Particle

Class to spawn Particle Systems used to create effects in the world.


💂Authority
This class can be spawned on both 🟧 Client and 🟦 Server side (if you spawn it on client, it won't be synchronized with other players).
👪Inheritance
This class shares methods and events from Base Entity, Base Actor.

tip

Both Cascade and Niagara Particle Systems are supported!

Examples

local my_particle = Particle(
Vector(-200, 100, 100),
Rotator(0, 0, 0),
"helix::P_Explosion",
true, -- Auto Destroy?
true -- Auto Activate?
)

Constructors

Default Constructor

local my_particle = Particle(location, rotation, asset, auto_destroy?, auto_activate?)
TypeNameDefaultDescription

booleanauto_activatetrue
Note

auto_destroy means the Entity will be immediately destroyed after spawned, losing references to the Particle System spawned in-game. So if the Particle System itself loops indefinitely, it will keep playing until the Player reconnects.
