how to not rotate around object

tutorial 09

I have 2 objects: player and obj

Code:


SIO2object *object = ( SIO2object * )sio2ResourceGet( sio2->_SIO2resource,
                                                  SIO2_OBJECT,
                                                  "object/player" );
         
         
         ....
         code for player
         ....
         
         SIO2object * obj = ( SIO2object * )sio2ResourceGet( sio2->_SIO2resource,
                                              SIO2_OBJECT,
                                              "object/obj" );

         obj->_SIO2transform->loc->x = object->_SIO2transform->loc->x ;
         obj->_SIO2transform->loc->y = object->_SIO2transform->loc->y + object->dim->y + 1.5;
         obj->_SIO2transform->loc->z = object->_SIO2transform->loc->z;

         obj->_SIO2transform->rot->z = ROTZ;
         
         
         sio2TransformBindMatrix(obj->_SIO2transform);

         obj->_btRigidBody->getWorldTransform().setFromOpenGLMatrix( obj->_SIO2transform->mat );


need to obj does not rotate around the player.

How do it? Please help

Thanks!!!!!

You can calculate it using sin and cos. If you don't want to do the math your self you can look on sio2Rotate3d function(used in tutorial 9)

what you mean?

now me obj rotate around player, i need it does not rotate around player and it was behind

Do you want the object to rotate around it origin? Then you select your object in blender and press "center new" or what ever it is, just watch one of the tutorials if you can find it, now it should work modifying the object->_SIO2transform->rot vector. I thought you wanted the object to rotate around your player

thanks

i did it, but when i move my player left or right my obj rotate around player

********!!!!! uuuu

obj->_SIO2transform->_SIO2parent = object->_SIO2transform;

handle parent to child

Check tutorial14 for more info about parenting & physic... that's might be part of what you are looking for...

Code:

SIO2object *parent = ( SIO2object * )sio2ResourceGet( sio2->_SIO2resource,
                                    SIO2_OBJECT,
                                    "name parent" );
SIO2object *child = ( SIO2object * )sio2ResourceGet( sio2->_SIO2resource,
                                    SIO2_OBJECT,
                                    "name child" );
 
child->_SIO2transform->_SIO2parent = parent->_SIO2transform;
