Atributes?earthquake and other

Hello! I have a question, or rather 4 questions. 1- How can you make the attribute information that will appear when you hover the cursor on the model ?. 2- how to highlight individual models so that they are visible through the rest? and how to make a change in weather conditions when you press a button on the htc controller or keyboard. And last - Is it possible to make a simulation of an earthquake, if so, how? Thank you friends
