Activate an animation

I’ve spent some hours to figur out how to activate an object animation by clicking 3 other animations in a certain order. For instant:

I have 3 objects with animations. I want to touch object 2, 1 and 3 to activate this other animation (object 4). How is it possible?

I’ve been trying with logic bricks with no success. Do I have to use python to achive this?

Python and a vector dimension 3 for save the order for example

Okey, thanks. I will try to do that :slight_smile:
