can anyone make me a Script

Hi Dario, 

Can you give a little bit more context about what you're trying to achieve?

At high level, what you want to do: 

1. Add a Touch component to your object so that it can receive touches
2. Add a Script component to your object and select "Tapped" in the drop down so that it gets called when the user taps
3. In the script pass in your material
4. Get your object's (first) MeshVisual component
5. Tell your MeshVisual component to clear the old material and add the passed in material 

If you need more help, please let me know which area I can help you with.

Thanks!

Jon
