physics_particle_group_get_mass

With this function you can retrieve the mass 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().

Syntax:

physics_particle_group_get_mass(group)

Returns:

Real

Example:

var _mass = physics_particle_group_get_mass(group1);

The above code will get the mass of the particle group indexed in the variable "group1" and store it in a variable.
