physics_particle_group_get_inertia(group)
| 参数 | 描述 |
|---|---|
| group | The particle group to get. |
返回： Real（实数）
With this function you can retrieve the inertia of an entire
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.
i =
physics_particle_group_get_inertia(group1);
The above code will get the inertia of the particle group indexed in the variable "group1" and store it in a variable.
