Destructible Objects

Hi !

How to do any object destructible ?
I load all destructible objects with this:

Code:

.setObjType(Items,OBJ_DESTRUCTIBLE)

But, what next ?

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

But, how to load all elements to this class ?

there is an available World "destructible.world", run it in World Editor

I create custom scene with destructible object but how to load it in my project ?

I wrote this:

In head of code:

Code:

Game::ObjMemx<Destructible> Items;

In Init:

Code:

.setObjType(Items,OBJ_DESTRUCTIBLE)

But what in Update ? Sory, but I don't know.

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

Objects has this parameters but i have error:

Quote:error C2065: 'Destructible' : undeclared identifier

This is it:
Game::ObjMemx<Destructible> Items;

Code:

Game::ObjMemx<Game::Destructible> Items;

Ok, it's works smile

thx

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();

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...
