How do I create object and control opacity with touch?

Opacity from first created to last, last created being 100% ?

Or for the first 4 created only.

Thank you, but this not working as my image example above.

Look, to understand. Let's say we create 10 boxes. So, we have:

First Creation: 1 => Opacity: 100

______Creation: 2 => Opacity: 100

______Creation: 3 => Opacity: 100

______Creation: 4 => Opacity: 100

______Creation: 5 => Opacity: 100

______Creation: 6 => Opacity: 100

______Creation: 7 => Opacity: 100

______Creation: 8 => Opacity: 70

______Creation: 9 => Opacity: 40

Last Creation: 10 => Opacity: 10

Something like this. Of course, what extra need is to have creations depend distance. But again, thanks for your help! :)

This will give you 60,40,20 for the last 3 created.

So 15 objects would be 80,60,40,20

You can mess around with the math to adjust.

Cool, thanks for this help!

But unfortunately the best will be to controlled via distance + new creation each time.

Because in this example we have 10, or whatever boxes. And opacity will always be set default no matter mouse/touch is (in this example last 3 creations).

If for some reason can made a new creation each time we have touch X/Y would be perfect. :)

Like the example below:

Please note: Touch X in this image, it's just an example. The control remain as original, use X,Y and angle.

If I understood correctly ?, this will adapt to any object count, and just effect the last 3 boxes.

Sorry last pic I forgot to put an event in.

Revised below.

I still don't understand what you exactly want?

Yes i already fix it myself. But still no make sense to me, sorry.

As i said, it create already the boxes and just gives me the opacity to latest boxes. What i try basically is to control the opacity by distance.

Means, each last 3 for example to keep the opacity like your example, but need to me change all this.

Example:

We have 10 boxes: Last 3 opacity like your example.

We back the touch a bit, so we have now 5 boxes.. Same as above, last 3 opacity.

All it's about touch distance between first creation and touch.x touch.y

Maybe it's a bit complex, but basically this is the main reason, this is what looking.

Thanks again for your time and help!

Something like this?

For each created box, check if the distance is farther from the origin than the touch distance. If it is, set opacity to an inverse function with x, where x is the distance from touch (as distance increases, opacity decreases, normalized between 0-100).
