Giving Values to Movieclips and adding together!

[arrannknott]

Hello to all - hopefully someone can help!

What I want to do is have a profile of a skyscraper showing a cross section of all the levels. I want people to be able to click on multiple levels of the illustration and as they do this a field on the screen displays a figure which represents (and adds together) the floor space of each level.

eg. If you click on level 21 (200 metres squared) then the field shows 200.
Then if you click level 30 that is (185 metres squared) then the field would show 385. This needs to be able to add multiple levels (probably up to 10)

Would this be possible?!!! If it doesn't make sense drop me a line!!

Cheers!

Sure, it's very doable. There are lots of ways to do it but I'll outline the one I think is most straightforward.

1) Have a separate movie clip for each level. These will be the things you click on to select or deselect a level.

2) Create a "running total" variable and initialize it to 0

3) Add a onRelease function to each of the level movie clips. This will be used to toggle the levels as selected or unselected. You probably want this event to change the appearance of the level so the user can tell whether it's been selected.

4) Have the onRelease add or subtract its level's area from the running total, depending on if it's being selected or deselected. Also update the indicator that shows how much area is selected (use trace() to start with).


It's tough to tell from your post how experienced you are. Let me know what makes sense (if anything) and what doesn't make sense. I'll try to clear it up for you. And good luck!
