What is the "TRANSFORM EVENT"?

[Taka]

I am trying to create a plugin like this link.

Photoshop event delay and UXP batchPlay

I’m making a plugin where if you select something with a marquee or lasso and move it, it will move that selection on all layers. I’m using a few event listeners and using batchPlay to perform actions when some events happen (cut, set and move events). This works fine but I noticed how Photoshop will only fires those after you click away. So if you move a selection on a layer it only gives the toolModalStateChanged and historyStateChanged which don’t contain any useful information about the sele…

However, I faced the same problem.
What is the “TRANSFORM EVENT” indicated in the solution?

Hi Taka,

From memory, I would have been using batchPlay that looked something like the example here, with the action being transform:

Transforming the active layer via batchPlay() does nothing, returns no error messages

Before asking this, I checked here and here to get an idea of how to construct things. It seems that, for a layer transformation to work via batchPlay(), I need to have the active layer selected (which I do), and I need to specify the target layer ID in the action descriptor. So I cast the action descriptor as a function return value: function eventTransformSelection(id, horiz = 0, vert = 0, scale = 100) { return { "_obj": "transform", "_target": [ { _ref: "layer", …

You can get more info about events using something like the Alchemist plugin or using a listener function like that in the batchPlay documentation

Thank you for your reply, jessica!

However, I still do not understand…

I had thought that moving a selection on a layer would provide “TRANSFORM EVENT” instead of “toolModalStateChanged” and “historyStateChanged”.

However, I noticed that “transform” is provided by performing another action (e.g. selecting another layer or clicking elsewhere) after scaling, rotating, etc.

If I want to record a “cut event” immediately after moving something, should I do a deselect?

I think you are trying to do this

async function moveSelection() {
   const result = await batchPlay(
      [
         {
            _obj: "cut",
            _target: [
               {
                  _ref: "channel",
                  _property: "selection"
               }
            ],
            to: {
               _obj: "offset",
               horizontal: {
                  _unit: "distanceUnit",
                  _value: 0
               },
               vertical: {
                  _unit: "distanceUnit",
                  _value: -37.5
               }
            },
            _options: {
               dialogOptions: "dontDisplay"
            }
         }
      ],
      {
         synchronousExecution: false,
         modalBehavior: "wait"
      }
   );
}
async function runModalFunction() {
   await executeAsModal(moveSelection, {"commandName": "Action Commands"});
}

await runModalFunction();

Thank you for your reply, JasonM!

The command you wrote appears to be just something that does a cut event.
What I would like to implement is the function to record the event when the user moves something and execute that event on other layers.

I’m facing a problem that I can’t get that cut event until after I do some operation in that case.

[JasonM]

I see…I do not know how to do that

Hi Taka,

Sorry for the delay and unhelpful previous response.

Because I was having trouble with firing these events after a “move”, instead of listening for a “move”, I switched to listening for a transform event (ctrl + T, and hitting enter when finished) instead. This also had the benefit of not just necessarily performing a translation but also for any rotation, scaling etc. could also be done to the other layers as well. But unfortunately didn’t end up pursuing it after a “move” as I didn’t have any success forcing it without performing another action. I hope that makes more sense.

Best of luck!

[JasonM]

If you store the selection, and then they use Transform (ctrl T) to move the selection, you can then likely reselect that selection on the other layers and perform the last transform.

 await batchPlay(
      [
         {
            _obj: "transform",
            _target: [
               {
                  _ref: "layer",
                  _enum: "ordinal",
                  _value: "targetEnum"
               }
            ],
            lastTransform: true,
            _options: {
               dialogOptions: "dontDisplay"
            }
         }
      ],
      {}
   );

@jessica
Thank you so much!
Your explanation helped me understand.
I guess it is still difficult to get movement events

@JasonM
And thanks Jason!

I will try to make plugin with a transform event!
