Hi All,
I’m trying to figure out a way to have objects snap to a grid on the mouseUp. I
have a list of TopLeft coordinates.
500,50
500,125
500,200
500,275
400,50
400,125 …
I want the object to snap to the closest topLeft coordinate in the list upon a
mouseUp.
I was tried subtracting current x and y coordinate from each item in list, but
that quickly was getting complicated.
on mouseUp
put the topLeft of me into tMyLoc
put item 1 of tMyLoc into tXLoc
put item 2 of tMyLoc into tYLoc
put 1 into tItem1
put 1 into tItem2
put 1 into x
repeat for number of lines in cd fld 1
put item tItem1 of line x of cd fld 1 into tXTarget
put item tItem2 of line x of cd fld 1 into tYTarget
put the abs of (tXTarget - tXLoc) & "," after tCoords
put the abs of (tYTarget - tYLoc) & return after tCoords
add 1 to x
end repeat
put "My Current Loc:" && tMyLoc after tCoords
answer tCoords
end mouseUp
on MouseDown
Grab me
end MouseDown
Interesting it appears the smallest abs result of the subtraction seems to be
the closes x coord listed. But that only gets me half way there. I thought I’d
throw it out here for suggestions…?
Thank you!
