Member Function Documentation

◆ CalculateWallForce()

Vector2 CalculateWallForce	(	Vector2	position,
		float	elevation,
		Vector2	directionToTarget
	)

private

◆ ClampToNavmesh()

override Vector3 ClampToNavmesh	(	Vector3	position,
		out bool	positionChanged
	)

protectedvirtual

Constrains the character's position to lie on the navmesh.

Not all movement scripts have support for this.

Parameters

position	Current position of the character.
positionChanged	True if the character's position was modified by this method.

Returns: New position of the character that has been clamped to the navmesh.

Reimplemented from AIBase.

◆ FinalMovement()

void FinalMovement	(	Vector3	position3D,
		float	deltaTime,
		float	distanceToEndOfPath,
		float	slowdownFactor,
		out Vector3	nextPosition,
		out Quaternion	nextRotation
	)

private

◆ MovementUpdateInternal()

override void MovementUpdateInternal	(	float	deltaTime,
		out Vector3	nextPosition,
		out Quaternion	nextRotation
	)

protectedvirtual

Called during either Update or FixedUpdate depending on if rigidbodies are used for movement or not.

Implements AIBase.

◆ NextPart()

void NextPart ( )

protected

Declare that the AI has completely traversed the current part.

This will skip to the next part, or call OnTargetReached if this was the last part

◆ OnDisable()

override void OnDisable ( )

protectedvirtual

Called when the component is disabled.

Reimplemented from AIBase.

◆ OnDrawGizmos()

override void OnDrawGizmos ( )

protectedvirtual

Reimplemented from AIBase.

◆ OnPathComplete()

override void OnPathComplete ( Path newPath )

protectedvirtual

Called when a requested path has been calculated.

Implements AIBase.

◆ OnTargetReached()

virtual void OnTargetReached ( )

protectedvirtual

Called when the end of the path is reached.

◆ OnUpgradeSerializedData()

override int OnUpgradeSerializedData	(	int	version,
		bool	unityThread
	)

protectedvirtual

Handle serialization backwards compatibility.

Reimplemented from AIBase.

◆ SearchPath()

override void SearchPath ( )

virtual

Recalculate the current path.

You can for example use this if you want very quick reaction times when you have changed the destination so that the agent does not have to wait until the next automatic path recalculation (see canSearch).

If there is an ongoing path calculation, it will be canceled, so make sure you leave time for the paths to get calculated before calling this function again. A canceled path will show up in the log with the message "Canceled by script" (see #Seeker.CancelCurrentPathRequest()).

If no destination has been set yet then nothing will be done.

Note: The path result may not become available until after a few frames. During the calculation time the pathPending property will return true.

See also: pathPending

Reimplemented from AIBase.

◆ Teleport()

override void Teleport	(	Vector3	newPosition,
		bool	clearPath = `true`
	)

virtual

Instantly move the agent to a new position.

This will trigger a path recalculation (if clearPath is true, which is the default) so if you want to teleport the agent and change its destination it is recommended that you set the destination before calling this method.

The current path will be cleared by default.

See also: Works similarly to Unity's NavmeshAgent.Warp.; SearchPath

When setting transform.position directly the agent will be clamped to the part of the navmesh it can reach, so it may not end up where you wanted it to. This ensures that the agent can move to any part of the navmesh.

Reimplemented from AIBase.

◆ TraverseFunnel()

void TraverseFunnel	(	RichFunnel	fn,
		float	deltaTime,
		out Vector3	nextPosition,
		out Quaternion	nextRotation
	)

private

◆ TraverseOffMeshLinkFallback()

IEnumerator TraverseOffMeshLinkFallback ( RichSpecial link )

protected

Fallback for traversing off-mesh links in case onTraverseOffMeshLink is not set.

This will do a simple linear interpolation along the link.

◆ TraverseSpecial()

virtual IEnumerator TraverseSpecial ( RichSpecial link )

protectedvirtual

Traverses an off-mesh link.

◆ UpdatePath()

void UpdatePath ( )

Force recalculation of the current path.

If there is an ongoing path calculation, it will be canceled (so make sure you leave time for the paths to get calculated before calling this function again).

Deprecated:: Use SearchPath instead

◆ UpdateTarget()

virtual Vector3 UpdateTarget ( RichFunnel fn )

protectedvirtual

Member Data Documentation

◆ acceleration

float acceleration = 5

Max acceleration of the agent.

In world units per second per second.

◆ animCompatibility

Animation animCompatibility

private

◆ delayUpdatePath

bool delayUpdatePath

protected

◆ distanceToSteeringTarget

float distanceToSteeringTarget = float.PositiveInfinity

protected

Distance to steeringTarget in the movement plane.

◆ endReachedDistance

float endReachedDistance = 0.01f

Max distance to the endpoint to consider it reached.

See also: reachedEndOfPath; OnTargetReached

◆ funnelSimplification

bool funnelSimplification = false

Use funnel simplification.

On tiled navmesh maps, but sometimes on normal ones as well, it can be good to simplify the funnel as a post-processing step to make the paths straighter.

This has a moderate performance impact during frames when a path calculation is completed.

The RichAI script uses its own internal funnel algorithm, so you never need to attach the FunnelModifier component.

◆ GizmoColorPath

readonly Color GizmoColorPath = new Color(8.0f/255, 78.0f/255, 194.0f/255)

staticprotected

◆ lastCorner

bool lastCorner

protected

◆ nextCorners

readonly List<Vector3> nextCorners = new List<Vector3>()

protected

◆ onTraverseOffMeshLink

System.Func<RichSpecial, IEnumerator> onTraverseOffMeshLink

Called when the agent starts to traverse an off-mesh link.

Register to this callback to handle off-mesh links in a custom way.

If this event is set to null then the agent will fall back to traversing off-mesh links using a very simple linear interpolation.

    void OnEnable () {
        ai = GetComponent<RichAI>();
        if (ai != null) ai.onTraverseOffMeshLink += TraverseOffMeshLink;
    }
    void OnDisable () {
        if (ai != null) ai.onTraverseOffMeshLink -= TraverseOffMeshLink;
    }
    IEnumerator TraverseOffMeshLink (RichSpecial link) {
        // Traverse the link over 1 second
        float startTime = Time.time;
        while (Time.time < startTime + 1) {
            transform.position = Vector3.Lerp(link.first.position, link.second.position, Time.time - startTime);
            yield return null;
        }
        transform.position = link.second.position;
    }

◆ richPath

readonly RichPath richPath = new RichPath()

protected

Holds the current path that this agent is following.

◆ rotationSpeed

float rotationSpeed = 360

Max rotation speed of the agent.

In degrees per second.

◆ slowdownTime

float slowdownTime = 0.5f

How long before reaching the end of the path to start to slow down.

A lower value will make the agent stop more abruptly.

Note: The agent may require more time to slow down if its maximum acceleration is not high enough.

If set to zero the agent will not even attempt to slow down. This can be useful if the target point is not a point you want the agent to stop at but it might for example be the player and you want the AI to slam into the player.

Note: A value of zero will behave differently from a small but non-zero value (such as 0.0001). When it is non-zero the agent will still respect its acceleration when determining if it needs to slow down, but if it is zero it will disable that check. This is useful if the destination is not a point where you want the agent to stop.

◆ slowWhenNotFacingTarget

bool slowWhenNotFacingTarget = true

Slow down when not facing the target direction.

Incurs at a small performance overhead.

◆ wallBuffer

readonly List<Vector3> wallBuffer = new List<Vector3>()

protected

◆ wallDist

float wallDist = 1

Walls within this range will be used for avoidance.

Setting this to zero disables wall avoidance and may improve performance slightly

See also: wallForce

◆ wallForce

float wallForce = 3

Force to avoid walls with.

The agent will try to steer away from walls slightly.

See also: wallDist

Property Documentation

◆ anim

Animation anim

getset

Anim for off-mesh links.

Deprecated:: Use the onTraverseOffMeshLink event or the ... component instead. Setting this value will add a ... component

◆ ApproachingPartEndpoint

bool ApproachingPartEndpoint

get

Deprecated:: Use approachingPartEndpoint (lowercase 'a') instead

◆ approachingPartEndpoint

bool approachingPartEndpoint

get

True if approaching the last waypoint in the current part of the path.

Path parts are separated by off-mesh links.

See also: approachingPathEndpoint

◆ ApproachingPathEndpoint

bool ApproachingPathEndpoint

get

Deprecated:: Use approachingPathEndpoint (lowercase 'a') instead

◆ approachingPathEndpoint

bool approachingPathEndpoint

get

True if approaching the last waypoint of all parts in the current path.

Path parts are separated by off-mesh links.

See also: approachingPartEndpoint

◆ canMove

bool IAstarAI. canMove

getsetprivate

Enables or disables movement completely.

If you want the agent to stand still, but still react to local avoidance and use gravity: use isStopped instead.

This is also useful if you want to have full control over when the movement calculations run. Take a look at MovementUpdate

See also: canSearch; isStopped

◆ canSearch

bool IAstarAI. canSearch

getsetprivate

Enables or disables recalculating the path at regular intervals.

Setting this to false does not stop any active path requests from being calculated or stop it from continuing to follow the current path.

Note that this only disables automatic path recalculations. If you call the SearchPath() method a path will still be calculated.

See also: canMove; isStopped

◆ DistanceToNextWaypoint

float DistanceToNextWaypoint

get

Deprecated:: Use Vector3.Distance(transform.position, ai.steeringTarget) instead.

◆ hasPath

bool hasPath

get

True if this agent currently has a path that it follows.

◆ height

float IAstarAI. height

getsetprivate

Radius of the agent in world units.

This is visualized in the scene view as a yellow cylinder around the character.

Note: The Pathfinding.AILerp script doesn't really have any use of knowing the radius or the height of the character, so this property will always return 0 in that script.

◆ maxSpeed

float IAstarAI. maxSpeed

getsetprivate

Max speed in world units per second.

◆ NextWaypoint

Vector3 NextWaypoint

get

Waypoint that the agent is moving towards.

This is either a corner in the path or the end of the path.

Deprecated:: Use steeringTarget instead.

◆ PathPending

bool PathPending

get

True if a path to the target is currently being calculated.

Deprecated:: Use pathPending instead (lowercase 'p').

◆ pathPending

bool pathPending

get

True if a path is currently being calculated.

◆ position

Vector3 IAstarAI. position

getprivate

Position of the agent.

In world space.

See also: rotation

◆ radius

float IAstarAI. radius

getsetprivate

Height of the agent in world units.

This is visualized in the scene view as a yellow cylinder around the character.

This value is currently only used if an RVOController is attached to the same GameObject, otherwise it is only used for drawing nice gizmos in the scene view. However since the height value is used for some things, the radius field is always visible for consistency and easier visualization of the character. That said, it may be used for something in a future release.

Note: The Pathfinding.AILerp script doesn't really have any use of knowing the radius or the height of the character, so this property will always return 0 in that script.

◆ reachedDestination

bool reachedDestination

get

True if the ai has reached the destination.

This is a best effort calculation to see if the destination has been reached. For the AIPath/RichAI scripts, this is when the character is within endReachedDistance world units from the destination. For the AILerp script it is when the character is at the destination (±a very small margin).

This value will be updated immediately when the destination is changed (in contrast to reachedEndOfPath), however since path requests are asynchronous it will use an approximation until it sees the real path result. What this property does is to check the distance to the end of the current path, and add to that the distance from the end of the path to the destination (i.e. is assumes it is possible to move in a straight line between the end of the current path to the destination) and then checks if that total distance is less than endReachedDistance. This property is therefore only a best effort, but it will work well for almost all use cases.

Furthermore it will not report that the destination is reached if the destination is above the head of the character or more than half the height of the character below its feet (so if you have a multilevel building, it is important that you configure the height of the character correctly).

The cases which could be problematic are if an agent is standing next to a very thin wall and the destination suddenly changes to the other side of that thin wall. During the time that it takes for the path to be calculated the agent may see itself as alredy having reached the destination because the destination only moved a very small distance (the wall was thin), even though it may actually be quite a long way around the wall to the other side.

In contrast to reachedEndOfPath, this property is immediately updated when the destination is changed.

See also: #AIPath.endReachedDistance; remainingDistance; reachedEndOfPath

◆ reachedEndOfPath

bool reachedEndOfPath

get

True if the agent has reached the end of the current path.

Note that setting the destination does not immediately update the path, nor is there any guarantee that the AI will actually be able to reach the destination that you set. The AI will try to get as close as possible. Often you want to use reachedDestination instead which is easier to work with.

It is very hard to provide a method for detecting if the AI has reached the destination that works across all different games because the destination may not even lie on the navmesh and how that is handled differs from game to game (see also the code snippet in the docs for destination).

See also: remainingDistance; reachedDestination

◆ remainingDistance

float remainingDistance

get

Remaining distance along the current path to the end of the path.

For the RichAI movement script this may not always be precisely known, especially when far away from the destination. In those cases an approximate distance will be returned.

If the agent does not currently have a path, then positive infinity will be returned.

Note: This is the distance to the end of the path, which may or may not be at the destination. If the character cannot reach the destination it will try to move as close as possible to it.

Warning: Since path requests are asynchronous, there is a small delay between a path request being sent and this value being updated with the new calculated path.

See also: reachedDestination; reachedEndOfPath
