I guess after more googling the only way is to select a tool preset. Problem is that I want to share the action with coworkers not having to worry about if they have the same tool-presets as me (or rename/delete them).

 

Would it be possible to modify this script to set a tool preset for brus 150px and opacity 20% ? I can try myself but I am kind of new in scripting so I need som guidance.

Have you tried using the script listener pluging? ADOBE PHOTOSHOP SCRIPTING. It will record everything you do in photoshop, except changing zoom levels. Turn it on, turn your opacity down, turn it off. Check your desktop for a log file named something like "Scriptlistener.log" and inside there will be the code to do whatever you've just done inside of photoshop.

This is really useful, but where did you find all those string IDs in the getBrushFeatures() function? 

brush

diameter

hardness

etc

Yes, they make sense, but so does "brushDiameter" instead of "diameter" and it's hard to know what PS is looking for with string IDs.

You can for example find them in some brush preset after saving it to disk and reading its binaries.

I'm not looking for presets, I don't think.  It looks like the getBrushFeatures() function is grabbing these string IDs from "currentToolOptions" and I'm trying to find the current tool options for several different tools, not just brushes.

Then start from this:

sTT = stringIDToTypeID; (ref = new ActionReference()).putProperty

(sTT('property'), sTT('tool')), ref.putClass(sTT('application'))

executeActionGet(ref).getObjectValue(sTT('currentToolOptions'))

JJMack, Thank you for such a helpful script! But I have a trouble with Scattering. It's automatically toggle on with setPaintBrush function. Have no idea why and how to fix that... Maybe you can advice?

Hooray! I solved. Added this code after desc5.putUnitDouble in //flow section of setPaintBrush function:

  // scattering

  var id191 = stringIDToTypeID( "scatter" );

  desc5.putUnitDouble( id191, id14, scatter );

The function should not chage the brush Scattering from what the I see function parameters

// parameters (mode character string, opacity %, flow %, penopacity boolean, pensize boolean, penair boolean) all are required 

function SetPaintBrush(mode,opacity,flow,penopacity,pensize,penair)

Mode blendind type, Opacity how opaque, Flow rate

seems to set and the others seem to be True/False for the brush tool Option bar pen controls

Opacity presure, Size transfer pen controled, and Airbrush mode

The three toggles are Shape Dytnamics, Transfer and Buildup

The Current brush Scattering should not change

I see nothing in the function action manager coder that address Scattering

var idset = stringIDToTypeID( "set" ); 

  var desc226 = new ActionDescriptor(); 

  var idnull = stringIDToTypeID( "null" ); 

  var ref170 = new ActionReference(); 

    var idPbTl = stringIDToTypeID( "paintbrushTool" ); 

    ref170.putClass( idPbTl ); 

    desc226.putReference( idnull, ref170 ); 

    var id12 = stringIDToTypeID( "to" ); 

    var desc5 = new ActionDescriptor(); 

    // opacity 

    var id13 = stringIDToTypeID( "opacity" ); 

    var id14 = stringIDToTypeID( "percentUnit" ); 

  desc5.putUnitDouble( id13, id14, opacity ); 

    // blend mode 

    var id15 = stringIDToTypeID( "mode" ); 

    var id16 = stringIDToTypeID( "blendModel" ); 

  var id17 = stringIDToTypeID( mode ); 

    desc5.putEnumerated( id15, id16, id17 ); 

    // flow 

    var id19 = stringIDToTypeID( "flow" ); 

  desc5.putUnitDouble( id19, id14, flow ); 

    // pressure for opacity 

    desc5.putBoolean( stringIDToTypeID( "usePressureOverridesOpacity" ), penopacity ); 

    // pressure for size 

    desc5.putBoolean( stringIDToTypeID( "usePressureOverridesSize" ), pensize ); 

    // enable air brush 

    desc5.putBoolean( stringIDToTypeID( "repeat" ), penair ); 

    var id18 = stringIDToTypeID( "null" ); 

    desc226.putObject( id12, id18, desc5 );

In JavaScripts you said "I currently have 1354 JavaScript files and I will be adding them here after I clean them up.", but after 6 years there are less than 10 uploaded scripts. Could you add some more?
