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!

Correct answer Vladin M. Mitov

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 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' );" );

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

got it, this means that I cannot add these events in my customized panel, but need to use the add extension tool to achieve

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?

no such event for fl. check the api.

Thank you for your answer，this method is used in the API, but I don't know how to use it

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

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.
