This system comes default with Meta Spatial SDK and operates on entities with Mesh components. It uses the MeshManager to load and create meshes from various sources (mesh://, file://, http://, etc.) and attaches them to entities. It also handles cleanup when entities are deleted.

This System is a core part of the rendering pipeline and is registered early in the system execution order to ensure meshes are available for other systems.

Signature

class MeshCreationSystem(val meshManager: MeshManager) : SystemBase

Constructors

MeshCreationSystem ( meshManager )

Signature

constructor(meshManager: MeshManager)

Parameters

meshManager: MeshManager The mesh manager to use for creating the mesh.

Returns

MeshCreationSystem

Properties

meshManager : MeshManager [Get]	Signature val meshManager: MeshManager
systemManager : SystemManager [Get][Set]	The system manager that this system is associated with. Signature lateinit var systemManager: SystemManager

Methods

associateSystemManager ( systemManager )	Associates this system with a system manager, used in the Spatial SDK. Signature fun associateSystemManager(systemManager: SystemManager) Parameters `systemManager: SystemManager` The system manager to associate with.
delete ( entity )	System should do any housekeeping based on MeshCreationSystem.delete being removed from the scene Signature open override fun delete(entity: Entity) Parameters `entity: Entity`
destroy ()	System should clean up any and all resources for shutdown Signature open override fun destroy()
equals ( other )	Checks if this system is equal to another object. Signature open operator override fun equals(other: Any?): Boolean Parameters `other: Any?` The object to compare with. Returns `Boolean` True if this system is equal to the other object, false otherwise.
execute ()	System should perform all the operations based on relevant entities. Signature open override fun execute()
getDependencies ()	Returns the dependencies of this system. Signature open fun getDependencies(): SystemDependencies? Returns `SystemDependencies?` The dependencies of this system, or null if there are no dependencies.
getScene ()	Returns the scene that this system is associated with. Signature fun getScene(): Scene Returns `Scene` The scene that this system is associated with.
hashCode ()	Returns the hash code of this system. Signature open override fun hashCode(): Int Returns `Int` The hash code of this system.
preloadMesh ( mesh , defaultShaderOverride , defaultSceneOverride )	Preloads a mesh without attaching it to any entity for faster loading later. This method loads and caches a mesh from the specified URI so that when it's later assigned to an entity via the Mesh component, it will be available immediately. This is useful for performance optimization when you know certain meshes will be needed soon. Signature fun preloadMesh(mesh: Uri, defaultShaderOverride: String = "", defaultSceneOverride: Int = 0) Parameters `mesh: Uri` The URI of the mesh to preload `defaultShaderOverride: String` Optional shader override to use when loading the mesh `defaultSceneOverride: Int` Optional scene index override to use when loading the mesh
