Spawning an Actor

This page explains how to create entities directly using SpawnActor, the low-level Unreal Engine method for spawning actors into the world.

/// info If you want to use simplified constructors like HVehicle() or Billboard(), refer to the API Reference instead. ///

/// tip This constructor will produce an Actor so it inherits all functions from Actor ///

Parameters

class: UClass — The actor class to spawn (usually a Blueprint class)
transform: FTransform — Location, rotation, and scale for the new actor
collisionHandling: ESpawnActorCollisionHandlingMethod — Optional (default: AlwaysSpawn)
owner: AActor — Optional actor that owns the new entity
instigator: APawn — Optional instigator (e.g., the pawn that created the entity)
tag: string — Optional gameplay tag (used internally for classification or filtering)

/// warning When loading Blueprint classes with LoadClass(), always include the _C suffix at the end of the asset path. This refers to the generated class object, not the Blueprint asset itself. ///

Spawn a Vehicle
-- Blueprint Class
local ProjClass = LoadClass("/Game/Vehicles/BP_Car.BP_Car_C")

-- Location
local Transform = Transform()
Transform.Translation = Vector(1540, 6852, 1000) -- X, Y, Z
Transform.Rotation = Rotator(0, 90, 0):ToQuat() -- Pitch, Yaw, Roll (degrees, not radians)
Transform.Scale3D = Vector(2, 2, 2) -- Uniform scale (x2 size)

-- Constructor (HWorld globally available)
local Car = HWorld:SpawnActor(
    ProjClass,
    Transform,
    ESpawnActorCollisionHandlingMethod.AlwaysSpawn, -- (Optional)
    self, -- Owner (Optional)
    self.Instigator, -- Instigator (Optional)
    "Vehicle.BP_Car_C" -- Spawn tag (Optional)
)

if not Car then
    print("Failed to spawn vehicle!")
    return
end
