Slider tute math problem

1

yo,
i don’t understand the math behind the slider tute in the flash 5 section of kirupa’s tutes. That is, i have a movie that is 650 by 500 that i want to slide. can someone explain what i have to change in the formula to get this to slide the exact same was as in the tute? i tried changing some of the numbers and got it almost perfect but ive been doing it with trial and error and its not the most efficient way

thanks

Well let us put it this way…

You have 4 blocks. Each block is 100 pixels wide.

The equation is…

_root.xnew = _root.mask2._x +(4-1)*100/2;

See any correlation?

:slight_smile: No problem man. I myself have never done the tutorial, so I don’t know how right I am, but to me when I map it out in my head I get what I posted last time… but my head isn’t always right :stuck_out_tongue:

I hope it works out for you :slight_smile:

Yeah, that equation isn’t very clear, hue? Actually, the problem comes from the fact that the registration point of the blocks are in their middles, hence the “/2” (would be easier to align them on the left).
