Buttons at zero position.z height not responding in Beta v14 but worked in v13#2655

This may not be a bug but thought I’d document it because it took me a while to figure out why some buttons stopped working in some of my mods in the Beta v14.

If you have a XML UI attached to an object with panel to the side of the object (such as a main board tile or a player board tile) that has Button tags in it and that panel has a position Z height of zero so it is flat against the table it will be rendered (you can see it) but it recieves no mouse pointer interaction at all. No click events are triggered, no hover state change, etc.

Load the same mod in v13 and the button events work as expected.

This is easily fixed in the v14 Beta (once you know why) by just raising the Z position value of the panel containing the button(s) to -10 or so. Raising even less may work but that’s what I did and buttons work as expected.

Again maybe not a bug so I am setting the type to “Technical Issue”. Perhaps this is the Unity/TTS environment doing exactly what it’s supposed to do and the prior version should not have worked but maybe this will help someone else who is wondering why buttons stopped working.

Screenshot of an example of buttons positioned as I’m describing above. These buttons are in XML UI attached to the main board to the right.
