difficult to name thing of thing block#

Use object."property" to read a sprite or Stage property or variable. The object may be an expression; the property must be a string literal.

backdrop_number = "Stage"."backdrop #";
other_score = "main"."score";

([backdrop #] of (Stage v))

Sprite properties include "x position", "y position", "direction", "costume #", "costume name", "size", and "volume". For the Stage, use "backdrop #", "backdrop name", or "volume". To read a variable, use its name as the property string.
