AppSystemCommon Interface

This interface is used to provide a common interface for both AppSystemActivities and AppSystemServices. It provides access to the SystemManager and allows for registering mesh creators.

Signature

interface AppSystemCommon

Functions

getSystemManager ()
Signature 
abstract fun getSystemManager(): SystemManager
Returns
registerMeshCreator ( baseUrl , creator )
Registers a mesh creator for a base URL pattern.
The creator will be invoked for any mesh URI that matches the base URL (scheme + authority + path). Query parameters from the full URI will be passed to the creator for customization.
Example: 
// Register a creator for "mesh://custom/sphere"
registerMeshCreator("mesh://custom/sphere") { entity, uri ->
    val radius = uri.getQueryParameter("radius")?.toFloatOrNull() ?: 1.0f
    val color = uri.getQueryParameter("color") ?: "white"
    createSphere(entity, radius, color)
}
// Later, use with parameters:
Mesh(Uri.parse("mesh://custom/sphere?radius=2.5&color=red"))
Parameters
baseUrl: String
  The base URL to match (e.g., "mesh://myapp/custom"). Query parameters are ignored in matching.
creator: Function2
  Function that takes an Entity and the full URI (including query params), returns a SceneMesh
registerMeshCreator ( meshURL , creator )
Registers a simple mesh creator that doesn't need URI parameters.
This is a convenience method for mesh creators that don't need to read query parameters from the URI. The mesh URL must match exactly.
Example: 
registerMeshCreator("mesh://custom") { entity ->
    SceneMesh.box(-0.5f, -0.5f, -0.5f, 0.5f, 0.5f, 0.5f, material)
}
Signature 
open fun registerMeshCreator(meshURL: String, creator: (entity: Entity) -> SceneMesh)
Parameters
meshURL: String
  The exact mesh URL to match
creator: Function1
  Function that takes an Entity and returns a SceneMesh
unregisterMeshCreator ( baseUrl )
Unregisters a mesh creator for the given base URL.
Signature 
open fun unregisterMeshCreator(baseUrl: String)
Parameters
baseUrl: String
  The base URL that was registered
