How do I this (Advanced Families)

Ok I have a specific problem with families. I have a Family test and into it there is a Sprite

So I have also a variable for all objects from family,

basic and easy, no? Then I create 3 instances from that family , in 2 instances I set 0 in its variable and the third I set a 1

So far so good. The problem is complicated here, I need to when collides family test with family test

Only are destroyed the instances, for example:

test.Variable=1 with test.Variable=0, they are destroyed

test.Variable=0 with test.Variable=1, they are destroyed

but other hand if

test.Variable=0 with test.Variable=0, they are not destroyed

I have tried many things, but I don't sure if that is possible

Thanks in advance

The trick here is always to test against different objects. Either test Family against Sprite, or make a second duplicate family to test against.

Yea blackhornet and thanks for reply, that is my second option, but that doubt arose. I think that should be possible, ie, I can getting the IID for instance but I cant compare at same time 2 instances from same sprite when collides.

Anyway thanks
