How can I create a touchable button on mobile?

Is there any tutorials on this?Thanks!

As of 4.2, HUD hitboxes register touch input from mobile devices. There is a section of the content examples that deals with creating a pause menu with clickble buttons.

Thanks for the reply!
You mean the HUD level in the content example?But i cant click the buttons in the mobile previewer…Please tell me how to achieve that.thanks again

Oh i got it working after i check the enable touch events in the controller thanks very much!

Oh i come across a issue that if i click outside the hitbox first,then the first click on the hitbox will not work.The mobile and the previewer botj have this issue…Is it a bug?Thanks for your reply.

I currently do not have the 4.2 build, when I get it I will attempt to find a fix for this problem.

OK Thanks very much!
