Caching multiple Recast Graphs

General Recast graph
1
  • A* version: [5.3.4]
  • Unity version: [2022.3.55]

I have a large game scene divided into Sectors/Regions. I have a specific Recast Graph for each Sector (NPC’s do not need to traverse between them and stay in their assigned Sector).

I have created a Cache for each Recast Graph and I also assign the appropriate graph to each NPC via their Traversable Graph in their FollowerEntity.

At runtime though. ONLY the CachedRecastGraph assigned in the Settings/Load component of A* is used and thus no pathfinding for any other NPC’s in any other Sector.

Is there a way to ensure all CachedRecastGraphs are used? Or does this have to be left so scan each Recast Graph at runtime.

Thank you!

You can use some code on Start/Awake to apply a cached file to each different graph individually:

Thank you for the reply. I might be missing something…but I see how to do so with Loading/Saving/Caching graph data to 1 Recast graph, but not how to have Each Individual Recast Graph load it’s respective CachedGraph data

(Sorry I though I replied to the wrong post)

So if you want to have like, different areas randomly spawn and have their graphs loaded, you’ll want to use something like this:

void AddGraphsFromFile(TextAsset graphFile){
    AstarPath.active.data.DeserializeGraphsAdditive(graphFile.bytes);
}

You can then make each graph a TextAsset and load it additively, rather than from the cache. Each graph file can also hold multiple graphs and add them all.
