Difficult functions and programming thinking

Throughout the project, we designed an App that allows you to play the "Bobing" game with very simple operations. Features are focused, with a focus on "Bobing" gameplay. We think the difficulties in the process are:

1. We wanted to make the dice move rather than just get a static result. Finally, we decided to make the pictures of the dice with different points alternately appear at different six dice to achieve a more humane dynamic effect.

One of a number of dice in which images alternate with different rolls

int a = Math.abs(SecureRandom.getInstance("SHA1PRNG").nextInt()) % 6 + 1;
                                    int b = Math.abs(SecureRandom.getInstance("SHA1PRNG").nextInt()) % 6 + 1;
                                    int c = Math.abs(SecureRandom.getInstance("SHA1PRNG").nextInt()) % 6 + 1;
                                    int d = Math.abs(SecureRandom.getInstance("SHA1PRNG").nextInt()) % 6 + 1;
                                    int e = Math.abs(SecureRandom.getInstance("SHA1PRNG").nextInt()) % 6 + 1;
                                    int f = Math.abs(SecureRandom.getInstance("SHA1PRNG").nextInt()) % 6 + 1;

mView.findViewById(R.id.imageView3).post(new Runnable() {
                                        @Override
                                        public void run() {
                                            ((ImageView) mView.findViewById(R.id.imageView3)).setImageResource(getDice[a]);
                                        }
                                    });

2. We believe that the second difficulty lies in how to make the numbers thrown out of the dice correspond to the result images displayed. Finally, we used array correspondence to solve this problem.

Pair programming experience
In this experiment, we started to touch the front-end development software, designed Ul, learned to use Axure for some interactive operations, and used Android studio for programming and running. I learned a lot from this collaboration. Teamwork is very important, and group cooperative learning is more conducive to students' independent thinking. The cooperative group is based on the premise of voluntary grouping of students, and then adjusted according to the large differences in the learning degree among the teams, so that the teams can achieve a basic balance in human resource allocation. At the same time, in programming, many people's different ideas and actions can better check and improve the code.

Long time events

1. Code

We chose the more convenient Android studio to complete this project, but we are not familiar with Java and xml format interface design

2. Interface

How did we spend a lot of time in making the dice show the dynamic effect of Chu Yizhong in the process of rolling dice

3. Record

We are assigning the game a score and storing the data to achieve the competitive nature of the game. Again, it took a long time
