Particle Helix by Vector

After seeing the incredible particle resource by Skionz, I can't help wondering if there is any way to make the same helix, but instead of going straight up, have it going in the direction a player is facing? I'm terrible with that kind of thing (trig) so any help would be appreciated.

 

I don't get what you want, it will loop in the player facing direction?

 

A spiral coiled around the player's line of sight

Honestly, you could just swap the x and y values and that would get you started, although it would be fixed to one axis, not lining up with the player's line of sight.

 

Mysticate Yea this would be complicated but pretty badass

 

Skionz Barinade mythbusterma Yeah... I was thinking about using it when a player shoots a fireball so it circles around it as it goes through the air.

EDIT: ChipDev, I want to know how to make the helix/spiral point in the direction that the player is looking at... Any ideas?

 

It's been a long time since I've done anything with Bukkit but I'm gonna give this a shot.

 

That seems hard... You can use LCastr0 's EffectLib (Made by Slikey) using the cone effect!

 

Rotate the vector in the way the player is facing (I currently do it using VectorUtils and MathUtils, in EffectLib, which you can find here: http://forums.bukkit.org/threads/ef...-the-nice-way-text-image-in-particles.259879/ )

Code:java

 
VectorUtils.rotateAroundAxisX(<vector>, (<player/location><.getLocation(), if its a player>.getPitch() + 90) * MathUtils.degreesToRadians);
VectorUtils.rotateAroundAxisY(<vector>, -<player/location><.getLocation()>.getYaw() * MathUtils.degreesToRadians);
 

 

LCastr0 But how do I use that?

 

Just put it in your code, the methods will do everything for you.
After you place this code, spawn the helix at the location you want and .add(<vector>);

 

LCastr0 Is there any way to do it without EffectLib?

 

You could look the source of the VectorUtils and MathUtils and just get the parts of the code that you need (rotateroundAxisX and Y, degreesToRadians)

 

LCastr0 But how do I use that in relation to Skionz 's code?

Code:

public void createHelix(Player player) {
    Location loc = player.getLocation();
    int radius = 2;
    for(double y = 0; y <= 50; y+=0.05) {
        double x = radius * Math.cos(y);
        double z = radius * Math.sin(y);
        PacketPlayOutWorldParticles packet = new PacketPlayOutWorldParticles("fireworksSpark", (float) (loc.getX() + x), (float) (loc.getY() + y), (float) (loc.getZ() + z), 0, 0, 0, 0, 1);
        for(Player online : Bukkit.getOnlinePlayers()) {
            ((CraftPlayer)online).getHandle().playerConnection.sendPacket(packet);
        }
    }
}

 

Code:

Location loc = player.getLocation();
Vector v = new Vector(0, 0, 0);
<rotate the vectors like I explained above>
loc.add(v);
<then just use the rest of your code>

 

LCastr0 but it doesn't do anything other than circle up...

Code:

public void createHelix(Player player) {
        Location loc = player.getLocation();
        Vector v = new Vector(0, 0, 0);
        rotateAroundAxisX(v, (player.getLocation().getPitch() + 90) * degreesToRadians);
        rotateAroundAxisY(v, (player.getLocation().getYaw()) * degreesToRadians);
        loc.add(v);
        int radius = 2;
        for(double y = 0; y <= 50; y+=0.05) {
            double x = radius * Math.cos(y);
            double z = radius * Math.sin(y);
            PacketPlayOutWorldParticles packet = new PacketPlayOutWorldParticles("fireworksSpark", (float) (loc.getX() + x), (float) (loc.getY() + y), (float) (loc.getZ() + z), 0, 0, 0, 0, 1);
            for(Player online : Bukkit.getOnlinePlayers()) {
                ((CraftPlayer)online).getHandle().playerConnection.sendPacket(packet);
            }
        }
    }

 

Mysticate Thats cause your incrementing y

 

Mysticate

Did you completely ignore my above post?

 

Of course, LCastr0 saves the day

 

You have to increment either X or Z, not Y, as Skionz said.

 

The EffectLib has the Vortex effect, doing exactly what you want.

 

No, I think he wants a cone effect not incrementing its radius.
