Box2d Create Shape Error

Hello.

Once again I am having trouble with physics.

I have this code:

Code:

bound->CreateShape(bounddef);

It gives me the error:

Here is my entire code for making a floor object:

Code:

-(void)makebound {
    b2PolygonShape bounddef;
    b2FixtureDef boundfix;
    b2BodyDef boundbodydef;
    b2Body* bound;
    b2Vec2 verticies [4];
    b2Vec2(verticies [0]).Set(0 / ratio, 0 / ratio);
    b2Vec2(verticies [1]).Set(550 / ratio, 0 / ratio);
    b2Vec2(verticies [2]).Set(550 / ratio, 10 / ratio);
    b2Vec2(verticies [3]).Set(0 / ratio, 10 / ratio);
    bounddef.Set(verticies, 6);
    boundfix.shape=&bounddef;
    boundfix.density = 0.0;
    boundfix.friction=0.5;
    boundfix.restitution = 0.3;
    bound->CreateFixture(&boundfix);
    boundbodydef.position.Set(0 / ratio, 390 / ratio);
    bound = World->CreateBody(&boundbodydef);
    bound->CreateShape(bounddef);
    
}

What's wrong?

 

I get you.

Well I'm having an issue with b2World.cpp and b2BlockAllocator.cpp.

When ever I run my app I get this:

 

I found the problem is not with this error, it's with this code:

Code:

-(void)createagain {
    b2BodyDef groundBodyDef;
    groundBodyDef.position.Set(0, 0);
    b2PolygonShape groundBox;
    b2Vec2 verticies [4];
    (verticies [0]).Set(0, 0);
    (verticies [1]).Set(550 / ratio, 0);
    (verticies [2]).Set(550 / ratio, 10 / ratio);
    (verticies [3]).Set(0, 10 / ratio);
    int32 vcount = 4;
    groundBox.Set(verticies, vcount);
    b2Body* groundBody = World->CreateBody(&groundBodyDef);
    groundBody->CreateFixture(&groundBox, 0);
}

What's wrong with this code?

 

Found out the problem was that is needed to be in the viewdidload function.

Stay tuned!

I might need some more help!

 

I finally got it!

Thanks for all the help!
