Emit
For thread safety, this property is not safe to read in an unsynchronized thread.
The Emit method will cause the ParticleEmitter
to emit the given number of particles similar to how ParticleEmitter/Rate
does on ParticleEmitter/Enalbed
emitters. Be warned - this always emits exactly the number of particles even if Roblox’ graphics settings are lower. Emitting too many particles can cause performance issues on lower-end hardware.
To clear any emit particles, use ParticleEmitter/Clear
.
Parameters
Name | Type | Default | Description |
---|---|---|---|
16
|
The number of particles to emit |
Returns

Code Samples
ParticleEmitter Burst
This code sample causes a ParticleEmitter
to ParticleEmitter/Emit
particles in bursts of 10 every 2 seconds. It ParticleEmitter/Clear
s any existing particles before doing so.
local emitter = script.Parent while true do emitter:Clear() emitter:Emit(10) wait(2) end
When run, the script should emit a burst of 10 particles every 10 seconds, clearing before each new emission.
Emit Particles Over Distance
This code sample causes a parent ParticleEmitter
to ParticleEmitter/Emit
particles based on how far the parent BasePart
moves.
local RunService = game:GetService("RunService") local emitter = script.Parent local part = emitter.Parent local PARTICLES_PER_STUD = 3 local lastPosition = part.Position local distance = 0 local function onStep() local displacement = part.Position - lastPosition distance = distance + displacement.magnitude local n = math.floor(distance * PARTICLES_PER_STUD) emitter:Emit(n) distance = distance - n / PARTICLES_PER_STUD lastPosition = part.Position end RunService.Stepped:Connect(onStep) emitter.Enabled = false
While the script is running, moving the part should cause 3 particles to be emit per stud that the part moves.
