Collision between two instances of a same object

[DavidT]

Hello,

I would like to do this condition: Collision between [Active1 with Direction=0] and [Active1 with Direction=16]
But I don't know how to do it. I only manage to do this: Collision between Active1 and Active2 with both Direction=0

Is there a way to do what I want and how?

Man this is a tough one. You could create exterior objects that follow them when they're going one direction and don't move when they're going another.

i.e., Direction = 1, position pink square to object; Direction = 16, position green square to object; pink square collides with green square, etc.

What exactly are you trying to do?

Thanks Ziplock. I am not doing exactly what you propose but it's quite the same : splitting my object into two different objects, one with the direction 0 ("normal fish") and one with the direction 16 ("zombie fish"). It complicates programming because I have to often create/destroy objects and transfert their values, but it works well.

Why again are you using directions? With your description in mind, can't you just have 2 different objects that act the same way rather than using directions. When a "normal fish" turns into a "zombie fish," create a zombie fish at the position of the normal fish and destroy the normal fish. Then it's as simple as when a zombie fish collides with a normal fish.

I explained bad. I am actually doing the same as what you say
