Drag and Drop

[Altruistic]

I am working on a drag and drop that deals with balance. I have a scale with a bag full of objects in it. This bag is on the left side of the scale and weighs it down. As you drag items from the bag, I want to have the angle of the scale change. I am lost on this on. Can someone help?

Some hints for you...

Give each item in the bag a variable.
Numbers would be good.
E.g. item1=2
Set a variable when all the items are in the bag.
Eg. totalweight=100
Set a variable for the angle - angle = (startvalue)
Then:
If (totalweight==100)all items in the bag
angle = 100
now when you remove an item you must affect the totalweight
variable by subtracting the value of the item variable from the totalweight variable.
Then have the new totalweight again effect the angle variable:
If (totalweight==newvalue)
angle=(newvalue)
You could make your scale graphic a circle with a line through the centre being the only visible feature and set uo a relationship like
onenterFrame
_rotation = totalweight/180

Hope this gets yer mind going.

Thank a lot! I will try this out and may have some more questions if you have the time. Your assistance is greatly appreciated!

I have one more question if you have the time. When I am giving a value to each item, if there are 10 items, and the total weight is 100, would each have a value of 10? How would I set this up. Would it be item1=10?

[ricktor]

Give each item any value you want as long as the whole load adds up to 100 or whatever you wish the totalweight to be.

So yes, the items could all have the same value, but that would'nt be so realistic would it? Use whole numeric values though, it will make life easier.

Make an Mc give it a variable of say weight=20.
Make another Mc, a circle, with a line through it so you can observe any change in rotation.
Put both of them on the timeline and give them instance names.
In the circle put code along these lines:
On enterframe
_rotation = _root.(otherMc).weight

Test it and I think you'll get the idea.
Got to go home now.
Talk again later.
