Random Delete tool with Scriptographer

[Gernouille]

Hi, I am trying to refine the RandomTools created for Scriptographer so that it suits my preference, but I can't figure it out in Javascript. Not knowing a lot of Javascript don't help me either!

Here is the script, simplified to conserv only the Delete part. What I would like to do is to enter a percentage, and then this would be the percentage of selected object removed.

If anyone would point me to a direction with that, It would be really great.

script.coordinateSystem = 'bottom-up';
script.angleUnits = 'radians';
var sel;
var values = {
          b_delete: true,
          val_deleteAmt: 2,
};
// gui components
var components = {
          b_delete: { 
                    onChange: function(value) {
                              components.val_deleteAmt.enabled = value;
                    }
          },
          val_deleteAmt: { 
                    type: 'number',
                    fullSize: true,
                    enabled: true
          },
          deleteRule: { 
                    type: 'ruler',

                    value: 'Apply',
                    onClick: function() {
                              Main();
                    }
          }
};
// Setup
function Setup() {
          // initialize the palette window
          var palette = new Palette('Random Delete 0.5', components, values);
}

// Main
function Main() {
          // document properties
          sel = activeDocument.getItems( { type: Item, selected: true } );
          //adjust delete range values based on selection number
          components.val_deleteAmt.range = [0, sel.length-1];
          // loop through selected items
          for ( i in sel ) {
                    var object = sel;
                    if( object.isValid() ) {

                              if ( values.b_delete ) {
                                        rand = parseInt( Math.random()*values.val_deleteAmt );
                                        if (rand == 0) object.remove();
                              }
                    } //end isValid()

you should post your question in the Scriptographer forum, you may have better chances of getting help.

I will do that, but I don't know if the community is still very active there…

And here is the file, if someone want to give it a try!

Right now, the script will delete a random number of items, depending of the number you give in the dialog box, and the number is somehow in relation with the quantity of items selected.

I would like it to delete a given percentage of the items, no matter how much are selected.

I had some help from the Scriptographer forum, and here is the final stuff!

Can you point out what it does (not) do that it should (not) do?

(You seem to be using val_deleteAmt as both a range and 'as is', i.e. a single number, but that may just be something of Sg.)
