The Fire class is of several particle-emitting classes. Like other particle emitters of its kind, Fire objects emit particles when parented to a BasePart (such as a Part) or an Attachment within such a BasePart. Compared to the ParticleEmitter class, Fire lacks many different customization properties and special methods, such as ParticleEmitter/Lifetime or ParticleEmitter/Emit. It is useful to create a quick special effect in a pinch; for more detailed work it is preferable to use a ParticleEmitter instead.

Fire objects do not emit any light on their own. To help create a cohesive environment around a burning object in your world, try adding a PointLight with a PointLight/Color set to orange. This will make your fire look more realistic.

When Fire/Enabled is toggled off, particles emit by this object will continue to render until their lifetime expires. When a Fire object’s Instance/Parent is set to nil (and/or Instance/Destroyed), all particles will instantly disappear. If this effect is not desired, try hiding the parent object at a far away position, then removing the Fire after a few seconds using Debris to give the last particles a chance to expire. This object does not have a ParticleEmitter/Clear method, but it is possible to set the Instance/Parent to nil and back to the exact same object for the same effect.

Fire particles are only emit from the center of BasePart to which they are parented. The particles are emit toward the top (+Y) direction; however, a negative Fire/Heat may be used to emit in the bottom (-Y) direction. Parenting a Fire object to an Attachment instead allows customization of the particles’ start position and emission direction.

Fire object consist of two emitters. Each are affected differently by Fire/Size, Fire/Heat, Fire/Color and Fire/SecondaryColor. The particles emit from the smaller, secondary emitter have a significantly longer lifetime (and rise farther) than those emit by the primary emitter.

Unlike actual flames, Fire objects on Roblox do not spread on their own. If you notice this behavior in your game, it is happening because a Script is spreading fire.
