Emit

Unsafe

For thread safety, this property is not safe to read in an unsynchronized thread.

Function of:

Description:

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
Name particleCount	Type int	Default 16	Summary The number of particles to emit

Returns

Return Type	Summary
Return Type void	Summary

Code Samples

ParticleEmitter Burst

This code sample causes a ParticleEmitter to ParticleEmitter/Emit particles in bursts of 10 every 2 seconds. It ParticleEmitter/Clears any existing particles before doing so.

			
				ParticleEmitter Burst

				Expected Output
			
				Expand
				
			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.

			
				Emit Particles Over Distance

				Expected Output
			
				Expand
				
			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.
