Do you have raycast target enabled on the text?

Ok - for debugging: Waking up ･ﾟ✧

The button works flawlessly with the debugbutton&console url but not the original url I posted, what’s up there?

I’m heading off for the day now but hoping to get to the bottom of this monday, I’ll just delete the text object if needed just so it works but I’m not sure what’s going on

This sounds like an issue I had a while ago where the button would work fine in a browser but not in VR. The issue was that other elements in the button were getting the click (i.e. the text element instead of the background) . The solution was to prevent the button text from getting clicks but i can’t recall the details

Looking back through the forum posts and I had to remove the raycastTarget from everything but the active part of the button.

I disabled raycast target already so must be something else or that property on the Text component isn’t exporting

I can confirm the text object doesn’t cause it as I deleted the text object, the button only presses on mobile if you long press it then release after which is weird

Was caused by doubled up touch events, should be fixed in a new Needle version
