| // | |
| // To make an invisible Button: | |
| // | |
| // 1. make a Button in the normal way | |
| // 2. delete the "Text" GameObject which comes below a Button as standard | |
| // 3. delete the "Image" which comes on a Button as standard | |
| // 4. drop this script on the Button, which lets the Button get touched | |
