physics_particle_group_get_vel_y(group)
| Argument | Description |
|---|---|
| group | The particle group to get. |
Returns: Real
With this function you can retrieve the vertical velocity of a
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.
vx = physics_particle_group_get_vel_x(group1);
vy = physics_particle_group_get_vel_y(group1);
The above code will get the horizontal and vertical velocity of the particle group indexed in the variable "group1" and store them in variables.
