Code for collision of top of shape...

Hey..

Im trying to write my fishing program and im getting stuck on the coding for a collision which only occurs if the y2 part of the line pierces the top of a shape. The shape must be hit by the y2 part of the line not at the middle of the line or ne thing. The shape is 495 x 255 (a rectangle) and is hidden underneath a fish that scrolls across the screen. I need it so when the fisher casts his line and the line hits any part of the top of the shape then the collision even occurs. Any help?

Thanks,

edit: Ok I found out a way to work it, though it is limiting. The line before didnt completely become equal to the top of the shape :

If Line1.Y2 = Shape1.Top And Line1.X2 >= Shape1.Left Then fish4.Visible = False

so I adjusted the shape and fishes position so now it does become equal so it works...but that is limiting because now i have to make the fish in set positions if the line is to become equal. Any way around this?

I didn't understand the question...

Of the top of my head...

VB Code:

If Line1.Y2 >= Shape1.Top And Line1.Y2 <= Shape1.Top + Shape1.Height And Line1.X2 >= Shape1.Left And Line1.X2 <= Shape1.Left + Shape1.Width Then
    Fish4.Visible = False
End If

If the line's X2,Y2 point is within the shape this will hide the fish, which is what you want i think.
