Example 1 with NullPointException

use of me.wobblyyyy.pathfinder2.exceptions.NullPointException in project Pathfinder2 by Wobblyyyy.

the class TrajectoryBuilder method fastTo.

Example 2 with NullPointException

use of me.wobblyyyy.pathfinder2.exceptions.NullPointException in project Pathfinder2 by Wobblyyyy.

the class Pathfinder method splineTo.

/**
 * Create a spline trajectory to a certain target point, and then follow
 * that aforementioned trajectory.
 *
 * <p>
 * If this method is called on a set of points with non-monotonic Y
 * values, this will instead invoke
 * {@link #multiSplineTo(double, double, Angle, PointXYZ...)}, which
 * supports non-monotonic Y values.
 * </p>
 *
 * @param speed          the speed at which the robot should move. This
 *                       is a constant value.
 * @param tolerance      the tolerance used for determining whether the
 *                       robot is at the target point.
 * @param angleTolerance same thing as {@code tolerance}, but for the
 *                       robot's angle.
 * @param points         a set of control points for the spline. This
 *                       will automatically insert the robot's current
 *                       position into this array. This array must have
 *                       AT LEAST two points.
 * @return {@code this}, used for method chaining.
