How to obtain the coordinates of mouse clicks on stage in JSFL?

I have rewritten these two methods in the jsx file without any effect

 

function mouseDown() {
    fl.trace("Mouse button has been pressed");
}
function mouseDown(pt) {
    fl.trace("x = "+ pt.x+" :: y = "+pt.y);
}

 

This method may also report errors

 

 fl.addEventListener("mouseDown", myFunction);

 

Thank you very much if you can!

Hi.

 

These methods are for extensible tools: activate(), configureTool(), deactivate(), keyDown(), keyUp(), mouseDoubleClick(), mouseDown(), mouseMove(), mouseUp(), notifySettingsChanged(), and setCursor().

 

The PolyStar tool uses the structure/code of an extensible tool. You can find it in:

<ADOBE_ANIMATE_INSTALL_FOLDER>/<LANGUAGE>/First Run/Tools

JC

If you want to implement shape creation with JSFL, I recommend examining the script PolyStar.jsfl located in the Tools subfolder. It demonstrates the correct usage of mouseDown(), mouseUp(), and mouseMove().

I advise against subscribing to the mouseMove event. While technically possible, I believe it is not a good practice. I have seen panels that degrade the overall program performance because they subscribed to computationally intensive functions on mouseMove.

If you want to incorporate drawing

fl has that method, but not that event.  further there is no jsfl object that has that method and event.  ie, use an on-stage object.

Thank you, got it.  another problem, this event is ok, with log output

function onMove() {
  fl.removeEventListener("mouseMove", myFunction)
}

function myFunction() {
  fl.trace("move");
}

But this is not output log 

function myFunction(pt) {
  fl.trace("x = " + pt.x + " :: y = " + pt.y);
}

I see that the API has this method, may I ask how to write it, Thank you again

myFunctions argument is the event, not a point, assuming you're using a mousemove event listener

Sorry, I made a mistake in copying, It should be this code

fl.addEventListener("mouseMove", myFunction);

I changed it to event

function myFunction(event) {
  fl.trace(event);
}

but log print  undefined

Using an extensible tool is probably the best way to track the cursor position. Listening to the "mouseMove" event is also possible, although I think it's kinda tricky to use it.

 

But what exactly do you need to do?

If you want to incorporate drawing as a functionality in your panel, write it as a tool script, and then integrate it appropriately in the panel using:

 

MMExecute( "fl.selectTool( 'yourCustomToolName' );" );
