I think I already tryed it before.
But I tryed it again now and no still nothing ...
It's indeed asking me which animation now
So i put the name of the first picture a.k.a "A0" for me
that A0 is set to loop on and speed 5
on my sheet :
System / on Start of layout / Sprite / set animation to A0 (play from begining )
I think I miss something very stupid
So I'll explain step by step what i do :
right click , insert new object , sprite.
right click on this sprit, edit animation, open image1.
in the animation window , right click add animation , left click on that new animation there a blank window where i open image 2.
Etc... for 5 images.
so basicly is something like
img 1 .O.
img 2 .O/
img 3 \o.
img 4 \O/
img 5 o//
What i'd like is when i run layout the sprit move all those image in a loop ( like a gif picture or something like that )
