public class WaveParticleManager implements Runnable {

    private final Map<Player, WaveParticleTask> runningTasks = new HashMap<>();

    public void startTask(Player player) {
        runningTasks.put(player, new WaveParticleTask(player.getUniqueId(), 5, 0.66, 2.5));
    }

    public void stopTask(Player player) {
        Optional.ofNullable(runningTasks.get(player)).ifPresent(BukkitRunnable::cancel);
    }

    @Override
    public void run() {
        runningTasks.values().forEach(WaveParticleTask::run);
    }

}

#

Then you can do this in your main class:

    private final WaveParticleManager waveParticleManager = new WaveParticleManager();

    @Override
    public void onEnable() {
        Bukkit.getScheduler().runTaskTimer(this, waveParticleManager, 1, 1);
    }

#

If you want to start a wave task simply do:

waveParticleManager.startTask(player);

storm lantern Mar 9, 2022, 8:31 PM

#

kk

#

thanks

#

i found another way

#

but its very big

#

Then a manager:
cannot resolve symbol 'Then'

#

nvm

#

i copied wrong

storm lantern Mar 9, 2022, 8:47 PM

#

amber cradle If you want to start a wave task simply do: ```java waveParticleManager.startTas...

onEnable?

#

if yes: cannot resolve symbol ''player''

#

public void onEnable() {
        instance = this;
        CustomArmorManager.startTask(player);
//cannot resolve symbol player
//Non-static method 'startTask(org.bukkit.entity.Player)' cannot be referenced from a static context
        Setup.setup(this);
    }

#

i changed some things and got no errors
