physics_particle_get_gravity_scale

Get the current gravity scale factor as defined for all particles.

语法：

physics_particle_get_gravity_scale()

返回： Real（实数）

描述

With this function you can find out what the current gravity scale factor is for particles in the physics simulation (you can set this value using physics_particle_set_gravity_scale()).

例如：

physics_particle_set_gravity_scale(physics_particle_get_gravity_scale() + 0.1);

The above code will set the gravity scale.
