Syntax

class UParticleLODLevel : public UObject

Variables

  Type Name Description
Public variable uint32: 1 bEnabled True if the LOD level is enabled, meaning it should be updated and rendered.
Public variable uint32: 1 ConvertedModules  
Public variable TObjectPtr< class UParticleModuleEventGenerator > EventGenerator The optional EventGenerator module.
Public variable TArray< TObjectPtr< class UParticleModuleEventReceiverBase > > EventReceiverModules Event receiver modules only!
Public variable int32 Level The index value of the LOD level
Public variable TArray< TObjectPtr< class UParticleModule > > Modules An array of particle modules that contain the adjusted data for the LOD level
Public variable TArray< TObjectPtr< class UParticleModuleOrbit > > OrbitModules OrbitModules These are used to do offsets of the sprite from the particle location.
Public variable int32 PeakActiveParticles  
Public variable TObjectPtr< class UParticleModuleRequired > RequiredModule The required module for this LOD level
Public variable TArray< TObjectPtr< class UParticleModuleSpawnBase > > SpawningModules SpawningModules - These are called to determine how many particles to spawn.
Public variable TObjectPtr< class UParticleModuleSpawn > SpawnModule The SpawnRate/Burst module - required by all emitters.
Public variable TArray< TObjectPtr< class UParticleModule > > SpawnModules SpawnModules - These are called when particles are spawned.
Public variable TObjectPtr< class UParticleModuleTypeDataBase > TypeDataModule Module used for emitter type "extension".
Public variable TArray< TObjectPtr< class UParticleModule > > UpdateModules UpdateModules - These are called when particles are updated.
