Scaling Physics Bodies in Xcode Spritekit

Question

I recently came across an issue where I would increase the size of a node, but the physics body would remain the same size. I tried to look up solutions to this with no succ

Answer 1

this is strange you can do it add physics body before adding it to the SKNode or SKScene for e.g.

SKTexture  *texture=[_gameTexture textureNamed:@"mysprite"];
SKSpriteNode *bubble=[SKSpriteNode spriteNodeWithTexture:texture];
bubble.anchorPoint=CGPointMake(0.5,0.5);
//_bubble.name=[@"bubble" stringByAppendingFormat:@"%d ",index];
bubble.name=newcolor;

// _bubble.userInteractionEnabled=YES; _bubble.position=CGPointMake(newPosition.x, newPosition.y);

//
bubble.physicsBody=[SKPhysicsBody bodyWithCircleOfRadius:60];
bubble.physicsBody.dynamic=NO;
bubble.physicsBody.linearDamping=0;
bubble.physicsBody.restitution=0;


bubble.physicsBody.density=1;
bubble.physicsBody.allowsRotation=NO;
bubble.physicsBody.affectedByGravity=NO;
//_bubble.physicsBody.velocity=CGVectorMake([self getRandomNumberBetween:-10 to:7], [self getRandomNumberBetween:-10 to:7]);
//  _bubble.physicsBody.usesPreciseCollisionDetection=YES;


bubble.physicsBody.categoryBitMask=ballCategory;
bubble.physicsBody.collisionBitMask=ballCategory | pathCategory ;
bubble.physicsBody.contactTestBitMask=ballCategory | pathCategory ;

[self addChild:_bubble];


bubble.xScale=_bubble.yScale=2;
bubble.alpha=0.5;
