physics_particle_group_join(to, from)
| Argument | Description |
|---|---|
| to | The first particle group to join. |
| from | The second particle group to join. |
Returns: N/A
With this function you can join two particle groups together,
and the joined groups will then behave as if they were both part of
a single entity. The groups should have been created with
over-lapping edges, as, if they are not already touching, they will
not be joined. The function takes the unique group IDs of the
groups to join, as returned by the function physics_particle_group_end(),
and you can use the function any number of times for a single group
to join various soft bodies together.
var flags = phy_particle_flag_water |
phy_particle_flag_viscous | phy_particle_flag_tensile;
var groupflags = phy_particle_group_flag_solid;
physics_particle_group_begin(flags, groupflags, mouse_x- 45,
mouse_y, 0, 0, 0, 0, c_white, 1, 1, 2);
physics_particle_group_circle(50);
var g1 = physics_particle_group_end();
physics_particle_group_begin(flags, groupflags, mouse_x + 45,
mouse_y, 0, 0, 0, 0, c_white, 1, 1, 2);
physics_particle_group_circle(50);
var g2 = physics_particle_group_end();
physics_particle_group_join(g1, g2);
The above code creates two circular particle groups and joins them together.
