ParticleEmitter

ParticleEmitter

A ParticleEmitter allows for the creation of particle systems. is a special effect object that emits customizable 2D billboard particles into the world. On Roblox, a particle is a 2D image rendered in the world so that it always always face the camera, much like a BillboardGui with a single ImageLabel in it.

ParticleEmitter must be parented to a BasePart (such as a Part) or an Attachment within such a part. Particles spawn randomly in the bounding box of its parent part (for attachments, this is a single point). Particles from a single emitter will render so long as this condition is met; setting a ParticleEmitter’s Instance/Parent to nil will remove all particles instantly, like how ParticleEmitter/Clear works. If an emitter is ParticleEmitter/Enabled and has a nonzero ParticleEmitter/Rate, it will emit particles on its own. Finer control on the number of particles can be accomplished using ParticleEmitter/Emit.

Roblox provides several pre-made particle effect objects - Fire, Smoke and Sparkles. They behave similarly to a ParticleEmitter, but they are not as customizable. They also lack certain particle-controlling methods: ParticleEmitter/Emit and ParticleEmitter/Clear. An Explosion also uses particles, but provides little-to-no control with regards to how the effect looks.

How to Insert a ParticleEmitter

In Studio, a ParticleEmitter can be inserted in several ways:

  • Using the “Effects” drop-down (Model tab)
  • From the Advanced Objects window (In the model tab, or CTRL+I)
  • The add menu within the Explorer window
  • Using the Command bar, run Instance.new("ParticleEmitter", workspace)
  • If you find you are inserting ParticleEmitters often, you can add a ParticleEmitter button to the Quick Access toolbar
