Member Function Documentation

CalculateTargetLaneValueCarla()

static int SnapController.CalculateTargetLaneValueCarla ( Lane  startLane, Lane  endLane  )

inlinestatic

Calculates the target lane value for Carla, given start and end lanes. (NOT IMPLEMENTD)

Parameters

startLane	The starting Lane object.
endLane	The ending Lane object.

Returns

An integer representing the target lane value for Carla.

CheckLaneChange()

bool SnapController.CheckLaneChange ( Lane  startLane, Lane  endLane, AStarWaypoint  startWaypoint, AStarWaypoint  endWaypoint  )

inline

Checks if a lane change is possible between the start and end lanes and waypoints.

Parameters

startLane	The starting Lane.
endLane	The ending Lane.
startWaypoint	The starting AStarWaypoint.
endWaypoint	The ending AStarWaypoint.

Returns

True if a lane change is possible, false otherwise.</returns

FastEuclideanDistance()

static double SnapController.FastEuclideanDistance ( Vector2  a, Vector2  b  )

inlinestatic

Computes the fast Euclidean distance between two Vector2 points.

Parameters

a	A Vector2 representing the first point.
b	A Vector2 representing the second point.

Returns

A double representing the fast Euclidean distance between the two points.

FindWaypoint()

Location SnapController.FindWaypoint ( Vector2  mousePosition )

inline

Finds the nearest waypoint to a given mouse position.

Parameters

mousePosition

The Vector2 representing the mouse position.

Returns

Returns a Location object of the nearest waypoint.

UnityRotToRadians()

static float SnapController.UnityRotToRadians ( float  rotation )

inlinestatic

Converts a Unity rotation value to radians.

Parameters

rotation

A float representing the rotation value in Unity.

Returns

A float representing the rotation value in radians.

Member Data Documentation

int

SnapController.int

Parses a lane ID string and returns the corresponding road ID and lane ID as a tuple.

Parameters

laneIdString

The lane ID string to parse.

Returns

Returns a tuple containing the road ID and lane ID.

Lane

SnapController.Lane

Finds the closest Lane and AStarWaypoint to the given mouse position.

Returns the neighboring lanes of a given Lane.

Parameters

mousePosition

A Vector2 representing the position of the mouse cursor.

Returns

A tuple containing the closest Lane and AStarWaypoint to the given mouse position.</returns

Parameters

l	A Lane object.

Returns

A tuple containing the previous and next lanes of the given Lane.

List< Vector2 >

SnapController.List< Vector2 >

Finds a path between the start and end positions, considering lane changes and optional waypoint ignoring.

Parameters

start	A Vector2 representing the starting position.
end	A Vector2 representing the ending position.
ignoreWaypoints	A boolean indicating whether to ignore waypoints and return a direct path.

Returns

A tuple containing a list of Vector2 waypoints and a list of integer indices representing lane changes in the path.

x

float SnapController.x

static

Converts Unity coordinates to Carla coordinates.

Parameters

x	A float representing the X coordinate in Unity.
y	A float representing the Y coordinate in Unity.

Returns

A tuple containing the X and Y coordinates in Carla.
