I've read about the "performance tips", But I still have several questions:
1. Now I know that we shouldn't use too much sprites, But what about the instances of one sprite? should we avoid to use it too much?
2. I didn't understand, what is the difference between a text sprite and a text box...In fact, I'm using lots of text box...
3. I still can't find where we could set the Framerate? Like, I want to make a game for the Moblie device, how could I set the Framerate to 30fpt, please?
Thanks in acvance
