Hi,
I was wondering what algorithms people used for the rotary wheel. I have played with the simple exponential one in the Dev Guide and find that it doesn't work for me with a relatively short list of songs. I thought it would be useful to start a list of them here and see what people have used?

Any ideas?

Thanks

I made a long list of movie names. It would display 20 names at a time.
I set it up to skip 10 lines at a time.

onRotary = function(clicks) {
if (clicks > 1) {
     // Skip 10 lines
     } ;
} ;

In my Chanel Blaster in Project Boredom 2  [Link: mediafire.com] , I did something different like . . .

if (clicks > .99) {
defaultchannel ++ ; // up one
} ;

if (clicks > 1) {
defaultchannel +=10 ; // up 10
} ;

if (clicks < -1) {
defaultchannel -- ; // down 1
} ;

It's not a algorithm , but it worked .

Note that with the above code, you are actually skipping 11 channels on a clockwise turn when clicks > 1 as both (clicks > 1) and (clicks > .99) will return true.

if (clicks > 1)
channel +=10;
else if (clicks > 0)
channel++;
else if (-1 > clicks)
channel-=10;
else if (0 > clicks)
channel--;
else
{
// do nothing as (clicks === 0)
}

Hear is the script I use when I have a long list.

You have 3 differents speed.
- 1 by 1
- I add the click value
- I multiply by click value

So quicker you turn the rotary quicker the list go down.

I use also a cursor (an indicator of the selected line).

{
if(clicks > 0)
{
if(Selected_Item < (nbL-1))
{
CF.widget("lst_"+Selected_Item).setImage(CF.widget("btnOFF","GALLERY").getImage(0),0);
CF.widget("lst_"+Selected_Item).setImage(CF.widget("btnOFF","GALLERY").getImage(1),1);
CF.widget("lst_"+Selected_Item).stretchImage = true;
Selected_Item ++;
CF.widget("lst_"+Selected_Item).setImage(CF.widget("btnON","GALLERY").getImage(0),0);
CF.widget("lst_"+Selected_Item).setImage(CF.widget("btnON","GALLERY").getImage(1),1);
CF.widget("lst_"+Selected_Item).stretchImage = true;
}
else
{
if(clicks>0 && clicks <3) // Pas de 1
{
if(decale_a}
if(clicks>=3 && clicks <5) // Pas de Click (On ajoute click)
{
if(decale_a}
if(clicks>=5) // Fois de click (On Multiplie par click)
{
if(decale_a}
}
}
if(clicks < 0)
{
if(Selected_Item>0)
{
CF.widget("lst_"+Selected_Item).setImage(CF.widget("btnOFF","GALLERY").getImage(),0);
CF.widget("lst_"+Selected_Item).setImage(CF.widget("btnOFF","GALLERY").getImage(),1);
CF.widget("lst_"+Selected_Item).stretchImage = true;
Selected_Item --;
CF.widget("lst_"+Selected_Item).setImage(CF.widget("btnON","GALLERY").getImage(),0);
CF.widget("lst_"+Selected_Item).setImage(CF.widget("btnON","GALLERY").getImage(),1);
CF.widget("lst_"+Selected_Item).stretchImage = true;
}
else
{
if(clicks<0 && clicks>(-3)) { if((decale_a-1)>=0) { decale_a = decale_a - 1; } }
if(clicks<=(-3) && clicks>(-5)) { if((decale_a+clicks)>=0) { decale_a = decale_a + clicks; } else { if((decale_a-1)>=0) { decale_a = decale_a - 1; } } }
if(clicks<=(-5)) { if(decale_a+(clicks*nbL)>=0) { decale_a = decale_a + (clicks*nbL); } else { if((decale_a-nbL)>=0) { decale_a = decale_a - nbL; } else { decale_a = 0; } } }
}

if(decale_a>nbArtist-nbL) { decale_a = nbArtist - nbL }
Display_List(nbL);
