初学无知 求助各位大侠！！！！
结构体定义如下：struct excursions{signed int direction;
int remove;
} excursions;
struct deflexion{signed int direction;
int angle;
} deflexion;
struct body_coordinates{
signed long int right_x_coordinates;
signed long int right_y_coordinates;
int x_coordinates_increment;
int y_coordinates_increment;
} body_coordinates;
struct swy_body_property{
struct body_coordinates body_coordinates;
float showy_body_direction;
float swy_a;
float swy_a_direction;
float swy_v;
float swy_v_direction;
struct excursions swy_displacement；
struct deflexion swy_angle；
} swy_body_property;
报错位置为下述各句：
void body_adjust(int a,struct swy_body_property* current_property)
{
switch(a){
case 0x7777：
* current_property->swy_displacement->direction=0;
* current_property->swy_displacement->remove=0;
* current_property->swy_angle->direction=0;
* current_property->swy_angle->angle=0;
break;
case 0x7377：
* current_property->swy_displacement->direction=1;
* current_property->swy_displacement->remove=remove1;
* current_property->swy_angle->direction=1;
* current_property->swy_angle->angle=l_angle8;
break;
case 0x7773:
* current_property->swy_displacement->direction=-1;
* current_property->swy_displacement->remove=remove1;
* current_property->swy_angle->direction=-1;
* current_property->swy_angle->angle=l_angle8;
break;
case 0x7767:
* current_property->swy_displacement->direction=1;
* current_property->swy_displacement->remove=remove1;
* current_property->swy_angle->direction=-1;
* current_property->swy_angle->angle=l_angle8;
break;
case 0x6777:
* current_property->swy_displacement->direction=-1;
* current_property->swy_displacement->remove=remove1;
* current_property->swy_angle->direction=-1;
* current_property->swy_angle->angle=l_angle8;
break;
