名前と書き方	説明
Acceleration `ParticleEmitter.Acceleration: Vector3`	Determines the global-axis acceleration of all active particles, measured in studs per second squared.
Brightness `ParticleEmitter.Brightness: float`	Scales the light emitted from the emitter when ParticleEmitter.LightInfluence is 0.
Color `ParticleEmitter.Color: ColorSequence`	Determines the color of all active particles over their individual lifetimes.
Drag `ParticleEmitter.Drag: float`	Determines the rate at which particles will lose half their speed through exponential decay.
EmissionDirection `ParticleEmitter.EmissionDirection: NormalId`	Determines the face of the object that particles emit from.
Enabled `ParticleEmitter.Enabled: boolean`	falseにすると粒子が出なくなります。Determines if particles emit from the emitter.
FlipbookBlendFrames `ParticleEmitter.FlipbookBlendFrames: boolean`	Determines whether the flipbook frames are blended between.
FlipbookFramerate `ParticleEmitter.FlipbookFramerate: NumberRange`	Determines how fast the flipbook texture animates in frames per second.
FlipbookIncompatible `ParticleEmitter.FlipbookIncompatible: string`	The error message to display if the Class.ParticleEmitter.Texture\|Texture is incompatible for a flipbook.
FlipbookLayout `ParticleEmitter.FlipbookLayout: ParticleFlipbookLayout`	Determines the layout of the flipbook texture. Must be None, Grid2x2, Grid4x4, Grid8x8 or Custom.
FlipbookMode `ParticleEmitter.FlipbookMode: ParticleFlipbookMode`	Determines the type of the flipbook animation. Must be Loop, OneShot, PingPong, or Random.
FlipbookSizeX `ParticleEmitter.FlipbookSizeX: int`	Defines the number of horizontal frames in a custom flipbook layout.
FlipbookSizeY `ParticleEmitter.FlipbookSizeY: int`	Defines the number of vertical frames in a custom flipbook layout.
FlipbookStartRandom `ParticleEmitter.FlipbookStartRandom: boolean`	Determines whether the animation starts at a random frame chosen per particle instead of always starting at frame zero.
Lifetime `ParticleEmitter.Lifetime: NumberRange`	粒子が消えるまでの時間。Defines a random range of ages for newly emitted particles.
LightEmission `ParticleEmitter.LightEmission: float`	Determines how much particles' colors are blended with the colors behind them.
LightInfluence `ParticleEmitter.LightInfluence: float`	Determines how much particles are influenced by the environmental light.
LockedToPart `ParticleEmitter.LockedToPart: boolean`	Determines whether the particles rigidly move with the part they're being emitted from.
Orientation `ParticleEmitter.Orientation: ParticleOrientation`	Specifies how to orient particles.
Rate `ParticleEmitter.Rate: float`	1秒間に出す粒子の数。Determines the number of particles emitted per second.
Rotation `ParticleEmitter.Rotation: NumberRange`	Determines the range of rotations in degrees for newly emitted particles.
RotSpeed `ParticleEmitter.RotSpeed: NumberRange`	Determines the range of angular speeds of emitted particles, measured in degrees per second.
Shape `ParticleEmitter.Shape: ParticleEmitterShape`	Sets the shape of the emitter to either a box, sphere, cylinder, or disc.
ShapeInOut `ParticleEmitter.ShapeInOut: ParticleEmitterShapeInOut`	Sets whether particles emit outward only, inward only, or in both directions.
ShapePartial `ParticleEmitter.ShapePartial: float`	Influences particle emission from cylinder, disc, sphere, and box shapes.
ShapeStyle `ParticleEmitter.ShapeStyle: ParticleEmitterShapeStyle`	Sets particle emission to either volumetric or surface-only emission.
Size `ParticleEmitter.Size: NumberSequence`	Determines the world size over individual particles' lifetimes.
Speed `ParticleEmitter.Speed: NumberRange`	Determines a random range of velocities (minimum to maximum) at which new particles will emit, measured in studs per second.
SpreadAngle `ParticleEmitter.SpreadAngle: Vector2`	Determines the angles at which particles may be randomly emit, measured in degrees.
Squash `ParticleEmitter.Squash: NumberSequence`	Allows for non-uniform scaling of particles, curve-controlled over their lifetime.
Texture `ParticleEmitter.Texture: ContentId`	Determines the image rendered on particles.
TextureContent `ParticleEmitter.TextureContent: Content`	The image rendered on particles. Supports asset URIs.
TimeScale `ParticleEmitter.TimeScale: float`	Value between 0 and 1 that controls the speed of the particle effect.
Transparency `ParticleEmitter.Transparency: NumberSequence`	Determines the transparency of particles over their individual lifetimes.
VelocityInheritance `ParticleEmitter.VelocityInheritance: float`	Determines how much of the parent's velocity is inherited by particles when emitted.
WindAffectsDrag `ParticleEmitter.WindAffectsDrag: boolean`	Whether emitted particles follow the Workspace.GlobalWind vector.
ZOffset `ParticleEmitter.ZOffset: float`	Determines the forward-backward render position of particles; used to control what particles render on top/bottom.
