Allow for click detection (mouse picking) of a TextSpan

[ethereumdegen]

What problem does this solve or what need does it fill?

I am rendering a Text element with many child TextNodes , some of the children are 'links' so they have a component on them that has the destination when clicked. However, it seems that the Interaction component doesnt work with a TextSpan in 0.15 . ?

What solution would you like?

Some way, with Interaction or otherwise, to be able to detect a click (trigger on an entity on mouse click) on a text span

I have tried to attach a Node and Button component to the text span but that totally breaks the text rendering.

This needs a text picking backend :)

Ickshonope says this is a potential way to impl it

It isn't too hard, once you detect a click on the UI node containing the text you just need to take the mouse position and then iterate through all the positioned glyphs in TextLayoutInfo and find which glyph the cursor was over and then you get the span index from that PositionedGlyph

But there may be a few different approaches possible as far as an in-engine soln -
