physics_particle_group_get_angle(group)
| 参数 | 描述 |
|---|---|
| group | The particle group to get. |
返回： Real（实数）
With this function you can retrieve the rotation (angle) in the
room of a group of particles. The group value is that
which was returned when you created the group of particles using
the function physics_particle_group_end,
and the function will return a value which is the combined value of
the currently set flags.
ang = physics_particle_group_get_angle(group1);
The above code will get the angle of the particle group indexed in the variable "group1" and store it in a variable.
