Hi !
I have problem. How to join explosions with physics ?

Więc jeśli by to było możliwe prosiłbym o odpowiedź po polsku.

You can add forces/impulses to all nearby actors.

Ok, thanks. But how to do it ? I'm already start with Esenthel.

Game::World.objGet will give you a list of objects, in each of them
Actor::addImpulse or something like that

I wrote this. But it doesn't work.

Code:

Memc<Game::Obj*> objs;

    if(Kb.bp(KB_SPACE))

   {

       explosion.create(main, single, Color(96,20,0,0), 80, Vec(0,0,0), 1);

        //ball.addImpulse(Vec(0,1,1));

        Vec tempPos = ball.pos();

        Game::World.objGet(objs,Ball(2,tempPos)); 

        REPA(objs)

              {

                     Actor *item = CAST(Actor, objs[i]);

        item->addImpulse(Vec(0,1,1));

            }

   }

   }

you can't cast Game::Obj to Actor,
check for example Game::Item (which can be casted), it has member 'actor'

Ok, i have now this:

Code:

if(Kb.bp(KB_SPACE))

   {

       Memc<Game::Obj*> objs;

       explosion.create(main, single, Color(96,20,0,0), 80, Vec(0,0,0), 1);

        //ball.addImpulse(Vec(0,1,1));

        Vec tempPos = Vec(0,0,0);

        Game::World.objGet(objs,Ball(3,tempPos)); 

        REPA(objs)

              {

                  Game::Item *item = CAST(Game::Item, objs[i]);

                        item->actor.addImpulse(Vec(0,1,1));

            }

   }

It doesn't work. What do Flt r in

Code:

Game::World.objGet(objs,Ball(3,tempPos));

?

in Ball r is radius.

darkking · 12-05-2010 08:00 PM

So, it get all objects around 3f from explosion ? Why it doesn't work.

Check tutorial Game Basics/Big Overlays. It should helps you.
