About

ParticleGenerator is a Minecraft mod created mainly for builders and mapmakers. It adds Particle Generator block into the game.

Particle Generator block is highly customisable and using it is much more convenient and efficient than using command blocks. It allows you to generate multiple particles from one block or set generated particles position and speed randomization.

Usage

Commands

/pgen show - Shows edges of Particle Generators
/pgen hide - Hides edges of Particle Generators
/pgen locate - Adds markers inside Particle Generators
/pgen info - Displays information about mod
/pgen help - Displays the help message with 

Particle Generator block states

position=[center(default)/top/bottom] - determines position of particles generation

Particle Generator NBT tags

Particles:[{...}] - list of compounds:
  id:"" - particle id
  Motion:[x,y,z] - particle velocities [blocks/tick] (in most cases)
  MotionRand:[x,y,z] - randomization of "Motion" values
  PositionOffset:[x,y,z] - offset of particle positions
  PositionRand:[x,y,z] - randomization of particle positions
  Interval:int - interval between particles [ticks]
  Probability:double - probability of particle spawning
  ParticleCount:int - number of particles when spawned
  ParticleMaxCount:int - maximum number of particles
  AdditionalTags:{} - additional tags (like block id)
UseAnimateTick:bool - spawn particles on animateTick

*For position and motion, random value is in range from val-(rand/2) to val+(rand/2).

*For particle count, random value is in range from ParticleCount to ParticleMaxCount.

*By default UseAnimateTick tag is set to false. That means particles will try to spawn every tick and their spawn rate can be manipulated using Interval and Propability tags. When set to true particles will try to spawn when animateTick method is called. This will allow you to recreate particles spawn rate of for example torches and many other blocks that uses animateTick to spawn particles.

*If you want to spawn particles that require additional block or item ID (like for example block particle) add tag AdditionalTags:{id:"some_block_id"} .

Useful Minecraft BlockItem NBT tags (pre-1.20.5)

BlockStateTag:{} - specifies block states
BlockEntityTag:{} - specifies block NBT tags

Useful Minecraft BlockItem data components (1.20.5+)

block_state:{...} - specifies block states
block_entity_data:{id:"pgen:particle_generator",...} - specifies block NBT tags

Examples

Simple smoke Particle Generator

Using /setblock: /setblock ~ ~ ~ pgen:particle_generator{Particles:[{id:"smoke"}],UseAnimateTick:true}

Using /give (pre-1.20.5): /give @p pgen:particle_generator{BlockEntityTag:{Particles:[{id:"smoke"}],UseAnimateTick:true}}

Using /give (1.20.5+): /give @p pgen:particle_generator[block_entity_data={id:"pgen:particle_generator",Particles:[{id:"smoke"}],UseAnimateTick:true}]

Particle Generator like campfire

Using /setblock: /setblock ~ ~ ~ pgen:particle_generator[position=bottom]{Particles:[{id:"campfire_cosy_smoke",Motion:[0.0,0.07,0.0],PositionRand:[0.67,0.0,0.67],ParticleCount:2,ParticleMaxCount:3,Probability:0.11}]}

Using /give (pre-1.20.5): /give @p pgen:particle_generator{BlockStateTag:{position:"bottom"},BlockEntityTag:{Particles:[{id:"campfire_cosy_smoke",Motion:[0.0,0.07,0.0],PositionRand:[0.67,0.0,0.67],ParticleCount:2,ParticleMaxCount:3,Probability:0.11}]}}

Using /give (1.20.5+): /give @p pgen:particle_generator[block_state={position:bottom},block_entity_data={id:"pgen:particle_generator",Particles:[{id:"campfire_cosy_smoke",Motion:[0.0,0.07,0.0],PositionRand:[0.67,0.0,0.67],ParticleCount:2,ParticleMaxCount:3,Probability:0.11}]}]

You can easily get these commands by using /pgen help and use them as a template.
