Rollover buttons

Programming Questions

I have a series of rollover buttons arranged in a ring. The ring can be moved around the screen, but wherever it is, the actual spots that trigger the rollover-effect are always stuck in one place.

the applet can be found here: here. It's easy to see the problem, but confusing for a beginner to work out how to solve.

I think it is connected to the way I am moving my object (the ring of buttons) using translate(), because its screen location (0, 0) moves around when dragged with the mouse.

- can anyone suggest a way to make both parts of the buttons line up?

- or even a way to find out the 'real' x & y for my object when it thinks it is at (0, 0) but has been translated?

Thanks! L.

This is one of the reasons I tend to avoid using translate: you think it makes things simpler and then it comes back and bites you.

Presumably you store the centre location of the circle somewhere... So the solution is probably just to add this as an offset to the coordinates you're using when checking mouseOver. TBH there's a lot of code here and lots of dependencies (SVG files, text files etc.) so it's not easy to debug or test. You may find that creating a separate sketch that addresses just this problem will make it a lot easier for you to figure out a solution; and also a lot easier for us to offer you help.
