✨ 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.

🧑‍💻API Source

The methods, properties and events descriptions from this page are defined in our GitHub API Repository!

---

tip

Both Cascade and Niagara Particle Systems are supported!

🎒 Examples

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

🛠 Constructors

Default Constructor

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

Type	Name	Default	Description
Vector	location
Rotator	rotation
Particle Reference	asset
boolean	auto_destroy	true
boolean	auto_activate	true

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.
