Hi,

I’m trying to change brush hardness with Batchplay but no matter what I do, other parameters are being affected as well. For example size is being changed automatically to 25.  
I want to adjust hardness only and keep spacing and size (diameter) unaffected.

This is the batchplay code I’m using:

```auto
{
  _obj: 'set',
  _target: [{_ref: 'brush', _enum: 'ordinal', _value: 'targetEnum'}],
  to: {
    _obj: 'brush',
    hardness: {
      _unit: 'percentUnit',
      _value: 0
    }
  }
}

```

Anyone have the solution for that?

Thanks!

To reliably change just one settings, you need to set back the whole tool options descriptor like I’ve described here:

> I figured it out… const toolOpt: PaintBrushToolOptionsDescriptor = getAppProperty('currentToolOptions') as PaintBrushToolOptionsDescriptor toolOpt.$opVr.minimum.\_value = 50 const desc = { \_obj: 'set', \_target: { \_ref: [{ \_ref: 'paintbrushTool'}], }, to: toolOpt } photoshop.action.batchPlay([desc], {}) 3 Notes: You can ignore the types if you’re not using typescript, although I highly recommend it to know what’s going on inside the descriptors. For a different t…

To save you some time:

```auto
// ... require batchPlay & executeAsModal

// Have your tool selected or select it via:
executeAsModal(() =>
  batchPlay([
      {
        _obj: "select",
        _target: {
          _ref: "paintbrushTool",
        },
        dontRecord: true,
      },
    ],{})
);

// Store current tool options
const toolOpt = batchPlay([
  {
    _obj: 'get',
    _target: [
      { _property: "currentToolOptions" },  
      { _ref: 'application', _enum: 'ordinal', _value: 'targetEnum' }
    ],
  },
], { synchronousExecution: true })[0].currentToolOptions

// Set new value
toolOpt.brush.hardness._value = 50

// Write it back to the tool options
executeAsModal(() => batchPlay([
  {
      _obj: 'set',
      _target: {
        _ref: [{ _ref: 'paintbrushTool'}],
      },
      to: toolOpt
    }
  ],{}))

```

What does this do? 🤔

I have no idea. Maybe one time it was set for every tool select event whether it should be recorded in Actions or not, until they moved it to this setting:

Just blindly guessing though…
