How do I raycast from a UI object? I have tried
Ray ray;
Camera cam;
Transform obj; //UI object
ray = cam.ViewportPointToRay(obj.position);
AND
ray = new Ray(obj.position, obj.forward);
Neither of these seem to work.

\$\begingroup\$ Not an answer but you can debug your ray if the ray is hitting correct target or not. To debug ray user "Debug.DrawRay". for documentation : docs.unity3d.com/ScriptReference/Debug.DrawRay.html \$\endgroup\$– SwatiOct 11, 2019 at 5:47

\$\begingroup\$ How are you using these rays, and what is the specific symptom of "not working" that you're facing? The code you've shown us so far looks perfectly correct for some purposes — if it's not doing what you want then it sounds like your purpose is something else, so tell us about that gap. Be sure to include details of your scene setup like what mode your canvas is using.— one version looks like it's written for screen-space, the other for world-space, so we need to know what you're actually trying to use it for. \$\endgroup\$– DMGregory ♦Oct 11, 2019 at 6:04

I've figured it out:
ray = cam.ScreenPointToRay(obj.position);
