Can you use "is within" statements to evaluate if an object is within
the confines of an irregular shape??
If so - point me in the right direction?
Thx,

Answered my own question- I found the "intersect" function and it
works (see below)
if intersect(graphic "ball", graphic "sand1") then
put "in the bunker" into YourLie
end if
HOWEVER...
There are many, many objects that the ball object may intersect with...
Is it possible to use
Hi Steve,
Should be fine indeed...
AFAIK yo have to run a loop.
I don't know how is your interface but you could have some invisible
graphics to test a larger zone before a long loop.
A kind of graphic's indexation... to speed up the process if needed :-)

Intersect doesn't work after all. It appears that one object will
intersect with another irregular object's rect and NOT the objects
true shape (polygon points).
See illustration... at:

Is there a way to get Rev to:

Re Steve,
Another funny approach:
function WhichObject pLoc,pObj
local tCurLoc, tColor

put the screenMouseLoc into tCurLoc
lock screen
hide pObj
set the screenMouseloc to globalLoc(pLoc)
put the mouseColor into tColor
set the screenMouseloc to tCurLoc
show pObj
unlock s

Now THAT is an ingenious approach!!! :-)

This is pretty cool!
But - would this work 100% for curved polygons or images?
The docs do not mention points for images.
Either, this is a very cool way of testing.

Images don't have points. You simply test the point against the image

bummer...
I was hoping that you'd found a solution to my need for the sort of
irregularly-shaped buttons that an old HC external provided.

Yup, that's what somebody told me when I asked about it privately some
months ago: "You need to read a book on algorithms"...
Gave up.

It occurs to me that even tho the "intersect" function works with the
bounding rectangle of an object, and not the actual object itself, "intersect"
could nonetheless be useful as a sort of initial screen. If "intersect" doesn't
think the two objects intersect, well, they *can't* intersect, r
