sprite...intersects

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. The Matte ink does not work with vector shape sprites.

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"
