I've made some changes to the example provided with clutter-box2d to
illustrate my issue. You'll notice that you can see the left most hand
'attempt' to move but doesn't (or can't).
**************
scene-table.c (I also changed util.c [add_hand function] to name the actors)
**************
#include <clutter/clutter.h>
#include "clutter-box2d.h"
#include "blockbox.h"
ClutterActor *move;
gboolean moveactor(void)
{
printf("TIMEOUT\n");
gint x,y;
clutter_actor_get_position (move, &x, &y);
printf ("X: %i Y:%i\n", x, y);
clutter_actor_set_position (move, x + 1, y - 1);
return TRUE;
}
void
scene_table (Scene *scene)
{
ClutterActor *stage;
ClutterActor *group;
ClutterVertex gravity = {0,0};
gint i = 10;
stage = clutter_stage_get_default ();
group = clutter_box2d_new ();
add_cage (group, TRUE);
scene->group = group;
clutter_group_add (CLUTTER_GROUP (stage), group);
clutter_box2d_set_simulating (CLUTTER_BOX2D (group), simulating);
g_object_set (group, "gravity", &gravity, NULL);
while (i--)
{
gint x, y;
x = clutter_actor_get_width (clutter_stage_get_default ()) / 2;
y = clutter_actor_get_height (clutter_stage_get_default ()) * 0.8;
clutter_container_child_set (CLUTTER_CONTAINER (scene->group),
add_hand (scene->group, x, y),
"manipulatable", TRUE,
"mode", CLUTTER_BOX2D_DYNAMIC,
NULL);
}
move = clutter_container_find_child_by_name ( CLUTTER_GROUP (stage),
"hand");
g_timeout_add (1000, moveactor, NULL);
}
