    // If we have no target, then return no steering acceleration
    if (neighborCount == 0 || firstNeighbor == null)
        return steering.setZero();

    // If we're going to hit exactly, or if we're already
    // colliding, then do the steering based on current position.

        relativePosition.set(firstNeighbor.getPosition()).sub(owner.getPosition());
    } else {
        // Otherwise calculate the future relative position
        relativePosition.set(firstRelativePosition).mulAdd(firstRelativeVelocity, shortestTime);
    }

    // Avoid the target
    // Notice that steerling.linear and relativePosition are the same vector

    // No angular acceleration
    steering.angular = 0f;

    // Output the steering
