Box2d碰撞问题

Question

I'm creating a physics game and in my game there are many kinds of balls.
now, there's a special ball that suppose to pass through walls, but other balls
can collide with it (so only walls wouldn't "feel" the special ball).

I didn't figure how to id exactly.
what is the best practice?

thanks,

您可以在球对墙碰撞检查逻辑上附加条件，以仅在球不是特殊类型时检查/允许弹跳
