Reflection of class on Nov. 3rd

  As we all know, most interactive games utilize powerful logical system to improve players’ participation and interest, that is, they provide different modes or choices for players to choose and each one could lead to a unique consequence just like the Raspi’s Cave Adventure.

  But designing a complex logical interactive game and achieve it by programming are not easy, we should consider comprehensively and be prudent to every line of codes we would create. So, we need to work out a plan by drawing a flow diagram for the whole game first to make the later programming process a little clearer. We can use a diamond shape to represent each decision, a rectangle shape to represent each consequence and a round rectangle shape to represent each final output of decision. Absolutely, these different shapes are connected by arrows which represent the possible available choices and point to the result of each choice.

  After the flow diagram was finished, we should use Python 3 to program the whole game. We are programming a complex logical game, so the if statement is the most important statement to help us get an anticipated result. But the problem is that sometimes players may input some unexpected information which could lead to the wrong result, so we need to use Boolean logic operators such as and, or and not to maximize the inclusion of if statement by correctly identifying the choice of players automatically.

  And what’s more, the simple if statement is completely not useful for the complex game, so we need to use nested if statements to check three or more available choose given by players. The key point here is that we must pay attention to the format of each line of nested if statements inside that each line of sub-statements should be indented four spaces from the beginning of if or elif command words. In addition, do not forget to add colon in the first line of each nested if statements otherwise the wrong mention sentence would display on the screen if we debug the program.

  Actually, what I feel excited in this chapter 5 is that I can make my own functions to organize code and avoid repeating codes by using def command. I can decide if my own function could output a return value or not and customize the details inside to achieve some particular purpose. I just define some particular functions and utilize them for practice when I explore the right cave in Cave Adventure. As you know, I spent a little more time on programming the right cave to practice my own functions. Fortunately, the entire program I have coded works very well. An excellent class!
