I am creating icons from images and then assigning them to objects. Im tring to figure out a way to find out whether the icon is null or if its blank because sometimes I get a blank icon whilst other icons display on the object. I want to make it so when I click on the blank icon it will check whether its blank or not. Note the user will see a blank icon which can be clicked
None of the above works, i just get world<<"() clicked" whether the icon displays or not.
Anyone know how to do this ?
Any help would be great, thanks
