collision and scale :(

Hello

I have problems

If i scaled object then collision is don't working. If scale of object = 1 then all is great!

tutorial 9

Why

Please, help

Thanks!

Bullet doesn't support scaled matrices... and watch the video tutorial06_1 I talk about that in details...

you can remove the physic attribute and then add the physic attribute after you scale the object

how to do it?

please

Code:


SIO2object *object = ( SIO2object * )sio2ResourceGet( sio2->_SIO2resource,
                                           SIO2_OBJECT,
                                           objectName );
   
   
   sio2PhysicRemoveObject( sio2->_SIO2physic, object );
   
   object->_SIO2transform->scl->x = 0.5;
   object->_SIO2transform->scl->y = 0.5;
   object->_SIO2transform->scl->z = 0.5;
   
   sio2PhysicAddObject( sio2->_SIO2physic, object );


this code don't work

sio2PhysicRemoveObject( sio2->_SIO2physic, object );

object->_SIO2transform->scl->x = 0.5;
object->_SIO2transform->scl->y = 0.5;
object->_SIO2transform->scl->z = 0.5;

object->dim->x = object->dim->x * 0.5f;
object->dim->y = object->dim->y * 0.5f;
object->dim->z = object->dim->z * 0.5f;

sio2PhysicAddObject( sio2->_SIO2physic, object );

object->dim->x = object->dim->x * 0.5f;
object->dim->y = object->dim->y * 0.5f;
object->dim->z = object->dim->z * 0.5f;

sio2PhysicAddObject( sio2->_SIO2physic, object );

thanks

camera is work , but not collision

what me doing

You need to adjust the origin of the collision object
