(danjoe3) Animate Particle Learning

[slow wind]

Hey there,
I just wanted to explore particles and animate them because I'm starting to have a grasp on Denizen scripting. I know it involves a lot of maths, which I don't know very well. Is there any possibility that I could learn the fundamentals and what I might need to go through? I've gone through the Halo script that was there in the forums, and I intend on testing on that for sometime too.

Hi I'm AutoThreadBot! Don't mind me, I'll just be adding the helper team to this thread so they can see it. A human will get to you soon.

Did you have any goals in mind? There's many ways to do particle animations

[slow wind]

Well, I'm trying to possibly try and recreate all these particles to Denizen -> https://www.spigotmc.org/resources/playerparticles.40261/ . I understand that it is a free plugin, but I thought I'd try and learn creating particles using Denizen script while having these as examples

[queen nova]

looks like the plugin is open source, which is a good reference if you'd want to recreate some of them in denizen

i remember a particle library being somewhere as well

in essence though, doing anything related to particles in a unique way is related to graphing in 2D or 3D space one way or another

having knowledge on either of those is a great foundation to have in order to understand what, and why people code particle animations the way they do

just for starters this command will make a fire circle around your feet

playeffect effect:flame at:<player.location.points_around_y[radius=2;points=90]> offset:0

sometimes there are tags that can make doing these easier

[queen edge]

If you don't wanna deal with maths there are also pre-made effect libraries like EffectLib

!c effectlib

[fluid roost]

Command: effectlib

Required Plugins or Platforms

Depenizen, EffectLib

Group

Depenizen

Syntax

effectlib [type:<effect>] (origin:<entity>/<location>) (target:<entity>/<location>) (for:<player>) (effect_data:<map>)

Short Description

Show custom effects using EffectLib

Description

Displays EffectLib effects.

Specify which effect to display using the 'type:' argument, note that effect names are CASE-SENSITIVE.

The origin is the entity/location to play the effect at. If an entity is specified, the effect will follow it.
Defaults to the linked player if unspecified.

Some effects (such as the 'Line' effect) require an origin and a target, an effect's target can be a location or an entity.
If an entity is specified, the effect will follow it.

You can optionally use the 'fo...

Yeah, thats what I thought but I'd have to check if there are specific tags or syntax's that would help me recreate something like that to Denizen

Oops, I'm sorry about the ping!

Meant to remove it

[slow wind]

I've tested this and I've made a helix particle effect too. But I'm trying to learn more and the maths around it, cuz I'm terrible at maths 😬

[slow wind]

I think I've gone through that, but I wouldn't have total control over the particle right?

[grizzled dirge]

one tag you'll use a lot is rotate_around_(xyz)

!t location.rotate_around

[fluid roost]

Cannot Specify Searched Tag

Multiple possible tags: <LocationTag.rotate_around_x[<#.#>]>, <LocationTag.rotate_around_y[<#.#>]>, <LocationTag.rotate_around_z[<#.#>]>.

[grizzled dirge]

all of those

the only trick with them is that they rotate with 0,0,0 as their axis

no clue if im englishing correctly so pardon me if i say anything wrong

[grizzled dirge]

so you need to either already use vectors in the start of the script, or turn those locations into vectors (can be a bit complicated)

bc lets imagine you want to rotate a location along the player, but that player is in 100,100,100

all of those tags would instead rotate it along 0,0,0

so you'd get the rotated particle WAAAY off

i generally use <location[0,0,0]> as my starting point

in some of my scripts there's literally
- define 000 <location[0,0,0]> because i know i'll be using that for rotations later

then, lets say i want the particle to be one block above the player

ez, <[000].above>

now, that's a vector

you cant play a particle at a vector

so to actually give it a place, we'll do

<[000].above.add[<player.location>]>

- define 000 <location[0,0,0]>
- repeat 4:
  - define points:->:<[000].forward.rotate_around_y[<[value].mul[90].to_radians>]>
- define points <[points].parse[add[<player.location>]]>

wrote this rq

it gets 000, creates a point at .forward, and then rotates it 90 degrees across the y axis every loop

then turns all those vectors into real locations by adding a real location to them

that should be a square

now, vectors can be modified in many, many ways

one of the most useful is to multiply them

remember real vectors in high school? when you multiply a vector, it has more or less strength, depending on what you multiply it at

so if you get that script i sent you and do .parse[mul[0.5]], it'll now be half as big as it was before

[slow wind]

Oh wow, all this is truly helpful!

[slow wind]

Sadly I don't remember them anymore. It's been 3-4 years, and I still despise maths 😬

But yes, I'll look into these and create other threads to possibly see how I can get better at making particles! Thank you so much though :))
