property
sprite...intersects
Usage
-- Lingo syntax
sprite(sprite1).intersects(sprite2)
sprite sprite1 intersects sprite2
Description
Keyword; operator that compares the position of two sprites to determine whether the quad of
sprite1 touches (TRUE) or does not touch (FALSE) the quad of sprite2.
If both sprites have matte ink, their actual outlines, not the quads, are used. A sprite’s outline is
defined by the nonwhite pixels that make up its border.
This is a comparison operator with a precedence level of 5.
Note: The dot operator is required whenever sprite1 is not a simple expression—that is, one that
contains a math operation.
Example
This statement checks whether two sprites intersect and, if they do, changes the contents of the
field cast member Notice to “You placed it correctly.”:
if sprite i intersects j then put("You placed it correctly.") \
into member("Notice")
