Hi Richmond You’ll want to use the optional threshold parameter for the intersect function.
intersect(object,object [,threshold] ) Probably in your case either “pixels” or “opaque pixels”! >From the Dictionary: Use the intersect function to determine whether one object obscures part of another object, or whether one object is over another object. Parameters: object - an object reference. threshold - The amount of transparency that pixels in the objects must have in order to be counted during the intersect calculation. • alpha value - An integer between 0 and 255 which specifies a threshold that the alpha value of each pixel must be greater than or equal to in order to be counted during calculation of the intersect. Alternative (readable) theshold options • "bounds" - (Equivalent to using an alpha value of 0) Specifies that the intersect is calculated using the rect of the two objects. • "pixels" - (Equivalent to using an alpha value of 1) Specifies that the intersect is calculated using pixels of the objects that have are not completely transparent, ignoring completely transparent areas. • "opaque pixels" - (Equivalent to using an alpha value of 255) Specifies that the intersect is calculated using only pixels that are completely opaque.
