Study 7 is a improvement based on my study 5, I made a mini game again, the teacher helped me a lot, to complete my idea, and some professional operation. There is a major character and many apples, and the apple will fall down, visitors can use the arrow key to control the major character to avoid those apples. After making this program, I can set a control key by myself, and also learned how to make the object decrease and increase automatically. Indeed, there are many shortcoming of this program, when I showing this to my friend and they playing that, they told me there are some place that the character can always avoid the apple and doesn’t need to move, and the apple always falling in the same line so that will be a little bit boring, also they mentioned that when the character touched the apple, the ‘fail’ sound is not sensitive enough, which is not a completed game. I’m satisfied with my study 7, the idea was better than study 6 and also I made my effort on it.
