You need to make a calculation based upon the rect of the vectorShape
sprite.
Here, pntToconvert is a point in the vertex list of a vector shape member,
prctDisplayArea is the rect of the vector shape sprite. It returns the
equivalent point on the stage.
on vpntPointToStage pntToConvert
pntToReturn = pntToconvert +
point(prctDisplayArea.left,prctDisplayArea.top)
return pntToReturn
end
Here is the reverse calculation which converts the point on the stage (ie.
the mouseloc) to a point in the castmember which you can then add to the
vertex list.
on vpntPointToMember pntToConvert
pntToReturn = pntToconvert -
point(prctDisplayArea.left,prctDisplayArea.top)
return pntToReturn
end
Note that if you are scaling the vector sprite things get more complex.
Hope this helps,
Steph
