Destructible Objects
Hi !

How to do any object destructible ?
I load all destructible objects with this:
Code:
.setObjType(Items,OBJ_DESTRUCTIBLE)
But, what next ?

RE: Destructible Objects
you need to use Game::Destructible class, and pre-generate destructible mesh in Model Editor\Destructible mode

no need to do anything, just check that provided world has custom parameter for destructible object - path for .destruct file

RE: Destructible Objects
Sory... bu I have again problem :/

How to do this:

Mesh must change to destructible object when any physic i active on him.

PL:


Mesh musi zamienić się w zniszczalny wtedy gdy jakaś siła na niego działa.

hmm...
In function 'create' set object as static and when you detect collision set as destructible. Use the functions:
Code:
Game::Destructible barrel;
barrel.toStatic();
barrel.toPieces();

RE: Destructible Objects
It works but when I create new world:

Code:
if(Kb.b(KB_R ))Game::World.New("world/game.world");

it doesn't work.

My code in function Update:
Code:
REPA(Items)
    {
        Items[i].toStatic();
    }

I think that toStatic you should put in Create not Update as Harton wrote.

Harton Wrote:In function 'create' set object as static

Code:
// in MyDestructible.h

class MyDestructible : public Game::Destructible
{
     virtual     void create  (Game::ObjParams &obj);
     virtual     Bool update ();

     // other functions
};



// in MyDestructible.cpp

void MyDestructible::create(Game::ObjParams &obj)
{
     __super::create(obj);
     T.toStatic();
}

Bool MyDestructible::update()
{
     // probably
     REPA(T.actors)
          if(T.actors[i].collision())
               T.toPieces();
}

I checked my code and found error...
I have :
Code:
class Spell : public PhysCutsCallback
{
public:
     Bool   hit       (Int group, Ptr user, Game::Obj *obj);
     Bool   update ()

     Actor tester_shape;
     //...
};

Bool Spell::hit(Int group, Ptr user, Game::Obj *obj)
{
     // ...

     if(obj && (obj->type() == OBJ_DESTRUCTIBLE))
     {
          G::Destruct* target = static_cast<G::Destruct*>(obj);

          target->toPieces();
     }

     // ...

     return true;
}

Bool Spell::update()
{
     switch(type)
     {
     case E::SPELL_1:
          particle.matrix = tester_shape.matrix();
          particle.update();
          particle2.matrix = tester_shape.matrix();
          particle2.update();
          tester_shape.cuts(*this);
          break;
     }

     // ...
}
and I have a class MyDestructible presented in the post above.

When I add line:
Code:
T.toStatic();
in function create in class MyDestructible, game is crashs and debugger shows error in line
Code:
tester_shape.cuts(*this);
in function update, in class Spell.
When I remove line
Code:
T.toStatic();
everything run very well...

Anyone knows what is wrong in my code? Because for me it is correct...
