Stacked – A Cone is Stacked on a Goal if it is not touching a Robot of the same color Aliiance as the
Goal and either:
a) Fully nested on a Goal (see Figures 5 & 6).
b) Fully nested on a Stacked Cone (see Figures 7 & 8).

The intent is for Stacked Cones to only count on upright Mobile Goals.

Upon reading the post my interpretation is that stacked cones are only scored if they are at upright position, and those cones described in the question are stacked.if the cones are sideways and fully nested on a mobile goal that is also sideways, are the cones considered to be stacked? in the other word, would it be a violation of SG9? Can we tilt the mobile goal and put cones on it and tilt it back to upright position after?
Thanks in advance!

This is a correct interpretation.

if the cones are sideways and fully nested on a mobile goal that is also sideways, are the cones considered to be stacked?

in the other word, would it be a violation of SG9

No, they would not be Stacked; yes, it would be a violation of <SG9>. Per Note 3 of the definition of Stacked, “Cones are not considered Stacked unless the Goal upon which they are fully nested is upright.” The Cones in this photo would not be considered upright, which means they would not be considered Stacked, which in turn means they would be in violation of <SG9> if being controlled by a Robot.

Can we tilt the mobile goal and put cones on it and tilt it back to upright position after?

No, because while the Mobile Goal is tipped over, it is not considered a legal stack.
