How to Set Current Tool Opacity to 100%?

[arteangelus]

Hello, I'm trying to set opacity of paint brush tool to 100%. I tried many ways but could not find it, I tried to record an action but it did not record. Then I installed scriptlistener and got script below but it does not work either. It throws an error at the last line ;

executeAction( idtoolModalStateChanged, desc69, DialogModes.NO );

Here is scriptlistener's output;

var idtoolModalStateChanged = stringIDToTypeID( "toolModalStateChanged" );
    var desc69 = new ActionDescriptor();
    var idLvl = charIDToTypeID( "Lvl " );
    desc69.putInteger( idLvl, 0 );
    var idStte = charIDToTypeID( "Stte" );
    var idStte = charIDToTypeID( "Stte" );
    var idexit = stringIDToTypeID( "exit" );
    desc69.putEnumerated( idStte, idStte, idexit );
    var idTool = charIDToTypeID( "Tool" );
        var desc70 = new ActionDescriptor();
        var idIdnt = charIDToTypeID( "Idnt" );
        desc70.putString( idIdnt, """pntb""" );
        var idTtl = charIDToTypeID( "Ttl " );
        desc70.putString( idTtl, """Brush Tool""" );
    var idTool = charIDToTypeID( "Tool" );
    desc69.putObject( idTool, idTool, desc70 );
    var idKnd = charIDToTypeID( "Knd " );
    var idKnd = charIDToTypeID( "Knd " );
    var idPnt = charIDToTypeID( "Pnt " );
    desc69.putEnumerated( idKnd, idKnd, idPnt );
    var idkcanDispatchWhileModal = stringIDToTypeID( "kcanDispatchWhileModal" );
    desc69.putBoolean( idkcanDispatchWhileModal, true );
executeAction( idtoolModalStateChanged, desc69, DialogModes.NO );

I've searched but could not find an exact answer.

(Note: In my main script I aim to create a work path point then apply a stroke with paint brush tool. So It would be still useful if there's a way to paint with a brush which has 100% opacity.)

Thanks and Best Regards.

Many things you can do in Photoshop are nor record-able in Actions. If something can not be recorded in an action the Scriplistener Plug-in will not record anything either for it record action manager code.   Adobe introduce tool recording a few release ago you may be able to record brush opacity changes with that feature. I do not use this feature for I do not find it useful for general work. It only woks well on same size documents.   However, if you install the scriptlistener plug-in Adobe will disable the tool recording feature.

You best bet is to use Prush Presets Opacity setting should be recorded in  brush presets. You can select Brush presets in actions ant the selection will record in you action..

Hi guys,
I have this small photoshop script to change the current brush hardness which works fine, however it has a sideeffect which i cannot find the reason for.

try {
 var desc1 = new ActionDescriptor();
 var ref1 = new ActionReference();
 ref1.putEnumerated(charIDToTypeID('Brsh'), charIDToTypeID('Ordn'), charIDToTypeID('Trgt'));
 desc1.putReference(charIDToTypeID('null'), ref1);
 var desc2 = new ActionDescriptor();
 desc2.putDouble(stringIDToTypeID('hardness'),  " + size + ");
 desc1.putObject(charIDToTypeID('T   '), charIDToTypeID('Brsh'), desc2);
 executeAction(charIDToTypeID('setd'), desc1, DialogModes.NO);
 'SUCCESS';
}";
catch(e) {";
 'ERROR';
}";

 Whenever I run this script it sets the hardness correct but it also set the brush radius to 25 each time, no matter what the original radius was.

Any ideas what I am doing wrong?

Your code is malfunctional:

sTT = stringIDToTypeID; (reference = new ActionReference())
.putEnumerated(sTT('brush'), sTT('ordinal'), sTT('targetEnum'));
(descriptor1 = new ActionDescriptor()).putReference(sTT('null'), reference)
descriptor2 = new ActionDescriptor(), object = {diameter: 33, hardness: 33}
for(iterator in object) descriptor2.putDouble(sTT(iterator), object[iterator])
descriptor1.putObject(sTT('to'), sTT('brush'), descriptor2)
executeAction(sTT('set'), descriptor1)

Thank you very much for your reply, I think I made a mistake by adding this post to another, not sure what went wrong with that. Apologies 

If I read your script correctly, the thing I was missing was that I also need to add the diameter if I change the hardness (or any other attribute of the brush) ? The rest seems to be the same although with a different syntax/style.

[Kukurykus]

It seems some attributes must be set if you don't want them to be reseted to default. Ps. this is right place for yout post (that was moved), as here's Pedro Cortez Marques example code.
