Class AILerp Extends VersionedMonoBehaviour, IAstarAI

void FinalizeMovement (

Vector3	nextPosition
Quaternion	nextRotation

)

Move the agent.

To be called as the last step when you are handling movement manually.

The movement will be clamped to the navmesh if applicable (this is done for the RichAI movement script).

void ForceSearchPath ()

Requests a path to the target.

Bypasses 'is-it-a-good-time-to-request-a-path' checks.

Vector3 GetFeetPosition ()

void MovementUpdate (

float	deltaTime	time to simulate movement for. Usually set to Time.deltaTime.
out Vector3	nextPosition	the position that the agent wants to move to during this frame.
out Quaternion	nextRotation	the rotation that the agent wants to rotate to during this frame.

)

Calculate how the character wants to move during this frame.

Note that this does not actually move the character. You need to call FinalizeMovement for that. This is called automatically unless canMove is false.

To handle movement yourself you can disable canMove and call this method manually. This code will replicate the normal behavior of the component: void Update () {
ai.canMove = false;
Vector3 nextPosition;
Quaternion nextRotation;
ai.MovementUpdate(Time.deltaTime, out nextPosition, out nextRotation);
// Modify nextPosition and nextRotation in any way you wish
ai.FinalizeMovement(nextPosition, nextRotation);
}


void OnDisable ()

void OnPathComplete (

Path

_p

)

Called when a requested path has finished calculation.

A path is first requested by SearchPath, it is then calculated, probably in the same or the next frame. Finally it is returned to the seeker which forwards it to this function.

void OnTargetReached ()

The end of the path has been reached.

If you want custom logic for when the AI has reached it's destination add it here. You can also create a new script which inherits from this one and override the function in that script.

void SearchPath ()

Requests a path to the target.

void Teleport (

Vector3	newPosition
bool	clearPath

)

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.

bool canMove = true

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

bool canSearch = true

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.

Vector3 destination

bool enableRotation = true

If true, the AI will rotate to face the movement direction.

bool hasPath

bool interpolatePathSwitches = true

If true, some interpolation will be done when a new path has been calculated.

This is used to avoid short distance teleportation.

bool isStopped

Gets or sets if the agent should stop moving.

If this is set to true the agent will immediately start to slow down as quickly as it can to come to a full stop. The agent will still react to local avoidance and gravity (if applicable), but it will not try to move in any particular direction.

The current path of the agent will not be cleared, so when this is set to false again the agent will continue moving along the previous path.

This is a purely user-controlled parameter, so for example it is not set automatically when the agent stops moving because it has reached the target. Use reachedEndOfPath for that.

If this property is set to true while the agent is traversing an off-mesh link (RichAI script only), then the agent will continue traversing the link and stop once it has completed it.

The steeringTarget property will continue to indicate the point which the agent would move towards if it would not be stopped.

System.Action onSearchPath

Called when the agent recalculates its path.

This is called both for automatic path recalculations (see canSearch) and manual ones (see SearchPath).

bool pathPending

Vector3 position

Position of the agent.

In world space.

bool reachedEndOfPath

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

float remainingDistance

float repathRate = 0.5F

Determines how often it will search for new paths.

If you have fast moving targets or AIs, you might want to set it to a lower value. The value is in seconds between path requests.

Quaternion rotation

Rotation of the agent.

In world space.

bool rotationIn2D = false

If true, rotation will only be done along the Z axis so that the Y axis is the forward direction of the character.

This is useful for 2D games in which one often want to have the Y axis as the forward direction to get sprites and 2D colliders to work properly.

float rotationSpeed = 10

How quickly to rotate.

float speed = 3

Speed in world units.

float switchPathInterpolationSpeed = 5

How quickly to interpolate to the new path.

bool updatePosition = true

Determines if the character's position should be coupled to the Transform's position.

If false then all movement calculations will happen as usual, but the object that this component is attached to will not move instead only the position property will change.

bool updateRotation = true

Determines if the character's rotation should be coupled to the Transform's rotation.

If false then all movement calculations will happen as usual, but the object that this component is attached to will not rotate instead only the rotation property will change.

void Awake ()

Initializes reference variables.

If you override this function you should in most cases call base.Awake () at the start of it.

Vector3 CalculateNextPosition (

out Vector3	direction	The tangent of the segment the AI is currently traversing. Not normalized.
float	deltaTime

)

Calculate the AI's next position (one frame in the future).

bool IAstarAI. canMove

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

bool IAstarAI. canSearch

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.

bool canSearchAgain = true

Only when the previous path has been returned should a search for a new path be done.

void ConfigureNewPath ()

Finds the closest point on the current path and configures the interpolator.

void ConfigurePathSwitchInterpolation ()

Vector3 IAstarAI. desiredVelocity

void Init ()

PathInterpolator interpolator = new PathInterpolator()

float lastRepath = -9999

Time when the last path request was sent.

float IAstarAI. maxSpeed

Max speed in world units per second.

void IAstarAI. Move (

Vector3

deltaPosition

Direction and distance to move the agent in world space.

)

Move the agent.

This is intended for external movement forces such as those applied by wind, conveyor belts, knockbacks etc.

Some movement scripts may ignore this completely (notably the AILerp script) if it does not have any concept of being moved externally.

The agent will not be moved immediately when calling this method. Instead this offset will be stored and then applied the next time the agent runs its movement calculations (which is usually later this frame or the next frame). If you want to move the agent immediately then call: ai.Move(someVector);
ai.FinalizeMovement(ai.position, ai.rotation);


void OnEnable ()

Called when the component is enabled.

int OnUpgradeSerializedData (

int	version
bool	unityThread

)

Handle serialization backwards compatibility.

ABPath path

Current path which is followed.

float pathSwitchInterpolationTime = 0

Time since the path was replaced by a new path.

Vector3 previousMovementDirection

Vector3 previousMovementOrigin

When a new path was returned, the AI was moving along this ray.

Used to smoothly interpolate between the previous movement and the movement along the new path. The speed is equal to movement direction.

Vector3 previousPosition1

Vector3 previousPosition2

IEnumerator RepeatTrySearchPath ()

Tries to search for a path every repathRate seconds.

Seeker seeker

Cached Seeker component.

bool shouldRecalculatePath

True if the path should be automatically recalculated as soon as possible.

Vector3 simulatedPosition

Quaternion simulatedRotation

Quaternion SimulateRotationTowards (

Vector3	direction
float	deltaTime

)

void Start ()

Starts searching for paths.

If you override this function you should in most cases call base.Start () at the start of it.

bool startHasRun = false

Holds if the Start function has been run.

Used to test if coroutines should be started in OnEnable to prevent calculating paths in the awake stage (or rather before start on frame 0).

Vector3 IAstarAI. steeringTarget

Point on the path which the agent is currently moving towards.

This is usually a point a small distance ahead of the agent or the end of the path.

If the agent does not have a path at the moment, then the agent's current position will be returned.

Transform targetCompatibility

Required for serialization backward compatibility.

Transform tr

Cached Transform component.

void Update ()

Vector3 IAstarAI. velocity

Transform target

Target to move towards.

The AI will try to follow/move towards this target. It can be a point on the ground where the player has clicked in an RTS for example, or it can be the player object in a zombie game.

float TrySearchPath ()

Tries to search for a path.

Will search for a new path if there was a sufficient time since the last repath and both canSearchAgain and canSearch are true and there is a target.
