panel - set draggable bounds to arc?

@Dan-Korneff If you want anything following a path of any shape, the solution is in this pull request which hasn't yet been merged:

[Dan Korneff]

@ustk Thanks so much for the help!

@Christoph-Hart @ustk show me the way :)

[ustk]

@Dan-Korneff Yeah I've just seen the merge
@Christoph-Hart :thumbs_up:

[ustk]

@ustk I'll try to make an example...

In short, create a path, get a point along the path length (which is a 0-1 value), do whatever with the coordinates

[Dan Korneff]

Here's my sad attempt:

// Add a mouse callback to the panel to drag it along the arc
Panel1.setMouseCallback(function(event)
{
    if (event.drag)
    {
        // Calculate the angle between the center of the panel and the current mouse position
        var dx = event.x - 300;
        var dy = event.y - 300;
        var angle = Math.atan(dy / dx);

        // Adjust the angle
        if (dx < 0)
        {
            angle += Math.PI;
        }

        // Calculate the new position of the panel on the arc
        var radius = 200;
        var pX = radius * Math.cos(angle) + 300 - Panel1.getWidth() / 2;
        var pY = radius * Math.sin(angle) + 300 - Panel1.getHeight() / 2;

        Panel1.setPosition(pX, pY, Panel1.getWidth(), Panel1.getHeight());
    }
});

@Dan-Korneff What's the reason you want to use a draggable panel and not a knob?

[Dan Korneff]

@d-healey I'm using a knob + filmstrip right now, but the dragging and tracking isn's as smooth as I'd like. Especially near the far ends of the range.

Not directly related, but with the additional path methods from the last commit, you can follow any path:

@ustk nice!! Watch out, weird controls ahead

[d.healey]

@Dan-Korneff Did you try changing the mouse sensitivity setting, and perhaps set drag direction to horizontal.

[Dan Korneff]

@d-healey I did... that's the best I could get. It's also not ideal that you can click anywhere on the filmstrip (not just the image of the slider) to change the slider position.

[ustk]

@Dan-Korneff Is your attempt above working as you wish?

[Dan Korneff]

@ustk That's pretty neat!!

My above attempt doesn't work as intended. The panel doesn't follow the mouse drag properly

[ustk]

@Dan-Korneff Yeah so I think it might be related to the panel itself moving as you drag, so the mouse drag info might not be consistent...

[ustk]

@Dan-Korneff Another solution I implemented a while ago is to create some mouse masking.

you define a smaller and a bigger circle, and only accept a mouse click to be valid when you click in between the two.

@Dan-Korneff With the new path methods, it is also possible to detect if a mouse is inside or outside a path with Path.contains([x,y])
