Scratch

My minor (but important) revelation was yesterday when i discovered a block in the Sensing section.

< value > of < sprite >

(Unfortunately it's not been aded to the list of 'Adding Scratch Blocks', so there's no pic of it)

The key thing is of course that you can then access a value of the Sprite you've selected from another... where that value can be the size or position, or (even more usefully) the values of it's Local variables... without needing to create and update gazillions of Global variables.

Which is a big help when dealing with lots of sprites that are similar, as you can just create Local vars and then Duplicate the sprite without having to create new Globals and drag them in to replace the existing ones!

So if there's one thing I'd show to a wannabe Advanced Scratcher, it's that block... it could save them a lot of time and effort
