Class SceneNetworkGraph

Namespace: mobisim.Scenes.SNGraph

A directed node graph for managing scene-based flows. This graph facilitates linear or branched scene progression, and provides utility methods to traverse and retrieve scene references during runtime.

public class SceneNetworkGraph : NodeGraph

Inheritance

NodeGraph→SceneNetworkGraph

Methods

GetCurrentScene()

Returns the current scene referenced by the current node.

public SceneAssetReference GetCurrentScene()

Returns

SceneAssetReference — The current scene reference, or null if unavailable.

GetNextScene()

Retrieves the next available scene by traversing the graph.

public SceneAssetReference GetNextScene()

Returns

SceneAssetReference — The next scene reference if found; otherwise, null if the end of the graph is reached or no scene is available.

GetStartNode()

Finds and returns the start node in the graph.

public Node GetStartNode()

Returns

Node — The start node, or null if it not exist.

HasReachedTheEnd()

Checks whether the graph has reached an end node.

public bool HasReachedTheEnd()

Returns

bool — true if the current node is an end node; otherwise, false.

OnAfterDeserialize()

Callback that reset pointer current to null after deserialize.

public void OnAfterDeserialize()

OnBeforeSerialize()

Callback that reset pointer current to null before serialize.

public void OnBeforeSerialize()

TryGetNextScene(out SceneAssetReference, out int)

Attempts to traverse the graph from the current node to the next available SceneNode. If successful, returns its associated scene asset reference and the corresponding scene index.

public bool TryGetNextScene(out SceneAssetReference nextScene, out int index)

Parameters

Name	Type	Description
nextScene	SceneAssetReference	The next available scene asset reference.
index	int	The index of the retrieved scene.

Returns

bool — true if a scene is found; otherwise, false.

Remarks

This method traverses the graph by moving the current node pointer according to the following rules:

• Traverse only nodes that implement ITraversableNode, updating the current pointer at each step.
• If current node is null, start at StartNode and update pointer.
• Return scene reference when a SceneNode is found.
• If current node is an EndNode or no next node to traverse, return false and null scene.
