physics_particle_count

Retrieve the number of particles currently active in a physics simulation.

语法：

physics_particle_count()

返回： Real（实数）

描述

This function will return the number of particles that are active in a physics enabled room.

例如：

if physics_particle_count() < physics_particle_get_max_count()
   {
   physics_particle_create(0, x, y, 0, 0, c_white, 1, 1)
   }

The above code will check to see if there are less than the maximum number of permitted particles in the room, and if so create one more.
