physics_particle_get_group_flags(group)
| 参数 | 描述 |
|---|---|
| group | The particle group to get. |
返回： Real（实数）
With this function you can retrieve the group flags for 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.
var flags = physics_particle_get_group_flags(group, flags);
if flags != phy_particle_group_flag_solid | phy_particle_group_flag_rigid
{
flags = phy_particle_group_flag_solid | phy_particle_group_flag_rigid;
physics_particle_set_group_flags(group, flags);
}
The above code will create a variable to store the flags value and then use it to check the flags of the group indexed in the variable "group". If they are not the same, the group is set with these flags.
