Member Function Documentation

void DiscardPending

(

)

Discards all pending updates caused by moved or modified navmesh cuts.

void FindGraph ( )

private

void ForceUpdate

(

)

Checks all NavmeshCut instances and updates graphs if needed.

Note

This schedules updates for all necessary tiles to happen as soon as possible. The pathfinding threads will continue to calculate the paths that they were calculating when this function was called and then they will be paused and the graph updates will be carried out (this may be several frames into the future and the graph updates themselves may take several frames to complete). If you want to force all navmesh cutting to be completed in a single frame call this method and immediately after call AstarPath.FlushWorkItems.

void HandleOnDisableCallback ( NavmeshClipper  obj )

private

Called when a NavmeshCut or NavmeshAdd is disabled.

void HandleOnEnableCallback ( NavmeshClipper  obj )

private

Called when a NavmeshCut or NavmeshAdd is enabled.

void OnDisable ( )

private

void OnEnable ( )

private

void OnRecalculatedTiles ( NavmeshTile[]  tiles )

private

Called when some recast graph tiles have been completely recalculated.

void Start ( )

private

void Update ( )

private

Update is called once per frame.

void UseSpecifiedHandler

(

TileHandler

newHandler

)

Use the specified handler, will create one at start if not called.

Member Data Documentation

TileHandler handler

private

float lastUpdateTime = float.NegativeInfinity

private

float updateInterval

How often to check if an update needs to be done (real seconds between checks).

For very large worlds with lots of NavmeshCut objects, it might be a performance penalty to do this check every frame. If you think this is a performance penalty, increase this number to check less often.

For almost all games, this can be kept at 0.

If negative, no updates will be done. They must be manually triggered using ForceUpdate
