SKPhysicsBody and [SKNode setScale:]

by

Using either an SKAction or the Update loop, you can create a new SKPhysicsBody with the proper scale and apply it to the object. However, by doing so, you will lose the velocity. To fix this, you can do the following:

SKPhysicsBody *newBody = [SKPhysicsBody bodyWithRectangleOfSize:boxObject.size];
newBody.velocity = boxObject.physicsBody.velocity;

boxObject.physicsBody = newBody;
