What you want is this

https://docs.unity3d.com/ScriptReference/UI.Image-alphaHitTestMinimumThreshold.html

Make a script that changes alphaHitTestMinimumThreshold (For the Image component that your button uses) at start, to something other than 0 (Like 0.5f). Then the transparent parts of the image won’t trigger the button when you click on them.

Hi my friend.../this code not work for me:/ please help! my unity version is 5.5.1! how use this code!.......................................i normal use & not working! ................................................ public Image theButton; void Start() { theButton.alphaHitTestMinimumThreshold = 0.5f; } //why?

This is done using an Image Mask or UI Mask.
