[SOLVED] Physics body slides back after collision

cocos2d-x C++
1

I have a dynamic body that slips when it lands on a static physics body and it also slips sometimes after a collision with a static body.I have set the restitution of my static body to 1. I am using the default Chipmunk

This is how I am creating my wall/floor which is static

    Sprite* sp = Sprite::create();
    sp->setContentSize(Size(w,h));
    sp->setPosition(SetAnchorFromCenter(Vec2(x,y), sp->getContentSize()));
    PhysicsBody* pb= PhysicsBody::createEdgeBox(Size(w,h),PhysicsMaterial(0,1,0),1,tileMap->getPosition());
    //pb->setContactTestBitmask(true);
    pb->setDynamic(false);
    sp->setPhysicsBody(pb);
    this->addChild(sp);

This is how I am creating my dynamic object

sprite_eagle = Sprite::createWithSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName("tmp-10.gif"));
    sprite_eagle->setPosition(50,450);
    sprite_eagle->setAnchorPoint(Vec2(0.5,0.5));
    this->addChild(sprite_eagle);

    //Create the physics body for the sprite_eagle
    PhysicsBody* sprite_eagle_body= PhysicsBody::createCircle((sprite_eagle->getContentSize().width)/2,PhysicsMaterial(0,0,0));
    sprite_eagle->setPhysicsBody(sprite_eagle_body);

I believe a physics body by default is dynamic.

This is how I am moving my object

sprite_eagle->getPhysicsBody()->setVelocity(vel);

Any suggestion on why my dynamic body sprite is sliding ?

Did you try adding friction?

I just changed the logic to fix this problem. When I am not pressing the move button I changed the velocity to Vec(0,0) as a result the body stops.
