physics_particle_count

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

Syntax:

physics_particle_count()

Returns:

Real

Example:

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.
