Struct Cursor

Public

Represents a single point on the polyline represented by the PathInterpolator.

The cursor is a lightweight structure which can be used to move backwards and forwards along a PathInterpolator.

If the PathInterpolator changes (e.g. has its path swapped out), then this cursor is invalidated and cannot be used anymore.

Public Methods

EstimateSmoothCurvature (tangent, smoothingDistance, expectedRadius)
EstimateSmoothTangent (normalizedTangent, smoothingDistance, expectedRadius, beforePathStartContribution, forward=true, backward=true)
GetRemainingPath (buffer)

Appends the remaining path between position and endPoint to buffer.

GetTangents (t1, t2)

The tangent(s) of the curve at the current position.

MoveToCircleIntersection2D<T> (circleCenter3D, radius, transform)
MoveToClosestIntersectionWithLineSegment (origin, direction, range)

Moves to the closest intersection of the line segment (origin + direction*range.x, origin + direction*range.y).

MoveToClosestPoint (point)

Move as close as possible to the specified point.

MoveToLocallyClosestPoint (point, allowForwards=true, allowBackwards=true)
MoveToNextCorner ()

Moves the cursor to the next geometric corner in the path.

MoveToSegment (index, fractionAlongSegment)

Move to the specified segment and move a fraction of the way to the next segment.

MoveToSphereIntersection (sphereCenter, radius)
MoveWithTurningSpeed (time, speed, turningSpeed, tangent)

Moves the agent along the path, stopping to rotate on the spot when the path changes direction.

Public Static Methods

IntegrateSmoothTangent (p1, p2, tangent, distance, expectedRadius, smoothingDistance)
IntegrateSmoothingKernel (a, b, smoothingDistance)

Integrates exp(-|x|/smoothingDistance)/(2*smoothingDistance) from a to b.

IntegrateSmoothingKernel2 (a, b, smoothingDistance)

Integrates (x - a)*exp(-x/smoothingDistance)/(2*smoothingDistance) from a to b.

StartOfPath (interpolator)

A cursor at the start of the polyline represented by the interpolator.
