This question was posted in response to the following article: http://help.adobe.com/en_US/Director/11.5/Beginners/WS16484b78be4e154257f095c61304a789ae4- 8000.html
What does rect refers to in this line: vRect = vTarget.rect
vTarget = sprite("Drop")
vRect = vTarget.rect
The rect property of a sprite is an object with the properties left, top, right, bottom, width and height.
vRect = sprite("Drop").rect
-- rect(210, 188, 310, 230)
You can find out more about the rect object >here<.
