The module contains several methods to generate particles without needing premade video files. The particles are simple sprite textures managed by script. You can use or add some prefill templates for the emitter or customize it with a JSON input.

 particlesFx.sprayParticles('breath', {source: token.id, target: target.id})

• v2.1.0: We added advanced mode to link multiple inputs together and change the static value with dynamic functions.
• v2.2.0: We added automatic emission settings. Particles can be generate on items usage (Only existing on DnD 5e).
• v2.3.0:
  • We added elevation to particles.
  • We improved the particle texture.
  • We migrate to foundry v12 (mandatory) and dnd5e v4 (optionnal) 

1. Avoid showing particle from other client (useful for minimal configuration) (Client setting)
2. Save emitters when changing scene and retrieve when returning (World setting)
3. Define minimal user role to manage the custom prefill templates (World setting)
4. Automatic generate emission when using items (Client setting) (Only existing on DnD 5e)
5. Activate elevation management for particle (useful for minimal configuration) (Client setting)
6. Elevation to double the size of a particle in grid number (World setting)
    

The emission methods are used to interpret the input and manage the particles during their lifetime. The method returns its ID.

Spray particles are emitted from a source and move with a velocity in a direction defined by an angle.

Gravitating particles turn around the source with a velocity at a distance defined by a radius.

The missile method emits spray particles that are used to emit sub-particles.

To stop all emissions in the scene and reset the particle emitter's IDs index.

To stop a specific emission, you need to use a macro to call the method particlesFx.stopEmissionById with an ID parameter:

• ID of the emission (returned by the method)
• 'l' or 'last' for newest emission
• 'f' or 'first' for oldest emission And a boolean parameter, true for instant deletion of particles already emitted, false to stop only the emission (living particles are not killed).

You can start or stop emission by chat with the command "/pfx". It adds a message response in the chat.

Commands:

• /pfx stopAll
• /pfx stopById *id*
• /pfx spray *prefillMotionTemplate* *prefillColorTemplate*
• /pfx gravitate *prefillMotionTemplate* *prefillColorTemplate*
• /pfx missile *prefillMotionTemplate* *prefillColorTemplate*
• /pfx help

/pfx spray ray death

To stop a command, you can add the param --instant to not have to wait the end of the particles lifetime.

• To emit spray particles, you need to use a macro to call the method particlesFx.sprayParticles(prefillMotionTemplateName, prefillColorTemplate, {Advanced options})
• To emit gravitating particles, you need to use a macro to call the method particlesFx.gravitateParticles(prefillMotionTemplateName, prefillColorTemplate, {Advanced options})
• To emit missile particles, you need to use a macro to call the method particlesFx.missileParticles(prefillMotionTemplateName, prefillColorTemplate, {Advanced options}). Advanced options have the same input as Spray particles with a nested object subParticles containing another input (spray or gravitating) and type (equals to "Spraying" or "Graviting").
• Write a message to describe the emitter and a button to stop it particlesFx.writeMessageForEmissionById(emitterId, isVerbal). The isVerbal parameter also writes advanced input in the message.
• To stop all emissions, you need to use a macro to call the method particlesFx.stopAllEmission(instantDelete). instantDelete is a boolean parameter, if true, it deletes all particles already emitted, false to stop only the emission (living particles are not killed).
• To stop a specific emission, you need to use a macro to call the method particlesFx.stopEmissionById(id). ID is a number or a string:
  • ID of the emission (returned by the method)
  • 'l' or 'last' for the newest emission
  • 'f' or 'first' for the oldest emission

Example To emit missile particles with gravitating sub particles that form a trail particlesFx.missileParticles({source: {x:200, y:250}, target: token.id, subParticles: {type: "Gravitating", particleLifetime: 1000, onlyEmitterFollow: true, particleAngleStart: '0_360'}})

All these methods can also be called with the module's API game.modules.get("particule-fx").api with the same parameters and behavior:

• xxx.api.emit.spray(xxx)
• xxx.api.emit.gravit(xxx)
• xxx.api.emit.missile(xxx)
• xxx.api.emit.writeMessage(xxx)
• xxx.api.emit.stopAll(xxx)
• `xxx.api.emit.stop(xxx)

The method emitting particles can be called with a prefill template. There are two kinds of templates: prefillMotionTemplate and prefillColorTemplate, which can be combined. You can add an input to override some attributes of the prefill template. The order of the parameters is not important.

Prefill Motion Template:

• explosion (designed for spray)
• breath (designed for spray)
• ray (designed for spray)
• sonar (designed for spray)
• trail (designed for missile)
• wave (designed for missile)
• grow (designed for missile)
• vortex (designed for gravitate)
• aura (designed for gravitate)
• satellite (designed for gravitate)
• slash (designed for gravitate)

Example particlesFx.missileParticles('wave', {source: token.id, target: target.id})

Prefill Color Template:

• ice
• fire
• light
• death
• poison
• silver
• cyber

Example /pfx spray breath fire

For more advanced functionality, please read the WIKI for more details:

• More examples of how to use the module
• Add and manage custom prefill templates
• Particular behavior of measured templates as a source
• Customize all the parameters of the emitter to get exactly the animation you want

With the v2.0.0, all words containing particle have been renamed particle. And the object exposing the module's methods (particleEmitter) has been renamed particlesFx.

A compatibility management has been added with warnings to show the bad names.
