FlipX of brush using script

Hi! This should be really simple, all I need to do is toggle flipX (in Brush Properties) using a script.

This was my attempt:

var desc = new ActionDescriptor();
desc.putBoolean(stringIDToTypeID('flipX'), true);
executeAction(desc);

It brings an error for line 3 saying a numeric value is required.

 

I tried some code from this link: https://community.adobe.com/t5/photoshop-ecosystem-discussions/brush-kind-tools-spacing-is-always-25...

 

Which works, but switches to the Airbrush instead of the brush I currently have. Any help? 🙂

Do you have experience with AM code programming?

No? Then you should definitely use the complete code from the linked topic!

 

Then it will work as desired.

This doesn't seem to work with brushes that have the hardness setting greyed out.

I just want a script that flips X of any brush.

In this case you can permanent "disable" --> comment out the two following lines:

if (Hardness == undefined) Hardness = brushDesc.getDouble(stringIDToTypeID('hardness'));    

and

desc1.putDouble(stringIDToTypeID('hardness'), Hardness);

I already tried that, it doesn't work. It just switches to the airbrush.

Sorry, but the code seems to be a dead end. It always changes the tool.

 

I don't have the experience to recreate it and I don't have the time to adapt it to the tool currently in use.

Maybe someone else will find a suitable solution.

Hi @jazz-y,

you are one of the few I have pinned my hopes on.

😉

 

Your code works for me. Let's wait and see if the OP gets back on that too.

Works perfectly, thank you very much. So much code to do such a simple thing, although I imagine some of it is to get around the brush not having hardness, I'm not sure. AM code is a funny thing 😛

In fact, this code is similar to what the @pixxxelschubser wrote above.

The difference is that I save all the current brush settings to a variable, change flipX property, and write the brush variable back to the tool settings. The code above tries to completely recreate the brush based on a hard-coded set of parameters, and accordingly if the active brush contains more parameters (for example, sampling data for mask-based artistic brushes) or less (as we found, the brush may not have a hardness parameter), then this leads to unexpected results.
