Recast Graph and Multiple Scenes - Need for Filter API

1

Is there a way to tell a graph or the scan function to limit its scan to a single scene? I have multiple scenes in my game (which are mutually exclusive) and RecastGraph.Scan() is referencing game objects in the other scenes.

A CollectionSettings.Scene? property may work as an effective filter. The existing CollectionSettings.PhysicsScene? property may be shared across scenes.

I used to have two separate physics scenes – one for planetside gameplay and one for stellar gameplay. But by sharing a single physics scene and using layers to separate physics interactions, I gain approximately 0.7 MS CPU time per frame, which is significant.

But now A*Pathfinding is accessing colliders in other scenes which share similar tags.

Thanks,

Shaun

So these scenes do not overlap at all? None of the objects in one scene overlap another scene’s graph?

That’s right, no overlap. One is planetside and the other is in space. The ‘sharing’ of coordinate space is to achieve floating point precision. Both playable areas are centered about the origin.

If there aren’t any overlapping graphs would you be able to take advantage of scanning only the area in the graph you’re wanting to scan, with say, GraphUpdateScene?
