Example #1

File: move_on_line.py Project: NAJILUC/PropaGator

def main(nh, point, direction, offset = 0.0, flip = False):
    boat = yield boat_scripting.get_boat(nh)

    print 'Direction:', direction * 180 / np.pi
    yaw = direction[2]
    print 'Yaw:', yaw * 180 / np.pi
    print 'dx:', np.cos(yaw) * offset
    print 'dy:', np.sin(yaw) * offset
    print 'Point:', point
    point = point + [np.cos(yaw) * offset, np.sin(yaw) * offset, 0]
    if flip:
        direction[2] = (direction[2] + np.pi) % (2*np.pi)

    yield boat.move.set_position(point).set_orientation(rotvec_to_quat(direction)).go()
