[CC - 3.3.2] - How to detect 2D node from a given Coordinate

Hello fellow CC Devs!

I have an issue…

I assigned a global mouse events like this:

systemEvent.on(SystemEvent.EventType.MOUSE_DOWN, this._mouseDown, this);
systemEvent.on(SystemEvent.EventType.MOUSE_UP, this._mouseUp, this);
systemEvent.on(SystemEvent.EventType.MOUSE_MOVE, this._mouseMove, this);

I want to some how “raycast” the ui mouse position so I detect the a which node is intersect with it.
Is that possible?

The reason I am doing this is because “MOUSE_MOVE” event is only apply on the node and it is not good for me… :frowning:

I can ask engineering to have a look.

You can use this demo to test and see if it is the effect you need.

Its not really working…
However, based on the code, this is not What I need.

Lets say I am hovering the mouse and then the mouse cursor is on a node or object.
In 3D I am using ray cast to detect this.

In 2D, How will I accomplish it?

Your component is doing something else… nice one, but not what I needed… :frowning:

Look at this demo again
It’s closer to what you need, I use 2D collision detection to detect nodes.
