/**
 * A continuous laser beam that extends outward from its origin along a direction vector.
 * <p>
 * Unlike other projectiles, lasers don't move through the world — they extend from their
 * origin point along a direction, hitting everything in their path up to {@link #getMaxLength()}.
 * The direction can be set explicitly via {@link #setDirection(double, double, double)}.
 * <p>
 * The coordinate-based {@code fireAt(x, y, z)} calculates and sets the direction vector
 * automatically, then uses the laser's internal launch sequence.
