If you say to create an object and specify a family, what should happen instead? There's no one particular object that should be created, so it picks a random one.
but when you move a families it pick all object of the families.
When you destroy a families it pick all object of the families
So why this didnt pick all object when you create object families ?
I hope this make sense, sorry for my english.
I think we need a fonctionnality for connect multiple object. For example life bar : if i made a collision with a sprite i modify the life bar connect with the sprite.
I tested IID and this didnt work fine, This made a lot of bug in my programm. Finally i used pick nearest but if two lifebar overlap this made a bug too......
