Title: Invisible UIButton that can still be clicked
Post by: bach on August 21, 2014, 08:09:54 AM

I need to setup an invisible UIButton that when pressed,
I display a sprite to show that it's been touched.

When I set the Alpha to 0 in Colors > Normal
The click event no longer fires.

Is there a way to have the
Normal Sprite transparent
Pressed Sprite Visible
and still have the Click event firing?

thanks

Set alpha to 1, it won't be visible but it will work :)

alpha == .001 should still fire event and be invisible

Oh correct, I forgot alpha is from 0 - 1.. I am used to 0 - 255

Thanks guys, you're both right.

In my case i have set the Alpha for the Normal Color to 1 (hex color)
that made it invisible and still picked up the touch. Thanks for the tip

For the pressed State I kept it's Color Alpha to 255
works great thanks again!
