Function Seeker.StartPath

Path StartPath (

Path

p

The path to start calculating

)

Queue a path to be calculated.

This overload takes no callback parameter. Instead, it is expected that you poll the path for completion, or block until it is completed.

However, Path.IsDone should not be used with the Seeker component. This is because while the path itself may be calculated, the Seeker may not have had time to run post processing modifiers on the path yet.

Path StartPath (

Path	p	The path to start calculating
OnPathDelegate	callback	The function to call when the path has been calculated. If you don't want a callback (e.g. if you instead poll path.IsDone or use a similar method) you can set this to null.

)

Queue a path to be calculated.

The callback will be called when the path has been calculated (which may be several frames into the future). The callback will not be called if a new path request is started before this path request has been calculated.

Path StartPath (

Path	p	The path to start calculating
OnPathDelegate	callback	The function to call when the path has been calculated. If you don't want a callback (e.g. if you instead poll path.IsDone or use a similar method) you can set this to null.
GraphMask	graphMask	Mask used to specify which graphs should be searched for close nodes. See GraphMask. This will override the graphMask on this Seeker.

)

Queue a path to be calculated.

The callback will be called when the path has been calculated (which may be several frames into the future). The callback will not be called if a new path request is started before this path request has been calculated.

Path StartPath (

Vector3	start	The start point of the path
Vector3	end	The end point of the path
OnPathDelegate	callback	The function to call when the path has been calculated. If you don't want a callback (e.g. if you instead poll path.IsDone or use a similar method) you can set this to null.

)

Queue a path to be calculated.

The callback will be called when the path has been calculated (which may be several frames into the future). Callback will not be called if the path is canceled (e.g when a new path is requested before the previous one has completed)

void Start () {
// Get the seeker component attached to this GameObject
var seeker = GetComponent<Seeker>();

// Schedule a new path request from the current position to a position 10 units forward.
// When the path has been calculated, the OnPathComplete method will be called, unless it was canceled by another path request
seeker.StartPath(transform.position, transform.position + Vector3.forward * 10, OnPathComplete);

// Note that the path is NOT calculated at this point
// It has just been queued for calculation
}

void OnPathComplete (Path path) {
// The path is now calculated!

if (path.error) {
Debug.LogError("Path failed: " + path.errorLog);
return;
}

// Cast the path to the path type we were using
var abPath = path as ABPath;

// Draw the path in the scene view for 10 seconds
for (int i = 0; i < abPath.vectorPath.Count - 1; i++) {
Debug.DrawLine(abPath.vectorPath[i], abPath.vectorPath[i+1], Color.red, 10);
}
}


Path StartPath (

Vector3	start	The start point of the path
Vector3	end	The end point of the path
OnPathDelegate	callback	The function to call when the path has been calculated. If you don't want a callback (e.g. if you instead poll path.IsDone or use a similar method) you can set this to null.
GraphMask	graphMask	Mask used to specify which graphs should be searched for close nodes. See Pathfinding.NNConstraint.graphMask. This will override the graphMask on this Seeker.

)

Queue a path to be calculated.

The callback will be called when the path has been calculated (which may be several frames into the future). Callback will not be called if the path is canceled (e.g when a new path is requested before the previous one has completed)

// Schedule a path search that will only start searching the graphs with index 0 and 3
seeker.StartPath(startPoint, endPoint, null, 1 << 0 | 1 << 3);


Path StartPath (

Vector3	start	The start point of the path
Vector3	end	The end point of the path

)

Queue a path to be calculated.

Since this method does not take a callback parameter, you should set the pathCallback field before calling this method.

void Start () {
// Get the seeker component attached to this GameObject
var seeker = GetComponent<Seeker>();

// Schedule a new path request from the current position to a position 10 units forward.
// When the path has been calculated, the OnPathComplete method will be called, unless it was canceled by another path request
seeker.StartPath(transform.position, transform.position + Vector3.forward * 10, OnPathComplete);

// Note that the path is NOT calculated at this point
// It has just been queued for calculation
}

void OnPathComplete (Path path) {
// The path is now calculated!

if (path.error) {
Debug.LogError("Path failed: " + path.errorLog);
return;
}

// Cast the path to the path type we were using
var abPath = path as ABPath;

// Draw the path in the scene view for 10 seconds
for (int i = 0; i < abPath.vectorPath.Count - 1; i++) {
Debug.DrawLine(abPath.vectorPath[i], abPath.vectorPath[i+1], Color.red, 10);
}
